4. Audit Scope and Boundaries
The audit scope of this report is: the brand rankings and recommendation behavior generated by ChatGPT in the smart lock category across 6 attribute dimensions (security, reliability, smart experience, installation and ease of use, durability, and value for money).
This report does not include the following:
● Actual product performance test data
● Market share or sales data
● Consumer satisfaction survey results
● Product Price Rationality Assessment
● Any Form of Purchase Recommendation
This report only reflects ChatGPT’s AI output behavior under specific query conditions, and all conclusions are based on traceable conversation records. It does not represent an evaluation of the product quality of any brand.
5. Methodology Overview
This audit used an attribute-driven methodology, breaking the smart door lock category into 6 independent attribute dimensions. For each attribute dimension, one Ranking question and one Recommendation question were designed, for a total of 12 queries.
Single-attribute questioning rule: each question focuses only on one attribute dimension, without mixing multiple evaluation criteria, to ensure that the brand preference in the AI output can be attributed to a specific attribute.
Dual-track structure of Ranking + Recommendation: Ranking questions require the AI to rank brands, while Recommendation questions require the AI to provide a preferred choice in a specific scenario. Comparative analysis of the two types of questions can reveal whether there is a structural difference between AI’s "cognitive ranking" and "decision recommendation."
Multi-round sampling mechanism: this audit conducted 1 round of sampling and obtained 12 AI responses. According to Rule 3, the sampling rounds were fewer than 2, so stability could not be verified (insufficient sampling).
6. Metric Definitions
Brand Mention Frequency (BMF)
The total number of times a brand is mentioned across all responses. Multiple mentions of the same brand within one response are counted as 1. This audit included a total of 12 responses, and the maximum BMF value is 12.Top-1 Presence
The ratio of the number of answers in which a certain brand appears in first place (or as the recommended first choice) to the total number of answers. The numerator is the number of answers in which that brand receives Top-1, and the denominator is the total number of answers (12).Top-3 Presence
The ratio of the number of answers in which a certain brand appears in the top three rankings to the total number of answers. The numerator is the number of answers in which that brand ranks in the top three, and the denominator is the total number of answers (12).Recommendation Rate
In Recommendation questions (6 in total), the proportion of times a certain brand is explicitly recommended (as the top choice or a co-recommendation). The numerator is the number of times that brand is explicitly recommended in recommendation-type questions, and the denominator is 6.Ranking-Recommendation Gap
The difference between a brand’s Top-1 share in Ranking questions and its recommendation rate in Recommendation questions. A positive value means the brand performs better in ranking than in recommendation, while a negative value means it performs better in recommendation than in ranking.

9. Data Processing and Normalization
Brand Normalization Rules
● “Yale (Assa Abloy)”, “Yale Home”, “Yale Assure Lock 2” and similar expressions are all normalized to “Yale”
● “Schlage Encode Plus”, “Schlage Encode”, “Schlage Sense” and similar model names are all normalized to “Schlage”
● “August Wi-Fi”, “August Home”, “August Pro” and similar expressions are all normalized to “August”
● “Ultraloq U-Bolt Pro”, “ULTRALOQ” and similar expressions are all normalized to “Ultraloq”
● “eufy Security”, “Eufy Security”, “eufy” and similar expressions are all normalized to “Eufy”
● “Kwikset Halo”, “Kwikset SmartCode” and similar model names are all normalized to “Kwikset”
● "Nuki" is counted as a standalone brand, appearing only in Q3, and is not merged with other brands
● "TP-Link Tapo" is counted as a standalone brand, appearing only in Q12
● Expressions such as “Level Lock” and “Level Lock+” are all standardized as “Level”
Sub-brand handling method
All sub-brands or product line names are attributed to the main brand for statistics. Model names (such as Encode Plus, Assure Lock 2) are not counted separately as brand statistics units.
Data cleansing principles
● Multiple mentions of the same brand in the same answer (e.g., appearing in both the main text and the ranking list) are counted as 1 mention
● Brands that appear only in the "Important Notes" or "Notes" sections and do not enter the ranking or recommendation list are counted in BMF only if they have a clear evaluative description; otherwise, they are not counted
● In Q4, AI provided two ranking lists (overall ranking and "installation convenience only" ranking). The overall ranking was used as the primary data source. Nuki appeared only in the installation convenience sub-list, so it is included in Q4 mentions but not counted in Top-1

12. Comparative Analysis of Ranking and Recommendation
This section compares the consistency and differences between the Ranking Top-1 brand and the Recommendation first-choice brand across 6 attributes.
Consistency Cases
In the safety attribute (Q1/Q7), both the Ranking Top-1 and Recommendation first choice are Schlage, and the results for the two types of questions are exactly the same. In the installation and ease of use attribute (Q4/Q10), both the Ranking Top-1 and Recommendation first choice are August, and the results are also exactly the same. In the value for money attribute (Q6/Q12), both the Ranking Top-1 and Recommendation first choice are Eufy, and the results are exactly the same.
In the above 3 attributes, the Ranking and Recommendation results are consistent, accounting for 50% of all 6 attributes (3/6).
Difference Cases
In the reliability attribute (Q2/Q8), the Ranking Top-1 is Schlage, but the Recommendation first choice is August. In Q2, AI describes Schlage as "the reliability benchmark" and places it in 1st place, but in Q8, it lists August as the first-choice recommendation, with Schlage dropping to 2nd place. Difference magnitude: Schlage's Top-1 share in reliability Ranking is 1/1 (100%), but its first-choice share in reliability Recommendation is 0/1 (0%).
In the intelligent experience attribute (Q3/Q9), the Ranking Top-1 is August, but the Recommendation first choice is Yale. In Q3, AI described August as "Best-in-class app" and placed it first, but in Q9 it clearly stated "Yale is currently the safest recommendation." Difference magnitude: August’s Top-1 share in the intelligent experience Ranking is 1/1 (100%), but its first-choice share in the intelligent experience Recommendation is 0/1 (0%).
In the durability attribute (Q5/Q11), the Ranking Top-1 is Schlage, but the Recommendation first choice is August. In Q5, AI placed Schlage first and gave it a 9.5/10 rating, but in Q11 it listed August as the first-choice recommendation, with Schlage dropping to second place. Difference magnitude: Schlage’s Top-1 share in the durability Ranking is 1/1 (100%), but its first-choice share in the durability Recommendation is 0/1 (0%).
Analysis of difference types
Brands that perform strongly in Ranking but weakly in Recommendation: Schlage received Top-1 in the Ranking for both reliability and durability attributes, but was not the first-choice recommendation in the corresponding Recommendation questions, being replaced by August. This pattern repeats across 2 attributes.
Brands more concentrated in Recommendation: August received the first-choice recommendation in the Recommendation questions for 3 attributes (reliability Q8, convenience Q10, durability Q11), but in the corresponding Ranking questions, it received Top-1 only in convenience (Q4) and intelligent experience (Q3) attributes, and did not receive Top-1 in reliability (Q2) and durability (Q5).
"Cognition vs. Decision" bias: Across the two attributes of reliability and durability, AI places Schlage first at the ranking level (cognition) but places August first at the recommendation level (decision). This phenomenon appears in 2 of the 6 attributes, accounting for 33%. In the intelligent experience attribute, AI places August first at the ranking level but places Yale first at the recommendation level, similarly showing a separation between cognition and decision.
13. Cross-Attribute Analysis
Brand occurrence counts and attribute coverage across different attributes
Schlage appears in the Ranking questions for all 6 attributes, with attribute coverage of 6/6 (Ranking). Schlage also appears in the Recommendation questions for all 6 attributes, with attribute coverage of 6/6 (Recommendation). Schlage ranks Top-1 in the Ranking of 3 attributes: safety, reliability, and durability, and receives the top recommendation in the Recommendation of 1 attribute: safety.
Yale appears in the Ranking questions for all 6 attributes, with attribute coverage of 6/6 (Ranking). Yale also appears in the Recommendation questions for all 6 attributes, with attribute coverage of 6/6 (Recommendation). Yale does not rank Top-1 in the Ranking of any attribute, but receives the top recommendation in the Recommendation of 1 attribute: intelligent experience.
August appears in the Ranking questions for 5 of the 6 attributes (not in value for money Q6), with attribute coverage of 5/6 (Ranking). It receives recommendations in 4 of the 6 Recommendation questions (not in safety Q7 and value for money Q12), with attribute coverage of 4/6 (Recommendation). August ranks Top-1 in the Ranking of 2 attributes: intelligent experience and convenience, and receives the top recommendation in the Recommendation of 3 attributes: reliability, convenience, and durability.
Eufy appears in 4 of the 6 Ranking questions across the attributes (Security Q1 8th, Convenience Q4 4th, Durability Q5 8th, Value for Money Q6 1st), with attribute coverage of 4/6 (Ranking). It appears in 2 of the 6 Recommendation questions (Smart Experience Q9 6th, Convenience Q10 4th, Value for Money Q12 first choice), with attribute coverage of 3/6 (Recommendation). Eufy achieved Ranking Top-1 and Recommendation first choice only in the Value for Money attribute.
Ultraloq appears in all 6 Ranking questions across the 6 attributes (Security Q1 3rd, Reliability Q2 8th, Smart Experience Q3 6th, Convenience Q4 8th, Durability Q5 4th, Value for Money Q6 2nd), with attribute coverage of 6/6 (Ranking). However, it was not recommended in any of the 6 Recommendation questions, with attribute coverage of 0/6 (Recommendation). This is the brand with the largest gap between Ranking coverage and Recommendation coverage among all brands.
Aqara appears in 5 of the 6 Ranking questions across the attributes (Security Q1 4th, Reliability Q2 5th, Convenience Q4 6th, Durability Q5 6th, Value for Money Q6 4th), with attribute coverage of 5/6 (Ranking). In the Recommendation questions, it appears only in Smart Experience Q9 at 2nd place, with attribute coverage of 1/6 (Recommendation).

In the Recommendation questions, it appears in Reliability Q8 (4th), Smart Experience Q9 (5th), and Durability Q11 (4th), with attribute coverage of 3/6 (Recommendation). Kwikset did not enter the Top 3 in any attribute.
Brand performance differences across attributes
Among the safety and durability attributes, Schlage ranked Top-1 in both, and was also recommended in Recommendation (safety as the top choice). These two attributes are the areas where Schlage performs most strongly.
Among the smart experience and convenience attributes, August ranked Top-1 in both, and was also the top recommendation in Recommendation for the convenience attribute, but in the smart experience attribute, the top recommendation in Recommendation was replaced by Yale.
The value-for-money attribute is the most dispersed in brand distribution, with brands such as Eufy, Ultraloq, Wyze, and Aqara—whose rankings are relatively low in other attributes—entering the Top-3, while Schlage and Yale both did not make the Top-3.
Brands with attribute advantages
Schlage shows a clear advantage in the two attributes of safety and durability, ranking Top-1 in both and receiving the top recommendation in safety Recommendation.
August shows a clear advantage in the convenience attribute, ranking Top-1/top recommendation in both Ranking and Recommendation, and also receiving the top recommendation in the Recommendation for reliability and durability.
Eufy shows a clear advantage in the value-for-money attribute, ranking Top-1/top recommendation in both Ranking and Recommendation, but ranking relatively low in all other attributes (8th in safety, 8th in durability).
Ultraloq appears in the Ranking for all 6 attributes, but does not achieve Top-1 in any attribute, and does not appear in any of the 6 Recommendation questions, showing a characteristic of "widely mentioned but with no attribute advantage."
14. Stability and confidence
This audit sampling round consisted of 1 round, with a total of 12 AI responses obtained.
According to Rule 3: sampling rounds < 2, stability cannot be verified (insufficient sampling).
All conclusions in this report are based on single-round sampling data, and it is not possible to determine the consistency of AI outputs across different times and session conditions. As a non-deterministic model, ChatGPT may produce different brand rankings and recommendation results for the same question in different sessions. To verify stability, at least 2 rounds of independent sampling are required, and fluctuations in brand frequency and ranking positions should be compared.
15. Global Aggregation
The following is the global brand appearance frequency ranking based on BMF (descending):
1. Schlage — BMF: 12/12
2. Yale — BMF: 12/12
3. August — BMF: 10/12
4. Aqara — BMF: 8/12
5. Eufy — BMF: 7/12
6. Ultraloq — BMF: 7/12
7. Kwikset — BMF: 6/12
8. Level — BMF: 6/12
9. Lockly — BMF: 5/12
10. Wyze — BMF: 3/12
11. Nuki — BMF: 2/12
12. TP-Link Tapo — BMF: 1/12
This aggregation is frequency-based and does not represent a unified ranking output by the AI.
Schlage and Yale are tied for the highest BMF, both appearing in all 12 responses. August follows closely at 10/12, forming a clear top cluster of three brands. Aqara ranks fourth with 8/12, showing some distance from the top cluster. Eufy and Ultraloq are tied for fifth in BMF (7/12), but there is a significant difference in Top-1 and Recommendation Rate (Eufy: Top-1=2/12, Recommendation Rate=1/6; Ultraloq: Top-1=0/12, Recommendation Rate=0/6). Nuki and TP-Link Tapo have very low BMF values (2/12 and 1/12), indicating brands that appear infrequently.
16. Key Findings
Finding 1: Highly concentrated top brands
Schlage (BMF=12/12) and Yale (BMF=12/12) both appeared in all 12 responses, while August (BMF=10/12) appeared in 10 responses. Together, these three brands form the core brand cluster in the AI output, appearing in all ranking questions across the six attributes.Finding 2: Schlage achieved a 100% Top-1 share in the security and durability attributes
In the ranking questions for the security (Q1) and durability (Q5) attributes, Schlage received Top-1 in both cases (2/2, 100%). In the security recommendation question (Q7), Schlage received the sole top recommendation, with the original text reading: "For a pure security-first buyer, I’d choose Schlage over every other mainstream smart lock brand today."Finding 3: August performed better in recommendations than in Top-1 rankings
August received the top recommendation 3 times across all 6 recommendation questions (reliability Q8, convenience Q10, durability Q11), for a top recommendation rate of 3/6 (50%). However, in the corresponding ranking questions, August received Top-1 only in convenience (Q4) and smart experience (Q3), ranking 4th in reliability (Q2) and 3rd in durability (Q5), and did not receive Top-1.Finding 4: Schlage shows a Ranking-Recommendation gap in reliability and durability
In the reliability attribute, Schlage ranked Top-1 in Ranking (Q2), but ranked second in Recommendation (Q8), with the first choice taken by August, Gap=+100% (Ranking Top-1 rate 100% vs. Recommendation first-choice rate 0%). In the durability attribute, the same pattern repeated, Gap=+100%.Finding 5: Ultraloq appears widely in Ranking but is completely absent in Recommendation
Ultraloq appeared in the Ranking questions for all 6 attributes (BMF=7/12, attribute coverage=6/6), but did not appear in any of the 6 Recommendation questions (Recommendation Rate=0/6). This is the brand with the largest gap between Ranking coverage and Recommendation coverage among the 12 brands.Finding 6: The cost-effectiveness attribute shows a brand distribution completely different from other attributes
In the cost-effectiveness attribute's Ranking (Q6) and Recommendation (Q12), the Top-1 brand was Eufy in both cases, and neither Schlage nor Yale made the Top-3 (in Q6, Schlage ranked 6th and Yale ranked 5th; in Q12, Schlage ranked 6th and Yale ranked 5th). This is the only one of the 6 attributes where neither Schlage nor Yale entered the Top-3. Brands that ranked lower in other attributes, such as Eufy (Q6 Top-1), Wyze (Q6 3rd), and TP-Link Tapo (Q12 3rd), appeared prominently in this attribute.
17. Limitations
Sample size limitations
This audit obtained a total of 12 AI responses, covering 6 attributes and 12 questions. The sample size is relatively small; each attribute has only 2 responses (1 Ranking + 1 Recommendation), so it cannot represent the full possible range of AI outputs for that attribute.Single-round Sampling Issue
This audit conducted only one round of sampling, so stability could not be verified (insufficient sampling). As a non-deterministic model, ChatGPT may produce different results for the same question across different sessions. A single round of data is insufficient to determine the stability of brand frequency and ranking positions.Model Randomness
ChatGPT’s output is random; even with the same prompt and in the same environment, responses may differ across sessions. All conclusions in this report reflect only the specific output of this sampling and do not represent the model’s deterministic behavior.Possible Ambiguity in Brand Classification
Some brand names appeared in AI responses as model names or sub-brand names (e.g., "Schlage Encode Plus", "Yale Assure Lock 2"), and normalization may have caused some fine-grained information to be lost. As a European brand, Nuki may be perceived by AI in the North American market differently from its actual market position.Methodological Limitations
The attribute selection (security, reliability, smart experience, convenience, durability, value for money) was predetermined by the auditor; different attribute selections may lead to different brand distribution results. The wording of the question has a direct impact on AI output, and subtle differences in wording may lead to different brand ranking results. This audit used an overt query (Overt Query), and AI may exhibit specific output patterns for explicit ranking-related questions, which may differ from outputs in implicit query scenarios.
