What the data shows
- 「ttlock passcode not working」在 Google Autocomplete 下返回 3 条真实建议：ttlock passcode not working；ttlock not unlocking；why is my passcode not working。
- TTLock 云端 API 文档原文写明：云端只保留半年内的操作记录。超过半年的开门记录在云端查不到，需要自建镜像。
- CERT 已公开 8 个未修复漏洞（CVE-2023-6960, 7003, 7004, 7005, 7006, 7007, 7009, 7017，VU#949046）。CERT 原文：There is no software solution for these vulnerabilities, only a potential work-around。
- TTLock Open Platform API 目录（user/lock/ekey/passcode/gateway/IC卡/指纹/人脸/记录/分组/固件/无线键盘/遥控/门磁/NB-IoT/二维码/WiFi锁/掌静脉/电表/水表）中不存在 doorbell、camera、video、intercom 任何端点——这是我们逐条核对完整目录得出的。
- 锁的 BLE 协议已被第三方逆向：service 0x1910、write 特征 fff2、notify 特征 fff4、包头 7f5a、CRC8-MAXIM。存在可本地控制的开源实现，云端仅在初次配对时联系一次。

We send the raw extract, not a brochure.
Why was this person denied?
Most access platforms tell you a door was refused, not why. Ours evaluates the rule chain and
names the reason — schedule window, group assignment, or suspended user.
