A:Install the TTlock app on your smartphone, then turn on your phone's Bluetooth and wake up the door lock's screen. Add the device within the TTlock app. Please refer to the video at the link:https://video.aliexpress-media.com/seller/play/5000430338359.mp4 Q2:Why is my door lock in the normally open mode or the handle won't turn? How do I change the setting? A:Reason:When the arrow direction behind the front panel is in the incorrect position, the door lock is in the normally open mode. When the arrow points upward or downward, the door lock handle cannot be turned. Correct setup: The arrow direction must be opposite to the handle direction. When facing the arrow, if your handle opens to the left, the arrow should point toward your left side. If your handle opens to the right, the arrow should point toward your right side.

A:Please refer to the manual or the installation video above the product details. Q6,Why can't the double hook lock body automatically close the lock, but the flat tongue lock body can automatically close the lock tongue? A:The double-hook lock body is of an anti-prying structure, and the hook can be driven to be withdrawn only by rotating a key or a handle after being popped out, and cannot be pressed back by an impact force; and the flat-tongue lock body is of an inclined plane design, and can be locked by automatically compressing a spring by hitting an inclined plane by a door frame when the door is closed. Q7,Why doesn't Lock when you directly press the icon Lock key on the keypad? What're the functions of the Lock and Unlock buttons on the keyboard? A:The Lock key functions as the “\*” key and serves two primary purposes: 1) to exit the current menu mode and return to the previous menu; and 2) to delete characters when setting a password in the menu. The Unlock key functions as the “#” key and is primarily used to confirm selections in the menu settings. ## Details - **Price:** 138.4 EUR - 160.58 EUR - **Vendor:** Tidesmit - **Tags:** smart door handles ## Variants | Variant | Price | Available | |---------|-------|-----------| | Black2885 / Left Handle | 157.35 EUR | In stock | | Black2885 / Right Handle | 157.18 EUR | In stock | | Black2885hook / Left Handle | 157.38 EUR | In stock | | Black2885hook / Right Handle | 156.15 EUR | In stock | | Black3585 / Left Handle | 157.37 EUR | In stock | | Black3585 / Right Handle | 157.17 EUR | In stock | | Black3585hook / Left Handle | 157.35 EUR | In stock | | Black3585hook / Right Handle | 157.70 EUR | In stock | | Black4585 / Left Handle | 159.36 EUR | In stock | | Black4585 / Right Handle | 138.81 EUR | In stock | | Black6085 / Left Handle | 141.92 EUR | In stock | | Black6085 / Right Handle | 156.96 EUR | In stock | | Silver6085 / Left Handle | 138.40 EUR | In stock | | Silver6085 / Right Handle | 141.97 EUR | In stock | | Silver4585 / Left Handle | 154.66 EUR | In stock | | Silver4585 / Right Handle | 160.09 EUR | In stock | | Silver3585hook / Left Handle | 156.93 EUR | In stock | | Silver3585hook / Right Handle | 157.07 EUR | In stock | | Silver3585 / Left Handle | 160.58 EUR | In stock | | Silver3585 / Right Handle | 160.25 EUR | In stock | | Silver2885hook / Left Handle | 156.01 EUR | In stock | | Silver2885hook / Right Handle | 156.68 EUR | In stock | | Silver2885 / Left Handle | 158.65 EUR | In stock | | Silver2885 / Right Handle | 158.57 EUR | In stock | ## Images - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header - Slim 2.8CM Waterproof Sliding Door Smart Lock Fingerprint Password IC Card Key Compatibility TTlock App & Alexa Biometric Header --- > Source: [Tidesmit](https://tidesmit.com/products/slim-2-8cm-waterproof-sliding-door-smart-lock-fingerprint-password-ic-card-key-compatibility-ttlock-app-alexa-biometric-header) > Updated: 2026-08-23
