Sliding Door Smart Lock: The Ultimate Buying Guide
Sliding doors and narrow aluminum frames need a very different smart lock than a standard wooden front door. Regular locks are too thick, too wide or not weatherproof enough. The SK-X8 Tuya/TTLock sliding door lock is designed specifically for this use case.
Why Sliding Doors Need Special Locks
Sliding doors, broken bridge aluminum doors and narrow-frame glass doors have limited space. A standard smart lock is too thick to fit and may not withstand outdoor weather. You need a slim, waterproof lock designed for narrow profiles.
IP65 Waterproof and Slim 34mm Design
The SK-X8 is IP65 waterproof — rain and dust will not damage it. At only 34mm thick, it fits narrow aluminum and sliding door frames perfectly. The 335mm length gives enough room for a keypad, fingerprint sensor and electronic doorbell.
Six Unlock Methods
- Semiconductor fingerprint (fast and reliable)
- IC card / swipe card
- Password keypad (with virtual password)
- Mechanical key backup
- Tuya or TTLock App remote unlock
- Temporary password for guests
