Why does my door always open from the outside?
Prerequisites:
1. Make sure the smart door lock is powered up using fresh batteries. If it doesn't power up, Why is my Smart Door Lock not powering up? article.
2. Make sure the lock is configured (see this article to configure the lock).
There are a few different reasons why a door can open from the outside after it has been locked and deadbolted.
- It could be an installation error (Not applicable to SDL-H1). If you have a right swing door and the lock has been installed as a left swing door the door will open from the outside every time. The same is if you have a left swing door and the lock has been installed as a right swing door. Check sections 3 and 4 of the Installation Guide for the direction settings. These are some common Installation and User Guide links.
Smart Medium - Fingerprint and Keyless Entry Mortise Lock (SDL-H2)
Slim - Fingerprint and Keyless Entry Smart Mortise Lock [43mm wide] (SDL-S1)
Slim - Fingerprint and Keyless Entry Smart Mortise Lock [38mm wide] (SDL-S2)
Super Slim - Fingerprint and Keyless Entry Smart Mortise Lock [35mm wide] (SDL-SS1) - It could be that you have turned off the auto-lock. If auto-lock is off you need to lock the door manually by pressing and holding the # key or by pressing and holding the large padlock icon on the app (see this article for more information).
- It could be that it is in passage mode. To lock the door during passage mode you need to lock the door manually by pressing and holding the # key or by pressing and holding the large padlock icon on the app (see this article for more details).
- Check the lock alignment (see this article for more details).
- If the spindle is too long for your door thickness it could create too much friction resulting the spindle not to move freely.
To check if the spindle is too long for your door thickness, test the lock with the just the back panel off the door. Also, check the parts list in the User Manual to see which spindle is suitable for your door thickness. You can either select a smaller spindle size (if possible) or trim the spindle using a grinder (Do this with caution and do not over-shorten the spindle). Sometimes new locks come in the mechanically unlock state from the factory. Lock the door with the mechanical key first (If you can pull the key out of the key hole, it means you have locked it correctly). Now unlock with the key, then lock electronically by pressing on the # key on the keypad or by using the TTLock app.
