I also encountered it, how did I solve it in the end?
It can only be called unlocking, and the middle section of the lock cylinder of all anti-theft doors is shared, and the key is inserted inside, and the outside cannot be opened.
That is, the anti-lock is broken, the lock can't be locked, it is recommended that you don't try to lock it now, in case you can't open it inside your anti-lock. Just use the key lock for two laps, it's safer. You can't call outside without a key. Don't worry, wait until it's repaired before re-locking.
Depending on the situation, if the key does not rotate, poke it in like a needle, and try a few more times. The rain can be opened with another key, if it is rotated, then congratulations on your win, please open the handle, after all, the door is worth more than the lock
You mean change the lock cylinder. I just changed it a while ago, and it's better, and the anti-theft performance is better than 100. There are also cheap ones. I didn't use the installation master, I installed it myself. It's simple. Door-to-door payment should be added separately.
