1. Check whether the circlip of the handle is broken. 2. Check whether the square pin inside is falling off. If the lock body can be opened and closed normally from the inside, then there is no problem.
Explain that your handle and your lock body may not be in touch
There is a difference between double-active and double-fast, double-active means that the door can be opened by pressing the handle inside and outside the door without anti-locking, and the door can be locked by lifting the handle inside and outside the door.
If it's not different, it's like a normal door handle.
It's easy to have problems, and when you're outside, the handle is also a lock door, but you can only use a key to open the door, and if you don't bring the key, you'll be locked outside, and the life of the lock is not as long as ordinary.
