Today I replaced the mechanism on the UPVS door because the door was jammed and would not open. I opened the door. It was necessary to replace the mechanism and adjust the door. The client tried very hard to lift the door handle up and broke the mechanism. Now the door opens and closes like new. I want to tell everyone that if you cannot lock your door with a key, there is no need to forcefully lift the door handle up and forcefully turn the key. The mechanism can break and the key can also break and remain in the door lock. If you still have such a problem, which very often happens, contact us and we will help you. You will save your door mechanism and your money.
