Frequently Asked Questions
NO. The lock you have has nothing to do with the Addalock working.
If there is a space between the lock and the frame and the claws of the chrome metal handle fit into the strike plate then it will work.
The Addalock works only with the door strike on the frame and the door itself nothing to do with bolts and latches.
Note: if you both a latch and a dead bolt on your door use the addalock on the strike of the latch. That way you have the deadbolt still working and adding another lock. That id where the name came from Add-A- Lock
