We already have Exidor push opening system on all our exterior doors, and we have a key lock on the outside, we need to replace all the locks with a push button system. Does the thicknesses of the doors matter? Can we set them to be unlocked sometimes?

The CL1’s and CL2’s can be fitted to doors up to 60mm thick without modification.  The CL1 digital lock requires the code to be entered every time the door is opened from the outside.  The CL2 can operate that way, but can also be set to “passage function” which allows free access from the outside, as if it were just a door handle.  CL1 and CL2 are the same price.
