How to replaece the deadbolt lock?
There are different considerations for the mortise lock and the Euro cylinder locking device. The lock bodies of these locks can vary greatly in size. But no matter what type of lock you use, most things are suitable as long as you buy equipment from the most trusted door lock brand and have standard doors.
To replace the deadbolt lock with the same make and model, you don't have to worry about the measurement. However, if you make any changes to the type of bolt you are using, be sure to know the size of the pre-drilled hole on the door. This includes the diameter of the hole, the width of the door, and the distance of the through hole from the main lock hole (the length of the cross hole).
