What is the difference between a digital and a mechanical lock?
A mechanical lock employs a 3 number dial that is turned to the opening combination. If the combination needs to be changed it must be done by a qualified technician. The digital lock employs a push button dial that uses a series of numbers to open the lock and is powered by batteries. The combination can be changed by the user. Generally digital locks are easier to use, open quicker, and allow user combo changes.
