Push Button Door Locks are activated by pressing a series of letters, numbers and special characters. There are two main types - mechanical and electronic. Both types can have a key override in case the code is forgotten.
The Mechanical Push Button Lock is the simplest as it unlocks the door with the action of the lock itself. It is also the cheapest to install, however you will have to change the code manually on each lock when necessary. Digital Push Button Lock systems can range from a standalone system to a multi-site IP based (networked) system. Standalone means each separate system will need to be updated individually. IP (Networked) Push Button Locks can be controlled centrally therefore making mass updates quicker and more accurate.
