Pushbutton Access Control – Mechanical Digital Door Locks

Mechanical digital locks are also known as pushbutton locks because this is what they are.  This page details the features, advantages and applications for this simple but effective form of access control.

What are Pushbutton Locks?

Pushbutton locks are robust, all-mechanical locks offering the dependability and convenience of key-less access control for a wide and continually expanding range of applications.  Each model operates with an entry code that is set when the lock is installed.  Codes can be reset in seconds, without removing the unit from the door.

Economically designed to provide effective and efficient access for authorised persons only – in offices, warehouses, on storerooms, locker rooms, cabinets, garages, caravans, sheds, gates, at home, almost anywhere – without the inconvenience of keys.

How do they work?

Pushbutton locks operate only when the correct buttons are pushed in the proper sequence and the turn knob is rotated.  A new combination is set when the lock is installed using as many of the 5 buttons as desired.  Buttons may be pressed individually or in unison.  Example: a combination of 2-3-4 pushed individually is NOT the same as 2 and 4 together, then 3.  Thousands of possible combinations make it virtually impossible to guess a code.
