Digital Locks
Digital or electronic locks are keyless door locks and use a combination push button electronic lock for access control for both residential and commercial property in the UK. (Sometimes referred to as mechanical locks as they incorporate internal lever mechanisms.)
The low duty, medium duty and heavy duty digital locks vary in their level of security with low duty locks being used for internal security where a low level of access control deterrent is considered appropriate. The heavy duty digital locks are for external access points where a high level of security is required for high value premises.
