Magnetic Locks are locks that use magnets and electricity to secure the entry point. When a key or an access entry point is used, an electric current releases the magnet to open the door. Once the door is shut, the magnet locks automatically again.
Magnetic Locks are very convenient for large offices with many employees because they usually require a key card and an access control point instead of traditional keys. You can program a card for any employee and remove them from the list in the instance they no longer work in the office.
