This lock is just like the Lockey 2230 Latchbolt Lock, except that it has lever handles and a passage mode function.
This lock has a Passage Function so it can remain in the unlocked position, if you prefer. This makes it ideal for an office environment where the door should remain unlocked during business hours, but locked after hours. For added security, you will need to know the code to use this function. Simply just enter the code followed by the Y on the keypad, this will enable or disable the Passage Function.
The latchbolt is set in the hole in the door where the deadbolt normally goes, so this lock installs and operates very much like a standard deadbolt lock. However, the latchbolt head also contains a burglar-proof plunger for added safety.
