Keyless Electronic ID Card Door Lock MID300 Right Hand




This lock is a stand alone ID card access door lock. It is designed for all kinds of doors including residential homes, apartments, warehouses, airports, and office buildings. It fits most predrilled 2-3/8" or 2-3/4" backset knob-lock doors. Programming cards is very easy and takes only a few minutes. Programming cards is done by lock, no extra equipment needed. One card can be programmed to many locks. A card also can be deleted from locks. One lock can be programmed for up to 500 cards. Works with most 125khz frequency RFID cards (cards sold seperately).

The lock will mechanically automatically lock itself when the door is closed. From outside, you can turn the handle but the door will be locked.
