Buy the Alarm Lock DL5275 Electronic Double Sided Digital Locks with Regal Curved Lever from The locks come with a keypad in which users enter a pin to unlock and open the door. There are two models available in the DL5275 series, the DL5275 Standard Key Override with Regal Curved Lever and the DL5275IC Interchangeable Core with Regal Curved Lever.

The Alarm Lock DL5275 and DL5275IC sold under the Trilogy brand, are grade 1, heavy duty, access control locks.

Direction wise access can be given to users (i.e. users can be given access for going in, coming out, or for both sides), and programming codes can be done on one side of the lock, saving time and labor which would have been required to program the other side.

The locks come with an elegantly designed Regal Curved Lever. Choose from a standard preparation (DL5275) or an interchangeable core (DL5275IC) model, which best suits your needs.
