How do I prepare my door for a new lockset?

Door Prep

Emtek locks fit into a standard American-style tubular door prep. If you are replacing existingDoor Prep locks then your door preps will most likely be correct for Emtek locks. Just determine the backset and you're ready to order. If you're installing locks in new doors that do not have a door prep you can follow the instructions below.

PASSAGE, PRIVACY, KEY-IN-KNOB OR LEVER, AND DEADBOLT LOCKS fit into the door prep shown above. Bore a 2-1/8" hole through the door. The center of this hole should be located 2-3/8" or 2-3/4" back from thecenterline hole edge of the door (this is the backset dimension). Bore a 1" hole in the edge of the door located on the centerline of the 2-1/8" hole. The latch will fit into the 1" hole. Chisel out a 1" by 2-1/4" rectangle on the edge of the door, 1/8" deep. The latch faceplate will sit in this recession.

KEYED LOCKS WITH SIDEPLATES require two sets of holes with a center-to-center distance of 3-5/8" between the two sets of holes.
