  The backset describes the length of the latch itself. To determine this, start at the center of the borehole drilled in the door and measure to the edge of the door.

Most interior doors measure 1 3/8” thick, while most exterior doors measure 1 3/4” thick.

Choose "Keyed Alike" to use the same key on mulitple locks or "Keyed Differently" to ensure that multiple locks will require different keys. If you require us to key a lock the same as an existing key, please enter the key code in the custom keying box.

Please contact customer service for assitance with master keying or keying multiple manufacturers the same.
