Carbine manufactures deadbolt locks for commercial and residential exterior doors. Deadbolts have a large center latching mechanism that slides deep into the doorjamb for maximum security. Doors with deadbolts are harder for thieves to enter as they cannot kick in the doors as easily or slide a credit card between the latch and jam to gain access to a home or building. Replacing a sticking or broken deadbolt involves dismantling the defective lock to install a new one.

Things You'll Need

  • Small Phillips screwdriver
  • Flat screwdriver

Open the door containing the Carbine deadbolt.

Insert a small Phillips screwdriver into the top screw on the latch plate. Turn the screw counterclockwise to loosen and pull it straight out. The latch plate is the flat metal piece on the door facing that the deadbolt slides in and out of to lock and unlock the door.

Repeat this process for removal of the bottom screw on the latch plate. Pull the latch plate straight out of the door.

Insert a small Phillips screwdriver into the top screw on the lock cylinder on the inside of the door. Turn the screw counterclockwise to loosen and pull it straight out of the door. Repeat this process for the bottom screw. Repeat this process to remove both top and bottom screws from the outside of the door.

Place one hand on the outside and one on the inside portions of the deadbolt lock. Pull each half out from the center to remove them from the door.

Insert a flat screwdriver into the round hole in the lock assembly from either side of the door. Slide the screwdriver to the door edge to make the deadbolt protrude from the door face. Grasp the deadbolt lock and pull it straight out of the door face.

Tips & Warnings

  • A single-cylinder deadbolt has an exterior portion with a keyhole and the interior portion has a thumb lock. The thumb lock turns left and right to lock and unlock the door from the inside.
  • A double-cylinder deadbolt has a keyhole to lock and unlock on both the interior and exterior portions of the door.
