Lesson 9: Storefront Locks - Part 4

Servicing Storefront Locks

Servicing store front locks means one of two things, removing the Mortise cylinder or removing the Adams Rite. Typically you will remove the mortise cylinder when you are rekeying the locks or upgrading the Mortise Cylinder. Mortise cylinder and Adams Rites are designed to have many grades of Mortise cylinder. Typically you would only remove the Adam’s Rite when you are repairing or replacing it.

Removing the Cylinder:

If you wish to rekey or replace the Mortise cylinder you will need to remove it from the Adams Rite.

      1. To remove the cylinder, first unscrew the faceplate screws and remove the faceplate. This should expose the set screws.
      2. Loosen the set screws until the cylinder can be freely spun. Note: Do not remove the set pins, loosen them until the cylinder spins and then leave them in the Adams Rite.
      3. Now unthread the Cylinder until it comes out of the Adams Rite. If you are rekeying the cylinder, remove the cam by unscrewing the cam screws and then rekey the lock as normal.
      4. To reassemble the lock, thread the cylinder into the Adams Rite until it is snug. Note: this lock works best if it sits comfortably. Being either too tight or to loose will cause problems. Align the keyway so that it is vertically aligned with the door.
      5. Tighten the set pins. Check to make sure the set pins are preventing the mortise cylinder from rotating. Now check the keys to make sure the cam is engaging with the bolt.
      6. Reattach the faceplate.
  • Some storefronts have their mortise and Adams right located on the bottom of the doors. These doors need to be taken off there hinges before the locks can be serviced.

Replacing the Adams Rite:

If you wish to replace the Adams right you will need to remove the mortise cylinder before removing it from the door.

      1. To remove the cylinder, first unscrew the faceplate screws and remove the faceplate. This should expose the set screws.
      2. Loosen the set screws until the cylinder can be freely spun. Note: Do not remove the set pins, loosen them until the cylinder spins and then leave them in the Adams Rite.
      3. Now unthread the Cylinder until it comes out of the Adams Rite.
      4. Insert your finger into the mortise hold and grip the Adams Rite. This is to prevent the Adams Rite from falling inside the door as you remove the 2 retainer bolts. These bolts are at the top and bottom of the Adams Rite.
      5. Extract the Adams Rite.
      6. To reassemble the Adams Rite, insert the Adams Rite into the door. Note: make sure you hold onto the Adams Rite. This is a likely time that you could drop the device inside the door. Make sure you are holding onto the Adams Rite at all times.
      7. Thread the 2 retainer bolts. Leave them a little loose so that you will have more leeway when you thread the mortise locks back on.
      8. Thread the cylinder into the Adams Rite until it is snug. Note: this lock works best if it sits comfortably. Being either too tight or to loose will cause problems. Align the keyway so that it is vertically aligned with the door.
      9. Tighten the set pins. Check to make sure the set pins are preventing the mortise cylinder from rotating. Now check the keys to make sure the key is engaging with the bolt.
      10. Fully tighten the retainer bolts and reattach the faceplate.
