We replaced an unreliable mortise cylinder on a store entrance in Cliffside Park, Bergen County, NJ. The owner had been struggling to unlock the door each morning because the key would not turn smoothly, sometimes requiring several attempts.
Concerned that the lock could fail and prevent employees from opening or securing the store, the owner contacted American Star Locksmith to inspect the entrance.

Replacing the Store Entrance Cylinder
Our locksmith inspected the existing mortise cylinder, lock body, and surrounding door hardware. After we evaluated the problem and discussed the options, the customer chose to replace the unreliable cylinder.
We removed the old cylinder and checked the cylinder opening, existing lock body, and hardware alignment before fitting the replacement.
The new silver-finish mortise cylinder was positioned and secured in the commercial lock body. The work focused on replacing the keyed component while retaining the existing lock body and entrance hardware.
The photos show the exterior key cylinder beneath the storefront pull handle and the thumb-turn hardware on the interior side of the door.
Testing the New Cylinder and Keys
After installation, we tested the new keys from outside to confirm that the cylinder turned smoothly. We also checked that the lock engaged and released correctly without sticking or excessive resistance.
The store owner could once again lock and unlock the entrance smoothly, resolving the recurring difficulty at opening time.
Our mortise cylinder services include assessing the cylinder together with the existing lock and door hardware. This helps determine which component needs attention before recommending repair or replacement.
