Mortise cylinders
Rekey or replace compatible cylinders with the correct length, cam, collar and keyway.
Rekey, repair and replace selected commercial storefront cylinders, hook bolts, deadlocks, paddles, thumb turns, strikes and related mechanical hardware.
Full door, edge, cylinder and strike photos are important because storefront parts are highly configuration-specific.
An aluminum storefront opening is not a residential deadbolt in a thinner door. Cylinder length, cam, backset, bolt projection and door alignment must match.
Rekey or replace compatible cylinders with the correct length, cam, collar and keyway.
Evaluate hook bolts, deadlocks, internal linkage, strike engagement and door/frame alignment.
Service selected narrow-stile lock bodies, bolts, latches, paddles and outside pulls.
Replace or correct inside thumb turns, outside cylinders and keying for authorized access.
Diagnose loose, broken or disconnected push/pull paddles and internal actuating hardware.
Evaluate the mechanical latch, cylinder, strike relationship and alignment; wiring and access-control programming are separate scopes.
The direction of pressure on a narrow-stile door can make a good cylinder feel like a failed lock.
| Symptom | Likely checks |
|---|---|
| Key turns only while pushing or pulling door | Door alignment, pivot/hinge condition, strike position and bolt pressure. |
| Key spins without operating lock | Cylinder cam, set screw, linkage, lock body and incorrect cylinder length. |
| Hook bolt will not extend or retract | Door position, internal lock wear, linkage, contamination and strike engagement. |
| Paddle moves but door remains locked | Paddle linkage, latch/lock body, dogging or access-control state. |
| Cylinder is loose or falling out | Retaining screw, cylinder threads, collar, length and lock-body damage. |
| Door does not close or latch | Closer, pivots, threshold, weather, strike, latch and frame alignment. |
A complete visual set can prevent ordering a cylinder or lock body that fits the keyway but not the door.
Excess force can twist keys, loosen cylinders or damage internal linkage. Relieve door pressure gently and stop when the key begins to bend.
A functioning lock can still be an access-control problem when old keys are unaccounted for.
Change the cylinder so the missing key no longer works, then issue new controlled copies.
Use a compatible cylinder and planned hierarchy so managers and staff receive appropriate access.
Restore operation without replacing every component when the lock body and door are serviceable.
Install the correct commercial narrow-stile hardware when repair is no longer reliable.
Yes, selected narrow-stile cylinders, hook bolts, deadbolts, paddles, thumb turns, strikes and related hardware can be evaluated and serviced.
Common causes include door sag, pressure against the bolt, worn cylinder or key, contaminated lock, bent linkage, damaged hook bolt or frame/strike misalignment.
Often. The cylinder format, cam, length, keyway and lock body must be compatible and serviceable.
Lock and mechanical hardware work can be handled within scope. Glass, aluminum fabrication, pivots, structural frame or full door replacement may require a storefront/glass contractor.
Often, using a compatible mortise or rim cylinder and correct cam. The existing keyway and system hierarchy must be checked.
Photos of the lock, door edge, strike, panic device or closer help identify the correct scope and parts. Include billing or vendor requirements at the start.
