Commercial lock installation

A technician removes the existing hardware, prepares the door and frame, and fits the new lock to the door’s handing and thickness. Mortise pockets, cylinders, and lever sets each follow different fitting steps.

Lock Specialists is a family-owned business that has served Simi Valley since 1973.

• The lock binds, sticks, or no longer throws the bolt fully.
• The cylinder turns loosely or the key feels rough.
• Pry marks or gouges show around the latch.
• Tenants or staff need a new keying arrangement.

• Worn mortise locks on high-traffic doors.
• Locks that no longer match a changed door thickness or backset.
• Cylinders with worn pins or a damaged keyway.
• Hardware that is hard to operate for people with limited grip strength.

The technician checks the door, frame, hinges, and existing hardware for fit and wear.

The technician confirms the door handing and backset, then protects the door finish during cutting and fitting.

The technician cuts the mortise pocket if needed, sets the new lock, and installs the cylinder and trim.

The technician tests the bolt, latch, and key cylinder through the full range of motion before leaving.

A mortise lock sits in a pocket cut into the door edge. Heavy-duty cases and bolts suit high-traffic doors. Cutting the pocket removes material, so thin or damaged doors may need reinforcement first.

Lever handles are easier to operate than knobs for many people. Lever trim pairs with mortise or cylinder locks, and the technician matches the trim to the lock body.

A mechanical pushbutton lock opens with a set combination of buttons and needs no batteries or wiring. Changing the combination follows the lock maker’s reset procedure, so plan a code change whenever staff turn over.

High-security cylinders resist picking, bumping, and key copying better than standard pin cylinders. Many use restricted keyways that need a key card or manufacturer authorization to duplicate.

Mortise locks: heavy-duty mortise cases, latches, and deadbolts.

Lever sets: interior and exterior lever trim.

Cylinders: standard, high-security, and interchangeable core cylinders.

Pushbutton locks: mechanical combination locks for storage rooms and back doors.

The lock matches the door’s thickness, backset, and handing.

Bolts and latches engage without binding.

A planned keying layout makes keys easier to track.

The technician checks every function before leaving.

• The cylinder works and only needs cleaning or lubrication.
• The mortise case is sound and the latch is worn or misaligned.
• The door still fits the existing hardware.

• The mortise pocket is damaged or the case is cracked.
• The lock no longer fits the door or its parts are no longer available.
• Repeated repairs add up to close to the cost of a new lock.

Heavy-duty mortise locks and high-security cylinders usually cost more than standard lever sets. Doors that need frame work add to the total. Lock Specialists gives an upfront quote before any work begins.

A lever or cylinder swap takes less time than a heavy-duty mortise install with door fitting. Multi-door projects run longer, and your quote states the expected schedule.

Tell the technician about any door that sticks or sags before the visit, because it changes the fitting steps.
