What Is a Mortise Lock?
A mortise lock is a lock that is set into a pocket — or “mortise” — cut into the edge of a door, rather than sitting on its surface. This recessed design makes mortise locks significantly stronger and more secure than standard cylindrical or knob locks, because the locking mechanism is deeply embedded within the door itself, offering far greater resistance to forced entry.
Mortise locks are commonly found on commercial doors, older residential properties, storefronts, office buildings, hotels, and apartment buildings. They typically combine a latch bolt and a deadbolt into a single unit, and are operated by a key from the outside and a thumbturn or lever from the inside.
Our Mortise Lock Services
Keymex provides a full range of mortise lock services for all property types:
Mortise Lock Repair
Is your mortise lock stiff, sticking, jamming, or simply not working as it should? Our technicians diagnose and repair all common mortise lock issues - worn internal mechanisms, broken springs, damaged cylinders, misaligned components, and more - getting your lock working smoothly again without unnecessary replacement.
Mortise Lock Replacement
When a mortise lock is beyond repair or too outdated to serve your security needs, we replace it with a high-quality new unit. We bring a full inventory of commercial and residential mortise locks so the job gets done in a single visit.
Mortise Lock Installation
Adding a mortise lock to a door that doesn't already have one? Our technicians handle the full installation process - cutting the mortise pocket, fitting the lock body, and installing the cylinder, handles, and strike plate - all to professional standards.
Mortise Lock Rekeying
Need to restrict access without replacing the entire lock? We rekey the mortise cylinder so existing keys no longer work, providing you with fresh new keys and full control over who can access your property.
Mortise Cylinder Replacement
Sometimes only the cylinder needs replacing — if it has been damaged, picked, drilled, or worn down. We replace mortise cylinders quickly and cost-effectively, often without disturbing the rest of the lock body.
High-Security Mortise Lock Upgrades
We upgrade older or standard mortise locks to high-security models that offer enhanced resistance to picking, bumping, drilling, and forced entry - ideal for businesses and properties that require a higher level of protection.
Emergency Mortise Lock Service
Locked out due to a failed mortise lock? We respond fast across San Antonio to get you back inside, then repair or replace the lock on the spot if needed.

- The lock is stiff, sticky, or difficult to turn
- The key turns but the door won’t open or lock fully
- The latch or deadbolt doesn’t extend or retract properly
- The lock has visible damage, corrosion, or wear

- The lock was involved in a break-in attempt
- You’ve lost keys and need to restrict access
- The lock is old and no longer meets your security needs
If you’re experiencing any of these issues, don’t ignore them – a failing mortise lock is a security vulnerability. Call Keymex and we’ll have it sorted quickly.

Mortise Lock vs. Standard Lock - What's the Difference?
Many customers ask why they should choose a mortise lock over a standard cylindrical lock. The key differences come down to strength, durability, and versatility. A mortise lock is set deep into the door, making it much harder to kick in or force open. Its internal mechanism is more robust, built to handle heavy daily use, and it combines multiple locking functions – latch, deadbolt, and sometimes privacy – into a single integrated unit. For any door that sees heavy traffic or requires a higher level of security, a mortise lock is the stronger choice.
Additional On-Site Services
While on-site for your mortise lock service, our technicians can also assist with:
Door Hardware Inspection
We inspect handles, levers, strike plates, and door frames to ensure everything works together properly and isn’t contributing to the lock issue.
Strike Plate Reinforcement
A weak strike plate can undermine even the strongest mortise lock. We install heavy-duty strike plates to reinforce the door frame against forced entry.
Commercial Lock Repair & Replacement
Beyond mortise locks, we service all types of commercial-grade hardware – deadbolts, panic bars, electric strikes, magnetic locks, and more.
Access Control Integration
For businesses looking to move beyond traditional keys, we install keypad, card reader, and smart access control systems that can work alongside or replace existing mortise lock hardware.
