Commercial Lock Repair & Installation DFW | MyKey

Mortise Lock Repair

Mortise locks are the workhorse of commercial door hardware. Common issues: stiff operation (internal components need lubrication or replacement), latch doesn't engage strike (door frame shift from building settlement or heat expansion), deadbolt won't throw fully (bent tailpiece or worn mechanism), and cylinder turns but lock doesn't operate (broken cam or clutch). We repair all major mortise lock brands: Schlage L-series, BEST, Corbin Russwin, Sargent, and Yale.

Cylindrical Lock Repair

Grade 1 and Grade 2 cylindrical locks (lever-handle and knob-type) are common on interior commercial doors. Repairs include: loose lever that wobbles (worn chassis), lock doesn't lock from inside (broken thumbturn mechanism), key works but latch doesn't retract (worn springs), and lock freezes in locked or unlocked position (failed clutch mechanism).

Electronic Lock Repair

Keypad, card reader, and fob-based locks need occasional service: dead battery causing lockout (we replace and reprogram), keypad buttons unresponsive (membrane replacement or unit replacement), programming errors (we reset and reprogram all codes), and solenoid failure (the electronic component that physically moves the bolt). We service electronic locks from Kaba, Alarm Lock, Trilogy, and Yale.

Q: Can you repair my commercial lock the same day?
A: Yes. We carry parts and replacement locks for common commercial brands. Most repairs are completed in one visit.

Q: Should I repair or replace my commercial lock?
A: If the lock is Grade 1 and the issue is internal (cylinder, springs, cam), repair is usually more cost-effective. If the lock is Grade 3 or visibly worn, replacement to Grade 1 is the better investment.

Q: Do you install locks on fire-rated doors?
A: Yes. We verify fire rating compatibility and install only fire-listed hardware on rated doors to maintain compliance.

Q: Can you match new locks to our existing key system?
A: Yes. We can key new locks to match your existing master key system or existing keys, maintaining operational consistency.
