Commercial locks take significantly more abuse than residential hardware — higher traffic, rougher use, and extreme DFW temperature swings that cause metal expansion and door frame shifting. When a commercial lock fails, it's not just inconvenient — it's a security risk and a potential code violation. MyKey's commercial repair team diagnoses and fixes lock problems on the first visit in most cases.
Common Commercial Lock Repairs
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.
Commercial Lock Installation
New lock installation for commercial doors requires more than just swapping hardware. Proper commercial installation includes: verifying door prep (the mortise pocket or bored hole matches the new lock), checking fire rating compatibility (fire-rated doors require fire-listed hardware), ensuring ADA compliance (lever handles, not knobs, and proper mounting height), adjusting the door closer for the new hardware, and testing all functions (locking, unlocking, latching, deadbolting, and panic function if applicable). MyKey installs commercial locks from all major manufacturers with workmanship guaranteed.

Commercial Lock FAQ
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.
