Door Lock Repair & Replacement in Miami, FL
A door lock that sticks, won't turn, won't engage, or has been damaged is a direct security threat to your home. In Miami's salt-air and high-humidity environment, lock mechanisms corrode and wear out faster than in most other cities — and a failed lock needs to be addressed the same day it's discovered.
At Window Door Group, we repair and replace all types of door locks across Miami-Dade County — including deadbolts, knob locks, lever sets, mortise locks, multi-point locking systems, and smart locks. Most repairs are completed the same day with replacement hardware carried in our service vans.
We work on all door types — wood, fiberglass, steel, and aluminum — and serve homeowners and businesses across Miami, Kendall, Cutler Bay, Palmetto Bay, Homestead, and Coral Gables.

Lock problems in Miami escalate quickly. Don't wait until you're locked out or your home is left unsecured to call for help.
-
Key Is Hard to Turn or Won't EngageStiff or stubborn locks are often caused by internal corrosion or worn cylinders — very common in Miami's salt air. This is an early warning sign that will only get worse over time.
-
Deadbolt Doesn't Extend or Retract SmoothlyA sticky or partially-engaging deadbolt means the bolt isn't fully securing your door. Your home is compromised even when you think it's locked.
-
Lock Handle or Knob Wobbles or SpinsA loose lock handle indicates worn or missing internal components. Left unaddressed, this progresses to the handle spinning freely — making the lock completely inoperable.
