Lock won't latch or catch
The handle moves but the door never truly locks. Usually a worn mortise lock, a bent latch hook, or a sagging panel that no longer lines up with the strike plate.

Why sliding door locks fail
Usually it's not just the lock
A sliding door lock only works when three things line up: the latch, the strike plate and the panel itself. When rollers wear out, the panel drops a few millimeters and the latch starts missing the strike — so the lock feels broken even when it isn't. That's why we always check panel height and alignment before quoting a lock replacement.
When the hardware really is worn — corroded cylinders, cracked handles, mortise locks that no longer throw — we replace it with parts matched to your door's brand and profile, most of which we carry on the truck.

Common lock problems we fix
If your sliding door won't lock, it's one of these
Broken or loose handle
Handles crack, pull loose from the panel, or spin without engaging. We replace the full handle set — interior and exterior — matched to your door's profile and finish.
Key lock stopped working
Exterior keyed cylinders corrode fast in South Florida humidity and salt air. We replace the cylinder or the full keyed handle set so the door locks from outside again.
Door can be lifted off the track
Many older sliders can be lifted straight off the rail from outside — a real security gap. An anti-lift kit plus a properly adjusted lock closes it.
Lock misaligned after roller work or settling
If the panel has dropped even a few millimeters, the latch misses the strike. We re-level the panel and adjust the strike so the lock engages with a clean click.
Want a second locking point
Foot bolts, security bars and child locks add a second layer beyond the standard latch — popular for ground-floor patios and families with small kids.
Beyond the standard latch
Make your sliding door actually secure
The factory latch on most sliding glass doors is the weakest lock in the house. While we're replacing or repairing your lock, we can add a second layer of security in the same visit:
- •Anti-lift kits — stop the panel being lifted off the track from outside, a common break-in method on ground-floor patios
- •Foot bolts — a second locking point at the bottom of the panel that works even if the main latch fails
- •Child locks — keep little ones from opening the door to the pool or patio on their own
- •Keyed exterior cylinders — lock and unlock the patio door from outside, not just from inside

South Florida sliding door repair FAQs
- How much does sliding door lock replacement cost?
- Far less than replacing the door. Most lock and handle jobs are a single-visit repair, and we quote a firm price on site before any work begins. The estimate itself is free.
- My sliding door lock won't catch — can it be repaired or does it need replacing?
- Often the lock itself is fine and the panel has sagged, throwing the latch out of alignment with the strike. We check panel height and alignment first; if the mortise lock or latch is worn or broken, we replace it with hardware matched to your exact door profile.
- Can you match my existing sliding door handle and lock?
- In most cases, yes. We carry the most common mortise locks, latch kits and handle sets for South Florida door brands on the truck, and we match finish and profile so the replacement looks right.
- Can you make my sliding glass door more secure?
- Yes. Along with a new lock we can add anti-lift kits that stop the panel being lifted off the track, foot bolts for a second locking point, and child locks for families — all in the same visit.
- Do you replace locks on impact sliding doors?
- Yes. Impact-rated sliders use heavier multi-point and mortise hardware, and we stock and source the correct replacements so the door keeps its rating and closes tight.
- How fast can you get to me?
- We run daily routes across Broward and Palm Beach counties, and most lock repairs finish in one visit. Call (754) 228-7654 for today's openings.
