FAQ
Sliding doors can be fitted with keyed patio locks, foot bolts, Charlie bars, loop locks, pin locks, and smart electronic devices. Most South Florida homeowners benefit from combining the primary latch with at least one secondary device. For coastal properties, always choose stainless steel or marine-grade hardware. For more info, read our blog: What Kind of Lock Can I Put on a Sliding Door?
Burglars most commonly enter through sliding doors by defeating the factory latch with a screwdriver or shim, lifting the door off the track when the anti-lift pin is missing, or exploiting a corroded lock. Adding a secondary lock and checking the anti-lift mechanism eliminates the two most common vulnerabilities. For more info, read our blog: How Do Burglars Break In Through Sliding Doors?
Burglar proofing a sliding glass door combines a secondary mechanical lock (Charlie bar or foot bolt), a verified anti-lift device, marine-grade lock hardware, and exterior lighting. In South Florida, impact glass eliminates the glass-breaking entry method entirely. For more info, read our blog: How Do You Burglar Proof a Sliding Glass Door?
The most common sliding door lock problems are a latch that won't engage, a handle that turns but doesn't lock, a lock that's stiff or stuck, corrosion damage to the mechanism, and a door that's misaligned so the latch can't reach the strike plate. Most are caused by wear, salt air corrosion, or the door dropping off its correct height. For more info, read our blog: What Are the Common Problems With Sliding Door Locks?
Law enforcement crime prevention programs consistently recommend a layered approach for sliding doors: a secondary mechanical lock (Charlie bar or foot bolt), a verified anti-lift device, a keyed primary lock, and exterior lighting. The secondary lock is the single highest-priority recommendation across all agencies. For more info, read our blog: What Door Locks Do Police Recommend?
Choosing the right sliding door lock depends on your door type, proximity to saltwater, how often the door is used, and whether the property is seasonally vacant. The correct baseline for any South Florida sliding door is a functioning primary latch plus at least one secondary mechanical lock. Material grade matters as much as lock type in coastal environments. For more info, read our blog: How Do I Choose the Right Sliding Door Lock?
The seven main types of sliding door locks are: the factory latch, keyed patio deadbolt, foot bolt, Charlie bar, loop lock (anti-lift device), pin lock, and smart electronic locks. No single type addresses all vulnerabilities — most South Florida homeowners benefit from combining two or three. For more info, read our blog: What Are the Types of Sliding Locks?
Yes — you can put a new lock on a sliding door without replacing the door itself. The existing handle and latch assembly can be replaced with a keyed patio lock, and secondary devices like Charlie bars and foot bolts can be added to any existing door. Most lock upgrades are same-day jobs. For more info, read our blog: Can You Put a New Lock on a Sliding Door?
Yes — replacing a sliding door lock yourself is a realistic DIY job for most homeowners. A primary latch swap requires only a screwdriver and the correct replacement part. Secondary locks like Charlie bars and foot bolts require a drill. The main risk is sourcing the wrong part — confirm fitment before purchasing.

The fastest no-cost fix is a cut-down dowel or broom handle in the track channel — prevents sliding with no tools. A pin lock drilled through the overlapping frames adds stronger resistance for under $10 in 10 minutes. Both are temporary; schedule permanent lock replacement as soon as possible.

Replacing a lock on a patio door typically costs $75 to $250 in South Florida, depending on the lock type, hardware grade, and whether secondary locks are added at the same time.
