Quick Answer: Standard hook lock replacement costs $150–$350 installed in Broward County. Multi-point security lock systems run $250–$550 installed. Most replacements are completed same-day. We carry locks for all major door brands.
When Should You Replace a Sliding Door Lock?
Lock replacement is recommended (rather than repair) in these situations:
- The lock mechanism has seized due to advanced corrosion and cannot be freed
- The lock body is cracked, broken, or deformed from a break-in attempt
- The existing lock is more than 10 years old and components are no longer available
- You want to upgrade from a basic hook lock to a multi-point security system
- You are moving into a home or condo and want fresh hardware you know the key history of
Lock Options We Install
- Standard hook lock replacement ($150–$250) — Drop-in replacement of the existing hook lock with an identical or compatible unit. Same security level, new components. Most installations take 30–45 minutes.
- Keyed hook lock ($200–$350) — A hook lock with a key cylinder for external locking without a separate deadbolt. Useful for primary-entry patio doors in Broward County condos and townhouses.
- Multi-point lock system ($250–$550) — A single handle operation simultaneously engages 3–5 locking points along the vertical stile of the door. Significantly stronger than a single hook. Recommended for homes in high-crime areas or after a break-in attempt. Requires routing the lock body into the door stile.
- Secondary foot bolt / floor lock ($80–$150) — An add-on security lock mounted at the base of the door panel. Drops a steel bolt into a hole in the track when engaged. Inexpensive and very effective as a secondary lock, particularly to prevent door lifting (prying from below).
Can Any Lock Replace an Existing Sliding Door Lock?
Not always. Sliding door locks use proprietary mounting patterns that vary by door manufacturer and model. PGT, CGI, and Andersen each use different screw hole patterns and hook geometries. We carry locks for all major brands and can identify the correct replacement for your specific door model. Avoid buying a replacement lock from a big-box store without knowing your door's manufacturer and model — many homeowners end up with a lock that doesn't fit.
