Treasure Coast Locksmith provides garage door lock installation services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Garage door lock installation covers three door types: side entry service doors (most common), overhead rolling garage doors (T-handle locks), and interior garage-to-house doors. Often the most neglected lock on a home. $95-$245 per lock depending on type and security level.
The garage is often the most vulnerable entry point on a Treasure Coast home. Most homeowners focus security attention on the front door and completely ignore the garage service door (the side entry), which typically has a builder-grade Grade 3 deadbolt on a hollow-core door with no reinforcement. Burglars know this - the garage side entry is a common target.
There are three separate lock categories for a typical garage. The side entry service door uses standard residential locks like any exterior door. The overhead rolling garage door uses T-handle locks or slide bolts for secondary security beyond the opener.
The interior garage-to-house door is technically an exterior door per code and requires specific hardware including self-closing features in some cases.
Treasure Coast Locksmith services all three garage door categories. We upgrade side entries to Grade 1 hardware, install secondary locks on overhead doors, and ensure garage-to-house doors meet Florida residential code.

Common garage door security problems
These are the garage security issues we see most often on Treasure Coast homes.
Typical garage door lock scenarios
- Tradition home with a Grade 3 builder deadbolt on the garage side entry - burglar's preferred entry point, upgrade to Grade 1.
- Fort Pierce home where the overhead garage door has no secondary lock and the opener can be bypassed with a universal remote.
- Vero Beach home with a hollow-core garage service door that should be solid core per Florida residential code.
- Stuart homeowner lost the garage service door key and needs replacement plus rekey of all exterior cylinders.
- Jensen Beach home where the interior garage-to-house door has no self-closer (required if the garage is attached).
- Port St. Lucie rental with a tenant complaint about the garage side door not locking properly - full repair and upgrade.
- Palm City new construction where the builder skipped the T-handle lock on the overhead door - secondary security added.
- Hutchinson Island home with corroded garage side entry hardware from coastal exposure - replace with marine-grade.
Garage door security considerations
Garage security works on multiple layers. The first layer is the overhead garage door itself. Modern garage door openers use rolling codes that are difficult to defeat by wireless attack, but older openers (pre-2010) often use fixed codes vulnerable to code-grabbing attacks.
If your opener is older, consider upgrading to a modern unit with rolling code technology.
The second layer is secondary overhead door hardware. A T-handle lock on the overhead door provides a keyed cylinder that physically locks the door in place regardless of the opener. Slide bolts on the door track do the same thing by blocking the wheel tracks.
These secondary locks are important when you're away on vacation - a burglar with a universal remote can't bypass a physical slide bolt.
The third layer is the garage service door (side entry). This is your primary exterior door for the garage and should have Grade 1 hardware, reinforced strike plate, and wraparound reinforcement if the door is fiberglass or hollow core. Most Treasure Coast homes ship with Grade 3 builder hardware on the garage service door - an immediate upgrade opportunity.
The fourth layer is the interior garage-to-house door. Per Florida residential building code, if the garage is attached to the house, this door is technically an exterior door and must meet exterior-door requirements including fire rating (20-minute minimum) and self-closing hardware in some cases. We install code-compliant hardware on these doors.

Garage security tips
- Upgrade garage service door to Grade 1 - it's often the weakest exterior point on the house.
- Install a T-handle lock or slide bolt on the overhead garage door for vacation security.
- Keep the garage side door keyed alike with your main house keys for convenience.
- Check that the interior garage-to-house door has a self-closing feature if required by code.
- Don't leave the overhead door opener remote in the car parked in the driveway - burglars target cars for garage remotes.
- Consider a smart lock on the garage side door for entry when arms are full with groceries or gear.

Garage door lock FAQs
Common questions about garage door locks and security.
How much does garage door lock installation cost?
Side entry service door Grade 1 deadbolt installation runs $145 to $245. Overhead door T-handle lock runs $95 to $155. Slide bolt installation runs $65 to $95.
Interior garage-to-house fire-rated deadbolt runs $165 to $265. Full garage security package (all three) runs $385 to $685.
Is the garage side door a common burglar target?
Yes. The side entry service door is often the most vulnerable point on a Treasure Coast home. Standard builder installs use Grade 3 hardware, hollow-core doors, and thin jamb framing.
Burglars know to check this door first on many homes. Upgrading to Grade 1 with reinforcement is a high-priority security investment.
Can you install a lock on the overhead garage door?
Yes. Overhead rolling garage doors can be secured with T-handle locks (a keyed cylinder mounted on the door) or slide bolts (that block the door track from opening). Both provide secondary security beyond the opener and are especially important when you're away on vacation.
Do I need a fire-rated door between the garage and house?
Per Florida residential code, yes, if the garage is attached to the house. The interior garage-to-house door must be a 20-minute fire-rated door with self-closing hardware. Most new construction meets this requirement, but older homes sometimes don't.
We can advise during an inspection.
Can you rekey my garage locks to match my house keys?
Yes. We rekey the garage service door and overhead door T-handle to match your main house key at no additional cost during installation or standard rekey service. Matched keying is convenient and doesn't affect security.
What's the difference between a T-handle lock and a slide bolt?
A T-handle lock is a keyed cylinder mounted on the overhead door face that you operate with a key. A slide bolt is a metal bolt that slides into a hole in the door track, physically preventing the door from opening. Both are secondary locks.
Slide bolts are simpler and cheaper; T-handles are convenient for occasional use.
Do you service garage door openers?
No, garage door openers are a separate contractor specialty (door opener companies). We service the lock hardware on the doors themselves, not the electric motor openers. For opener issues, call a garage door contractor.
For lock issues, call us.
Can you install a smart lock on the garage side door?
Yes. Schlage Encode and Yale Assure SL both work on standard residential garage side doors. They're especially useful for garage entries because you can unlock with your phone when your hands are full from gardening, beach gear, or groceries.
Installation is the same as any other exterior smart lock.
What if my garage service door is hollow-core?
Hollow-core doors are not code-compliant as exterior doors. If your garage service door is hollow-core, we recommend door replacement to a solid-core or steel door. For immediate security improvement without door replacement, we can add wraparound reinforcement plates to distribute force and install Grade 1 hardware.
Do I need to rekey the garage after a break-in?
Yes. Post-burglary rekey should include every exterior cylinder including all garage doors. The burglar may have touched or examined the garage lock during the break-in.
Comprehensive rekey resets key control across all exterior access points.
Can you add a keypad to my garage service door?
Yes. Schlage FE575 keypad deadbolt or full smart locks (Schlage Encode, Yale Assure) work on garage service doors. Keypad entry is convenient for garage entry because you don't need keys when working in the garage or yard.
Installation takes 30-60 minutes.
Does my HOA care about garage door locks?
HOAs usually don't restrict garage door lock changes because garage service doors are less visible than front doors. Some HOAs specify the overall exterior hardware finish, which may affect the T-handle lock if it's visible. We verify HOA requirements before installation if you're in a restricted community.
