Fast Locksmith 24/7 provides deadbolt installation across Houston, including adding deadbolts to doors that don't have one, replacing weak or worn ones, and reinforcing strikes so the bolt has something solid to hold onto. Planned installations are scheduled around your day.
A Typical Installation After a Neighbor's Break-In
Here's an example of how these calls often come in.
A couple in a subdivision in northwest Houston hears that a house two streets over was broken into through the door between the garage and the kitchen. The burglars got the garage open, then kicked the interior door. That night, the couple looks at their own garage entry door and realizes it has only a knob. No deadbolt. Their back door has one, but it wobbles.
They call us the next morning. The person who answers asks which doors they're concerned about, what's on each now, and whether the doors are wood, steel, or fiberglass. The garage entry is a steel-skinned door; the back door is wood. She explains what a deadbolt installation on the garage door involves, including boring the door and cutting the frame for a strike, and suggests the technician also check the back door's strike. She asks whether they'd like the new deadbolt keyed to their existing house key, and books an afternoon visit.
The technician arrives in uniform and introduces himself, and they show him their ID with the address. He starts with the garage entry door. He measures the right height and backset, uses a boring jig and a bit made for steel-skinned doors to drill the cylinder and edge holes cleanly, and chisels the mortise for the bolt's faceplate. On the frame, he cuts a strike pocket deep enough for the full one-inch throw and installs a heavy-duty strike fastened with long screws through the jamb into the wall studs. He rekeys the new deadbolt to their house key, then locks and unlocks it repeatedly to be sure it slides home without dragging.
On the back door, he finds the deadbolt itself is fine, but the strike is held by short screws in a cracked jamb. He replaces it with a reinforced strike plate that spreads across more of the frame and fastens it into the framing. The wobble is gone.
By the end of the afternoon, both doors lock with the same key, and the garage entry, the door that worried them, is now the strongest door in the house.
What Makes a Deadbolt Installation Strong
A Full One-Inch Throw
The bolt should extend a full inch into the frame. Shorter bolts are easier to pry out.
A Strike Anchored Into the Framing
The strike plate on the frame should be fastened with long screws that reach through the jamb into the studs behind it. Short screws only grip the trim, and that's where doors give way when kicked. On soft or damaged frames, a reinforcement plate spreads the force further.
Clean Alignment
The bolt should slide into the strike without rubbing. A bolt that drags wears out, binds in humid weather, and, on a smart lock, drains the battery.
The Right Grade
Residential deadbolts come in different security grades. Higher grades resist force and wear better on exterior doors.
A Door That Fits
If the door sags or rubs, it's adjusted before the deadbolt goes on.
Which Doors Need a Deadbolt
- Garage-to-house doors, often left with only a knob
- Back doors that open onto a yard out of sight from the street
- Garage side doors
- Doors on additions and converted spaces
- French doors, where the inactive leaf also needs solid top and bottom bolts
- Doors on rental properties, where Texas law requires keyed deadbolts on exterior doors
Sliding glass doors can't take a standard deadbolt, but a secondary pin lock and an anti-lift block do a similar job.
Single Cylinder or Double Cylinder?
A single-cylinder deadbolt has a key outside and a thumb turn inside.
A double-cylinder deadbolt needs a key on both sides. It's used on doors with glass near the lock, so nobody can break the glass and reach the thumb turn. The trade-off is that you need a key to get out, which can slow an exit in a fire. If you choose one, keep a key nearby and out of reach from outside. We'll help you decide door by door.
Deadbolts for Landlords
Texas law requires residential landlords to provide keyed deadbolts on exterior doors, along with other security devices, and to rekey them between tenants. We install deadbolts on rental properties, key each unit separately, and can set up a master key for the owner. See rekey service for turnovers, and lock installation for other required hardware.

Careful Work From Our Technicians
We send technicians in company uniforms who carry identification on every call. They measure before cutting, use boring jigs and bits suited to wood, steel, or fiberglass doors, protect your door finish and floors, and clean up afterward. They'll tell you honestly if a door is too thin or damaged to hold a deadbolt well, rather than install one that won't do its job.

Deadbolt Installation Across Houston
A deadbolt is only as good as the door and frame around it. Before fitting, we check that the door sits square, the hinges are tight and the strike has solid wood behind it. If any of those is off, we adjust it first.
Choose the grade that suits the door. Basic, standard and heavy-duty deadbolts differ in how well they resist force. We explain the options and fit what the frame can support.
Reinforce the strike. The screws holding it do most of the work in a forced entry. Long screws that reach the stud behind the frame make a real difference.
If you'd like, we can key the new bolt to match your existing handle set, so you carry one key rather than two.
Test the bolt before we go. It should throw and retract smoothly and seat fully in the strike without scraping.
Think about the other doors in the house. A strong bolt on the front door and a thin latch on the back door leaves the same weakness in a different place, and we're glad to look at both.
Houston's homes need deadbolts for different reasons. Older houses in the Heights, the East End, and the Third Ward often have soft frames that need reinforcing. Ranch homes in Spring Branch, Oak Forest, and Meyerland frequently have back and garage doors with only knobs. Townhomes inside the Loop have balcony and rooftop doors that were never upgraded. And newer suburban homes often have builder deadbolts held by short screws. For local details, see deadbolt installation in Spring Branch and Meyerland.
