Deadbolt Installation in San Bernardino
Short answer: Most homes in San Bernardino should get a single-cylinder deadbolt: key outside, thumbturn inside, so anyone can get out fast during a fire. Double-cylinder models, keyed on both faces, can conflict with California egress rules on a home's main exit and belong only in narrow cases. Julian's Locksmith explains the trade-offs before installing anything. Call (951) 903-3193.

Before anyone drills into your San Bernardino door, there's a decision to make: should the inside get a thumbturn or a second keyhole? A single-cylinder deadbolt, key outside and thumbturn inside, lets anyone in the house get out instantly, which is what fire safety and California's egress rules favor for a home's main exit. A double-cylinder deadbolt needs a key on both sides. People ask for one when there's glass within arm's reach of the lock, yet it can trap family members during a fire if the key isn't where it should be. Julian's Locksmith walks you through both options, plus better fixes for that glass, before installing. Call (951) 903-3193.
A deadbolt is only as good as what it bolts into. In San Bernardino, plenty of doors have a decent deadbolt whose strike is held by half-inch screws in soft jamb wood, and one kick tears it out. A proper install uses a Grade 1 or 2 deadbolt with a one-inch throw, a reinforced strike box and three-inch screws that reach the wall stud. Choose single or double cylinder with care. A single-cylinder deadbolt has a thumbturn inside and suits most front doors. A double-cylinder needs a key on both sides, which can frustrate a thief reaching through broken glass beside the door but slows your own exit in a fire. California building rules generally want the main exit door to open from inside without a key, so a double cylinder is usually kept for doors that are not the main exit. Around the older homes near Seccombe Lake the thing to check is a brittle frame; in newer Verdemont houses it is usually a thin metal strike. The door from the garage into the house deserves a deadbolt too. Before we start we measure thickness and backset so the new bolt lines up.
What to know first in San Bernardino
Most houses around San Bernardino are wood-framed with stucco outside, and the door frame is a softwood or finger-jointed jamb set into a rough opening with shims filling the gap. That gap is why short strike screws do so little. A 3/4-inch screw holds only in the jamb itself, while a 3-inch screw crosses the shim space and anchors in the 2x4 trimmer stud. Driving that long screw too hard, though, draws the jamb toward the stud and can make the door rub, so we snug it rather than crank it and add a shim where the gap is wide. Door construction changes the job too. Solid wood and wood-edged fiberglass doors bore cleanly. Steel doors have a thin skin over foam and a lock block that must be located before drilling. Hollow-core doors, which turn up on some older garage-entry and side openings, have almost nothing to hold a deadbolt, and we'll tell you if a door isn't worth reinforcing. Afternoon sun on west-facing doors swells and bows panels, so we leave the bolt enough clearance to work through that daily movement.
Work included on a typical visit
- Grade 1 and high-security deadbolts. High-security deadbolts from Medeco, Mul-T-Lock and Schlage Primus add pick and drill resistance and, more important for many owners, restricted keys that can't be copied at a hardware kiosk. They make sense for homes with live-in help or frequent contractors, shared rentals, and anyone who has lost track of who holds a key.
- Keyed alike to your existing keys. Kwikset SmartKey deadbolts can be reset to another Kwikset key with a tool, which makes matching them quick. Pin-tumbler models from Schlage or Baldwin are re-pinned instead. For a house with two brands on different doors, we can change the odd cylinders so one key opens the front, back and garage-entry deadbolts.
- Fixing deadbolts that drag or won't fully throw. Afternoon sun on a dark steel door or seasonal swelling in a wood one can push the bolt out of line for part of the day. We test the lock at several points in the door's swing and set clearances so it works on a cool morning and in late-afternoon heat, rather than tuning it for one moment.
- French doors and double-door entries. French doors with glass close to the lock bring up the double-cylinder question again. Rather than default to a key inside, we often suggest laminated glass or security film with a single-cylinder deadbolt and solid flush bolts, which keeps the exit usable and still slows down anyone who breaks a pane.
- Rental, multi-unit and small-business deadbolts. Property managers in San Bernardino often need several units handled in one trip. We bring matching hardware, key each unit to its own key under a master if you use one, reinforce strikes on doors that have taken abuse, and leave the keys tagged. Incoming tenants get a deadbolt that works smoothly from day one.
How San Bernardino shapes the job
Older homes in San Bernardino often have solid wood doors that take a deadbolt well, but the hardware on them may date back decades: short-throw bolts, worn cylinders and strikes held by tiny screws. Some still rely on a lone knob or an original mortise lockset. We work with the door's existing holes where possible, avoid cutting into decorative panels, and fit a modern deadbolt with a full throw and a long-screw strike, matching period finishes where we can.
Downtown offices and older commercial buildings in San Bernardino often have heavy wood or hollow-metal doors, sometimes with original mortise locks or tired deadbolts. We install Grade 1 deadbolts or mortise deadlocks suited to those doors, check the egress requirements for each opening, and key the new hardware into existing master systems so building management keeps control over who can open what.
Foothill homes near San Bernardino face Santa Ana winds that push and rack doors, plus dust and sometimes ash in the air. Deadbolts here need clean alignment so wind pressure doesn't cause binding, and dry lubrication that won't gum up. If you evacuate during fire season, a properly thrown deadbolt with a reinforced strike helps keep the house secure while you're away, and keyed-alike doors simplify handing a key to a neighbor.
Common situations
Consider a duplex near Base Line Street where the entry doors have only knob locks, and the landlord wants each unit to meet the state's deadbolt rule for main entry doors. We would bore both doors for single-cylinder Grade 2 deadbolts, set reinforced strikes with long screws and key each unit separately. Each tenant gets keys for their own door, and the landlord keeps a record of how many were cut.
- For example, a landlord with a small fourplex gets a repair list after a tenant complaint, including worn deadbolts with stubby bolts that barely catch. We'd replace each unit's deadbolt with a full one-inch-throw model, key every unit differently, reinforce two strikes showing old pry marks, and hand over tagged keys with a simple key record. A job like that can usually be finished in one scheduled visit rather than four separate trips.
- Say you just closed on a newer tract home in the 92407 ZIP code. The builder installed light Grade 3 deadbolts with thin two-screw strikes. We'd swap the front, back and garage-entry doors to Grade 2 or Grade 1 deadbolts, key them alike, and replace the strike screws on every exterior door. Because the keys change at the same time, any construction or realtor copies still floating around stop working that day.
- Say you have patio French doors where the stationary door is held only by short flush bolts at the top and bottom. Push on the center and both doors flex inward together. We'd install longer flush bolts that seat deeper into the head jamb and threshold, then fit a deadbolt on the active door with a strike made for a door edge, so the pair resists force as one unit.
From your call to the finished job
- Tell us about the door. Call (951) 903-3193 and describe the door: wood, steel or fiberglass, whether it already has a deadbolt hole, and what hardware is on it now. A photo of the door edge and the inside face helps us bring the right jig, bits and deadbolt the first time.
- Assess the door, frame and options. On arrival we check for solid material around the lock area, look at the jamb for splits or old repairs, and watch how the door sits in its frame. Then we lay out the choices: single or double cylinder, Grade 1 or 2, and how much strike reinforcement the frame needs. You get a firm price before drilling.
- Prepare the door. Steel and fiberglass doors get extra care. We locate the internal lock block, use bits suited to metal or composite skins, and keep the foam core sealed. On wood, we score the veneer and bore from both faces so the hole stays crisp on the inside and outside of the door.
- Reinforce the strike and jamb. If you've chosen extra reinforcement, this is when the steel jamb strip, door-edge wrap and long hinge screws go in. Each piece is fitted around the existing trim and weatherstrip, so the door still closes softly and seals against dust and drafts in San Bernardino.
- Mount, key and align. Before the trim screws are tightened, we center the cylinder so the tailpiece isn't pinched, the most common cause of a stiff key on a new install. We rekey or reset the cylinder to match your other locks, then check that both the key and thumbturn throw the bolt all the way.
- Test and hand over. Before we leave, you try it yourself: key outside, thumbturn inside, door closed. We show you how to tell when the bolt is fully thrown and mention any related issues we noticed, like a worn knob latch or loose hinge, with no pressure to fix them today.
What affects the cost
- Door material, size and condition. Solid wood doors are the most straightforward. Steel doors need care with the skin and internal lock block, fiberglass needs sharp bits and patience, and thick custom doors may require extended tailpieces or special hardware. Each material affects both the time on site and the parts we bring.
- Keying and number of keys. Matching the new deadbolt to your existing house key is a small add-on. Rekeying every exterior lock to a new key at the same visit costs more but is often worth it after a move. Extra key copies, and especially restricted high-security keys, are priced per key.
- Number of doors and scheduling. Planned installs are booked at a time that suits you within our hours. An urgent install after a break-in, when we rearrange the schedule to get there sooner, may be priced differently from a routine appointment. Either way, you get the price first and nothing is added without your approval.

Practical tips before you call
- Don't ignore the hinge side of the door. A door that's strong at the deadbolt can still be forced at the hinges if they're held by short screws. Replace one screw in each hinge, ideally the one nearest the door stop, with a 3-inch screw that reaches the framing behind the jamb.
- A deadbolt only protects you when it's thrown. Make a habit of turning it every time you close the door, even for a quick trip to the mailbox or the side yard, because the spring latch in your knob can be slipped with a thin tool in seconds.
- Measure your backset before shopping. It's the distance from the door edge to the center of the round hole, usually 2-3/8 or 2-3/4 inch. Most current deadbolts adjust to either, but some decorative and high-security models don't, and a wrong backset can't be fixed with force.
- Fresh weatherstripping can push the door away from the stop and pull the bolt out of line with the strike. If your deadbolt starts dragging right after weatherstrip work, that's probably the reason, and moving the strike slightly is usually a small fix.
What not to do
- Cranking 3-inch strike screws until the jamb bows inward. Overtightening pulls the frame toward the stud, changes the gap around the door, and can make the bolt miss its pocket. Snug is enough, and a shim behind the strike handles a wide gap.
- Drilling freehand without a jig. A face bore that's slightly off-angle or an edge bore that drifts makes the bolt rub and the tailpiece twist. The lock works at first but wears quickly, and fixing a misdrilled hole often means a reinforcement plate or filler block.
- Forcing a binding deadbolt by pushing or lifting the door every time you lock it. That strains the tailpiece and cam until something snaps. A bolt that binds is telling you the door and strike are misaligned, and the alignment is what needs fixing.

Frequently asked questions
Are landlords in California required to provide deadbolts?
Yes. California Civil Code section 1941.3 requires landlords to install and maintain an operable deadbolt on each main swinging entry door of a dwelling unit, with the bolt extending at least 13/16 inch beyond the strike edge into the jamb. We install compliant deadbolts for rental owners throughout San Bernardino County and can key them per unit or under a master.
Why do I have to push or lift my door to lock the deadbolt?
The bolt and strike are out of alignment, often because of sagging hinges, a shifted frame, new weatherstripping or heat swelling the door. Forcing it wears out the tailpiece and cam. We diagnose the cause, adjust hinges or the strike, and set it so the key turns smoothly without any pressure on the door.
How long does a deadbolt installation take?
Installing into a door that already has standard holes is a fairly short job once we're on site. Boring a new door, reinforcing the jamb, or working on steel or double doors takes longer, and a damaged frame adds more. We'll give you a realistic time estimate for your specific door in San Bernardino when you call (951) 903-3193 and describe what you have.
Why use 3-inch screws on the strike plate?
Standard strike screws are often about 3/4 inch long and only reach the wooden jamb, which is thin softwood. A 3-inch screw passes through the jamb and the shim space into the wall stud behind it. That means a kick has to break framing, not just a strip of trim, before the door gives way.
Do you install deadbolts on steel and fiberglass doors?
Yes. Steel doors have a thin skin over foam with an internal lock block, and fiberglass doors need sharp bits to avoid chipping the skin. We locate the block, drill carefully and keep the core sealed. Many prehung steel and fiberglass doors come pre-bored for a deadbolt, which makes the install simpler and cleaner.
Is a smart deadbolt as strong as a regular deadbolt?
It depends on the model. Many smart deadbolts, including the Schlage Encode and Yale Assure lines, publish a BHMA grade or residential rating, so compare those the same way you would for a mechanical deadbolt. The installation matters as much as the lock: a smart deadbolt still needs a reinforced strike, long screws and a bolt that throws fully.
How quickly can you get to an address in San Bernardino?
We're based in San Bernardino, so most addresses in town are a short drive. Arrival time still depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
