Residential Lock Replacement in San Bernardino, CA — Replacing a damaged lock after a break-in

Plenty of houses in San Bernardino end up with a drawer full of keys: one for the original front deadbolt, another for the back door someone replaced after a lost key, a third for the garage entry the builder installed, plus a screen door key nobody can identify. Replacing locks one at a time, from whatever was on the shelf, is how that happens. A planned residential lock replacement fixes it. We choose hardware that shares a keyway, key every exterior lock to the same key, and can often match your current key so nobody needs new copies. Julian's Locksmith handles most homes on site in a single visit. Call (951) 903-3193 to plan yours.

Residential Lock Replacement in San Bernardino: what to expect

Residential lock replacement doesn't always mean replacing everything on a door. A typical exterior door has three separable parts: the knob or lever set, the deadbolt, and the strikes in the frame. Often only one of them has failed. A deadbolt with a cracked housing can be swapped while the matching knob stays. A worn but otherwise solid deadbolt may only need a new cylinder, including an upgraded or high-security cylinder that fits the existing body. A strike torn from the frame can be replaced with a heavy-duty version without touching the lock at all. Full replacement makes the most sense when several of those parts are worn at once, when the hardware comes from a discontinued line with no parts, when you want a higher security grade throughout, or when consistent style and keying across the house are part of the goal. We'll tell you which approach fits each door, because replacing a whole set to fix one failed component spends money on parts that still had years of life left in them.

How we can help in San Bernardino

  • Handleset replacement. Front-entry handlesets are the most visible hardware on a house, and replacements often come with a door repaint or exterior refresh. We help choose finish and style, then install the grip, deadbolt and interior trim with correct spacing and snug fasteners so the set sits flat against the door and stays tight through years of use.
  • Mortise lock replacement and conversion. Mortise locks vary in case size, backset and faceplate length, especially on doors built before the 1950s. We measure the pocket, the trim holes and the spindle position before ordering. A close match keeps your door's original look; a conversion plate is the fallback when no current mortise body fits the pocket without major cutting.
  • Patio and French door hardware replacement. Sliding door handle sets and mortise latches are specific to the door's manufacturer and frame profile. When the latch or handle is broken beyond repair, we identify the door, match the replacement latch and handle, and fit a keyed version if you want to lock the slider from outside. A secondary foot lock is an inexpensive addition.
  • Garage entry and side door locks. Some homeowners want the garage entry to be the keyless door, since kids and family usually come in that way. A keypad deadbolt or keypad lever there, with a backup cylinder keyed to match the rest of the house, removes the need for a hidden key under the mat while every door stays on one key.
  • Keying the new locks. Locks come from the factory with random keys, so a box of new hardware means a pile of different keys. We rekey each cylinder on site before installing it, cut the number of copies you need and test each key in every lock. You leave with one key that runs the front, back, side and garage entry.

What's different about San Bernardino

Foothill homes deal with dust, wind and fire-season evacuations. Replacement hardware there should hold up to grit, lock quickly when you're leaving in a hurry and be easy for everyone in the household to operate. We often install single-cylinder deadbolts with easy thumb-turns and recommend keeping a working physical key for every smart lock, since power and internet can drop during wildfire events.

Inland heat is hard on replacement hardware. Dark finishes on west-facing doors get hot to the touch, cheap coatings fade and peel, and electronic locks in direct sun burn through batteries sooner. For residential lock replacement in the hotter parts of San Bernardino, we favor durable finishes, solid metal construction, keypad models with suitable temperature ratings, and lighter finishes on doors that bake in afternoon sun.

Owners of student rentals replace locks more often than most, because keys disappear at the end of every lease. Rekeyable hardware or keypad deadbolts with codes that change between tenants cut the cost of turnover. For shared houses, we can fit bedroom doors with keyed entry levers that always open freely from inside, while the front door runs on a common key, if the lease allows.

Common situations

  • Picture an older homeowner whose arthritis makes round knobs and a stiff deadbolt a daily struggle. We replace the entry knob with a lever, swap the deadbolt for one with a larger thumb-turn, and suggest a keypad deadbolt on the garage entry so a code replaces fumbling with keys. Every keyed cylinder stays on one key, and the doors close with light pressure.
  • Imagine a host renting out a backyard casita as a short-term rental who's tired of meeting guests to hand over keys. We replace the casita's keyed deadbolt with a keypad deadbolt that supports unique guest codes, key its backup cylinder separately from the main house, and show the host how to delete codes after each stay. The main house remains on its own key.
  • For example, a custom-built home has a 2-1/4-inch-thick mahogany front door, and the owner wants to replace the keyed deadbolt with a Wi-Fi smart lock. A standard unit won't reach through the door, so we pick a model whose maker offers a thick-door kit, confirm the bolt runs freely into a reinforced strike, install it and set up codes and app access with the owner.
  • For example, a house with daily sprinkler spray and hard afternoon sun on its back door has exterior locks with peeling finish and cylinders that corrode within a few years. The owners want hardware that lasts. We replace them with PVD-finish levers and deadbolts made for outdoor exposure, suggest moving the worst sprinkler head, and dry-lubricate the new cylinders before handing over keys.

How the visit works

  1. Inventory and goals. We start with a list: front, back, side and garage-entry doors, sliders, French doors, screen doors and any interior locks you want changed. For each, we note what's there now and what you want it to become. A clear list keeps the quote accurate and makes sure the right hardware is on the van.
  2. Measure the door prep. Older and custom doors don't always follow the modern pattern. We check for mortise pockets, unusual backsets, oversized holes from previous hardware and thick doors that need extension kits. Catching those details before anything is ordered prevents the classic mistake of a lock that doesn't fit the door it was bought for.
  3. Choose the hardware. Keyway selection is part of choosing. If every lock will share one key, the hardware needs compatible cylinders. We confirm that before ordering, and if your preferred decorative brand uses a different keyway, we look for a cylinder option that lets it match the rest of the house.
  4. Quote, approval and verification. Before replacing any lock, we verify ownership or authority: photo ID matching the address, a deed or tax bill, a lease with landlord approval, or a property manager's work order. That protects you from someone else changing your locks. With approval and verification done, we confirm the schedule and parts.
  5. Remove and install. Doors that need new holes get them drilled with proper jigs so the lock sits square. Old holes the new hardware doesn't cover are filled and can be finished. For smart locks, we also mount the interior unit, install batteries and pair the lock with your app before moving to the next door.
  6. Key, test and hand over. Before we leave, we walk through each door with you: how the locks work, how to change smart lock codes, which lubricant to use and when to tighten trim. Any door we noticed with problems beyond the lock, such as a sagging hinge or worn weatherstrip, gets mentioned too.

What affects the cost

  • Number of locks and keying. Whole-house replacements involve the most hardware but the lowest cost per door. If the budget is tight, we can replace the exterior locks now, keyed alike, and handle interior hardware later in the same finish, so the house still matches once everything is done.
  • Lock type. A keypad deadbolt costs more than a keyed one and takes longer to install because of programming and testing. Retrofit smart locks that keep your existing exterior cylinder can cost less overall when the deadbolt underneath is still in good condition.
  • Who supplies the hardware. You can buy locks yourself and pay only for installation, or have us supply them. Supplying your own can save on hardware, but returns and fit problems become your errand. When we supply the hardware, we're responsible for it fitting the door and keying correctly.

Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in San Bernardino.

Advice before you book

  • In sun-exposed or sprinkler-sprayed spots, choose hardware with a durable PVD-type finish rather than a basic lacquered or painted coating. Those finishes resist fading and tarnish much better. Matte black and oil-rubbed bronze vary widely between brands, so compare samples in daylight before committing.
  • Before installing a smart lock, check your Wi-Fi signal at the front door and learn how your model handles a dead battery. Some use a backup key; others have external terminals for emergency power. Knowing the backup method before you need it can save you a lockout.
  • When replacing locks on a rental, choose hardware you can rekey quickly at turnover and deadbolts with at least a 13/16-inch throw, which is what California's rental deadbolt rule describes. Keep a key log for each unit, and if you manage several properties, consider keeping spare cylinders ready.
  • Measure before you shop: the distance from the door edge to the center of the knob hole is the backset, usually 2-3/8 or 2-3/4 inches. Most new locks adjust for both, but confirm. Measure door thickness too; anything over 1-3/4 inches may need an extension kit from the manufacturer.

Common errors that cost time and money

  • Letting a tenant or contractor replace locks without the owner getting keys or records. Owners end up locked out of their own property, or unsure who holds keys. Whoever does the replacement, make sure the owner receives keys and a note of brand, keyway and key count for every lock.
  • Installing a double-cylinder deadbolt on the only exit door without thinking about emergencies. Needing a key to get out can cost precious seconds in a fire, especially for kids or guests. If you choose one anyway, understand the code limits and keep the key in a fixed spot nearby.
  • Reusing the old strike plate and short screws with a new deadbolt. The lock may be Grade 1, but if the strike is held by screws that only reach the soft jamb, a kick tears it out. Replace the strike and use screws that bite into the framing.

Reaching San Bernardino

San Bernardino is our home base, so most addresses in town are a short drive. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Once the evening commute thins out on SR-259, drive times usually shrink. That makes an evening call before closing a practical option for non-urgent jobs that you couldn't fit into the workday.

Frequently asked questions

Do you replace sliding patio door and French door locks?

Yes. Slider latches and handles are specific to the door's manufacturer, so we identify the door and match the replacement, adding a keyed option or a secondary foot lock if you like. French doors and fiberglass doors with multipoint locks need a compatible mechanism that fits the existing edge cutout. Discontinued designs sometimes need adapter plates or a special order.

Can all my new locks work with one key?

Yes, as long as they share a keyway. Schlage and Kwikset, for example, use different keyways, so we choose hardware with compatible cylinders and key every new lock to the same combination during installation. Some decorative brands offer cylinders in common keyways, which lets premium hardware share a key with everything else. One key for the front, back, side and garage entry is the usual goal.

What should be replaced after a break-in?

Anything the intruder damaged or might have keys for. That often means the deadbolt and entry set on the forced door, the strike and sometimes the jamb. If keys were stolen, every lock they fit should be rekeyed or replaced. We make the house lockable that day, document the damage for police and insurance, and can upgrade to stronger hardware with reinforced strikes.

Do you need proof that I own the house?

Yes. Before replacing locks, we confirm you own the home or are authorized to change its locks: photo ID with the address, a deed or tax bill, or a property manager's work order. Tenants generally need the landlord's written approval unless state law gives them a specific right to change the locks. These checks protect you from unauthorized lock changes.

What lock rules apply when replacing locks on a California rental?

Civil Code §1941.3 requires landlords to provide operable deadbolts on main swinging entry doors and working window locks, and it defines a deadbolt by a minimum throw of 13/16 inch. Under Civil Code §1941.5 and §1941.6, a landlord must change the locks within 24 hours of a tenant's written request in certain protective-order situations. Rekeying or replacing locks between tenants is also widely recommended.

Can you replace an old mortise lock?

Yes. When an original mortise lock can't be repaired, we look first for a modern mortise lock that fits the existing pocket and trim holes, which preserves the door's look. If none fits, conversion plates let a standard bored lock and deadbolt mount over the old pocket. We avoid recutting solid older doors whenever a cleaner option exists.

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.
