Residential Lock Replacement in Chino: Choosing What Goes In
Short answer: Yes, you can replace every lock in your house in one visit. Julian's Locksmith replaces deadbolts, entry sets, interior knobs, patio hardware and garage-entry locks across Chino, keys the new exterior locks to a single key, and sets the strikes so everything closes smoothly. You can supply your own locks or choose from ours. Call (951) 903-3193.

Plenty of houses in Chino 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 Chino: what to expect
Most modern residential doors are bored to a common pattern, and replacement locks are built around it. The main hole through the face of the door, called the cross bore, is 2-1/8 inches across. A 1-inch hole in the edge holds the latch or bolt. The backset, measured from the door's edge to the center of the main hole, is usually 2-3/8 inches on interior and older doors and 2-3/4 inches on many entry doors, and most current locks have adjustable latches for both. Exterior doors are typically 1-3/4 inches thick and interior doors 1-3/8, while thicker custom doors need extension kits. Then come the details that trip people up: the shape of the latch faceplate (drive-in, square corner or round corner), the distance between the knob and deadbolt holes, and, on handlesets, the spacing of the grip's mounting holes. Older doors may predate these standards entirely. We measure every one of those dimensions before recommending hardware, so the new lock fills the existing prep instead of leaving gaps or needing fresh holes.
What we can do on-site
- Knob and lever entry set replacement. Swapping a knob for a lever, or one brand for another, usually reuses the existing holes when backset and bore match. We confirm the latch length, check the faceplate shape against the old mortise, and replace the strike if the new latch needs a different opening. The finished door should close softly and latch the first time.
- Mortise lock replacement and conversion. Some homeowners upgrade from an old residential mortise set to a modern mortise entry lock with a deadbolt and a standard cylinder. That keeps the solid, single-unit construction mortise hardware is known for, while adding a stronger bolt and a cylinder that can be keyed to the rest of the house.
- Garage entry and side door locks. Side yard doors and detached garage doors take sun, dust and the occasional shoulder bump from someone carrying things. We replace their locks with weather-resistant hardware, add a deadbolt where there was only a knob, and key them with the house or separately, depending on who should have access to what.
- Keying the new locks. Replacement is the best time to get every exterior door on one key. We choose hardware that shares a keyway, such as Kwikset KW1 or Schlage SC1, and key each new lock to the same combination before installation. If you prefer to keep your current key, we can usually pin the new cylinders to match it.
- Replacement after forced entry. When a door has been kicked or a cylinder wrenched, the lock, strike and jamb are often all damaged. We remove the broken hardware, rebuild or reinforce the frame, install new locks suited to the door, and key them differently from the old ones so any keys that went missing in the incident stop working.
How Chino shapes the job
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 Chino, we favor durable finishes, solid metal construction, keypad models with suitable temperature ratings, and lighter finishes on doors that bake in afternoon sun.
In family homes, replacement usually centers on how kids use the doors: levers they can work, a keypad on the garage entry so nobody needs a hidden key, privacy locks that open from the hallway, and deadbolts keyed alike so one key goes on a teenager's ring. We plan a residential lock replacement in Chino around the doors your household actually uses most.
Newer homes usually have standard door prep, which makes swapping hardware easy, but they also come with builder-grade locks many owners upgrade early. A common residential lock replacement in newer Chino tracts is trading the exterior builder hardware for Grade 1 deadbolts and Grade 2 levers, adding reinforced strikes and keying everything to a new key, since builders and subcontractors had access during construction.
Common situations
- 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.
- A typical garage-entry upgrade: the door from the garage into the laundry room has a builder knob that locks with a push button and no deadbolt. The family wants better security without more keys. We install a keyed lever and a deadbolt keyed to the front door, set the latch to catch with the door's closer, and make sure the strike screws reach solid framing.
- Picture a front door with a glass sidelight and a double-cylinder deadbolt installed years ago so nobody could break the glass and reach a thumb-turn. The new owners worry about getting out quickly in a fire. We replace it with a single-cylinder Grade 1 deadbolt and suggest security film for the sidelight, which answers the glass concern without requiring a key to exit.
- 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.
From your call to the finished job
- 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.
- Measure the door prep. At the house, we measure each door before recommending hardware: backset, cross-bore and edge-bore size, door thickness, faceplate shape, the spacing between knob and deadbolt holes, and handleset mounting holes. Those numbers decide which replacement locks fit cleanly and which would need new drilling.
- 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.
- Quote, approval and verification. You get an itemized quote: hardware for each door, labor, any strike or frame work, and keying. Nothing starts until you approve it. Because we're changing locks, we confirm you own the home or have the owner's authorization; tenants need written landlord approval unless state law gives them a specific right to change locks.
- Remove and install. We remove the old hardware, clean and square the bore and edge holes, fit new latches and bolts to the faceplate pockets, and install the locks to the manufacturer's specifications. Strikes go in with long screws into the framing. Each door stays lockable throughout, so the house is never left open between steps.
- 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.
Pricing factors
- Hardware grade and brand. Smart locks span a wide price range depending on connectivity (Bluetooth, Wi-Fi, Z-Wave or Matter), keypad type and build quality. We explain what each feature does at your particular door, so you don't pay for app features you won't use or skip the ones you'd miss.
- Number of locks and keying. Each door adds hardware and installation time, but replacing several locks in one visit spreads travel and setup across all of them. Keying every new cylinder to one key adds a small amount per lock, and it's far simpler than carrying a separate key for each door afterward.
- Reinforcement, travel and timing. As a mobile service based in San Bernardino, we include travel in the visit, and distance within our service area affects that part. We work every day from 6:30 a.m. to 11:30 p.m. Planned replacements can be scheduled to suit you.

Practical tips before you call
- Spend the most on the main entry deadbolt and its strike. That's the lock most likely to be tested by force. A Grade 1 deadbolt with a reinforced strike and long screws protects you more than upgrading every interior knob in the house to a premium brand.
- 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.
- Keep a record of your locks: brand, model, finish and keyway, plus the key code if one came with the hardware. When you add a lock later or need parts, that record lets a locksmith match everything without guessing. Store a photo of it with your home documents.
- 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.
What not to do
- Choosing hardware on looks alone. Some attractive lever and handleset lines use soft die-cast parts and weak springs that sag within a few years. Check the ANSI/BHMA grade on the package and the finish rating before committing, especially for exterior doors that get daily use.
- Buying a lock before measuring the door. Backset, bore, thickness and faceplate shape all have to match, and a mismatch means new holes, a sloppy fit or a return trip. Measure first, or have a locksmith look before you buy, especially on older or custom doors.
- Mixing brands with different keyways across the house. It looks fine on installation day, then you're carrying three keys and can't key them alike later without replacing cylinders. Choose one keyway family for every keyed lock before you start buying hardware.

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 you replace a handleset without leaving holes?
Often. We measure your current handleset's mounting hole spacing and look for a replacement that matches it. When nothing in your preferred style lines up, the options include a backplate that covers the old marks or carefully filled and refinished holes. We show you those options before you choose, since the front door is the most visible place for a patch.
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.
What grade of lock should I put on my front door?
For the main entry, a Grade 1 or solid Grade 2 deadbolt is a sound choice, paired with a reinforced strike and screws long enough to reach the framing. Grade 3 is the minimum residential level and common on builder hardware. The strike and frame matter as much as the lock, so we look at both during a residential lock replacement in Chino.
Will you install locks I bought myself?
Yes. We check the hardware against your door before starting and tell you if anything won't fit, such as the wrong backset or a handleset with different hole spacing. If the locks need keying alike, we can rekey them on site. When you supply the hardware, returns and product defects are handled through the store or the manufacturer.
How much does residential lock replacement cost?
The total depends on hardware grade and brand, the number of doors, whether the new locks fit the existing holes, the lock types involved and whether you supply the hardware. Keying alike and strike reinforcement add smaller amounts. We measure, recommend options and give you an itemized quote before any work starts, so you can adjust the plan to your budget.
How far is Chino from your base?
Chino is about 36 miles from our San Bernardino base, roughly 42 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
