Rekey Door Locks in San Dimas, One Door or Every Door
Short answer: Before we rekey door locks in San Dimas, find a working key for each door if you can, a photo ID that matches the address or other proof you're authorized, and a list of the doors you want changed. Missing a key for one door? We can usually pick or decode it. We work every day, 6:30 a.m. to 11:30 p.m.

Walk around almost any house in San Dimas and count the keyed doors: a front entry with a deadbolt and a knob, a back door, the door from the garage into the kitchen, a side door to the garage, maybe a slider and a steel security screen. Those locks were often installed years apart by different people, and they rarely share a brand. That matters when you rekey door locks, because each type comes apart differently and a few cheap ones can't be re-pinned at all. We look at every door you name, explain what each lock is, and give you a quote that lists them one by one before any work starts.
How this works in San Dimas
A fresh set of pins can't fix a door that fights its own lock. Doors move: wood swells during winter rains and shrinks again in dry heat, hinge screws loosen, and houses settle, so a strike plate that lined up perfectly when the lock went in may now sit a little high or low. The result is a deadbolt you have to push, pull or lift to throw, and that sideways pressure wears the cylinder, tailpiece and bolt far faster than normal use. So when we rekey door locks, we check each door's operation before and after. We look for full bolt throw, a latch that catches without a slam, hinge screws that bite, and a strike held by long screws reaching the framing. The door from the garage into the house deserves special attention. In many California homes it has spring hinges or a closer so it shuts and latches on its own, and a freshly rekeyed lock does little good if that door drifts open. Small adjustments made during the same visit usually settle these problems for good.
Work included on a typical visit
- Front door deadbolt rekeying. If the front door has a double-cylinder deadbolt, keyed on both sides, both faces get re-pinned to the same new key. While we're there, we'll mention the exit concern: building codes expect a required exit door to open from inside without a key. Many owners switch to a single-cylinder model and handle worries about glass panels another way.
- Mortise and rim cylinders. Many older front doors, and some newer high-end ones, use mortise locks: a lock body set into a pocket cut in the door edge. The cylinder threads into that body and is held by a set screw on the door's edge. We loosen the screw, unthread the cylinder, re-pin it and set the cam correctly before tightening everything back up.
- Garage entry and garage side doors. The door between the garage and the house matters more than people think. Many households leave the overhead door up while they're in the yard or driveway, which makes that inner door a front door in practice. We rekey its knob and deadbolt to the house key and check that the door still closes and latches on its own.
- Patio sliders and French doors. French doors and many fiberglass entry doors use multipoint locks that throw bolts into the head and sill as well as the side jamb. Their keys run a euro profile cylinder. Rather than re-pinning, we normally replace that cylinder with one keyed to your house key, measured to the right length so it doesn't stick out past the trim.
- Matching a door to the key you already carry. You don't always need a brand-new key. If you're adding a lock, or one door was never on your house key, we can rekey that single lock to the key you already use, provided the keyway is compatible. We decode your key's cuts and pin the cylinder to match, so nothing else in the house has to change.
How San Dimas shapes the job
Older homes in San Dimas often have a front door lock older than anyone living there: a mortise lock with a painted-over set screw, a rim lock on the back door, or knobs in keyways that few shops still stock blanks for. Most of these can be re-pinned if the lock body is sound. Where a part is obsolete, we'll offer a replacement cylinder or modern hardware keyed to match, and explain plainly why that door needs it.
Foothill homes take a beating from wind, dust and big temperature swings, and doors facing canyon winds tend to slam and drift out of alignment. When we rekey door locks up here, we pay close attention to strike position and weatherstrip pressure, because a bolt fighting a wind-loaded door wears quickly. Clearing fine grit out of each cylinder during the re-pin makes a noticeable difference after a Santa Ana season.
Busy family homes tend to have keys scattered everywhere: grandparents, babysitters, carpool neighbors, a teenager who lost theirs twice. Rekeying resets all of that in one visit. Many families key the front, back and garage entry alike for simplicity, then give older kids and helpers a keypad code instead of a metal key, so access can be removed later without paying for another rekey.
Common situations
- Consider a back door deadbolt that only throws if you pull the door toward you first. The owner has done that for years and figures a rekey will cure it. With the cylinder out, though, the bolt still binds against the strike, which proves the lock isn't the problem. The fix is a strike adjustment and longer screws during the same visit, and afterward the new key turns with a fingertip.
- Picture a two-story stucco home with a bronze handleset at the front. The owner assumes the grip and the deadbolt each hold a cylinder and budgets for two. In fact, the thumb latch below is unkeyed, so the handleset has a single cylinder in its deadbolt. We'd re-pin that one, rekey the back door knob and deadbolt, and the final quote comes in lower than the owner expected.
- Say the front door wears a Schlage Encode while the back and garage doors still have their original Kwikset knobs and deadbolts. The owner wants one key. Because the brands use different keyways, we'd re-pin the Encode's Schlage cylinder, replace the Kwikset hardware on the other doors with Schlage keyed to match, and then reset the Encode's codes and app users as a separate step.
- Imagine a 1950s bungalow with its original mortise lock on a solid wood front door. The set screw is hidden under several coats of paint, and the cylinder may never have been out of the door. We'd score the paint, back the screw out, and unthread the cylinder slowly so the threads in the lock body survive. The re-pinned cylinder goes back in with a light shot of dry lubricant.
How the visit works
- Tell us which doors and what's on them. Call (951) 903-3193 and list the doors you want rekeyed: front, back, garage entry, side door, slider, screen, gate. Tell us the brand if you can read it on the latch face or a key head. Kwikset, Schlage and other makers take different parts, so the more we know, the better stocked we arrive.
- Confirm you're authorized. Renters, property managers and relatives house-sitting each need slightly different proof. A tenant may need the landlord's written permission, depending on the lease. A manager shows written authorization from the owner. If you're unsure what counts, ask when you call, and we'll tell you exactly what to have ready.
- Check each door before touching the lock. Before removing anything, we operate each door: throw the deadbolt with the door shut, turn the knob, let the door swing closed by itself. That tells us whether a binding bolt or sticky latch is a door problem or a lock problem, which changes what actually needs fixing.
- Re-pin each cylinder, one door at a time. For doors keyed to match, we pin every cylinder to the same bitting from a single key code. For doors that need a separate key, we choose a code with no near-matching cuts, so one key can't accidentally turn the other door's lock.
- Test from both sides. Keys cut in the van get deburred and tried in every lock they're meant to open. If a key feels rough or catches, we recut it. Testing every key in every intended door is tedious, and it's exactly the step that prevents a callback later.
- Hand over keys and a door list. You get the agreed number of keys, and we suggest counting them in front of us. We also leave a simple list of which doors take which key, useful later when a cleaner, contractor or relative asks for access and you need to decide what to hand over.
How we quote the job
- Brands and keyways. Some keyways are easier to stock than others. Kwikset KW1 and Schlage SC1 are everywhere, while older brands, imported hardware or six-pin cylinders may need specific pins or blanks. We carry broad stock, but a rare keyway can mean a return trip, which we'd flag before starting.
- Door adjustments and small parts. Weak springs and rusted pins are replaced as part of a normal rekey. Bigger parts aren't: a latch assembly, a lever cassette or a full strike box. We price those openly so the rekey quote stays clean and you choose which repairs to approve that day.
- Keys and scheduling. Ask about timing when you call. Some jobs fit an early slot before work, others need a longer window for a full set of doors. We're out every day from 6:30 a.m. to 11:30 p.m. Saturdays and Sundays are included, so pick whichever day suits a tight week.
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 Dimas.
Mistakes to avoid
- Hiring whoever answers first from an online listing without checking for a license. California requires locksmith companies to be licensed through BSIS. Ours is LCO7891, and you can confirm it at search.dca.ca.gov. A legitimate locksmith also gives you a price before touching any door.
- Buying a DIY rekey kit for the wrong brand. Kits are keyway-specific, and the pins, springs and follower in a Kwikset kit won't help with a Schlage cylinder. Even with the right kit, one slipped follower can launch drivers and springs across the floor and leave the door unusable.
- Assuming every lock can be rekeyed. Patio slider cylinders, storm door handles and some screen door locks are wafer designs or proprietary parts. Paying for an attempt on those wastes time and money; ask the locksmith to identify each lock first and quote replacements where they're needed.
What to do before we arrive
- Plan around our hours: every day from 6:30 a.m. to 11:30 p.m. We're closed overnight. An early weekday slot before work suits many households in San Dimas, and a Sunday visit works well when several doors are on the list.
- Clear a path to each door, especially the garage entry and the slider. Boxes stacked against a garage door or a couch pushed up to a slider slow the work and make it hard to test the door's swing. Ten minutes of moving things keeps the visit efficient.
- Rekey door locks you plan to keep, and replace only the ones that are failing. A wobbly knob or a latch that sticks is better replaced and keyed to match than re-pinned. Paying to rekey a lock you'll swap out next year rarely makes sense.
- Gather every key you own, including the strays in the kitchen drawer. A key you can't place might fit the screen door or the side gate, and having a working key makes each lock faster to rekey. Keys that fit nothing get set aside, and you can toss them once the job is done.

Frequently asked questions
Can every door lock be rekeyed?
Most can. Standard pin tumbler deadbolts, knobs, levers, handlesets and mortise cylinders from Kwikset, Schlage, Baldwin, Yale and similar brands rekey well. The usual exceptions are cheap wafer locks on patio sliders, storm doors and some screen doors, plus certain proprietary smart lock cylinders. When a door's lock can't be re-pinned, we tell you before starting and offer a replacement keyed to match.
How long does it take to rekey door locks?
Once a standard cylinder is out of the door, re-pinning it is quick. A typical house with a front, back and garage entry door is usually a single visit, often finished in an hour or two depending on the hardware and how many keys we cut. Mortise locks, smart locks and doors that need adjusting add time. We'll estimate it when you call.
Can interior door locks be rekeyed?
Keyed interior locks can, such as an office, storage room or bedroom door in a shared rental. Privacy locks on bedrooms and bathrooms have no cylinder at all, just an emergency release hole, so there's nothing to rekey. If you want an interior door that takes a real key, we can install a keyed entry lever and key it however you like.
Can I have my door locks rekeyed as a renter?
Usually with the landlord's permission. Most California leases address lock changes, and many require giving management a copy of the new key. Under Civil Code sections 1941.5 and 1941.6, landlords must change locks within 24 hours of a tenant's written request in certain protective-order situations. Check with your landlord first, then call us and we'll handle the rest.
What do you need from me before you rekey door locks?
A photo ID that matches the address, or other proof you live there or own the property, such as a utility bill, closing papers or a lease. Renters may need the landlord's permission. It also helps to have any keys you have for each door and a clear idea of which doors should share a key and which shouldn't.
Will my deadbolt and knob end up on the same key?
They should, and we make sure of it. A front door often has two cylinders, one in the deadbolt and one in the knob or lever, and both need re-pinning to the same new key. If the knob is worn or loose, we may suggest replacing it with a matching model keyed alike instead of spending money re-pinning it.
How far is San Dimas from your base?
San Dimas is about 34 miles from our San Bernardino base, roughly 37 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.
