Rekey Door Locks in Ontario, One Door or Every Door
Short answer: Most residential door locks can be rekeyed: Kwikset and Schlage deadbolts, knobs and levers, handlesets, mortise locks and the backup cylinders in many smart locks. The usual exceptions are inexpensive wafer locks on patio sliders, storm doors and some screen doors, plus a few proprietary smart lock cylinders. For those, we swap the cylinder or the lock and tell you before starting.

A rekey is also the cheapest moment to find out how your doors are really working. While a cylinder is out, we can see whether the deadbolt reaches full throw, whether the strike plate lines up, and whether the latch is dragging on a door that has dropped on its hinges. Plenty of homeowners in Ontario have learned to lift the back door or lean on it before the bolt will turn, and they assume the lock is wearing out. Often it's the door. When we rekey door locks, we check each one for these problems and tell you what we'd adjust.
How this works in Ontario
Each kind of door hardware hides its cylinder in a different spot, and that drives how long the job takes. A deadbolt is the simplest: two screws release the interior thumbturn and the exterior cylinder slides out. Knobs and levers use a small release catch, and the cylinder comes out of the knob body. On a handleset, the key almost always lives in the deadbolt section above the grip, while the thumb latch below has no cylinder at all. Older front doors with mortise locks use a threaded cylinder held by a set screw on the edge of the door, and that screw is sometimes buried under decades of paint. Rim cylinders, common on gate locks and some older back doors, come out from the inside with two long screws. French doors and many fiberglass entry doors with multipoint locks use euro profile cylinders, which we normally replace with a new cylinder keyed to match rather than re-pin. Patio sliders and storm doors are the wild cards: many use inexpensive wafer locks that can't be re-pinned, so we swap in a better lock or add a secondary one.
Work included on a typical visit
- Knob and lever entry locks. The knob or lever below your deadbolt has its own cylinder, and it's the one people forget most. On most models a small release catch lets the knob slide off, the cylinder comes out of the knob body, and we re-pin it to match the deadbolt. If the latch sticks or the knob wobbles, we'll point it out before spending your money on it.
- Handlesets and gripsets. Handlesets often carry a premium finish such as oil-rubbed bronze, satin nickel or polished brass, and they're expensive to replace. Rekeying keeps that finish on the door. We work carefully around the escutcheons, use the right drivers for the decorative screws and wipe down every surface we've touched before packing up.
- Mortise and rim cylinders. The trickiest part of rekeying an old mortise lock is usually paint. Decades of coats can bury the set screw and glue the cylinder to the faceplate. We cut the paint carefully rather than forcing the cylinder, which can strip the threads inside the lock body. If the mortise lock itself is worn out, we'll tell you plainly.
- Security screen and storm doors. Storm doors use lighter latch hardware with a small keyed handle, often a wafer lock that can't be re-pinned. If the storm door needs to be on your key, we look for a keyed replacement handle that fits the door's hole pattern. If not, many owners simply leave the storm door unkeyed and rely on the entry door behind it.
- Smart lock backup cylinders. Some app-based locks, including certain Lockly and Ultraloq models, use backup cylinders with proprietary keyways and few spare parts available. Those may not take a standard re-pin. Our honest options are to leave that key as it is, order a replacement cylinder from the manufacturer if one exists, or swap the lock. We'll tell you which applies before quoting.
Local factors in Ontario
Apartment door locks follow the lease. Renters should get the landlord's written approval before any door is rekeyed, and many leases require giving management a copy of the key. Landlords handling a turnover usually want the entry deadbolt and knob rekeyed while mailbox and common-area keys stay with management. We'll rekey door locks inside the unit, cut keys for both tenant and owner, and note the change for your records.
Newer tracts usually come with builder-grade Kwikset or Schlage knobs, levers and deadbolts, often keyed so the builder's crews could get in during construction. Those locks rekey easily, and SmartKey models can often be reset in moments. The bigger question is how many people held keys during the build and the punch-list phase. Rekey door locks you inherited from the builder, then check that the strikes were set with screws long enough to reach the framing.
Older homes in Ontario 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.
Situations this covers
- 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.
- Picture a renter in an apartment near ONT Field whose roommate moved out with a key. Before we rekey door locks in a rental, we'd ask for the landlord's written OK, since most California leases address lock changes, and suggest giving management a copy of the new key afterward. With that settled, the deadbolt and knob get re-pinned and the former roommate's key no longer turns either one.
- A typical evening call in Ontario: the door from the garage into the kitchen won't latch unless someone slams it. The owner wanted that lock rekeyed after a house sitter left and assumed the knob was failing. It isn't. The spring hinges have lost tension and the strike sits slightly high. We'd re-pin the knob and deadbolt, tension the hinges and reset the strike, and the door closes on its own again.
- A typical ADU setup: a converted garage behind a house in Ontario now has its own entry door with a lever and a deadbolt. The owners rent it to a relative and want their house key to open it, but they don't want the ADU key opening the main house. We'd explain a small master key arrangement, pin the ADU door accordingly, and write down which keys go to whom.
From your call to the finished job
- Tell us which doors and what's on them. A quick photo of each lock helps more than any description. Send pictures of the outside face of each knob, deadbolt or handleset and of the keys you use now. From those we can usually identify the brand, keyway and cylinder type and give you a much tighter quote over the phone.
- Confirm you're authorized. Verification protects you more than it protects us. The same rule that has you showing ID also stops a stranger from having your locks rekeyed while you're at work. It takes a minute, and we do it every time, including for a single-door job on a quiet afternoon.
- Check each door before touching the lock. We look at the strike plate, hinge screws, latch alignment and the gap around the door. A door that has dropped a little on its hinges drags the bolt across the strike, and no amount of re-pinning cures that. We point out anything we'd adjust and add it to the quote as a separate line.
- Re-pin each cylinder, one door at a time. We work one door at a time so the house stays secure. The cylinder comes out, the plug is pushed out with a follower so the springs and driver pins stay put, and new key pins are set to the new key's cuts. Old pins are discarded, not reused.
- Test from both sides. Each rekeyed lock is tested with the door open and again with it closed, from outside with the key and inside with the thumbturn. We also try one of your old keys to confirm it no longer turns. Only then does the next door come apart.
- 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
- How many doors and cylinders. A single door is a small job, but the drive to reach it is the same as for six doors. That's why adding a back door or garage entry to a one-door rekey usually costs much less per lock than the first. We quote the whole list at once so you can see what's worth including.
- Whether you have working keys. A working key for each door makes rekeying faster, because the plug can be turned to release the cylinder. Without a key, the lock has to be picked, decoded or occasionally drilled before it can be re-pinned. That extra step is the most common reason a phone quote changes on-site.
- Door adjustments and small parts. Adjusting a strike plate, adding longer screws or tightening loose hinges adds a little time and occasionally a part, such as a reinforced strike. These fixes often matter as much as the rekey itself, because a door that binds will wear out a freshly pinned cylinder.

Common errors that cost time and money
- 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.
- Rekeying only the deadbolt and forgetting the knob. Many front doors have two keyed cylinders, and if the knob still takes the old key, anyone holding it can walk in whenever the deadbolt isn't thrown. Rekey both, or swap the knob for a passage set with no keyhole at all.
- Lubricating with oil or grease. A shot of household oil seems to help for a week, then the film gathers dust and the pins start to drag. Locksmiths use dry graphite or a PTFE lock lubricant, applied sparingly. Inside a cylinder, more lubricant is never better.
Practical tips before you call
- Before calling, walk the house and count keyholes instead of doors. A front entry may have two, a handleset one, the garage entry two, the security screen one. Jot the brand from each latch face or key head beside it. That short list gets you a phone quote that holds up once we're standing at your door in Ontario.
- Pay attention to how the garage-to-house door closes while we're there. If it doesn't close and latch on its own, mention it. A properly tensioned spring hinge or closer keeps that door secure without anyone having to remember to pull it shut on the way out.
- 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
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.
Can a sliding glass door lock be rekeyed?
Sometimes. Many patio sliders use small wafer cylinders or proprietary parts that can't be re-pinned. When the slider's lock accepts a standard cylinder, we can key it to your house key. When it doesn't, we can install a keyed replacement that fits the cutout, or add a foot lock or charley bar so the slider is secure from inside.
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 you rekey my security screen door?
Often, yes. Many steel security screen doors use cylinders in a Kwikset or Schlage keyway, which we re-pin to your house key like any other lock. Some use proprietary cylinders that have to be replaced instead. Either way, bringing the screen onto your main key means one less key on the ring and fewer forgotten copies in circulation.
When can you come out to rekey door locks in Ontario?
We work every day from 6:30 a.m. to 11:30 p.m., weekends included. We're closed overnight. Call (951) 903-3193, tell us which doors and what hardware is on them, and we'll give you a quote and an honest ETA. Early mornings and evenings suit people who would rather not take time off work.
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 Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 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.
