Rekey or Replace Locks: A Ontario Locksmith's Decision Guide
Short answer: Rekeying changes who can open a lock; it doesn't change how well the lock resists attack. Replacement changes both, but only improves security if the new lock is better than the old one, and a bargain-bin box lock often isn't. In Ontario, we compare grade, brand and condition before recommending either, and we tell you when the simpler fix is the right one.

Sometimes you have time to think, and sometimes the decision arrives with a lost key ring, a break-in or a deadbolt that won't turn. Julian's Locksmith works every day from 6:30 a.m. to 11:30 p.m., so a decision that lands while we're closed overnight may need a temporary fix first. For urgent cases in Ontario, we secure the door first and settle rekey or replace afterward, when you can see the options clearly. Call (951) 903-3193 and tell us what happened.
What to know first in Ontario
Some cases aren't close calls. Replace when the latch or bolt is damaged, when the lock has been drilled, punched or pried, when a key sticks in a cylinder that has seen better days, when the finish has worn to bare metal, when screws strip out of soft brass, or when a low-grade lock guards a door that faces an alley or back lot. Rekey when the hardware is solid and attractive, when it is a heavy decorative handleset or mortise lock that would be costly to replace and hard to match, when an HOA or landlord requires the existing look, or when you need fresh keys fast. Rekeying is also the quick route for a rental turnover or a row of identical doors. Between those two poles are the gray cases, and gray cases are where a short conversation at the door pays for itself. Weather plays a part too: sun and heat age finishes and plastic parts faster than people expect, so a lock that looks fine from inside may be tired on the outside.
Work included on a typical visit
- Rekeying a lock that's worth keeping. A rekey is also a chance to improve a lock a little. If the cylinder has room, we can add spool or serrated security pins that make picking harder. It's still a pin tumbler lock and won't stop a drill or a kick, but it's a modest upgrade for very little extra work.
- Handlesets and decorative entry hardware. Finish deserves its own thought. Oil-rubbed bronze wears through to brass at the grip, polished brass tarnishes unevenly, and satin nickel stays quiet. Replacing one handleset with a different finish beside others looks off. We show you samples and tell you honestly when rekeying is better than chasing a discontinued color.
- Mortise locks and older hardware. A mortise lock sits in a deep pocket cut into the door, and replacing the whole body means reworking that pocket. Its threaded cylinder, though, comes out separately. Rekeying that cylinder or swapping it for a new one makes new keys possible without touching the body, which is usually the practical answer.
- Smart locks and keypads: the key side still matters. Retrofit smart locks clamp onto the interior side of your existing deadbolt and leave the exterior as it is, so your key and its keying still count. Full smart deadbolts replace the entire assembly. We help you choose between the two based on door prep, battery access and how you actually use the door.
- Rental, HOA and matching-finish rules. When one lock gets replaced, the others suddenly look different. You have three options: replace the set in one finish, rekey and keep the older locks, or accept a mismatch on a door nobody sees. We lay those choices out so appearance doesn't surprise you after the work is done.
How Ontario shapes the job
Older homes in Ontario often carry hardware worth saving: heavy brass deadbolts, glass knobs, mortise sets with decorative plates. Rekey those, because replacements rarely match the quality or the look. Replace what the years have worn out, such as loose spindles, painted-over latches and thin add-ons from the 1980s. Door prep in older houses can be non-standard, so we measure before suggesting any swap and say so when a carpenter should look at the frame.
Storefronts in Ontario run on aluminum-framed glass doors with narrow-stile locks, such as Adams Rite, and the cylinder is often the only part worth changing. Rekey the cylinder when a key is lost or an employee leaves; replace the lock if it sticks or the latch is worn. Because you can't leave a storefront open, we schedule around your opening so the door is working and secured when you are.
Newer homes near Ontario International Airport usually come with builder-grade locks and thin strike plates. They work, so a rekey after closing is often enough to retire any construction keys. The front door is where replacement can pay off: a Grade 1 or Grade 2 deadbolt with a reinforced strike makes a real difference. Rekey the rest, key the doors alike, and spend where it adds protection.
Example situations
- Original 1990s builder knobs on a house near Ontario Mills: the spindle is loose, the key sticks, and a screw has stripped. The owner wants new keys after a roommate moved out. Re-pinning a lock this tired would be money spent on borrowed time, so we replace the three entry locks with Grade 2 hardware and rekey the interior ones.
- A mixed-brand house in Ontario: Schlage on the front, Kwikset on the back, an unknown cylinder on the garage entry. The family wants one key for all three. Because the keyways differ, we keep the front Schlage, replace the other two with Schlage deadbolts, and key all three alike. The result is one key on the ring instead of three.
- A rural property near Rancho Cucamonga has a gate padlock, a barn hasp and a house deadbolt, all on different keys, and the gate lock has rusted solid. The deadbolt rekeys easily. The padlock is replaced with a weather-rated shrouded model, and the barn lock is swapped for a keyed-alike one. Three keys become one, and the whole property is handled in a single visit.
- A 2009 Schlage handleset in Downtown Ontario has a few scuffs and a key that disappeared at a party. The latch is tight, the bolt throws a full inch, and the finish is intact. We rekey the deadbolt cylinder, leave the handleset alone, and the owner skips the hassle of matching a discontinued finish. Rekey wins, and the whole visit stays short.
How the visit works
- Tell us what happened and what you want. If you honestly don't know whether you need a rekey or a new lock, say so. We start from your problem, not a product. The inspection at the door decides, and you hear both options before choosing.
- Show you're allowed to decide. Businesses should show they manage the premises, with an ID plus a lease, license or authorization letter. For multi-tenant buildings, we confirm who controls which door before touching anything. It's a few minutes of paperwork that avoids bigger problems later.
- Run the door test on every lock. Then we look past the lock to the door and frame: the strike plate, the screws, the hinges, the weatherstripping and the gap around the edge. A good lock on a weak frame fails where the frame is weakest, so we note anything that needs attention.
- Sort each lock: keep, rekey or replace. We also sort by urgency. A front door with a failing bolt goes first; a basement door nobody uses can wait. If a hybrid plan makes sense, with some locks rekeyed and a few replaced, we show how the keys end up working across the house.
- Do the work and test every key. If a lock fails its test during assembly, such as a rough turn or a bolt that won't retract, we fix it on the spot or swap in another. You hear about any problem right away, and nothing is left for you to discover next week.
- Leave with keys, old parts and a written list. We write down the brand, model, grade and finish of every new lock, along with which locks were rekeyed. That list helps with insurance questions, future parts and the next time someone asks whether a lock was ever changed.
What affects the cost
- Door prep and fit. Mortise hardware lives in a deep pocket. Replacing the whole body can mean cutting a new pocket, so we often prefer to rekey or swap the cylinder instead. When replacement is truly needed, the door work becomes a real part of the estimate.
- Whether the cheaper choice has to be done twice. The lowest quote today isn't always the lowest total. Paying to re-pin a lock that is already failing means paying again when it quits, plus a second visit. We tell you when a rekey would only delay a replacement you'll make anyway.
- Timing, travel and bundling. An urgent call after a break-in or lost key ring is priced as urgent, and a booked appointment is usually easier on the total. If the situation allows, scheduling a few days ahead gives us room to plan the route and bring the exact hardware.
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 Ontario.
Common errors that cost time and money
- Assuming new means better. Many boxed locks are light Grade 3 hardware with thin bolts and plastic parts, and a well-kept older lock can be stronger. Compare grade, bolt material and construction, not just the packaging or the price tag.
- Buying a lock before measuring the door. Backset, bore size and door thickness decide what fits, and a wrong box means returns or drilling into your door. A quick measurement, or a photo sent to us before you shop, saves real aggravation.
- Accepting a phone quote with nobody having seen your locks. Anyone who says replace everything sight unseen is guessing, and so is anyone promising rekeys will cover it all. Ask for an inspection at the door and a written, lock-by-lock list.
Practical tips before you call
- Lubricate before you judge. A sticky lock may only need a puff of graphite or dry PTFE in the keyway, and a squeaky latch may need only a dab at the bolt. Skip oil sprays, which gather grit. If dry lube doesn't cure it, the lock is telling you something.
- Ask whether a replacement lock will be easy to rekey later. Some budget models use unusual cylinders that are costly to re-pin, which turns the next lost key into another full replacement. A mainstream pin tumbler from a major maker keeps your options open.
- Try your key slowly, then try a fresh copy. If both drag, the cylinder is worn and replacement deserves a look. If only your everyday key sticks, that key is worn and new keys may be all you need. The comparison costs nothing and teaches a lot.
- Swap the short screws in the strike plate for 3-inch ones that bite into the framing, whichever way you decide on the lock. It takes minutes, costs little and does more against a kick than most new locks. Start with the front and back doors.

Friday is a full day for us. We begin at 6:30 a.m. and close at 11:30 p.m., the same as every other day, Saturday included. If a lock fails after 11:30 p.m., call us when we reopen at 6:30 a.m., and in the meantime fall back on a neighbor's spare key, a night with family, or a door you can secure from inside.
California's Locksmith Act requires a signed work order when a locksmith opens a residence or commercial property, recording the requester's name, address, phone number, date of birth and ID number. Business and Professions Code §6980.55 has us keep those records for two years, available to BSIS and peace officers on request.

Frequently asked questions
Which is cheaper, rekeying or replacing?
Rekeying is usually cheaper per door because you aren't buying hardware. The answer changes when a lock is failing, since you would pay for the rekey and then for the replacement, or when you have cheap identical locks that cost little to swap. We quote both options for your doors before we start, so you can compare real totals.
Should I replace my lock with a smart lock or just rekey it?
If you like your current lock and want only new keys, rekey it. If you want keypad or app access, a smart deadbolt replaces the hardware, or a retrofit model fits over your existing deadbolt. Either way, the key override cylinder needs rekeying, and not every smart lock suits every door. We help match the model to your door and routine.
What is the difference between rekeying and replacing a lock?
Rekeying changes the pins inside the lock so a different key works and the old one doesn't. The lock itself, including its bolt, latch and finish, stays. Replacing swaps in a new mechanism entirely. Rekeying fixes a key problem; replacement fixes a lock problem. If you have both, such as a lost key and a worn latch, you may need both.
My lock is sticky. Could lubricant solve it instead?
Sometimes. A little graphite or dry PTFE spray in the keyway frees dust-clogged pins, and a dirty key can cause trouble too. If a fresh key also drags, or the latch scrapes or the bolt binds, the problem is wear or alignment. Oil sprays only gather grit, so skip them. If lubricant doesn't cure it, call us before the lock fails completely.
Can I put locks from different brands on one key?
Not by rekeying alone, because Kwikset and Schlage keyways differ and a key for one won't enter the other. To reach one key, we replace the locks that don't match your chosen brand. Within a brand, most locks can share a key. We count each brand first and tell you how many changes the plan takes.
How can I tell a locksmith isn't pushing me toward replacement?
Ask them to show you why. A trustworthy locksmith points to the wobble, the worn plug or the damaged latch, quotes both options, and accepts your choice. Check the license first: Julian's Locksmith holds LCO7891, which you can verify at search.dca.ca.gov. Be cautious of anyone who quotes replacement over the phone without seeing a single lock.
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.
