Rekey Door Locks in Covina: Which Doors, Which Locks
Short answer: You can rekey door locks one door at a time. Rekey only the door a lost key fits, or set a single door to match the key you already carry, as long as that lock shares your key's keyway. In Covina, Julian's Locksmith re-pins, tests and cuts keys right at the door, then checks that the bolt throws cleanly. Call (951) 903-3193.

Rekeying happens at the door, one lock at a time, so your home is never left unsecured while we work. We start with the door you use most, re-pin its cylinder to the new key, test it from both sides and move to the next. Each lock is back in service shortly after it comes apart. Julian's Locksmith brings pins, springs, key blanks and a key machine to your driveway in Covina, so there's no hauling cylinders to a shop and no waiting for keys to be cut somewhere else. Call (951) 903-3193 to rekey door locks on the doors that matter to you.
Rekey Door Locks in Covina: what to expect
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.
What we can do on-site
- Knob and lever entry locks. Levers take far more force than knobs, and on busy doors the spring cassette inside eventually weakens, leaving a lever that droops. Rekeying won't fix that. If a lever on a door you want rekeyed is sagging, we may suggest replacing that one handle and keying it to match, while re-pinning the healthy locks elsewhere in the house.
- Mortise and rim cylinders. Rim cylinders are the flat-faced cylinders on surface-mounted deadlocks, older back doors and many gate locks. Two long screws inside hold the cylinder, and a flat tailpiece reaches into the lock case. They rekey like any pin tumbler cylinder; we just confirm the tailpiece length suits the door's thickness before reinstalling it.
- Security screen and storm doors. A screen door key on its own ring is a daily nuisance. When we rekey door locks behind a security screen, we try to bring the screen onto the same key, so you aren't sorting keys on the porch with groceries in your arms. Where that isn't possible, we can cut its key on a colored blank so it's easy to grab.
- 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.
- Kwikset SmartKey locks. Matching SmartKey locks to your other doors is simple when everything in the house is Kwikset, since they share a keyway. The challenge is a house with SmartKey on some doors and Schlage on others. We can key the Kwikset doors together and replace the odd ones out, or swap hardware so a single key covers everything.
Local factors in Covina
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.
Inland summer heat is hard on doors and locks. Doors facing south or west expand, dark-painted doors get hot enough to make hardware stiff, and old lubricant dries into grit. When we rekey door locks in hot areas, we clean each cylinder thoroughly, use a dry lubricant that won't gum up, and check that the bolt still throws when the door is warm, not just in the cool morning.
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.
Situations this covers
- A typical evening call in Covina: 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.
- Picture a renter in an apartment near Covina Metrolink station 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.
- 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.
- 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.
How the visit works
- Tell us which doors and what's on them. Mention anything unusual: a lock with no working key, a smart lock, a door with a keypad, a slider you've never locked, or a door that's hard to close. Those details change the parts and tools we bring, and they help us plan the order we'll work through your doors.
- 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. 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. While each plug is out, we clean old graphite, dust and grit from the cylinder, check the springs and replace any that are weak or rusted. A rekeyed lock should feel smoother than it did before we arrived. If it doesn't, we keep working on it until it does.
- 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. Pricing follows cylinders, not doors. A front door with a deadbolt and a knob has two; a handleset usually has one; a slider may have none that can be re-pinned. Count keyholes instead of doors and you'll have a fair idea of the size of the job before you even call.
- What kind of hardware each door has. If a door's lock can't be re-pinned, the cost becomes a parts question: a keyed slider lock, a euro cylinder of the right length, or a new handle for a storm door. We quote the part and its price separately, so you can skip it if that door doesn't really need a key.
- 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.
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 Covina.
Common errors that cost time and money
- 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.
- Forgetting the codes and remotes. A rekeyed smart lock still accepts every old keypad code, and the garage still opens for every old remote. If the goal is cutting off someone's access, delete old codes, review app users and reset the garage opener the same day.
- 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.
Practical tips before you call
- 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 Covina, and a Sunday visit works well when several doors are on the list.
- Have the smart lock app open on your phone if a door has one. Rekeying the backup cylinder doesn't touch codes or app users, so the visit is a good moment to delete old codes, check who holds admin access and swap in fresh batteries. We can go through it with you.
- Hand new keys to fewer people than before. A rekey is a reset; if the same five people end up with copies, you've changed the key but not who can get in. For occasional helpers, a smart lock code you can delete later is often better than another metal key.
- 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
Where is the key cylinder on a handleset?
On most handlesets, the keyhole sits in the deadbolt section above the grip, and the thumb latch below opens the door without any key. So a handleset usually needs only one cylinder rekeyed. Some models key both sections, and mortise handlesets use a threaded mortise cylinder. We identify yours before quoting so the price reflects what's actually there.
Can a Kwikset lock be rekeyed to fit my Schlage key?
Not by re-pinning alone. Kwikset and Schlage use different keyway shapes and slightly different pin spacing, so a Kwikset cylinder won't accept a Schlage key. To get one key across mixed brands, we replace the odd cylinders or the locks themselves with hardware in the keyway you're keeping. We'll quote the least expensive route to one key once we see your doors.
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 you rekey the locks on my garage doors?
The walk-through doors are simple: the knob and deadbolt on a garage side door and on the door into the house rekey like any other lock. Overhead garage doors are different. Most run on an opener, and a manual T-handle lock, if yours has one, uses its own cylinder we can check. For openers and keypads, the fix is resetting codes and remotes.
Will rekeying fix a deadbolt that's hard to turn?
Only if the problem is inside the cylinder, such as worn pins or old grime. Most stiff deadbolts are really door problems: a strike plate out of line, a door that has sagged, or a bolt hole drilled too shallow. We check that with the door closed before re-pinning, and we correct the alignment during the same visit when it turns out to be the cause.
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 Covina from your base?
Covina is about 39 miles from our San Bernardino base, roughly 45 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.
