West Covina, Los Angeles County
Change Locks in West Covina: Rekey or Replace Every Door
Short answer: Changing locks usually takes one visit. We count every keyed door, including the garage entry, side gate and security screen door, decide door by door whether a rekey or new hardware makes sense, and quote it. Then we do the work and test each key with the door shut. You leave with fresh keys and a clear list of who holds them. Call (951) 903-3193.

Deciding to change locks in West Covina usually starts with an uneasy question: who else might still have a key? Maybe the sellers handed over two keys, but the cleaners, the pool service and a former tenant had more. Maybe a roommate left on bad terms. Julian's Locksmith answers that question by making the old keys worthless, either by rekeying the cylinders you have or by installing new hardware where yours is tired. We come to you, check every keyed door, and tell you plainly which locks need replacing and which only need new pins. You approve the quote before we start, and we verify that you live at or own the property first.
People ask us to change locks when they could rekey them, and the reverse, so settle that decision first. Rekeying keeps your hardware and changes the key. Changing locks means swapping the hardware itself, and it makes sense when the old locks are worn or damaged, lack a deadbolt, don't match the style you want, or when you're moving to a keypad or smart lock. Homeowners in West Covina commonly change locks after a break-in damaged the latch, when a 1950s knob finally fails, or when the finish has cooked off a south-facing front door. We remove the old hardware, check the door prep, fit new locks and key them alike or to your preference. Tenants have rules to follow. A lease generally requires the landlord's consent to change a lock, and Civil Code §1941.3 obliges landlords to keep working deadbolts on main entry doors. Safety is the exception: under Civil Code §1941.5 and §1941.6, a landlord must change the locks within 24 hours of a tenant's written request in certain situations involving a protective order or similar documentation. We can do the work on the landlord's behalf when the landlord authorizes it. Before touching a lock we confirm your tie to the home, and we quote first.
What to know first in West Covina
There are three ways to change locks, and choosing among them depends mostly on the condition of what's already on your doors. Rekeying keeps the hardware and swaps the pin stack inside each cylinder, so the old key no longer reaches the shear line. It's the right call for sound locks you like. Replacing only the cylinder works on mortise locks, rim locks and Euro-profile multipoint doors, where the cylinder is a separate part. Replacing the whole lockset makes sense when the latch sticks, the knob wobbles, the finish has peeled in the sun, or the lock is an ungraded bargain model. In West Covina, many homes end up with a mix: re-pinned deadbolts on the front and garage entry, new levers on a back door that has worn out, and a matching cylinder added to the security screen door. We explain each recommendation door by door and price the options so you can choose. Nothing gets replaced just because we happen to have stock on the truck.
How we can help in West Covina
- Smart lock swaps and code resets. Retrofit smart locks such as the August keep your existing exterior cylinder, which means old keys still open the door. If you add one, pair it with a rekey. We also flag hinge-side drag and warped doors, because a motorized bolt that binds will drain batteries fast in the summer heat around West Covina.
- Restricted keyways and high-security cylinders. If you change locks because keys keep getting copied, a restricted keyway addresses the cause. Patented systems from Medeco, Mul-T-Lock and ASSA Abloy use blanks that hardware stores can't cut, and duplicates require the owner's card or signature. We can fit these cylinders into many existing deadbolts and handlesets.
- Keying every door alike. Keying alike is convenient, but sometimes you want exceptions: a side gate key for the gardener that doesn't open the house, or a workshop key only you carry. We can set those up as separate keys or, on compatible hardware, build a simple master arrangement so your key opens everything while helpers' keys open only their areas.
- Urgent safety lock changes. California gives protected tenants specific lock rights. Under Civil Code 1941.5 and 1941.6, the landlord must change the locks within 24 hours of the tenant's written request in certain situations involving a protective order or similar documentation. If the landlord doesn't, the tenant may have the locks changed and must then give the landlord a key. We can work for either side.
- Older doors, mortise locks and unusual prep. Some older doors were bored at 1-1/2 inches or set at a 5-inch backset, and modern locks won't fit without help. We use conversion plates, enlarge bores carefully, or source compatible hardware. When a door is too damaged or thin to hold a new lock securely, we say so and suggest a door or carpentry repair first.
How West Covina shapes the job
Inland heat is hard on locks. Doors expand, strikes misalign, and dark finishes on sun-facing doors fade or peel. When you change locks in West Covina, choose finishes that tolerate direct sun and keypad locks rated for outdoor heat, and expect batteries to need replacing more often in summer. We set strikes with enough tolerance that the deadbolt still throws easily on the hottest afternoons.
Long commutes mean long empty hours at home, and a lock change for commuters should account for that. In West Covina, many households add a smart deadbolt that reports its status, so you can confirm the door is locked from the office. We can schedule a lock change early, starting at 6:30 a.m. every day of the week, so you don't lose a full day of work.
Foothill homes face wind-driven dust and, in fire season, the possibility of evacuation. If you change locks on a canyon or foothill property near West Covina, keep a spare key or code where a trusted neighbor can reach it, so someone can check the house or get pets out during an evacuation. Dry lubricant matters here too, because Santa Ana winds push grit into exterior cylinders.
Common situations
Imagine an apartment resident near the Civic Center with a restraining order against a former partner who still has a key. She gives her landlord a copy of the order and asks for the lock to be changed. The landlord authorizes us. We meet her at the door, verify her ID against the lease, confirm the landlord's okay, and rekey or replace the deadbolt and knob so the former partner's key is useless. She receives new keys and a note of what was done.
- Consider a home off I-10 where someone kicked in the back door while the family was at work. The deadbolt is intact, but the jamb split along the strike. After the police report is filed, we'd assess whether the jamb needs a carpenter, install a heavy strike with 3-inch screws once the frame is sound, and rekey every lock in case a spare key was taken from a kitchen drawer.
- A typical call: a roommate in a West Covina rental moves out after an argument and keeps a key. The remaining tenant contacts the property manager, who agrees to a rekey as long as the office receives a copy. We'd check the lease and ID, re-pin the entry deadbolt and handle, cut keys for each remaining tenant plus one for the manager, and note who received them.
- For instance, a newer West Covina home sells with a Wi-Fi deadbolt that the sellers still control from their phones. They're cooperative but slow to remove themselves from the app. We'd factory-reset the lock, delete stored codes, enroll the new owner as administrator, connect it to the new owner's network, and rekey the override cylinder, because the key the sellers kept would otherwise still open the door.
Step by step with Julian's Locksmith
- Tell us the reason and count the doors. Call (951) 903-3193 and tell us why you want to change locks: move-in, lost keys, break-in, safety or turnover. Then count keyed doors, including the garage entry, security screen door and gates. That list, plus the brands printed on the locks, lets us load the right pins and hardware.
- Verify residence or ownership. Executors, trustees and property managers can authorize a lock change too, with the right paperwork: letters testamentary, a trust document, or a management agreement or work order. If the papers are somewhere you can't reach, we'll talk through what else might work before anyone touches a lock.
- Inspect each lock and choose rekey or replace. This is also when we talk about upgrades without pressure: a reinforced strike on the front door, a matching cylinder for the security screen door, or a keypad deadbolt for a rental. Each is optional and priced separately, so you can change locks on a tight budget and add the rest later.
- Re-pin or install the hardware. Strike work happens at this stage too. We chisel or file the strike pocket so the bolt enters cleanly, drive longer screws into the framing, and adjust the latch strike so the door closes without a shoulder push. A lock that latches easily is a lock that actually gets used.
- Test every key on every door. Testing includes the locks you won't use daily: the garage entry, side gate and screen door. We also turn each old key in each re-pinned cylinder to confirm it no longer operates. If you left a spare with a neighbor or in a car, bring it so we can test that one as well.
- Hand over keys and records. You get the new keys, a count of how many were cut, and an itemized invoice. We suggest writing down who receives each copy. If you rent, the landlord or manager typically gets one under your lease. Old keys can go in the trash; they no longer fit anything on the property.
Pricing factors
- Rekey versus new hardware. Rekeying usually costs less per door because the expensive parts stay put. It isn't always the bargain it looks like, though. If a knob already wobbles or a latch sticks every summer, paying to re-pin it can mean paying again soon to replace it. We'll tell you when a lock isn't worth rekeying.
- Hardware grade, brand and finish. Smart locks and high-security cylinders sit at the top of the hardware range. A keypad deadbolt adds setup and app pairing time; a patented cylinder adds a controlled blank and key registration. Both buy something real, easy code changes or tight key control, so decide which problem you're actually trying to solve.
- Door condition and prep work. A door in good shape makes a lock change routine. A door with stripped screw holes, a split edge, a 1-1/2 inch bore or a strike that no longer lines up adds time and parts. We price prep work as its own line so you can see what's lock work and what's repair.

Common errors that cost time and money
- Changing locks on a rental without telling the landlord. Even with a good reason, it can breach the lease and block emergency access or repairs. Ask in writing, provide a key, and keep a copy of the exchange. Safety situations under Civil Code 1941.5 and 1941.6 have their own rules and deadlines.
- Hiring from an ad with a suspiciously low lock-change price. Some unlicensed operators quote one figure, drill locks that could have been rekeyed, then charge far more. In California, a locksmith company must hold a BSIS license, so ask for the number and check it at search.dca.ca.gov before any work starts.
- Assuming a smart lock means no rekey is needed. Retrofit models replace only the inside half and keep the old exterior cylinder, and full smart deadbolts still have a keyed override. If an old key turns that cylinder, the door opens no matter how many codes you delete from the app.
Advice before you book
- Use dry lubricant on exterior locks in dusty inland areas. Graphite or a PTFE-based dry spray keeps pins moving without attracting grit. Oily sprays feel smooth for a week, then collect dust blown in by Santa Ana winds and gum up the cylinder. A puff in the keyway twice a year is plenty for most residential locks.
- Buying a house in West Covina that has a smart lock? Ask your agent to put the admin handover on the sellers' move-out list. Even so, factory-reset the lock after closing, check the app for shared users and any connected hub, and change the Wi-Fi password the sellers may have left on the router.
- Test your deadbolt with the door closed. Turn the thumbturn slowly; if you feel it drag, or you have to push or lift the door, the strike is out of line and the bolt may not be fully extended. A partly thrown bolt is far weaker. Mention it when you call so we can realign it during the lock change.
- Planning a lock change for a rental or vacation home in West Covina? Consider a keypad deadbolt with a keyed backup on the main entry. Guests and cleaners each get their own code, and removing one takes seconds. Keep the mechanical keys few and accounted for, because the keypad is only as secure as its override cylinder.

Frequently asked questions
My ex has a key. Can I change the locks?
If you're the only owner, or the only tenant on the lease with landlord consent, yes, after verification. If you both own the home or are both on the lease, a lock change doesn't erase the other person's legal rights, and excluding them can create legal trouble. A protective order changes that picture. Talk with an attorney or legal aid if you're unsure, then call us.
Does changing my locks stop old garage door remotes?
No. Garage openers are a separate system. After you change locks, clear the opener's memory using the learn button on the motor unit, reprogram your own remotes and car buttons, and change the exterior keypad code. If your garage connects to the house, key the door between them with the rest, because anyone with a working old remote can reach it.
Should I rekey or change my locks?
Rekey if your locks work smoothly, you like how they look, and the only problem is that someone else might have a key. Replace if a lock is worn, damaged, ungraded, the wrong brand to match your other locks, or you want features such as a keypad or a high-security cylinder. Many West Covina homes get a mix of both, and we quote each door separately.
Will you install locks I bought myself?
Yes. We install customer-supplied hardware and rekey it to your house key so you don't end up with a separate key for one door. Before buying, check that it's rated for exterior use, fits your door thickness and backset, and matches your existing bore. Have the box and every part at the door; strikes and screws go missing surprisingly often.
Do I need to change locks after buying a house?
You should, and it's one of the first things we recommend after closing. The sellers, their relatives, past contractors, cleaners and showing agents may all have had keys, and nobody can account for every copy. A rekey of sound hardware is usually enough. Add a factory reset for any smart lock and clear the garage opener's memory while you're at it.
Can a landlord change the locks to evict a tenant?
No. California law, including Civil Code 789.3, prohibits a landlord from changing locks or otherwise cutting off a tenant's access to force them out. Eviction requires a court process, and a sheriff carries out any lockout after a judgment. That's why we verify who is asking for a rental lock change and won't do one that would shut out a lawful occupant.
How far is West Covina from your base?
West Covina is about 42 miles from our San Bernardino base, roughly 47 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.
