When should a lock be replaced instead of repaired?
A lock earns replacement when the problem is the hardware itself rather than the key or the setup. A cylinder that grinds or sticks even with a fresh key, a latch that no longer catches, a handle that spins loose on its spindle, a deadbolt that has been pried or forced, and a finish worn through to bare metal are all signs the mechanism has aged out. Locks wear in the same places on every door, and once the internal pins and springs give up, patching usually buys only a little time.
Some reasons have nothing to do with damage. A lock that has passed through many tenants, contractors, and house-sitters is a lock that too many people may have had copied. A lockset installed decades ago may still turn smoothly, but it was never designed with today's pick and bump techniques in mind. After a break-in attempt, replacing the damaged hardware is the sensible fix, because a bent latch or a cracked door edge will not hold the way it once did.
Not every problem needs a new lock, and we will tell you when it does not. If the lock is sound and the only worry is who holds keys, rekeying is the lighter-cost route. If one part is failing on an otherwise good lock, a repair may be enough. We explain how to tell the difference further down this page.
What does lock replacement cover?
Lock replacement is a broad label, so here is what we actually mean by it. We remove the old hardware, check the door and frame, and fit new hardware that suits the door, the building, and how you use it. The work falls into a few common groups:
- Front door lock replacement: a new deadbolt, knob, lever, or handleset set that matches your door preparation.
- House lock replacement: back doors, side doors, and garage entry doors, so every exterior door is brought up to the same standard.
- Apartment lock replacement: entry locks and deadbolts for individual units, often between tenants.
- Business lock replacement: storefront, office suite, and back-door hardware, including commercial-grade cylinders.
- Replace broken lock or replace damaged lock: snapped latches, failed cylinders, and hardware damaged in a break-in attempt.
- Security lock upgrade: moving from a basic builder-grade lock to heavier hardware with a stronger strike and longer screws.
How does a lock replacement visit work, step by step?
We keep the process simple and explain each choice before we make it. Because we run both a storefront and mobile vans, we can bring a range of hardware to you rather than guessing over the phone.
- You call (213) 577-1366. We ask what the door is, what is wrong with the lock, and whether the door is currently secure, so we can send the right equipment.
- On arrival, we look at the lock, the door, the strike plate, and the frame. Most failed locks are not the whole story, and a door that has shifted or swollen can ruin a new lock just as fast as the old one.
- We talk through the options in plain terms: what level of hardware fits the door, which finish matches what you have, and whether a smart or keyed option makes sense for how you live.
- We confirm the scope of work and the cost before starting, so there are no surprises mid-job.
- We remove the old hardware, fit the new lock, and adjust the latch, strike, and door alignment so the bolt throws freely without forcing.
- We test the lock from both sides with the door open and closed, hand you the keys, and explain how to operate anything unusual. We also tell you what to do with any old keys.

Call (213) 577-1366Replace, rekey, or repair: which one do you need?
These three jobs get mixed up often, and choosing the right one can save you real money. A rekey changes the internal pins so that old keys no longer work, while the lock itself stays in place. It suits a sound lock where the concern is key control, such as a recent move or a lost key. If that sounds like your situation, our lock rekeying service is usually the more economical route.
A repair fixes a single failing part, like a loose handle, a sticking latch, or a worn spring. If the rest of the lock is in good shape, lock repair may be all you need. We do not push a full replacement when a small fix will hold.
Replacement is the right call when the lock is physically damaged, badly worn, missing parts that are hard to source, or too basic for the door it protects. It is also the right call when you simply want a different type of lock, such as moving from a knob to a deadbolt or a keypad. If you are adding a deadbolt where none exists, that is a separate job we cover under deadbolt installation. Often the honest answer is a mix, and we will say so when we see the door.
What affects the cost of lock replacement in El Monte?
We do not quote prices on a web page because the same job can look very different from one door to the next. What we can do is explain exactly what moves the cost, so you know what you are paying for:
- The type of lock: a standard keyed knob, a heavier deadbolt, a handleset, a smart lock, and a commercial-grade cylinder all sit at very different cost levels.
- The grade and brand of hardware: sturdier construction, better materials, and tighter tolerances cost more but last longer under daily use.
- How many locks: replacing one front door lock is a different job from changing every exterior door, though doing several in one visit usually makes the work more efficient.
- The condition of the door and frame: a warped door, a split jamb, or an enlarged bore hole may need repair before the new lock will sit right.
- Whether keys need to match: several doors keyed alike takes a little more planning than separate keys.
- Time of day: after-hours, weekend, and holiday calls take more of our time and resources than a daytime appointment.
- Location and travel: our storefront is in Westwood, so service in El Monte involves driving time that we take into account.

Call (213) 577-1366How do you choose the right new lock for a security upgrade?
A security lock upgrade is not just buying the most expensive box on the shelf. A lock is only as strong as the weakest part of the door setup, so we look at the whole assembly. A strong deadbolt held in place by short screws in a thin jamb will still give way under a hard kick. Longer strike screws that reach the framing, a reinforced strike plate, and a solid-core or well-supported door often matter as much as the lock body.
Hardware grade matters too. Lock makers rate residential hardware by durability and strength, and the heavier grades are made to take more abuse and more years of daily use. For an exterior door on a rental or a business, that extra durability usually pays for itself. For a low-risk interior door, a lighter lock is perfectly reasonable.
If you want keyless entry, smart lock installation is worth considering. Smart locks suit rentals and shared access well, but they need a door that closes squarely and a handing and bolt prep that match. We will tell you plainly if your door is not ready for one. For anyone who wants more resistance to picking and unauthorized key copying, we can also talk through higher-security cylinders.
Apartment lock replacement and rental turnover
Renters make up a large share of El Monte households, and that changes how lock replacement works. Tenants usually need permission before changing a lock, and the law and your lease both matter here, so check yours first. Where you do have the right to make a change, we can usually replace a worn or broken lock the same way we would for a homeowner, and we will leave you with the original hardware if the lease calls for it.
For landlords and property managers, replacement often happens between tenants, or after a lock has been damaged or forced. Handling a whole building the same way, with consistent hardware and clear key records, saves headaches later. If you manage several units, our locksmith for landlords service explains how we handle turnover work, and we are glad to talk through a plan that fits your properties.
Small apartment complexes and backyard accessory units are common in El Monte. Those smaller doors often get overlooked, with thin hollow-core doors and light-duty locks that are easy to defeat. A replacement visit is a good chance to check them.
Business lock replacement and security upgrades
Commercial doors work harder than house doors. A storefront lock may cycle hundreds of times a day, and an old one will start to bind, stick, or fail without warning, usually at the worst time. Business lock replacement means choosing hardware rated for that traffic, fitting it to the door, and making sure it works with any closers, panic hardware, or access systems already in place.
We handle storefront doors, office suites, back doors, and rolling or sliding doors. For anything involving the wider door hardware package, see our commercial locksmith page. A business security upgrade can also mean tightening up who holds keys, replacing a lock after an employee departure, or swapping an old lock that is no longer easy to source.
For businesses we aim to work around your operating hours when we can, so the door is secure when you close up. If a lock fails and the door will not lock at all, call us any hour and we will help secure the premises first.

Call (213) 577-1366What does lock replacement look like across El Monte?
El Monte covers ZIP codes 91731 and 91732, and the housing and buildings are mixed enough that lock replacement looks different from one area to the next. Much of the housing is postwar bungalows and small ranch homes, and original mid-century locksets are still widespread on that older stock. Those locks have done decades of work, and many of them are good candidates for replacement simply because the springs and cylinders are tired.
In Five Points, a common job is a security screen door and a deadbolt on a postwar bungalow. Security screens and window bars are a common retrofit on denser blocks, and they make a difference to how hardware needs to be fitted. A new deadbolt has to clear the screen door frame, and the handle on the inner door has to open without scraping. We check that fit before we install, and not afterward.
Heat is the other local factor. El Monte sits in the flat San Gabriel Valley basin with hot, dry summers and little coastal cooling. Wood doors and frames expand in the heat, and a lock that worked in spring can start to bind by August. Before we replace a lock for that reason, we check whether the door is rubbing the frame, because a new lock on a swollen door will just wear out sooner.
Downtown near the Valley Mall pedestrian district and over in the Flair Park business district, the work leans toward storefronts and office suites. The Northwest Industrial District brings warehouse and roll-up door hardware. Near El Monte Station, apartment lock issues come up often, and a stuck or damaged lock is something we can handle at any hour. If you are locked out first, our emergency locksmith service is the place to start, and we can sort out the replacement once you are back inside.
Why call Wilshire Lock & Key for lock replacement?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, El Monte among them. We run a storefront at 10740 Wilshire Blvd in Westwood along with mobile service vans, so we are a real local company and not a call center. When you phone (213) 577-1366, the line is answered 24 hours a day, 7 days a week, year-round.
We are one company, not a dispatch service passing your call to whoever is available. The person who sends the van is part of the same team that does the work, and David, the owner and lead technician, oversees the work we do. That means someone is accountable for the result.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that number before they start work. We are in the process of adding our license number to this site. If you want to confirm anything about us before booking, call and ask. We would rather answer questions up front than have you wonder.
If you would like to talk through a replacement before booking, you can also reach us through our contact page.
Frequently asked questions
How do I know if I need a new lock or just a repair?
If the lock is physically damaged, worn badly, or failing in more than one way, replacement usually makes more sense. If one part is loose or sticking and the rest is sound, a repair may be enough. We look at the lock and tell you honestly which one it is.
Can you replace a lock the same day I call?
We answer the phone 24 hours a day, 7 days a week, and we work to get to you as soon as possible. Availability depends on what is going on that day and on what hardware the job needs, so we confirm timing when you call (213) 577-1366 rather than promising it up front.
Will the new lock work with my existing door?
Usually yes, since most doors follow standard bore and latch sizes. Older doors, security screen doors, and doors that have swollen in the heat can need extra adjustment. We check the fit before we install so the lock sits correctly and operates smoothly.
Is it cheaper to rekey than to replace?
Rekeying is usually the more economical route when the lock itself is in good condition and you only want old keys to stop working. If the lock is damaged or worn out, a rekey will not fix that, so replacement is the better use of money.
Can I change the lock on my rental apartment?
That depends on your lease and on California law, so check your lease and talk to your landlord first. Where a change is allowed, we can replace a broken or worn lock and keep the original hardware if you need it back for move-out.
Do you replace locks on businesses and storefronts?
Yes. We replace locks on storefronts, office suites, and back doors, and we can fit hardware rated for heavier commercial traffic. For work on the wider door hardware, we handle that on a separate visit if needed.
Should I get a smart lock when I replace my front door lock?
It depends on how you live. Smart locks suit rentals, shared access, and people who dislike carrying keys, but they need a door that closes squarely and is prepped correctly. We will tell you plainly whether your door is ready for one.
How do I make sure the locksmith I hire is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for that number before work begins and check it. A legitimate company will give it to you without hesitation.
