Does your lock need to be replaced, or just fixed?
Most people who call about lock replacement already know something is wrong. The key drags going in. The latch sticks. The deadbolt turns halfway and stops. Or the lock was damaged after a break-in attempt, and you want it gone. Sometimes replacement is the right answer. Sometimes it isn't, and we'll tell you so.
A lock is worth replacing when the internal parts are worn past the point where adjustment helps, when the body or faceplate is bent or cracked, when the finish has failed and the mechanism is corroding, or when the hardware is simply too basic for what the door protects. It is also worth replacing when you can't account for every key ever cut for it and a fresh set of pins isn't enough for your peace of mind.
Sometimes the lock is fine and the trouble is somewhere else: a door that has shifted in its frame, a strike plate a little out of line, a latch that needs cleaning. In those cases a lock repair costs less and keeps good hardware in service. If the only concern is who holds keys, a rekey changes the internal pinning and leaves the hardware in place. We would rather fit the fix to the problem than sell you a new lock you don't need.
How does lock replacement work, step by step?
Replacement is a straightforward job when it is done carefully, and the care is where the quality shows. Here is how we run it at a La Puente home or business.
- You call (213) 577-1366, day or night. Tell us what the lock is doing, what kind of door it is on, and whether the door still closes and latches. A few plain questions up front let us bring the right hardware.
- We confirm you have the authority to change the lock. At a home that means you live there or own it. At a rental or business, it means you are the tenant, manager, or owner with a say over the door.
- We look at the door and the existing lock. We check the bore holes, the backset, the edge thickness, the strike plate, and the condition of the frame. A new lock is only as good as the door it sits in.
- We explain the options in plain terms: what we'd replace, what we'd leave, and what changes between a basic grade and a stronger one. You decide before any work begins.
- We remove the old hardware, fit the new lock, and set the strike so the bolt throws fully into solid wood or metal rather than just a thin frame edge.
- We test it with the door open and closed, from inside and outside, with every key. You get the keys, and we point out anything about the door itself that could shorten the life of the new lock.

Call (213) 577-1366What kinds of lock replacement do we handle in La Puente?
The word replacement covers a lot of ground. Here is how the requests usually break down.
- Front door lock replacement: knob sets, lever handles, and deadbolts on the main entry, including worn or damaged sets that have started to fail.
- House lock replacement: all the exterior doors at once, so every entry matches and you work from one key. This is common after buying a home or after a break-in.
- Residential lock replacement for secondary doors: back doors, side doors, and the garage service door.
- Apartment lock replacement: entry locks for tenants and for property managers who need to turn units over. Landlords with several doors can look at our page for locksmith services for landlords.
- Replace damaged lock or replace broken lock: the lock that was forced, snapped, jammed, or vandalized and can't be trusted to secure the door anymore.
- Security lock upgrade: moving from a basic builder-grade lock to hardware that resists picking, drilling, and forced entry. A dedicated deadbolt installation is often the first step.
- Commercial lock replacement and business lock replacement: storefront doors, back-of-house doors, and office entries, where the lock gets heavy daily use.
- Business security upgrade: swapping tired hardware for sturdier commercial-grade locks as part of a wider tightening-up of the building.
How much does lock replacement cost in La Puente?
We don't quote prices on a web page, because the honest number depends on your door. What we can do is tell you exactly what moves the cost up or down, so there are no surprises when we give you a figure on the phone or at the door.
The biggest factor is the hardware itself. A basic residential knob set and a high-security deadbolt are very different products, built to different standards. Lock grades run from Grade 3 for light residential duty up to Grade 1 for heavy commercial use, and the higher the grade, the more the hardware generally costs.
The second factor is how many locks you are replacing. Doing every exterior door in one visit is usually the more economical route compared with coming back door by door, since the diagnosis, setup, and travel are done once.
Third is the condition of the door. If the bore holes are the standard size and the edge is sound, the swap is quick. If a previous lock was forced and the wood around it is split, or the holes were drilled badly years ago, there is extra work to make the door hold the new lock properly.
Fourth is timing. A scheduled replacement during the day is simpler than an after-midnight call to secure a door that was just damaged. We are here at any hour, and we will explain how the time of the call affects the work before you agree to anything.
Finally, there is whether you want keyed hardware matched across doors, extra keys cut, or a smart lock instead of a conventional one. None of these is complicated, but each adds hardware and labor. Ask us for the lighter-cost option and we'll tell you what that looks like and where it falls short.

Call (213) 577-1366What does lock replacement look like on La Puente homes and storefronts?
La Puente's housing is mostly single-story stucco tract homes from the 1950s, built during the area's rapid postwar subdivision, on modest lots with detached garages. That shapes the lock work we see. On the 1950s tract streets around the La Puente Park area, a typical replacement call is for an original or long-serving lockset that has simply worn out: loose handles, keys that stick, a latch that no longer catches cleanly. Replacing worn original locksets on postwar homes is some of the most common work in the city, and it is a good time to upgrade the entry to a proper deadbolt while the door is open.
Owner occupancy is high and many households are multigenerational, which means a lot of people may carry keys to one front door. That is a practical reason to replace rather than keep patching: a fresh lock and a clean set of keys lets the household decide who has access. Security screen doors are also a common retrofit on these homes, so when we replace a main door lock, we look at how the screen door and the entry door work together and make sure the handle and key clearance aren't fighting each other.
The climate matters, too. The eastern San Gabriel Valley has hot, dry summers and mild winters with no coastal salt air, so corrosion is rarely the issue. The practical effect is seasonal expansion of wood doors on postwar homes. A door that swells in summer heat can rub, push the latch out of alignment, and make a good lock feel broken. We check the fit before blaming the hardware, and we tell you if the door itself needs attention. If you are locked out in the meantime, our house lockout page explains how we get you back inside.
On the business side, we handle storefront lock replacement in the Old Town La Puente business district, where street-facing doors take daily use, and commercial lock work along the Hacienda Boulevard corridor and the Amar Road corridor. Apartment stock in La Puente is limited and concentrated near those major corridors, so apartment lock replacement tends to be unit-door work for managers and tenants nearby. We also get calls from the Valinda and Bassett border areas, just outside city limits.
Whether your address falls in ZIP code 91744 or 91746, the process is the same: a phone call, a look at the door, a clear explanation, and a lock that fits. For storefronts that need repairs rather than a full swap, see our storefront lock repair page.

Call (213) 577-1366When is a lock replacement really a security upgrade?
Sometimes you are not fixing a failure. You are fixing a weakness. Builder-grade locks on older homes are often thin on the parts that matter: short screws, a light strike plate, a cylinder that can be picked or bumped without much trouble. A security lock upgrade deals with those weak points.
The meaningful improvements are not always the flashy ones. A deadbolt with a one-inch throw into a reinforced strike, long screws that reach the framing, and a cylinder rated to resist picking and drilling will do more than an expensive-looking handle set. For people who want to go further, our high-security locks page covers restricted keyways and tougher cylinders.
For businesses, a business security upgrade usually means looking at the whole door: the lock, the strike, the hinges, and the frame. A strong lock in a weak frame is a weak door. We'll look at the full picture and tell you where the money does the most good, even if that means spending less than you expected.
Why call Wilshire Lock & Key?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, La Puente among them. We run a storefront at 10740 Wilshire Blvd in Westwood alongside mobile service vans, so there is a real shop behind the van that shows up. La Puente is roughly 29 miles from our base, and we say that plainly rather than pretend we're around the corner.
When you call (213) 577-1366, you reach us, not a national call center that dispatches the job to whoever is closest. It is one company from the phone call to the finished door, with no middleman marking up the work. David, the owner and lead technician, oversees how we do the work and what we recommend.
The phone is answered 24 hours a day, 7 days a week, all year. A broken lock doesn't wait for business hours, and a door that won't secure at midnight is as urgent as it gets. For related jobs, our pages on mobile locksmith service and La Puente locksmith services show what else we can do at the same visit.
How do you check any locksmith before they touch your door?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for that license number before work begins, and look it up on the state's lookup tool if you want to confirm it. A legitimate company will give it to you without hesitation.
Other signs worth watching: a company that won't give a business name when it answers the phone, a quote that changes dramatically once someone is at your door, or a technician who wants to drill a lock that could be picked or rekeyed. Ask what the work includes, what the new lock is, and whether the keys are included. You are allowed to ask questions and to say no.
Frequently asked questions
Can you replace a lock the same day I call?
We answer the phone around the clock, and we do our best to bring common hardware to the job. Whether we can finish in one visit depends on your door and the hardware you want. Unusual sizes, specialty locks, or a damaged door may need a second step. We'll tell you up front on the phone.
Should I replace my lock or just rekey it?
If the lock works well and you only want to cancel old keys, a rekey is usually the more economical route. Replacement makes sense when the lock is worn, damaged, or too weak for the door. Many La Puente homes with original 1950s-era hardware benefit from a replacement, but we'll look at your lock before recommending it. Our lock rekey page explains the other option.
Do I need to replace all my locks when I move into a house?
You can't know who holds copies of the old keys, so changing the locks is a sound move. Whether that is a rekey or a full replacement depends on the condition of the hardware. If the locks are old or worn, replacing them while you're at it can save a second visit later.
My wood front door sticks in summer. Will a new lock fix that?
Probably not. Wood doors on older tract homes can swell in hot weather and rub the frame, which pushes the latch out of line. We check the door fit first. Sometimes a small adjustment to the strike or hinges solves it, and sometimes the door needs work that isn't locksmith work. We'll say which.
Can you replace locks for a business in the Old Town area or along Hacienda Boulevard?
Yes. We do commercial lock replacement for storefronts, offices, and back doors, including in Old Town La Puente and along the Hacienda Boulevard and Amar Road corridors. Commercial doors take heavier use, so we usually discuss hardware grade and the condition of the door frame before choosing a lock.
I rent my apartment. Can I have the lock replaced?
Check your lease and talk with your landlord or manager first, because the lock belongs to the property. If the manager authorizes it, we can do the work. Property managers who handle several doors can reach us at (213) 577-1366 to talk through a plan.
Will you need proof that I live here or own the business?
We ask a few questions and may ask for identification or proof of your connection to the property. It is a standard step, and it protects you. A locksmith who will change any lock for anyone who asks is a risk to everyone's security.
Can I switch to a smart lock when I replace my old one?
In many cases, yes. It depends on the door, the strike, and whether you want a smart lock as your only lock or alongside a conventional deadbolt. Our smart lock installation page covers it. We can talk through the tradeoffs when you call.
