Do you actually need a new lock, or just a repair?
Plenty of people call us asking for door lock replacement when the lock only needs adjusting, and a few call asking for a repair when the lock has really reached the end of its life. Sorting out which one you have is the first thing we do, because it decides how much work and how much hardware is involved.
A lock is usually worth replacing when the internal parts are worn past the point where adjusting helps. A key that has to be jiggled, lifted, or forced every morning is the classic sign. So is a latch that no longer catches the strike plate cleanly, a cylinder that spins freely, or a handle that has gone loose on its spindle. Cheap hardware that has been rekeyed or repaired a few times often reaches a point where the next fix will not hold.
Other times, replacement is the right call even though the lock still works. If someone you did not choose has a key, if you have lost track of how many copies are out there, or if the lockset is so old that parts are no longer made, a new lock is cleaner than patching the old one. And if a break-in attempt bent the latch, cracked the door edge, or damaged the cylinder, you want to replace the broken lock rather than trust something that has already been stressed.
If the lock is sound and the only concern is who holds keys, we will tell you plainly that rekeying the existing lock is usually the more economical route. We would rather do the smaller job honestly than sell you hardware you do not need.
How does lock replacement work, step by step?
Here is how a typical residential lock replacement goes when you call us. The details change with the door and the hardware, but the order stays about the same.
- You call (213) 577-1366. A person answers at any hour, and we ask what the lock is doing, what kind of door it is on, and whether the door is currently secure.
- We figure out whether this is a replace job, a repair, or a rekey. If it is urgent, such as a door that will not latch or a lock that was damaged in a break-in, we treat securing the opening first.
- A technician comes to you in a mobile van from our Westwood base. We look at the lock, the door thickness, the bore holes, the strike plate, and the condition of the wood or metal around the hardware.
- We go over the options with you: matching the existing finish and style, stepping up to a sturdier grade, or moving to a different style altogether. You decide before any work is done.
- We remove the old hardware, check the door prep, and fit the new lock. If the holes are slightly off or the strike plate is worn, we correct that so the new lock does not inherit the old problem.
- We test the lock with the door open and closed, from inside and out, and confirm every key works smoothly. Then we hand over the keys and explain how to care for the lock.

Call (213) 577-1366Front door and house lock replacement: what we install
The front door is where most house lock replacement calls begin, and it is also where the choices matter most. A front door lock usually means two parts working together: a knob or lever with a latch, and a separate deadbolt. Sometimes both need replacing, and sometimes only one has failed. We look at the pair as a system, not as isolated pieces.
For residential lock replacement, the common categories are standard keyed entry sets, deadbolts, lever handles, and keypad or smart options. Each has its place. A straightforward keyed set in a solid grade does the job for many homes. A stronger deadbolt makes sense where the door and frame can support it. If you are interested in a deadbolt installed or upgraded, that is a related job we handle separately, but it often happens in the same visit as a lockset swap.
If you want a real security lock upgrade rather than a like-for-like swap, we can talk through high-security lock options. These offer better pick resistance and key control, but they only help when the door, frame, and strike plate are strong enough to match. A very good lock in a weak frame is a small improvement at best, and we will say so.
- Worn or sticking keyed entry sets on front and back doors
- Loose, cracked, or broken handles and levers
- Deadbolts that no longer throw smoothly into the frame
- Locks damaged during an attempted break-in
- Mismatched hardware left behind by previous owners or tenants
- Outdated locksets you want to modernize or secure better
What about apartment lock replacement?
Apartment lock replacement has its own wrinkles. In a condo or apartment, the door and frame might belong to the building, the lock may need to fit a specific style, and the property manager or HOA may have rules about what can be installed. Before we swap anything, it helps to know whether you own the unit, rent it, or manage it for someone else.
Tenants often call when a previous resident never returned all keys, after a roommate leaves on bad terms, or after a lockout that exposed how worn the hardware had become. If you are a tenant, check your lease and talk to your landlord about who handles lock changes. If you are the owner or manager, we can swap the hardware and keep records of which keys go with which unit. Property owners with several doors can also look at our locksmith service for landlords, which covers turnovers and multi-unit work.
If you are stuck outside a unit right now, that is a different job from replacement, so see apartment lockout help. Once you are back inside, we can look at whether the lock that failed should be replaced.

Call (213) 577-1366Business lock replacement and commercial lock replacement
Commercial lock replacement is a different animal from a house job. Storefront doors get opened and closed many times a day, take more abuse, and often have hardware that has to meet fire and egress requirements. A lock that works on a bedroom door might fail within weeks on a busy shop entrance.
When we handle business lock replacement, we look at how the door is used. How many people go through it? Does it need to be locked from the outside at night but free to exit from inside at all times? Are there multiple employees who need keys, and who should not have them anymore? The answers determine whether we recommend a heavy-duty cylindrical lock, a mortise lock, an exit device, or something else.
A business security upgrade does not always mean replacing everything. Sometimes it means a better cylinder, a reinforced strike, or a door closer that actually lets the door latch. We can handle that side through our commercial locksmith work, and we will tell you when a smaller fix will do. Larger changes such as access control, panic hardware, or master key systems are their own projects, and we scope them separately instead of folding them into a basic lock swap.
How much does lock replacement cost in Montebello?
We do not quote numbers on a web page, because the honest answer depends on the door in front of us. What we can do is tell you exactly what moves the cost up or down, so you can judge any quote you get from anyone.
The biggest factor is the hardware itself. A basic entry set, a heavier deadbolt, a high-security cylinder, and a smart lock sit at very different levels, and the grade of the lock matters as much as the brand. Two locks that look similar on a shelf can be built very differently inside.
The second factor is the condition of the door. If the bore holes are the right size and the strike plate is solid, installation is simple. If the door has swelled, warped, or been cut for an older lock, we may need to correct the prep, and that adds labor. Older wood doors and doors that have been replaced locks several times are the usual culprits.
Other factors include how many locks you need replaced, whether you want them keyed alike so one key works every door, and whether the work is urgent or scheduled. Late-night and holiday calls take a technician out of their regular rest, and that can affect the total. Distance matters a little, too, since Montebello is roughly 21 miles from our Westwood storefront.
Our practice is to explain the options and the total before we begin the work. If a lighter-cost option will solve the problem safely, we tell you. If a cheaper lock would fail again in a year, we tell you that as well.

Call (213) 577-1366Why call Wilshire Lock & Key for a lock replacement?
We have been in business since 1987, and that history shows up in small ways: we recognize old hardware on sight, we know which locks tend to wear out in which way, and we have seen most of the strange door problems that turn up in older homes.
We run a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans that come to you. There is no call center passing your job to whichever subcontractor happens to be free. The company that answers the phone is the company that does the work, and David, the owner and lead technician, oversees how jobs are done.
The phone is answered 24 hours a day, 7 days a week, all year. If your door will not secure at two in the morning, you do not have to wait until business hours to find out what to do. Our emergency locksmith service covers those situations, and a lot of emergency calls end in a lock replacement once the immediate problem is handled.
We also try to stay inside our lane. If your actual problem is a lost key, a car issue, or a safe that will not open, we will say so and route you to the right service, not stretch a lock replacement to cover it.
Lock replacement around Montebello: homes, climate, and neighborhoods
Montebello is a city with a clear mix of housing, and that mix shapes what we usually find behind a worn lock. In the older southern and central blocks, you see 1920s Spanish-style bungalows. In South Montebello, replacing worn mid-century locksets in these bungalows is a regular job. Many of those homes have had their doors rehung, repainted, and re-hardwared over the decades, so the door prep is not always what a new lock expects. We check the bore, the edge, and the strike before choosing hardware so the new lock sits properly.
Toward the hills, North Montebello and the Montebello Hills area are dominated by larger postwar ranch tracts, and many of those homes still carry their original mid-century locksets. Those locks are now decades old. Springs weaken, cylinders wear, and finishes flake. A tract home with original hardware on every door is a good candidate for replacing the front and back sets together, so everything matches and every door is held to the same standard. Hillside streets near the Montebello Hills sit on sloped lots with longer driveways, which is worth remembering when you think about which doors are visible from the street and which are not.
Along Garfield Avenue and Beverly Boulevard, condo and apartment buildings make apartment lock replacement a common request. Along the Whittier Boulevard corridor, the commercial strip brings storefront and business lock replacement, and the area near The Shops at Montebello has retail doors that take heavy daily use.
In ZIP code 90640, the practical seasonal issue is heat. Summers run hotter than coastal Los Angeles, and winters are mild. Older wood doors expand in the heat, which can make a latch bind or a deadbolt drag against the strike. We see people blame the lock when the real cause is a swollen door. Sometimes the right answer is a new lock, and sometimes it is adjusting the door and strike first. If the lock is already worn, the heat just makes the problem obvious.
Marine-layer mornings, mostly in late spring, do not change much for hardware. The heat-driven door movement is the seasonal effect to watch.

Call (213) 577-1366What to ask any locksmith, including us
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. It is reasonable to ask any locksmith for that license number before they touch your door. A legitimate company will give it to you without fuss, and you can verify it with the state.
Beyond that, ask whether the company is local, whether the person arriving works for the company that answered the phone, and whether you will be told the full job details before work begins. Be cautious if a quote seems to change once someone is standing at your door, or if a technician pushes to drill out a lock that could have been handled more gently.
For changing every lock in a home after a move or a lost key, see our page on changing locks. It covers a slightly different situation from replacing a single failed lock, and we are happy to help you pick the path that fits.
Frequently asked questions
How do I know if I need lock replacement or a repair?
If the lock is sticking, loose, or worn from years of use, replacement is often the better route, especially on older hardware. If the problem is a bent latch, a misaligned strike, or a single failed part, a repair may be enough. We look at the lock and tell you honestly which makes sense.
Can you replace a broken lock at night or on a weekend?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. If your door will not secure, call and we will work out the quickest safe way to protect the opening and replace the broken lock.
Do I have to replace the whole lock if I only lost a key?
Not always. If the lock itself is in good shape, rekeying it so old keys no longer work is often the more economical route. If the lock is already worn or damaged, replacing it makes more sense. We help you decide based on its condition.
Can you match my existing finish and style?
Often we can. Finish and style options depend on the lock and the manufacturer, and some older styles are no longer made. We will go over what is available that fits your door and your look before we install anything.
Will a new lock fit my older door?
Usually yes, but older doors, especially in some of Montebello's 1920s bungalows, may have unusual bores or worn edges. We check the door before choosing hardware and correct the prep when needed so the new lock works properly.
Can you replace locks on several doors so they all use one key?
Yes. Keying multiple locks alike is common, especially after a move or on a tract home with original hardware on every door. We can set up the front, back, and side doors to work with one key.
Do you handle lock replacement for businesses as well as homes?
Yes. We handle business lock replacement for storefronts and offices, including heavy-use doors that need sturdier hardware. Complex projects like access control are scoped separately, but a straightforward commercial lock swap is routine for us.
Are you licensed to do locksmith work in California?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before work begins. Call (213) 577-1366 and ask us about our license information directly.
Is a smart lock a good replacement option for my front door?
It can be, depending on your door, your habits, and how comfortable you are with batteries and apps. A solid mechanical lock is still a perfectly good choice for many homes. We can explain the tradeoffs and install whichever suits you.
