What does lock replacement actually mean?
Lock replacement is exactly what it sounds like: the old lock comes off the door and a new one goes on. That can be a knob, a lever handle, a deadbolt, a mortise lock in an older door, or a combination of them. The keys change too, because a new lock arrives with its own key pattern, and your old keys stop working in it.
People usually call us for one of a few reasons. A key snapped and the cylinder is chewed up. A deadbolt that used to throw smoothly now fights you every morning. A latch has gone slack and the door no longer holds shut. A tenant moved out, or a relationship ended, and nobody can say how many copies of the key are floating around. Or the hardware is simply old, and you want a security lock upgrade before something goes wrong rather than after.
Whether you need to replace a damaged lock on a front door, replace a broken lock at the back of a shop, or swap out every lock in a rental, the work is the same at its core. We find out what the door and frame can accept, pick hardware that fits, install it square, and make sure it locks and unlocks cleanly before we leave.
Should you replace the lock, rekey it, or repair it?
Replacement is not always the right answer, and we would rather tell you that than sell you hardware you do not need. The honest question is what is actually wrong with the lock. Sometimes the lock is fine and only the keys are the problem. Sometimes one worn part is the whole issue.
Here is how we sort it out on most calls:
- Choose replacement when the lock is physically damaged, badly worn, corroded, forced open, missing parts, or too old to trust. It is also the right call when you want a different style, a stronger grade, or a keypad or smart option.
- Choose rekeying when the lock body is in good shape and you only want old keys to stop working. Rekeying changes the internal pins so a new key fits. It is often the more economical route, and you can read more on our lock rekey service page.
- Choose repair when one component is the issue, such as a loose handle, a sticking latch, or a bolt that is slightly out of alignment. Our lock repair service page covers that.
- Choose replacement over repair when the repair would cost nearly as much in time and parts as a new lock, or when the lock is so worn that it will fail again soon.

Call (213) 577-1366How does lock replacement work, step by step?
Whether it is a house in the morning or a shop at two in the night, the process follows the same order. Nothing here is rushed, and you will know what is happening before it happens.
- You call (213) 577-1366. We are answered around the clock, every day of the year. Tell us what the lock is doing, what kind of door it is, and whether the door is currently secure.
- We ask a few practical questions: how many locks are involved, whether they need to be keyed alike, whether the door is wood, metal, or glass, and whether there is any damage to the frame.
- A mobile van comes to your address in Pomona. On arrival we look at the door and frame before touching the lock, because the right new hardware depends on the bore holes, the backset, the door thickness, and the strike plate.
- We explain what we recommend and why, including whether a rekey or repair would do the job instead. You decide before work starts.
- We remove the old hardware, check the door edge and strike for splintering or misalignment, and correct what can be corrected on site.
- We fit the new lock, set the strike so the bolt throws fully into the frame, and test it from both sides with the door open and closed.
- We hand over the keys, show you how any special features work, and point out anything about the door itself that deserves attention later.
Front door, house, and apartment lock replacement
A front door lock does more daily work than any other lock you own. It gets used by everyone in the household, in a hurry, with groceries in one hand. That is why front door lock replacement is usually where wear shows up first. Keys get sloppy, handles loosen, and a deadbolt starts to drag.
For a house lock replacement, we often suggest looking at the whole door rather than only the knob. A new handle set paired with a worn-out deadbolt leaves you with one strong point and one weak one. If the deadbolt is the weak link, our deadbolt installation page explains what we look at. If you want something sturdier than standard hardware, the high-security locks page covers pick-resistant and restricted-key options. And if you are weighing a keypad or app-based lock, the smart lock installation page explains what that involves.
Apartment lock replacement has its own rhythm. Tenants change, keys multiply, and a unit can pass through several hands in a few years. Residents generally need the landlord's permission before changing a lock, so we work with whoever has the authority to approve the change. Property owners who manage several units can read about how we handle that on our locksmith for landlords page.

Call (213) 577-1366Commercial and business lock replacement
Commercial lock replacement is a different job from a house. Business doors take heavier traffic, often have glass or aluminum frames, and may need locks that meet different expectations for exits and hours of use. A storefront lock might be opened and closed dozens of times a day, and the wear shows.
When a business owner calls about a business security upgrade, we usually start with a few questions. Who has keys today and do you know where all of them are? Has anyone left the company? Was there a break-in or an attempted one? Does the door need to be easy to exit in an emergency? Those answers shape whether we recommend a straightforward replacement, a keyed-alike set across several doors, or a restricted key system that blocks unauthorized copying.
If your needs go beyond swapping a single cylinder, such as multiple doors, door hardware, or controlled access, our commercial locksmith page lays out the wider picture. This page stays focused on the replacement itself: getting a failing or compromised lock out and a sound one in.
What affects the cost of lock replacement in Pomona?
We do not quote numbers on a web page, because honest pricing depends on the door in front of us. What we can do is tell you exactly what moves the cost up or down, so nothing surprises you when we explain the options on site.
- The type of lock: a basic knob costs less to supply than a grade-one deadbolt, a mortise lock, a high-security cylinder, or an electronic lock.
- The number of locks: replacing one lock is a different job from replacing every exterior door in a building, and whether they are keyed alike affects the work.
- The condition of the door and frame: if the bore is off, the edge is split, or the strike area is damaged, that has to be addressed for the new lock to work properly.
- Older or unusual hardware: period doors and mortise sets may need more careful fitting, and some parts take longer to source.
- Time of day: after-hours and emergency calls are handled differently from scheduled daytime work.
- Whether replacement is needed at all: if rekeying or a small repair solves the problem, that is usually the more economical route, and we will say so.
Why call Wilshire Lock & Key for lock replacement?
We have been in business since 1987. That is a long time to have fitted, fixed, and replaced locks on every kind of door, and it shows in how we approach an unfamiliar one: look first, talk second, then work.
We are a real company with a storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans that come to you. When you call (213) 577-1366, you reach us, not a call center that sells your job to whoever is free. There are no dispatch middlemen between you and the person who shows up. David, the owner and lead technician, oversees the work.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith you are considering for their license number, and check it yourself. It is a reasonable request, and a company that dodges it is telling you something.
If your situation is urgent, such as a door that will not secure after a break-in, our emergency locksmith page explains how after-hours calls work. The phone line is open 24/7 either way.

Call (213) 577-1366Lock replacement around Pomona: older homes, heat, and busy corridors
Pomona is a mix of eras, and the lock work changes with them. Pomona has a large stock of Victorian, craftsman, and period revival homes, concentrated in the Lincoln Park, Wilton Heights, and Hacienda Park historic districts. Doors in those houses can be old solid wood with unusual bores or mortise-style hardware. Replacing a lock there is often more about fitting new security to a door that should be preserved than about swapping in the first thing off a shelf. We look at what the door can handle and choose hardware that works with it rather than cutting it up.
Postwar tracts fill much of the rest of the city, and the 1980s Phillips Ranch planned community sits in the southwestern hills. Hardware on homes from those periods may be original or have been replaced more than once, so it is common for a house to have a mix of lock brands, none keyed alike. Replacing the exterior locks and bringing them onto one key is a popular, practical upgrade for those homeowners.
Apartment buildings line the Holt and Garey corridors, and the Garey Avenue corridor and other dense commercial streets often have security screen doors and storefront gates. A screen door with its own latch adds a second lock to think about, and we check that the new main lock and the screen door hardware work together without getting in each other's way.
Pomona's inland valley climate brings hot, dry summers and periodic Santa Ana winds, and wood doors and frames expand and stick during prolonged heat. This matters for replacement jobs. A door that is rubbing in the frame can make a good lock feel broken, and replacing the lock will not cure that. Before we sell you new hardware, we check whether the door is binding and whether the strike simply needs adjusting. Sometimes the right answer is a small fix, not a new lock.
Here is a situation we see across the city: a small business in the downtown Arts Colony has a break-in, and the owner needs the damaged lock replaced so the door can be secured the same day. In that case, replacing the lock is the first step, and we also look at the frame and strike for forced damage so the new lock is not fitted into a door that cannot hold it. If you are near Pomona's downtown or anywhere across ZIP codes 91766, 91767, and 91768, the process is the same: call, describe the door, and we come to you.
Our storefront is in Westwood, about 43 miles from Pomona, and the mobile vans are how we serve the city. For related needs nearby, our Pomona locksmith hub lists the full range of services we offer here.
Frequently asked questions
How do I know if I need a new lock or just a rekey?
If the lock works smoothly and looks sound but you worry about who has keys, a rekey is usually enough. If the lock is damaged, worn, forced, or failing, replacement is the better choice. We check the lock on site and tell you which one applies.
Can you replace a lock on an older Pomona home without damaging the door?
Yes, that is the goal. Older Victorian and craftsman doors may have unusual bores or mortise hardware, so we look at what the door can accept first. We choose hardware that fits the existing preparation instead of cutting more wood than necessary.
Will the new lock work with my old keys?
Usually not. A new lock comes with its own key pattern, and your old keys stop working in it. If you want several doors on one key, tell us up front and we can set the new locks keyed alike.
Can you replace the locks on my rental or apartment?
We can, but the change needs approval from whoever holds the authority over the unit, typically the landlord or property manager. Tenants should check their lease before changing locks. We can work with the owner or manager to handle the replacement.
My door sticks during hot weather. Will a new lock fix it?
Not always. In Pomona's hot, dry summers and Santa Ana wind periods, wood doors and frames can swell and bind. If the door rubs, a new lock will not cure it. We check alignment and the strike first and tell you honestly whether replacement is worthwhile.
Do you replace business and storefront locks in Pomona?
Yes. We handle business lock replacement, including after break-ins and for businesses that want a security upgrade after staff changes. For storefront-specific problems like gates and roll-up doors, see our storefront lock repair page.
What should I check before hiring a locksmith to replace my lock?
Ask for their California BSIS LCO license number and check it. Ask who will actually come to your door, and whether the company explains options before starting. A trustworthy locksmith will answer plainly and let you decide.
Can I get a lock replaced at night or on a weekend in Pomona?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. After-hours work is handled differently from scheduled work, and we will explain how when you call.
