When should you replace a lock instead of repairing it?
A lock has one simple job, and when it stops doing it cleanly you usually feel it before you see it. The key drags going in. The deadbolt needs a shoulder shove to throw. The knob spins loose on the door, or the latch only catches the strike plate if you pull the door hard. Those are the early warnings. The later ones are blunter: a key snapped off, a cylinder that won't turn at all, or a door that someone pried at and now has a bent lock body.
Replacement makes sense when the hardware itself is the problem, not just how it's set up. If one small part has failed on an otherwise sound lock, a lock repair is often the more economical route, and we will say so on the phone instead of selling you a new lock you don't need. Here is when we lean toward replacing:
- Internal wear: pins, springs, and wheels have worn down until the key works only some of the time, or only if you jiggle it.
- Physical damage: a forced-entry attempt, a hard impact, a slammed door that bent the latch, or a body that has cracked.
- Corrosion or fouling: dust, grit, and weather have gotten into the cylinder badly enough that cleaning won't bring it back.
- Outdated or builder-grade hardware: a thin knob set with no real deadbolt, or a lock that has been on the door for decades.
- Loose, sagging, or mismatched hardware: handles that rotate on the door, finishes that are failing, or a mix of different locks with a mix of different keys.
- Lost trust: you don't know who has copies of the keys and the lock itself is already tired, so starting fresh is the cleaner answer.
How does lock replacement work, step by step?
Here is how a typical replacement goes, whether it is a front door at a house or a back door at a shop. The details change with the door, but the order does not.
- You call (213) 577-1366. A person answers at any hour. Tell us what kind of door it is, what the lock is doing, and whether the door is secure right now.
- We talk through whether replacement is really the right move. If a repair or a rekey would solve it, we say that before anyone drives out.
- A technician comes in a mobile van carrying common cylinders, deadbolts, knob and lever sets, and commercial hardware. Irwindale is roughly 32 miles from our Westwood storefront, so we give you an honest arrival window when you call and update you if anything changes.
- We inspect the door before touching the lock: thickness, bore holes, backset, latch, strike plate, and the frame. A new lock is only as strong as the door and frame around it, and we point out weak spots we see.
- We explain the hardware options and the cost before work begins, so there are no surprises on the invoice.
- We remove the old lock, fit the new one, align the strike, and test it with the door open and closed. Every key gets tried, and the latch and bolt get checked for smooth action.
- We hand over the keys, show you how the hardware works, and give you the old lock if you want it. If the door or frame needs reinforcing, we tell you plainly and let you decide.

Call (213) 577-1366What affects the cost of lock replacement in Irwindale?
We don't post 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, ours included.
- The type of lock: a basic keyed knob, a deadbolt, a lever set, a mortise lock, and a commercial-grade cylinder are different products at very different weights.
- The hardware grade: residential locks are rated in grades, and a sturdier grade costs more and holds up longer on a busy door.
- How many locks: replacing one lock is a different job from replacing every exterior door on a house or a row of doors at a business.
- Keying: having several locks work with one key, or ordering restricted keys that can't be copied at a hardware store, adds to the job.
- Door and frame condition: if the bore is damaged or the frame is split, repairing that is part of making the new lock actually secure.
- Specialty requirements at a business: fire-rated doors, accessible lever handles, panic hardware, and master-key layouts all change what we install.
- Time of day and distance: after-hours calls and the drive out to Irwindale are part of the picture, and we explain them up front.
How do we keep your cost reasonable?
If you want to keep spending down, the usual lighter-cost option is to replace only what has failed. Sometimes that means swapping a cylinder and keeping a good lock body, or fitting a solid deadbolt and leaving a knob set that still works. We won't talk you into replacing everything when one part is the weak link, and we won't talk you into a cheap lock for a door that takes a beating every day. You get the options, the trade-offs, and the cost before we start.
Front door, house, and apartment lock replacement
Most residential replacement calls start the same way: the front door lock has gone bad, or someone wants a better one. A house lock lives a hard life. It gets slammed, leaned on with grocery bags, baked by afternoon sun, and used by a dozen hands. After years of that, even a decent lock wears out. A front door lock replacement is also a chance to fix what was wrong from the start, like short screws in the strike plate, a cheap latch with no deadbolt behind it, or a handle set that never lined up with the door.
We typically pair a quality deadbolt with a matching handle set, and we can key them so one key runs both. If a door needs a stronger deadbolt or a first-time one, our deadbolt installation page covers that in more detail. If your real concern is who holds keys after a move or a breakup, the change locks page explains the options for that situation.
Apartment lock replacement has one extra wrinkle: permission. If you rent, check your lease and let your landlord or manager know before changing hardware, since many leases require it. If you manage the property, we can replace locks unit by unit and keep the keying organized so you are not left with a pile of mismatched keys. In either case, tell us whether the lock is on a unit door, a utility door, or a shared entry, because the right hardware differs.

Call (213) 577-1366Commercial lock replacement and business security upgrades
In Irwindale, commercial work is not a side line. The city is mostly gravel quarries, warehouses, and manufacturing plants, with a very small residential population, so a good share of the doors that need attention here are business doors. Business lock replacement is a different animal from replacing a house lock. The door gets used all day, the hardware has to meet code, and the keys often belong to a lot of people.
A business security upgrade usually starts with one of a few triggers: an employee left and nobody knows where their key went, a door has been forced, the original hardware is simply worn out, or an inspection flagged something. We look at what you actually need and avoid piling on hardware you don't. Common jobs include:
- Replacing worn or damaged cylinders and lock bodies on office, shop, and warehouse doors.
- Moving to restricted keyways so keys can't be copied freely.
- Matching new locks to an existing key system, or planning a master key system when keying has gotten out of hand.
- Swapping tired exit devices and trim, which overlaps with our panic bar installation work.
- Choosing the right commercial door hardware for heavier, busier doors than a house lock can handle.
What does lock replacement look like around Irwindale?
Irwindale has a split personality, and the work follows it. The small residential enclave near the Civic Center, around Arrow Highway and Irwindale Avenue, is a handful of modest single-family homes, mostly early-to-mid 20th century. Homes of that age are the kind where we expect to find decades-old knob sets, doors that have been repainted and have shifted a little, and locks that were never upgraded. When someone in that enclave asks for a lock change, the job is often a full replacement of a tired front door lock, and we check the door fit as part of it. Homes in either ZIP code here, 91706 or 91702, get the same treatment.
Along the Arrow Highway and Irwindale Avenue corridors, and especially the Live Oak Avenue industrial district, the work leans commercial. Warehouse and plant doors take constant traffic, and master-key and panic-hardware work is a regular need along those corridors. Replacing a worn exit device or a shared-key cylinder there is less about convenience than about keeping a working building secure and legal to exit.
Climate matters too. Summers are hot, and quarry operations add dust that can work into exterior padlocks and gate hardware. A padlock that has been gritted up for a few seasons often stops turning smoothly, and no amount of oil fixes grit that has packed into the mechanism. Near the quarry and equipment-yard perimeters, and out toward the Santa Fe Dam area, we see chains, padlocks, and gate hardware that take a beating. Replacing a gritty padlock with a better-sealed one is usually the right call, and our gate lock repair page covers when a gate lock can be saved instead. Santa Ana winds that rake the open San Gabriel River corridor also slam doors and loosen hardware, which is one more reason to check latches and strikes while we are on site.

Call (213) 577-1366Why call Wilshire Lock & Key for lock replacement?
We have been in business since 1987, and that is a long time to learn what makes locks fail and which replacements hold up. We operate from a real storefront at 10740 Wilshire Blvd in Westwood, Los Angeles, with mobile service vans that come out to you. That matters: if a part has to be matched or ordered, there is a shop behind the van, not a call center.
We are one company. When you call (213) 577-1366, you are not reaching a dispatch middleman who hands the job to whoever is closest. The people who answer work for us, and the technician who arrives works for us. David, the owner and lead technician, oversees the work, and he cares about the details, like whether a strike plate is anchored into the stud or just the trim.
We serve 140 cities across Los Angeles and Ventura counties, so Irwindale is part of our regular territory, even at 32 miles from our base. Our phone is answered around the clock, every day of the year, because locks fail at night and on holidays as often as they do on weekday mornings.
Replace, rekey, or repair: which fits your lock?
These three get mixed up all the time, so it helps to separate them. Replacement means new hardware on the door. A repair fixes a specific failed part and keeps the lock. A rekey changes the internal pins so old keys stop working, while the lock itself stays. If your lock is in good shape but you've lost keys or want to cut off past key holders, a lock rekey may be all you need, and it is often the more economical route. If the lock is worn, damaged, or outdated, rekeying a failing lock just spends money on hardware that is on its way out.
A quick way to decide: if the lock works smoothly and your only concern is who has keys, think rekey. If one part has broken, think repair. If the lock is damaged, worn, or weak, replace it. When you call, describe what you see and we will steer you to the option that fits.
How do you check that a locksmith is legitimate?
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 you are considering for that license number, and verify it with BSIS before they start work. Also look for a business with a real address, a technician who identifies the company when they arrive, and a clear explanation of cost before anything is drilled or removed. Be cautious of anyone who won't explain the work, won't give a real company name, or pushes you toward replacing everything on the spot.
Frequently asked questions
Can you replace a lock on the same day I call in Irwindale?
We answer the phone 24 hours a day, seven days a week, and we send a technician out as soon as we can. Irwindale is about 32 miles from our Westwood storefront, so arrival depends on where vans are and traffic. We give you an honest window when you call (213) 577-1366 rather than promising something we can't control.
How do I know if I need a new lock or just a rekey?
If the lock works smoothly and your concern is who has keys, rekeying is usually the lighter-cost option. If the lock is worn, damaged, corroded, or low-grade, replacement is the better use of money. Tell us what the lock is doing and we'll say which one fits.
Will a new lock fit my older door?
Usually yes, but we check before we start. We look at door thickness, bore holes, backset, latch, and the frame. Older doors, like those in Irwindale's early-to-mid 20th century homes near the Civic Center, sometimes need a little extra fitting, and we tell you up front if they do.
How much does lock replacement cost?
It depends on the lock type and grade, how many locks you're replacing, the keying you want, the condition of the door and frame, and the time of day and distance. We explain the options and the cost before work begins. We don't quote numbers on a web page because every door is different.
Do you replace locks on businesses and warehouses in Irwindale?
Yes. Much of Irwindale is warehouses, plants, and industrial yards, and we replace cylinders, lock bodies, exit hardware, and gate or padlock hardware for businesses. We can also match new locks to an existing key system or plan a new one.
I rent my apartment. Can I replace the lock myself or ask you to?
Check your lease first. Many leases require landlord approval or require you to provide a copy of any new key. If you get approval, we can do the work. Property managers can also have us handle a group of units so the keying stays organized.
My door was damaged in a break-in attempt. Can you fix it?
Call us right away at (213) 577-1366. We assess whether the lock, the latch, the strike, or the frame took the damage, then replace what is needed so the door actually secures again. We'll tell you if the frame needs reinforcing too.
Do I get the old lock back and new keys?
You get new keys with the new lock, and the old hardware is yours if you want it. Ask for it when the technician is on site. If you want extra copies made, we can do that while we're there.
How can I verify that a locksmith is licensed?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for their license number and check it with the Bureau of Security and Investigative Services before work begins. A legitimate company will not hesitate to answer.
