When does a lock need replacing instead of fixing?
Most locks don't fail all at once. The key gets stiff, then it needs a jiggle, then the latch hangs up every third time you close the door. One day the key snaps, the cylinder spins freely, or the handle comes off in your hand. Lock replacement is the right call when the hardware itself has reached the end of its life, or when it was never strong enough for the door it's supposed to protect.
If you're trying to decide whether yours has crossed that line, these are the signs we see most often when someone calls about a door lock replacement:
- The key turns but the bolt doesn't move, or the cylinder spins without catching anything.
- The handle or lever sags, wobbles, or no longer springs back on its own.
- There is visible damage after a break-in attempt: a bent latch, a cracked housing, pry marks around the strike.
- The key way is worn smooth, or your keys are copies of copies and only work with effort.
- The lock is original builder-grade hardware from decades ago and parts are no longer easy to find.
- You've lost track of how many keys exist, and you'd rather start fresh than guess.
Should you replace, rekey, or repair the lock?
This is the question we try to answer honestly before anyone picks up a drill. A lock that works smoothly but whose keys are out there somewhere doesn't need to be thrown away. It needs to be rekeyed, which changes the internal pins so old keys stop working. That is usually the more economical route, and we cover it on our lock rekeying page.
If a lock is mostly sound and just one part has worn, such as a spring, a latch, or a loose mounting, a repair may be enough. Our lock repair service is built for that situation. We would rather fix a good lock than sell you a new one you didn't need.
Replacement makes sense when the damage is structural, when the lock is badly corroded or worn through, when the hardware is a style nobody supports anymore, or when you want a different level of security than the old lock can offer. A replaced lock also gives you a clean slate: new keys, new internals, and no history of who may have copied what.
When you call, tell us what the lock is doing and what the door is like. Often we can sort out the likely answer over the phone, and we confirm it in person once we can see and handle the hardware.

Call (213) 577-1366How does a lock replacement visit work, step by step?
Whether we're at your front door in the evening or at a storefront first thing in the morning, the process follows the same honest order. Nothing gets installed until you understand what you're getting.
- You call (213) 577-1366 and a person answers, any hour. You describe the problem, the type of door, and whether the building is a house, apartment, or business.
- We go over what we can tell from the description and what we'll need to see in person, so you know what to expect before anyone drives out.
- A technician arrives in one of our mobile service vans and inspects the lock, the door, the strike plate, and the frame. A failing lock is sometimes a symptom of a door that has shifted or a frame that has warped.
- We explain the options plainly: repair, rekey, or replace, and if replacing, which hardware fits your door and how you use it. You decide.
- We remove the old hardware and check the door preparation. Bore holes, latch edge, and strike all need to be right, or even a premium lock won't work properly.
- We install the new lock, set the strike so the bolt throws fully into solid framing, and test it repeatedly with the door open and closed.
- We cut or hand over the keys, make sure every one works, and walk through how the lock operates so nothing about it is a surprise later.
What affects the cost of lock replacement in Agoura Hills?
We don't quote numbers in a web page, because the honest answer depends on your door. What we can do is tell you exactly what moves the cost up or down, so nothing at the door feels like a surprise.
- The type of hardware: a basic knob set, a deadbolt, a multipoint lock, a keypad lock, and a commercial-grade cylinder all sit in very different places.
- The security level you want. Higher-security cylinders with restricted keys cost more than standard hardware, and they take longer to get duplicate keys for.
- How many locks are being replaced, and whether you want them all keyed alike so a single key opens every door.
- The condition of the door and frame. If the bore is damaged or the strike area is split, repairing that is part of doing the job correctly.
- Door material and thickness. Solid wood, metal, and glass-panel doors each need different handling.
- Whether the work is a scheduled visit or an urgent one at an odd hour, and how far the technician travels to reach you.
- Whether it's a residential or commercial job, since commercial hardware is built differently and often has to meet other requirements such as exit rules.

Call (213) 577-1366What's different about front door, house, and apartment lock replacement?
Front door lock replacement is the job most people call about, and it's a good place to spend a little thought. The front door gets the most use and the most scrutiny from anyone looking for an easy way in. A good front door setup is usually a quality deadbolt plus a handle set, with a strike plate fastened into the framing with long screws rather than only the thin trim. If you want to add or upgrade the bolt, our deadbolt installation page explains what that involves.
House lock replacement often covers more than the front. Back doors, side gates, garage entry doors, and sliding doors may all have older hardware. Replacing them together lets us match the keys so you carry one instead of five. We'll also point out which doors are fine as they are, because not every lock in the house needs attention.
Residential lock replacement and apartment lock replacement are similar in method but different in permission. If you rent, check your lease before changing hardware, and talk to your landlord or property manager first. If you manage rental property, we can help set up a consistent approach between tenants so that turnover doesn't leave old keys in circulation. Keep in mind that a replaced apartment lock should still allow whatever access the building legitimately needs.
If you replaced a lock because you were locked out in the first place, the lockout and the replacement are separate problems, and we handle them in that order: get you inside first, then decide what the lock actually needs.
What about commercial and business lock replacement?
Commercial lock replacement isn't just a bigger version of residential work. Storefront doors, back-office doors, and steel service doors use different hardware: heavier cylinders, mortise locks, exit devices, and closers that all have to work together. A lock that is replaced without considering the closer or the exit hardware can leave a door that doesn't latch or that can't be opened quickly from the inside.
When a business owner asks about a business security upgrade, we start with the questions that matter. Who has keys right now? Has anyone left the company with one? Are the doors stout enough that a better lock actually improves anything? We would rather tell you honestly that the door or frame is the weak point than sell you a lock the door can't support.
For hardware beyond the cylinder itself, see our pages on commercial door hardware and, for the lock-and-latch side of a front entrance, storefront repair. Where a business needs a change of keys because of a staffing change, replacing the cylinders is often a clear and efficient fix, and we can set the new keys up so that everyone gets access to only what they should.

Call (213) 577-1366Is a lock replacement a good moment for a security upgrade?
Yes. Since the old lock is coming out anyway, you're only deciding what goes in. A security lock upgrade does not have to mean something complicated. It can be as simple as moving from a basic builder-grade deadbolt to a sturdier one, or fitting a better strike plate and longer screws.
If you want keyless entry, codes you can change or share, or a lock you can check from your phone, that's covered by our smart lock installation work. Smart locks suit some households very well and others not at all, so we'll talk through how you actually use the door before recommending one. If your concern is pick resistance or key control, high-security locks use restricted keyways so that keys can't be casually copied at a hardware counter.
Whatever you choose, we'd rather match the lock to the door and the household than push the most elaborate option.
Why call Wilshire Lock & Key for lock replacement?
We've been in business since 1987, and we run from a real storefront at 10740 Wilshire Blvd in Westwood with mobile service vans for jobs like yours. When you call (213) 577-1366, you reach us, not a national call center that sells your job to whoever is free. One company handles the call, the visit, and the follow-up, with no dispatch middlemen between you and the person doing the work.
David, the owner and lead technician, oversees the work we do. That matters on replacements, where small details such as strike alignment, bore condition, and key cutting decide whether a lock feels solid for years or becomes a problem again.
One thing worth knowing about any locksmith, including us: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for that license number before work begins. A reputable company will tell you without hesitation.
We answer 24 hours a day, seven days a week, year-round, so a broken lock at night or on a holiday still gets a person on the phone. Agoura Hills sits about 28 miles from our base, and we serve 140 cities across Los Angeles and Ventura counties, so it's a regular part of our service area.
What does lock replacement look like around Agoura Hills?
Agoura Hills has a distinct mix of housing, and that shapes what we see on replacement jobs. Most homes are 1960s to 1980s ranch and two-story tract houses built as the Ventura Freeway corridor developed, with townhomes and condos near Kanan Road and Thousand Oaks Boulevard. Hardware from that period has often been replaced once or twice already, and the original doors and frames may be showing their age. In the 91301 ZIP code, a replacement call is frequently about more than the lock: the strike, the bore, and how the door fits its frame.
In neighborhoods like Morrison Ranch and Lake Lindero, we'd expect many replacement calls to come from homeowners who want to refresh the front door hardware after years of use, or who want new keys after a move. Both neighborhoods operate under HOAs, so if you're changing visible exterior hardware such as handle sets, it's worth checking your association's rules on finish and style before you buy. Fountainwood, Forest Cove, Hillrise, and Annandale have their own mix of homes, and the same advice about checking first applies wherever there's an association.
Old Agoura is different. Larger equestrian lots and older rural homes mean more gates, outbuildings, and barns, and the hardware there takes more weather and more dust than a typical suburban front door. Horse-property gate and barn lock work is a real part of the area, and when a gate latch or barn lock is worn out, replacing it with weather-appropriate hardware is often the answer. For gates specifically, our gate lock repair page covers that side in more detail.
The climate matters too. Agoura Hills is an inland valley with hot, dry summers and strong Santa Ana winds through the canyons. Day-to-night temperature swings can make wood doors and frames move with the seasons, so a lock that sticks in one month and works fine in another may really be a door-fit problem rather than a faulty lock. We check for that before we replace anything, because a new lock on a door that binds will just wear out sooner.
The city also sits in a wildland-urban interface, and some housing was rebuilt after the 2018 Woolsey Fire. Newer rebuilt homes often have newer doors, which usually accept modern hardware without trouble. Older homes may need a bit of adjustment to the bore or the strike. For businesses along the Thousand Oaks Boulevard and Kanan Road corridors, storefront and office lock replacement is a routine part of the work, and for townhome residents near Whizin Market Square, we treat the replacement with the same care as any house door, with extra attention to shared-property rules.
Frequently asked questions
How long does it take to replace a door lock?
A straightforward lock on a door in good condition is usually a short job. It takes longer if the door needs repair, if several locks are being replaced, or if the hardware is more complex. We'll tell you what to expect once we know what we're dealing with.
Can you replace a lock on the same day I call?
We answer the phone around the clock at (213) 577-1366, and for urgent situations such as a broken lock or a door that won't secure, we work to get to you as soon as we can. Agoura Hills is some distance from our Westwood base, so we'll give you a straight answer on timing when you call.
Do I need a new lock, or can you just rekey it?
If the lock works well and you only want old keys to stop working, rekeying is usually the more economical route. If the lock is damaged, worn out, corroded, or not strong enough for the door, replacement is the better answer. We'll tell you which applies after looking at it.
Will the new lock fit my existing door?
Most residential doors take standard hardware, but we check the bore holes, the latch edge, and the door thickness before choosing. Older doors or doors that have shifted may need small adjustments so the new lock works smoothly.
Can you replace several locks and make them all work with one key?
Yes. We can key multiple locks alike so that one key opens the front door, back door, and any other doors you choose. This is common when replacing hardware throughout a house or a small business.
I rent my apartment. Can I replace the lock myself?
Check your lease and talk to your landlord or property manager first. Many rentals require permission, and the building may need to keep access. If you're a landlord changing locks between tenants, we can help with that.
What affects the cost of a lock replacement?
The hardware type, the security level, how many locks are involved, the condition of the door and frame, and whether the visit is scheduled or urgent all play a part. We explain the options before any work starts so you can decide with a clear picture.
Should I ask a locksmith for a license?
Yes. California requires locksmith companies to hold a BSIS LCO license, and you can ask any locksmith for it before they begin work. A legitimate company will be glad to share it.
Do you handle lock replacement for businesses in Agoura Hills?
Yes. We replace locks on storefronts, offices, and service doors, and we look at the whole door setup, including closers and exit hardware, so the new lock works properly with everything else. Call (213) 577-1366 and tell us about the door.
