What does car key replacement actually involve?
Car key replacement means getting a working key for your vehicle when you don't have one, or don't have enough of them. That covers three different situations: a spare when you're down to a single key, a replacement when your keys are lost or stolen, and a duplicate when a key still works and you simply want another. People use the terms loosely, but they matter, because what we have to do is different in each case.
The work has two halves. The first is car key cutting: shaping the metal blade, if your key has one, so it turns the door and ignition. The second is programming: teaching the car's electronics to accept the new key. Some keys need only cutting. Some need both. Some modern keys are mostly electronics with little or no traditional blade, and for those the programming is the real job.
We do both at your vehicle. Our mobile vans carry the cutting and programming equipment, so for most jobs the car stays where it is and nobody pays for a tow just to get a key made. When a job is better handled at our Westwood storefront at 10740 Wilshire Blvd, we tell you that up front rather than letting you find out later.
One thing we won't do is guess. Whether your car uses a plain cut key, a key with a built-in chip, a remote-head key, a flip key or a push-button smart key depends on the make, model and year, and a description over the phone isn't always enough. We confirm by VIN and by looking at the vehicle in person. If a particular car can only be keyed through the dealer, we'll say so plainly. We'd rather lose the job than waste your evening on something we can't finish. For the wider picture of what we do on vehicles, see our automotive locksmith service page.
Which car key situation are you in?
Most calls fall into one of a few situations, and naming yours helps us tell you quickly what to expect. None of these is unusual, and none of them is something to feel foolish about.
If you're not sure which one fits, just describe what happened when you call. We'll sort it out together.
- You have one key and want a spare. This is the easiest position to be in. A working key gives us something to work from, and a spare made now is almost always less trouble than one made after the last key vanishes.
- You've lost every key. We can still make a new one, but the process leans harder on proving the car is yours and identifying it exactly by VIN. Our page on lost car key replacement walks through that in more detail.
- Your key works, but the remote or fob doesn't. Sometimes the key is fine and the fob electronics are the problem, which is a different repair from cutting a new blade. See key fob replacement for how we handle those.
- The key is worn, bent or cracked. A key that sticks, needs jiggling, or has started to bend is telling you it won't last. Replacing it before it snaps in the ignition is far easier than dealing with the aftermath.
- The key was stolen along with a bag or wallet. In that case you may want to think about whether the old key should keep working. We'll talk through that with you, since programming a new key can sometimes be paired with removing lost ones, depending on the vehicle.

Call (213) 577-1366How does mobile car key replacement work, step by step?
Here is the sequence we follow on a typical job. The details shift from car to car, but the order stays about the same. Because it's one company answering the phone and sending the van, the person you describe the problem to is part of the same operation that does the work. There's no dispatch middleman relaying a half-understood story.
- Call (213) 577-1366. The phone is answered 24 hours a day, 7 days a week. Tell us where the car is, its make, model and year, and what you have: no keys, one key, or a key that's failing.
- We work out what the vehicle needs. Based on what you tell us, we explain whether it's likely a cut-only key, a chipped key that needs programming, a remote-head key, or a smart key. We say honestly if it's a model where we need to check the VIN before committing, or where the dealer may be the only route.
- A technician comes to the car in a mobile van. You don't tow it, and you don't have to get it anywhere.
- We verify ownership. Before cutting or programming anything, we ask for proof that the vehicle is yours, typically photo ID and registration or title that matches the car. This protects you. A locksmith who makes keys for any car without asking is a risk to every owner.
- We confirm the exact key by VIN and by inspecting the vehicle, then cut the blade if it has one.
- We program the key to the car and test it. That means checking that it opens the doors, turns the ignition and starts the engine, and that the remote functions work if the key has them.
- We hand you the key or keys, explain what was done, and give you the price before you pay, the same price we quoted once we'd seen the car. If a spare makes sense while we're already there, we'll offer it, and you can say no.
What affects the cost of car key replacement?
We don't print prices on a web page, because the honest answer to what a car key costs is that it depends on the car. We'd rather explain what moves the cost than quote a figure that won't match your vehicle. Once we know the make, model, year and your situation, we can give you a clear quote before any work starts.
The biggest factor is the type of key. A basic cut key is a very different job from a chipped key, and both are different from a push-button smart key. The more electronics in the key, the more the part itself costs and the more programming it takes.
The second factor is whether you have a working key. Making a copy from a working key is usually the lighter-cost route. Starting from nothing, a true all-keys-lost situation, requires more steps to identify the key and program it, and that typically makes the job larger.
Other things that shape the price:
- The vehicle itself. Some makes and model years are straightforward to key. Others use tighter security, and a few can only be keyed by the dealer. We tell you which camp yours falls in.
- Whether the key has a remote. A key with lock, unlock and trunk buttons costs more to supply and program than one without.
- How many keys you want. Making a second key during the same visit is usually more economical than calling us back later, since the equipment is already connected to your car.
- Where and when. A van coming to you at night, or a long way from our base, is a different trip from a daytime visit nearby. We factor that in openly rather than burying it.
- Whether something else is wrong. Occasionally a key that won't work turns out to be an ignition or lock problem rather than a key problem. We tell you if that's the case, and the work changes accordingly.

Call (213) 577-1366Can you get same day car key replacement?
Often, yes, and that's the point of coming to you. Because we cut and program on site, a lot of key jobs can be finished in a single visit, which is what most people mean by same day car key replacement. Our phone is answered around the clock, so a late-evening call gets the same attention as a morning one.
What we won't do is promise a timeframe we can't control. Whether a key can be completed on the spot depends on the vehicle, and on whether we can get the right key blank or fob for it. Most common keys we can handle in the van. A less common one may need to be sourced first, and a few vehicles are dealer-only. If your situation is one of those, you'll hear it from us on the first call, not after we've arrived.
If you're stranded and need the car now, say so when you call. We'll tell you straight whether we can complete the job at the vehicle, and if it can't be finished immediately, what the realistic next step is. If your problem is only that you're locked out and the keys are inside, that's a different and usually quicker job; see our car lockout service.
Spares, duplicates and car key cutting: why do it before you need to?
A duplicate car key made while you still have a working one is the simplest version of this work. The existing key gives us a pattern to follow, there's no scramble, and you walk away with a spare you can keep somewhere sensible. A spare car key is cheap insurance against a bad day. Compare that to an all-keys-lost call, which is more involved and usually more expensive.
Think about where a spare would help most. Keep one at home in a place the household knows. Consider whether a trusted family member should hold one. Avoid hiding one on the car itself, since those spots are the first place anyone looks.
It's also worth checking the key you already have. A blade that's visibly worn, a case that's cracked or a fob that works only some of the time are early warnings. Having a fresh key made from a key that's still functioning is much less trouble than waiting for it to fail completely.
A word of caution on copies: not every key can simply be copied like a house key. Many modern car keys carry electronics that have to be programmed to the specific vehicle, so a blade cut at a hardware counter might turn the lock but won't start the car. We tell you which type you have before we start. If you're after a plain house or office key rather than a car key, that's a separate matter handled by our key duplication work.

Call (213) 577-1366Why call Wilshire Lock & Key for your car key?
There's no secret to what we offer. It's a handful of plain things, and you can judge them yourself.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith who comes to your vehicle about their license before they begin. Asking is normal, and a legitimate company won't be bothered by it.
- We've been in business since 1987. That's a long time of cutting keys, programming vehicles and learning which jobs are simple and which are not.
- We have a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. If you want to bring a key or a question in person, there's a place to do it.
- One company, no dispatch middlemen. The person who answers the phone is part of the company doing the work, so what you're told at the start is what happens at your car.
- David, the owner and lead technician, oversees the work. That means someone with a stake in the result is responsible for how the job is done.
- Phones are answered 24 hours a day, 7 days a week, year-round, including nights, weekends and holidays.
- We serve 140 cities across Los Angeles and Ventura counties, and La Cañada Flintridge is one of them. You can read more about our work in La Cañada Flintridge or see the full list on our locations page.
What should La Cañada Flintridge drivers know about car key replacement?
La Cañada Flintridge sits about 22 miles from our Westwood base, and we serve all of ZIP code 91011. The town's layout shapes how car key jobs tend to go, so here is how it plays out in practice.
Start with the properties. Much of the housing is single-family, with large lots, long driveways and detached garages, and in parts of Flintridge there are estate perimeter gates. If your car is parked behind a driveway or estate gate and you've lost the key, tell us when you call how we get through the gate. Whoever lives there may need to open it, or give us a code. A key job is only as smooth as the access to the vehicle, and we'd rather sort the gate out on the phone than at the curb. If the gate lock itself is the trouble, that's a separate service from the key, and we can talk about that too.
In Alta Canyada and the Paradise Canyon area, houses can sit well back from the road or up a slope. Describing exactly where the car is, in the garage, on the driveway or on the street below, helps us plan the visit. The same goes for the Foothill Boulevard corridor near the town center, where you might lose track of keys while running errands. Tell us which lot or street you're on, and which side of the boulevard.
The setting matters too. La Cañada Flintridge is a foothill community with the Angeles Crest Highway (SR-2) gateway at its edge, and it runs hotter and windier than the basin when the Santa Ana winds blow. Keys get lost on drives up the mountain road, at Descanso Gardens, at Memorial Park, around Flintridge Preparatory School drop-offs and at work near JPL, as they do anywhere people park and walk. If you've misplaced keys somewhere away from home, give us the car's location and we'll plan the visit around that.
Since heat and constant use are hard on plastic cases and worn blades, a spare made before the key fails is a sensible habit here. Many households in town have several drivers and several cars. A spare for each, kept in a place the family agrees on, saves a lot of phone calls later.

Call (213) 577-1366When is another service the better fit?
Not every key problem is a key replacement problem, and we'd rather point you to the right service than sell you the wrong one. A few common mix-ups:
If the key turns but the car won't start, or the key won't turn at all, the trouble may be the ignition rather than the key. We cover that under ignition repair and ignition key replacement, and a good tech will check before cutting a new key that won't fix anything.
If the key works mechanically but the chip isn't being recognized, or you need a key learned to the car, the right page is transponder key programming.
If you need a locksmith to come to you for something beyond keys, our mobile locksmith page explains how the vans work. And if you're still deciding, just call (213) 577-1366. We'll talk through your situation and tell you honestly which service fits, even if the answer is that the dealer is the better route.
Frequently asked questions
Can you make a new car key if I've lost all of my keys?
In most cases, yes. We identify the exact key your vehicle uses by VIN and inspection, cut it if it has a blade, and program it to the car. We'll ask for proof of ownership first. A few vehicles can only be keyed through the dealer, and we tell you that honestly when we know it.
Do I need to tow my car to get a replacement key?
For most jobs, no. Our mobile vans carry cutting and programming equipment, so we work at your vehicle in your driveway, on the street or in a parking lot. If your particular car needs dealer-only work, we'll say so and explain your options.
What do I need to show you before you make a key?
We ask for proof that the vehicle is yours, typically photo ID plus registration or title matching the car. It's a protection for you and for every other owner, because a locksmith who skips this step is making keys for anyone who asks.
How much does car key replacement cost?
It depends on the vehicle, the type of key, whether you have a working key to copy, how many keys you want, and where and when we're coming out. Once we know the make, model, year and your situation, we give you a clear quote before any work begins, and you decide then.
Is a spare car key cheaper than replacing a lost one?
Usually the more economical route is a spare made while you still have a working key. An all-keys-lost job involves more steps. The exact difference depends on your vehicle, which is why we quote after we know what car it is.
Can you get same day car key replacement in La Cañada Flintridge?
Many jobs can be finished in one visit because we cut and program on site. We can't promise it for every vehicle, since some keys need to be sourced and a few cars are dealer-only. We'll tell you plainly on the first call which situation you're in.
Will a key cut at a hardware store start my car?
Not necessarily. Many modern car keys contain electronics that must be programmed to the vehicle, so a blade that turns the lock may still not start the engine. We confirm what your car uses by VIN and in person before we cut anything.
My car is behind a gate on a long driveway. Can you still help?
Yes. Tell us when you call how we get through the gate, whether someone can open it or whether there's a code. Gated driveways are common in parts of town, and sorting access out on the phone keeps the visit simple.
Should I ask a locksmith about their license?
Yes. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith who comes to your car about it before work begins. A legitimate company expects the question.
