What does it mean when you've lost all your car keys?
Losing your only key, or the last of several, is a different problem from losing one key out of a pair. With a spare in hand, a locksmith copies it. With nothing in hand, there is nothing to copy, so the new key has to be built from information about the car itself: its VIN, its lock, and its onboard computer. That is what lost car key replacement means, and it is what people are after when they search for a replacement car key without the original.
Many modern cars won't start from a cut piece of metal alone. The engine computer expects to recognize the key before it lets the car run, so the work has two halves: cutting the key to fit the lock, and teaching the car to accept it. In many cases both halves can be done right where the car is parked, which means no tow. Whether yours is one of those cases depends on the year, make and model, and we confirm that by VIN or in person rather than guess.
If you still have one working key, you're in simpler territory. Making a spare from a key you can hand us is key duplication, and a broader overview of replacement options lives on our car key replacement page. This page is for the harder situation: every key is gone, and you need the car to run again.
How do we make a new car key when none of the originals exist?
Here is how a lost-all-keys job goes at Wilshire Lock & Key. The order matters, because the first few steps are designed to keep you from waiting on a van that can't finish the job.
- You call (213) 577-1366 and tell us the year, make and model, and where the car is parked. If you can find the VIN, give us that too. It's visible through the windshield at the base of the driver's side dashboard, on the driver's door jamb sticker, and on your registration or insurance card.
- We tell you what we can and can't do on your vehicle. If it's a case where only the dealer can supply or program the key, we say so on the phone instead of sending a van and finding out later.
- A mobile van comes to the car. We are one company with a Westwood storefront and our own vans, so the technician who arrives works for us, not for a call center that handed off your job.
- Before cutting anything, we check that the car is yours: photo ID, plus a registration or title that matches the vehicle. This is not a formality. A locksmith who makes keys for any car without asking is a risk to every car owner.
- If the car is locked, we get in without damaging it. Entry is its own service, covered on our car lockout page.
- We cut the new key, using the VIN-based code where the data supports it, or by reading the lock itself where it doesn't.
- We program the key to the car's computer. Where the vehicle allows it, we also clear the lost keys from the car's memory so they no longer start it. That matters a great deal if the keys were stolen rather than just misplaced.
- We test everything before we leave: start the engine, turn the ignition several times, run the doors, the trunk, and any remote buttons, and confirm the key behaves the way a factory key would.

Call (213) 577-1366Which kinds of keys can be replaced, and when is it dealer-only?
The key you lost was one of a few types, and the type drives the job. Here are the common ones:
We won't hand you a list of model years that are easy and ones that aren't. Those lists vary by manufacturer and by model, and some of the information floating around online is unverified or contradicts itself. So we confirm by VIN or in person, every time.
There are vehicles and situations where the dealer is the only party that can supply the key or the access needed to program it. When yours is one of them, we will tell you honestly at the start, and your options become a tow to the dealer or a dealer visit arranged on your schedule. We would rather say that on the first call than let you wait for a van that can't help.
- Traditional metal keys with no electronics: the simplest case, usually a matter of cutting a key to fit the lock.
- Transponder keys, which carry a chip the car must recognize before the engine will run. These need programming, which we cover in transponder key programming.
- Remote-head keys, where lock and unlock buttons are built into the key itself.
- Smart or push-button-start keys, where you carry a fob in a pocket or bag. For fob-specific questions, see key fob replacement.
What if the ignition or the lock is part of the problem?
Sometimes the lost key is only half the story. If the car's ignition was already worn, sticky, or hard to turn before the key went missing, a brand-new key may not fix that. We will tell you what we see when we test the ignition. If it needs work, that is a separate job, and our ignition repair page explains how we handle it. We won't bundle it into the key work without telling you.
A key that snapped off in the ignition or a door lock is a different situation from a lost key, and it has its own process. If that's what happened, tell us on the call so we bring the right tools.
One more honest note: if we program a new key and clear the old ones from the car, those old keys stop working for good. So if the missing key turns up in a coat pocket the next day, it will not start the car. For a key that might be stolen, that is exactly what you want. For a key that's probably under the couch, tell us, and we can talk through whether to clear the old ones.

Call (213) 577-1366What affects the cost of lost car key replacement?
We don't quote prices on a web page, because the honest answer depends on your car. What we can do is show you what moves the number, so the quote you get on the phone makes sense.
A mobile locksmith visit is often the more economical route compared with towing the car to a dealer and waiting for a shop appointment, but that depends on the vehicle. For some cars the dealer is the only route, and then the comparison doesn't apply. We tell you which situation you're in before we start, and we explain the quote before any work begins.
- The make, model and year, because the key technology and the programming process differ from one vehicle to the next.
- The key type: a plain metal key, a transponder key, a remote-head key, or a smart key are very different amounts of work and parts.
- How many keys you want made. A spare cut at the same visit is usually easier than coming back later.
- Whether the car is locked and needs entry before anything else can happen.
- Whether the ignition or lock needs repair on top of the new key.
- Where the car is and what time you call, since a late-night trip across the county is a different job than a daytime one.
- Whether the vehicle is a dealer-only case, in which case our part may be limited to telling you so and pointing you the right way.
Why call Wilshire Lock & Key for lost car keys?
We've been in business since 1987, and we answer the phone at (213) 577-1366 around the clock, every day of the year. That matters for lost keys, because they tend to go missing at the worst hours: late after a shift, on a weekend, when a car is in a lot you can't leave it in.
We are one company: a storefront at 10740 Wilshire Blvd in Westwood, and mobile service vans that go out from it. There is no dispatch middleman taking a cut and sending whoever is closest. David, the owner and lead technician, oversees the work, and he's the reason we won't make a key for a car until ownership is checked.
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. You should ask any locksmith for that license number, and check it, before they touch your car. It is a reasonable thing to ask, and a company that hesitates is telling you something. For the full picture of how our vans work, see mobile locksmith service.

Call (213) 577-1366What does a lost car key job look like around Rowland Heights?
Rowland Heights is in unincorporated Los Angeles County, ZIP 91748, and it's spread across commuter roads, plazas, parks and hillsides. That shapes where a car ends up when the keys don't.
Along the Colima Road, Fullerton Road and Nogales Street corridors, a lot of cars sit in plaza parking and in condo and townhome lots. Colima Road and Fullerton Road in particular have townhome and condo complexes, where a driver might have a car in an assigned space and no key to start it. We come to the car, in the space, and do the work there. In the hillside neighborhoods south of Pathfinder Road, driveways and side gates are often the main way in. A lost car key there can also mean a lost house key if the two shared a ring. Tell us on the call, because rekeying a home lock is separate work, explained on our lock rekey page.
Cars also get stranded at the SR-60 park-and-ride lots. Someone leaves for work, realizes at the end of the day that the keys are gone, and the car is sitting in a lot with no way to start it. For that, we come to the lot, check ownership, and do the work beside the car. If your keys disappeared during a visit to Peter F. Schabarum Regional Park, Pathfinder Community Regional Park, or the Rowland Heights Community Center, it's worth retracing your steps and asking at the front desk before you call, but if nothing turns up, we can meet you where the car is.
One practical point: we are based in Westwood, about 34 miles from Rowland Heights, so a trip out to you is a real drive. When you call, we'll tell you plainly when we can reach you rather than give you a promise we can't keep. Summers here are warm to hot and dry, and many lots and hillside driveways are sun-exposed, so if you're waiting in the heat, mention it. We take that into account when we plan the trip.
What should you do before we arrive?
A few small things make a lost-key job go faster and keep you from repeating steps. None of them are complicated.
- Look once more, properly: pockets, bags, the car's seats and floor, and any place you stopped. It sounds obvious, but a thorough search sometimes saves a service call.
- Gather your photo ID and your registration, title, or insurance card. We need proof the car is yours before we cut or program anything.
- Find the VIN on the dashboard, the door jamb sticker, or your paperwork, and have it ready when you call.
- Park somewhere safe if the car can still be moved, and note the exact address or lot so we can find you.
- Don't try to force the ignition, pry the steering column, or hot-wire anything. Those attempts turn a key job into a repair job.
- If the keys might have been stolen, say so. Clearing the old keys from the car's memory becomes a priority, and you may also want to file a report.
- If the car is locked and you're stuck outside it, start with our car lockout page or just tell us on the phone, and we'll sort out entry first.
Frequently asked questions
Can you make a replacement car key without the original?
Yes, in many cases. With no original key, we build the new one from the car's VIN, its lock, and its onboard computer. We confirm whether your specific vehicle can be done in the field by VIN or in person, and we tell you early if it's a dealer-only case.
Do I have to tow my car to the dealer if I've lost all my keys?
Not always. Many vehicles can be keyed and programmed where they're parked, which can save you a tow. Some vehicles and situations are dealer-only, and we will say so honestly instead of promising something we can't do.
Will my old lost key still start the car after you program a new one?
Where the car allows it, we clear the lost keys from its memory so they no longer work. That's useful if the keys were stolen. If you'd rather keep a possibly-misplaced key usable, tell us before we start.
What do I need to show you to get a new car key?
A photo ID and proof the car is yours, such as a registration or title that matches the vehicle. Having the VIN ready speeds things up. We check ownership every time, and that protects you as much as anyone.
How much does lost car key replacement cost?
It depends on the make, model and year, the key type, how many keys you want, whether the car needs to be opened, whether the ignition needs work, and where and when you call. We explain the quote before any work begins, and we'll tell you if the dealer is the only route.
Can you come to a parking lot or park-and-ride lot in Rowland Heights?
Yes. Our vans work at the car, whether it's in a condo space, a plaza lot, a hillside driveway south of Pathfinder Road, or an SR-60 park-and-ride lot. Give us the exact location when you call.
Do you answer calls at night and on weekends?
Yes. We answer (213) 577-1366 24 hours a day, 7 days a week, all year. Lost keys don't keep business hours, so we don't either.
I bought a car and never received any keys. Can you help?
Possibly, but we'll need paperwork that shows the car is yours, usually a title or registration in your name, along with your ID. Without proof of ownership we can't make a key, and we'll explain what you'd need to bring together.
What's the difference between a lost key and a spare key job?
A spare is copied from a key you still have. A lost-all-keys job starts with nothing to copy, so the key is created from the car's data and the lock. If you still have one key, key duplication is the simpler option.
