What happens when you've lost all your car keys?
Losing the only key to your car is a different problem from losing a spare. With a spare in your hand, a locksmith can copy it. With nothing, there is nothing to copy, so the new key has to be built from the car's own information: the VIN, the lock itself, and the vehicle's anti-theft system. That job is called making a replacement car key without the original, and it is regular work for an automotive locksmith. How simple it is depends heavily on the make, model and year.
Most cars built in the last couple of decades will not start with a plain metal key cut to fit the ignition. They carry an electronic component that the car's computer has to recognize. So a lost-key job really has two parts: the physical key, fob or smart key, and the electronic authorization that lets the car accept it. We do both at your vehicle, so you do not have to arrange a tow or wait for a dealer appointment in most cases.
If you are not completely sure every key is gone, take a few minutes to check the obvious places: coat pockets, the bag you carried yesterday, the last place you parked, and anyone else who drives the car. A forgotten spare saves you real money and time. If you have truly checked and there is nothing, that is the situation this page is written for.
What should you have ready before you call?
You do not need to gather everything before dialing (213) 577-1366, but the more of this you have, the faster we can tell you what your vehicle needs. We ask for ownership proof on every lost-key job. A new key is full access to someone's car, and a locksmith who does not ask who you are is one you should be wary of.
- Year, make and model of the vehicle, plus trim or engine if you know it
- The VIN, which is usually visible through the windshield at the driver's side of the dashboard and is also printed on your registration and many insurance cards
- Your photo ID
- Proof the car is yours: registration, title, or an insurance card with your name and the vehicle listed
- Where the car is parked right now, and whether it is locked
- How many working keys you want when we leave, since making a spare while we are already set up is usually the more economical route than a second visit

We answer around the clock, every day of the year.
Call (213) 577-1366How do we replace a lost car key, step by step?
Every vehicle is a little different, but the process follows the same order. We would rather walk you through it than have you guess what is happening in your driveway or parking lot.
- You call (213) 577-1366 and tell us the vehicle and where it is. Someone answers at any hour, any day.
- We confirm the vehicle by VIN and tell you what kind of key it uses, whether we can do the whole job at your car, and whether any part of it is dealer-only.
- We give you a cost explanation based on that key type and situation before we start work, so there are no surprises later.
- At the car, we verify your ID and proof of ownership.
- If the car is locked, we get it open first without damaging the door or lock. If that is your only issue, our car lockout service covers it on its own.
- We cut the new key from the VIN and lock data, or prepare the fob or smart key, depending on what your vehicle uses.
- We program the new key to the car's immobilizer system so it starts the engine, not just turns in the ignition.
- You test everything: door locks, trunk, ignition, remote buttons, and push-to-start if the car has it. We do not leave until it all works the way you expect.
Can a replacement car key really be made without the original?
In most cases, yes. Having no original key is common, and the car's identity information, tied to the VIN, is what allows a new one to be created. The original is only a convenience, not a requirement.
What we will not do is promise that every vehicle can be handled in the field. Some makes and model years lock key creation behind manufacturer systems, and for those we may need the dealer to supply a part of the process, or the entire thing. We will tell you plainly when we confirm by VIN, before you pay for anything, so you can decide whether to use us for what we can do or go straight to the dealer.
The key type matters a lot too. A basic transponder key, a remote-head key, a key fob, and a push-button smart key are four different jobs. If you want to know more about how the electronics side works, read about transponder key programming and key fob replacement. Our general car key replacement service covers situations where you still have a key and just need a spare or a swap. This page is for the harder case, when none are left.

Call (213) 577-1366What affects the cost of lost car key replacement?
We do not publish prices on a web page because the honest answer depends on your car, and a flat number would be wrong for many of the people reading it. Here is what moves the cost up or down so you can judge any quote you get, ours included.
- Key type: a basic cut key, a transponder key, a remote-head key and a smart key are very different in parts and programming effort
- Vehicle make, model and year, since some systems are simple and others need extra security steps or manufacturer access
- How many keys you want made in the same visit
- Whether the lock or ignition needs repair before a new key will work, which is a separate job from the key itself
- Where the car is and what time you call, because after-hours and distance are real factors for a mobile van
- Whether the car is locked and has to be opened first
- Whether we can finish the entire job at the car or part of it has to go through a dealer
Is a locksmith or the dealer the better route for a lost key?
It depends on the car. For many vehicles, an automotive locksmith is the lighter-cost option because the work happens where the car is parked. There is no tow, no waiting for a service appointment, and no being without a vehicle. If your keys are lost at night or on a weekend, that difference is even bigger, since we answer around the clock.
There are cases where the dealer is the right choice, and we would rather say so than pretend otherwise. Certain vehicles need factory-only access for key creation. If yours is one of them, we will tell you when we confirm the VIN. Some customers also prefer the dealer for a warranty-related reason, which is a reasonable preference.
If the ignition cylinder is worn or damaged, a new key may not turn it even when it is cut and programmed correctly. In that case the cylinder, not the key, is the real problem, and ignition repair is the next step. We check for that early so you are not paying twice for the same trouble.
Lost all your car keys in Artesia: where these calls come from
Artesia is a compact city, and the situations we hear about here are ordinary ones. Someone closes up a restaurant or shop along the Pioneer Boulevard international district, Little India, and realizes the key ring is gone somewhere between the register and the car. Someone parks near historic downtown Artesia, around 187th Street and Pioneer, for an errand and comes back to an empty pocket. Someone leaves a car at the Artesia Park area after an afternoon outing, or on the South Street corridor, and cannot find the keys anywhere. In every case the first step is the same: call us, and we confirm the vehicle by VIN.
For shop and restaurant owners, there is a second problem to think about. Pioneer Boulevard businesses often keep the shop key and the vehicle key on the same ring. If that ring is lost, the car is not the only thing exposed. We can replace the car key and, if you want, you can follow up with a storefront lock repair or a rekey so a lost ring cannot open your business. Homeowners in the post-war tracts around ZIP code 90701 have the same issue with the house key. Many of those homes still carry mid-century hardware, so a lock rekey after losing a ring is worth discussing.
Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 29 miles from Artesia, and our mobile vans work across 140 cities in Los Angeles and Ventura counties. That means a van can come to a driveway, a lot near the east edge by Cerritos Towne Center, or a curb on a residential street. Wherever the car is, we do the work there. If you would rather read about our broader service in town, our Artesia locksmith page lists everything we handle here.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987. That is long enough to have seen key systems change from simple metal blanks to computers in the key head, and we kept learning as they did. We are a storefront shop with mobile service vans, so there is a real address behind the phone number and a real team behind the van.
When you call (213) 577-1366, you reach us, not a call center that sells your job to the nearest available contractor. We are one company, with no dispatch middlemen in the chain. David, the owner and lead technician, oversees the work, and that is the person who stands behind how we do things.
One more point worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you are thinking of hiring for that license number before they start work on your car. It is a fair question and a reasonable standard to hold anyone to, including us.
If you want to see what else our automotive team does, see our automotive locksmith page. If the job turns out to need a van at your location, our mobile locksmith service explains how that works.
What should you do after the new key works?
Once you have a working key, do not leave it at one. Having a second key made soon after is the single easiest way to avoid this situation again, and it is much simpler than starting from nothing. A spare duplicated from a working key is a straightforward job, which is where key duplication comes in.
If your lost keys might have been stolen rather than just misplaced, tell us when you call. On some vehicles, the programming process can remove old keys from the car's memory so the lost ones no longer start the engine. Whether that is possible depends on the vehicle, and we confirm it by VIN or in person instead of assuming.
Think about everything that was on that key ring. House keys, a mailbox key, a shop key, a gate fob. Losing a car key is often a good time to review what else could now be in someone else's hands, and to fix it before it becomes a bigger problem.
Frequently asked questions
Can you make a new car key if I've lost every key I had?
In most cases, yes. We build the key from the vehicle's VIN and lock information and program it to the car, so no original is needed. Some vehicles have dealer-only steps, and we tell you that up front when we confirm your VIN.
What proof do I need to show you?
We ask for your photo ID and proof the car is yours, such as the registration, title, or an insurance card with your name and the vehicle on it. We ask every customer, because a new key gives full access to the car.
Will my car need to be towed?
Usually not. Our vans do most lost-key work at the vehicle, wherever it is parked in Artesia. Towing becomes a possibility only if the car has a mechanical problem, such as a damaged ignition, or a dealer-only step that cannot be done in the field.
Is a locksmith less costly than the dealer?
Often it is the more economical route, mainly because there is no tow and no extra trip, but it depends on your vehicle. Key type, programming effort, and the number of keys all affect cost, and we explain it before starting work. We do not quote prices on the website.
How long does a lost-key job take?
It varies with the vehicle and key type. A basic transponder key is a different task from a smart key with push-button start. When you call (213) 577-1366 and we confirm the VIN, we can tell you what to expect for your car.
Can you make a key for a push-button start car?
Often we can, but it depends on the make, model and year. Smart keys use more advanced security than simple keys, and some need dealer involvement. We confirm by VIN before you commit to anything.
Will the lost key still be able to start my car after you make a new one?
Not necessarily removed by default. On some vehicles, programming a new key can erase the old ones from the car's memory, and on others it cannot. If your keys may have been stolen, tell us, and we will confirm what your vehicle allows.
My car is locked and my keys are gone. Can you handle both?
Yes. We open the vehicle first without damaging it, then make and program the new key. If you only need the car opened and still have a key somewhere, our car lockout service is the simpler job.
Do you take lost-key calls at night and on weekends in Artesia?
Yes. We answer (213) 577-1366 24 hours a day, 7 days a week, all year. Evenings, weekends and holidays are included. Timing can affect the cost of a visit, and we explain that when you call.
