What do you do when every car key is lost in Chatsworth?
Losing the only key to your car is a bad moment, and losing all of them is worse, because there is no spare to copy and nothing to match against. People in that spot usually ask the same three things: can a locksmith really make a key from nothing, does the car have to be towed, and will it cost more than going to the dealer. The short answers are yes in most cases, usually not, and it depends on the vehicle. The rest of this page explains the reasoning so you can decide with a clear head.
Lost car key replacement is the work we do when there is no original in your hands. The keys might have fallen out of a pocket, gone missing during a move, been left in a rental or rideshare, or disappeared along with a bag. Whatever happened, the job follows the same path: confirm the car is yours, identify exactly what key it needs, cut a new key, and, if the car requires it, program that key so the vehicle accepts it. We do this at the curb, in a driveway, or in a parking lot, using mobile service vans that work out of our Westwood storefront at 10740 Wilshire Blvd. Chatsworth is roughly 26 miles from that base, and it is part of our regular coverage across Los Angeles and Ventura counties.
If your keys are not lost but sitting inside a locked car, that is a different job with a different method, and our car lockout service covers it. This page is for the situation where the keys are simply gone.
How can a replacement car key be made without the original?
A key does not have to be copied from another key. Every key traces back to the vehicle itself: a cut pattern that fits the locks, and on many cars an electronic identity the vehicle expects to recognize before it will start. When the original is gone, we work backward from the car instead of from a key, which is why the process starts with your VIN and a few questions rather than a key blank on a counter.
Here is how a typical visit goes from the first call to the final test.
- You call (213) 577-1366 and tell us the year, make, model, and where the car is parked. We tell you plainly whether we expect to handle it on site or whether your vehicle may be a dealer-only case.
- We verify ownership before any work begins. That means photo ID and paperwork connecting you to the vehicle, covered in the next section.
- We identify the correct key type from the VIN and, where needed, by looking at the car in person. If information is unclear or sources conflict about a particular model, we confirm by VIN or in person rather than guess.
- We produce the key. Depending on the vehicle, that can mean cutting by code or working from the lock itself, so the physical blade turns the door and, where applicable, the ignition.
- If your car uses a chip-based key, a push-button start key, or a remote, the new key is programmed to the vehicle. Our pages on transponder key programming and key fob replacement go deeper on those pieces.
- We test everything before we leave: door, trunk if applicable, ignition or start button, and every remote function you asked for.

Call (213) 577-1366What proof of ownership do you need for a lost car key?
We will ask you to prove the car is yours, and you should be wary of any locksmith who does not. Making a working key to a vehicle is exactly what a thief would want, so a legitimate technician checks first. It takes a couple of minutes and protects you as much as it protects us.
- A government-issued photo ID with your name on it.
- Registration, title, or lease or loan paperwork that matches your name and the vehicle. A photo of the document on your phone is often workable.
- The VIN, which is usually visible through the windshield on the driver's side or on the sticker in the door jamb.
- For company vehicles or cars owned by someone else: written or verbal authorization from the owner, plus the same vehicle details. Tell us up front so we can plan around it.
Which cars can a locksmith handle, and when is the dealer the only option?
We will not promise that every make and model can be done in the driveway, because that would not be honest. Many vehicles can be handled by a mobile locksmith. Some makes and models, and some key types on newer or more tightly secured vehicles, may be available only through the dealer. When that is the case, we say so before you pay for a trip, and we tell you what to bring to the dealer so the visit goes smoothly.
Because chip and programming requirements vary by manufacturer, model, and year, we do not quote general rules over the phone. We confirm by VIN or in person. That can feel slower than a flat answer, but a wrong answer sends you toward a key that will not start your car.
If the key problem is tangled up with a worn or damaged ignition, the new key may turn but the car still will not behave. That is a separate repair, and you can read about ignition repair if it applies. For the wider picture of what we do on vehicles, see our automotive locksmith page. And if you still have one working key and just want a spare, car key replacement is the page you want.
What affects the cost of lost car key replacement?
We do not publish dollar figures on this page because the honest answer depends on your car, and a number printed here would be wrong for many readers. What we can do is show you what moves the cost up or down so the quote you hear on the phone makes sense.
One more point on comparing options. If your car has no key at all, getting it to a dealer usually means arranging a tow, which is a separate bill before the key work even starts. For many vehicles, a mobile visit is the more economical route, though not for every make and model, and we will say so when a dealer is the realistic path.
- Make, model, and year. Keys on some vehicles are simple; others involve security systems that take more equipment and time.
- Key type. A basic metal key, a chip key, a flip key with buttons, and a push-button start key are very different products.
- Number of keys. Most people want a spare made while we are there, and a second key during the same visit is usually easier to arrange than a separate trip later.
- Remote functions. Whether you need lock, unlock, trunk, and panic buttons working changes the work.
- How the key is produced. Some cuts come from the vehicle's code; others require working from the lock, which takes longer.
- Access to the car. If the vehicle is also locked, getting in is part of the visit.
- Time and place. Overnight and weekend calls, and how far the van travels, affect the quote.
- Dealer involvement. If a vehicle is dealer-only, cost depends on what the dealer charges, and we will not pretend otherwise.

Call (213) 577-1366How do lost-key calls play out around Chatsworth, 91311?
Chatsworth, ZIP 91311, is spread out, and where your car sits matters to how we work. In Old Town Chatsworth along the Devonshire Street corridor, cars are usually on the street or in small lots near storefronts, so we can work right at the curb. Around the Stoney Point area and Stoney Point Park, you may be parked near trailheads and rocky ground; if your keys slipped out on a walk, retrace your route and check the lot before assuming they are gone for good, then call us if they are not turning up.
At the Rockpointe townhome community, where shared parking and 1970s-era complexes are common, the awkward case is a key ring that carried both the car key and the unit key. If that happens, you may need new car keys and a rekey for the townhome. We handle the car side here, and a rekey is a separate service; plain-text mention is enough for now, and our lock rekey page explains how that works. Local scenarios like townhome lockouts at Rockpointe are common enough that it is worth thinking about the whole ring when you call.
Toward the Santa Susana Pass foothills and Monteria Estates, the gated equestrian area, properties often sit behind driveway gates with long approaches and detached garages or barns. When you call, tell us how to get through the gate, or arrange for someone to meet our van. That one detail saves a lot of back and forth. Because we run mobile locksmith vans, the work happens wherever the car is, including a barn lot or a side drive.
Two other places worth naming: the Chatsworth Transportation Center area, where commuters who park for Metrolink or Amtrak sometimes come back to find the keys gone, and the De Soto Avenue industrial corridor, where company vehicles and work trucks are common. For company vehicles, the owner's authorization matters, so have that sorted before we arrive.
Climate plays a small role too. Chatsworth is one of the hottest parts of the San Fernando Valley in summer, so if you are waiting beside a sun-baked car, find shade. In fall, Santa Ana winds funnel through the Santa Susana Pass, and wind-blown grit and dust near the rocky foothills can work into exterior lock cylinders over time. On an older vehicle, a gritty door lock can make a new key feel stiff, so we check the door and ignition action while we are there.

Call (213) 577-1366What should you do before you call?
A few minutes of checking can sometimes save you the service call, and a few minutes of preparation makes the call itself go better. None of this is complicated.
- Retrace your steps. Check pockets, bags, the last place you stopped, and anywhere you sat down. Ask anyone who rode with you.
- Look for a spare. A second key at home, with a family member, or with a roommate may solve the problem outright.
- Park somewhere safe if the car is movable, or stay with it if it is not. Do not try to force a door or the ignition. Damage there turns a key job into a repair job.
- Gather your ID, registration or title, and the VIN so verification is quick.
- If you think the keys were stolen rather than lost, consider filing a report, and tell us when you call so we can talk through what that means for the car.
- Call (213) 577-1366. The line is answered around the clock, so there is no wrong hour.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and that time shows up in the details: knowing when to ask another question instead of assuming, and knowing when to say a car belongs at the dealer. We keep a storefront at 10740 Wilshire Blvd in Westwood and run mobile service vans, so there is a real shop behind the van that arrives at your car.
You are dealing with one company, not a call center that passes your job to whoever is free. There are no dispatch middlemen between your call and the technician. David, the owner and lead technician, oversees the work, so questions about a tricky vehicle have somewhere to go. Our line is answered 24 hours a day, 7 days a week, year-round, and we cover 140 cities across Los Angeles and Ventura counties, Chatsworth among them.
We will not hype what we do. We will tell you what we need, what we can do for your vehicle, and what affects the cost before we begin.
How can you check a locksmith before you hire one?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), known as an LCO license. Ask any locksmith for that license number before work starts. A reputable company will give it without hesitation.
A few other signs are worth watching. Be cautious if the person who answers the phone will not give a business name, if no one asks for proof you own the car, or if the quote changes sharply once someone arrives. Lost-key calls are urgent, which is exactly when people skip these checks, so take a minute to ask the questions.
Frequently asked questions
Can you make a car key if I have lost all of them?
In most cases, yes. We work from the VIN and the vehicle itself, not from an existing key. Some makes, models, and key types may be dealer-only, and we tell you that before you commit to anything. We confirm by VIN or in person.
Do I need to tow my car to get a new key?
Usually not. Our mobile vans come to the car in your driveway, a parking lot, or the curb. A tow generally only comes up when a vehicle turns out to be a dealer-only case or has a separate mechanical problem.
Do you need the original key to make a replacement?
No. That is the point of this service. A replacement car key without the original is made from the vehicle's information and, where needed, by working from the locks. You will need proof of ownership, since we are making a working key from scratch.
How much does lost car key replacement cost?
It depends on the make, model, and year, the type of key, how many keys you want, whether remote buttons are needed, how the key is produced, access to the car, and the time and place of the call. We explain the cost before we start, after we know your vehicle.
Will the lost key still be able to start my car?
Whether the old keys can be shut out of the car depends on the vehicle, and we confirm that by VIN or in person instead of giving a general answer. If you think the keys were stolen, tell us when you call so we can go over your options.
Can you come to Chatsworth at night or on a weekend?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. We serve Chatsworth and the rest of ZIP 91311 from our Westwood base with mobile vans.
My car is parked behind a gate near the Santa Susana foothills. Is that a problem?
Not if we know how to get in. Tell us the gate code or arrange for someone to meet the van. Gated and long-driveway properties are common in that area, and a bit of planning keeps the visit smooth.
What if the car belongs to my company or someone else?
We can usually still help, but we need authorization from the owner along with the vehicle details and your ID. Have that ready when you call, especially for work vehicles along the De Soto Avenue corridor.
I lost my house keys and car keys together. What should I do?
Call us and mention both. We handle the car keys here, and your home locks may need to be rekeyed if the ring could be in the wrong hands. We can talk through the order that makes sense.
