What counts as lost all car keys, and what happens next?
Lost all car keys means exactly what it sounds like. There is no key in your pocket, no spare in a kitchen drawer, and no second fob with a family member. The car is parked, probably locked, and nothing you own will start it. That is a different job from copying a key you still have, and it is a different job from a plain lockout. When there is no original to work from, the key has to be made from scratch, using information from the car itself instead of a sample.
People in this spot tend to go through the same thoughts in the same order. It must be in the car. It must be wherever I stopped last. I'll sort it out tomorrow. Those thoughts are reasonable, and sometimes they even work out. But once you have retraced your steps and the key still has not turned up, replacement is the next move, and the sooner you know your options, the less time your car sits where it is.
If you still have one working key and only want another, that is a lighter job, and it is covered on our page about car key replacement in Agoura Hills. This page is for the situation where every key is gone.
How do we make a replacement car key without the original?
A replacement car key without the original is routine work for an automotive locksmith, but it is not one-size-fits-all. What the car needs depends on its make, model and year, and that is why the first few minutes of the conversation are about the vehicle and not about scheduling. Here is how a typical job goes from your first call to a car that starts.
- You call (213) 577-1366. Someone from our company answers, at any hour, and asks for the year, make and model, and exactly where the car is parked.
- We confirm the vehicle and that it is yours. That means the VIN, which is visible at the base of the windshield or on the driver's door jamb, plus your registration or title and a photo ID. We ask every time, and it protects you as much as it protects us.
- We tell you plainly what your car needs: a basic cut key, a key with a security chip, a remote-head key, or a push-button smart key. We also tell you whether we can handle it ourselves or whether your car is a dealer-only case. Where the information is unclear, we confirm by VIN before anyone drives out.
- One of our mobile service vans comes to the car, so the car does not have to be towed anywhere.
- We cut the new key. Depending on the vehicle, that is done from the vehicle's key code or by working from the car's own lock, since there is no old key to copy.
- We program the new key so the car recognizes it, where the vehicle requires that. Depending on the car, we can also talk with you about removing the lost keys from the car's memory so a missing key is not a loose end. We confirm what is possible for your vehicle by VIN.
- We test everything with you standing there: the door lock, the ignition or start button, and any remote buttons. You do not leave until the key does what a key should do.

Call (213) 577-1366What should you have ready when you call?
You do not need everything on this list to get started, and a call is fine even if you are missing half of it. But the more you have, the cleaner the job goes.
- Year, make and model of the car, and trim level if you know it.
- The VIN. If you cannot get to the car, it is often on your insurance card or registration.
- Proof the car is yours: registration, title, or an insurance card, plus a photo ID that matches.
- The exact location, including a parking level, a nearby cross street, or a gate or entry we should know about.
- Whether the car is locked, and whether any alarm has gone off.
- Whether you want one new key or two. Making a spare in the same visit is usually the more economical route compared with doing it later.
How much does lost car key replacement cost in Agoura Hills?
We will not throw out a figure before we know your car, because a number that ignores the vehicle would only be a guess. What we can do is tell you honestly what moves the cost up or down, so nothing about the quote surprises you.
Before we start cutting anything, we explain what the job involves and how the cost will be put together. If something changes midway, we tell you before continuing, not after.
- The vehicle. Make, model and year decide what kind of key is involved and how involved the programming is.
- The key type. A basic cut key, a chipped key, a remote-head key and a smart key are very different pieces of hardware.
- How the key can be cut. Some jobs work from a code tied to your VIN, and others take more hands-on work at the lock.
- Programming complexity. Some cars accept a new key readily, and others need more equipment and more time.
- Whether your car is dealer-only. In those cases, we say so up front instead of pretending otherwise.
- How many keys you want made. A second key during the same visit is usually lighter on cost than a separate trip.
- The hour. Late-night and holiday calls take more of our team's time than a daytime appointment.
- Where the car is. Agoura Hills is about 28 miles from our Westwood storefront, and our vans travel to you, which is part of the picture.
- Related damage. If a lock or ignition has been forced or is worn out, that is separate work from the key itself.

Call (213) 577-1366Locksmith or dealer for a lost car key?
Both are real options, and which one makes sense depends on the car. A dealer can handle lost-key cases, but the car typically has to be brought there, which can mean a tow and working around the dealership's schedule. A mobile locksmith comes to you at any hour, which is why a locksmith is often the more economical and less disruptive route when you are stranded.
That said, we will not oversell. Some vehicles, particularly certain makes or newer model years, may be dealer-only for a lost-key replacement, or may need parts or codes that only the manufacturer releases. Our data on specific vehicles is not always complete, and where it is unclear we say so and confirm by VIN or in person instead of promising something we cannot be sure of. If your car turns out to need the dealer, we will tell you before you pay for a trip, and you will know where you stand.
Newer keys with remote functions are their own category. If what you really need is the remote part of the key, our page on key fob replacement goes into those. For how a chipped key gets paired to the car's computer, see our explanation of transponder key programming.
Is it really a lost key, or something else?
It is worth a few quiet minutes of checking before you assume the worst, because the right fix depends on the actual problem.
If the key is visible inside the car, or you know you locked it in, you do not need a new key at all. That is a car lockout, which is a faster and lighter job than making a key from nothing. If you have the key but the ignition will not turn, or the key will not come out, the trouble is in the car, not the key, and that is a job for ignition repair. And if your car key shares a ring with your house keys, think about where that ring may have ended up. If there is any chance it is in someone else's hands, lock rekeying at home is worth discussing once your car is sorted.
If you think the key was stolen and not just misplaced, say so when you call. We will talk through what that means for your car and what to do about the keys that are still out there.

Call (213) 577-1366What should you know about locksmith licensing?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. You should ask any locksmith who is about to work on your car for that license number, and you should expect a straight answer. That is a fair question for us as well as anyone else. A locksmith who dodges it is telling you something.
Also be wary of a company that answers with a generic name, cannot tell you where they are based, or gives you a very low number on the phone that grows once they arrive. We would rather you ask a few pointed questions and feel confident than hand your car over on a hunch.
Lost car keys around Agoura Hills: from Old Agoura to Lake Lindero
Agoura Hills sits along the Ventura Freeway corridor, mostly in the 91301 ZIP code, and we cover all of it with mobile vans, from Old Agoura out to Liberty Canyon and across Morrison Ranch, Lake Lindero, Fountainwood, Forest Cove, Hillrise and Annandale. The city is about 28 miles from our Westwood storefront, so we plan the trip as soon as we know where the car is.
Where the car is parked matters more here than you might expect. In Old Agoura, with its larger equestrian lots, it is easy to see how a key could get set down in a barn, a tack room or near a pasture gate and never make it back to a pocket. The car might be on a long driveway or a gravel pull-out, and we will plan for that when you tell us how to find you. In HOA communities such as Lake Lindero and Morrison Ranch, mention any entry gate or guest parking arrangement when you call so we can get to the car without delay.
Near Whizin Market Square and along the Kanan Road and Thousand Oaks Boulevard corridors, the call is more likely to be a car in a shopping or office lot, with someone standing next to it and no key. If your keys went missing on a hike near Ladyface Mountain, at Chumash Park, or on the way to Paramount Ranch, think about whether the keys might have been left in a trailhead lot and check there. If you do not find them, we will come to wherever the car is waiting.
Agoura Hills summers are hot and dry, and a locked car in direct sun is a real concern if there is a child or a pet inside. Tell us right away if that is the situation, because it changes how we handle the call. If the key is visible inside and nobody has to be rescued, our mobile locksmith service can usually get you moving without a new key.

Call (213) 577-1366After you have the new key
Once the car is running, the best thing you can do is get a spare made before you lose the next one. A spare made while we are there, or soon after, is a lighter job than starting from nothing again, because there is a working key to work from. For copies of keys that already exist, see key duplication.
A few habits help, too: keep the spare somewhere other than the car, take a photo of your registration and VIN for your phone, and give yourself a minute to check your pockets before you leave any parking lot. None of that is exciting, but it prevents the call you are making right now.
Frequently asked questions
Can you make a new car key if I have lost all my keys in Agoura Hills?
Yes, in most cases. We come to your car with a mobile van, verify the vehicle and your ownership, then make and program a new key from scratch. Some vehicles are dealer-only for lost-key cases, and we tell you that honestly after confirming your car by VIN.
Do I need the original key for a replacement car key?
No. A replacement car key without the original is exactly what this service is for. We work from the vehicle's information instead of a sample key, so having nothing in hand is fine.
What proof do I need that the car is mine?
We ask for the VIN, your registration or title, and a photo ID that matches. It is not red tape. It keeps someone else from walking away with a key to your car.
Can you come out at night or on a weekend?
Yes. We answer the phone at (213) 577-1366 around the clock, every day of the year, and our mobile vans serve Agoura Hills as well as the rest of Los Angeles and Ventura counties.
How much does a lost car key replacement cost?
It depends on the vehicle, the type of key, how the key can be cut, the programming involved, how many keys you want, and the hour and location of the call. We explain what applies to your car and how the cost is built up before we start the work.
Will my lost key still be able to start my car after the new one is made?
That depends on the vehicle. For some cars, we can discuss removing lost keys from the car's memory so a missing key is not a worry. We confirm what your car allows by VIN or in person, and we will not promise what we cannot verify.
Is it better to use a locksmith or the dealer?
A mobile locksmith often avoids the tow and the dealership's schedule, so it is usually the more economical route. But some vehicles may be dealer-only for lost keys, and we tell you up front if yours is one of them.
My car key is locked inside the car. Do I need a new key?
Probably not. If the key is simply locked inside, that is a car lockout, and getting the door open is a lighter job than making a key. Call us and we will tell you which one you have.
My house keys were on the same ring as the car key. What should I do?
Sort out the car first, then consider rekeying the home locks if there is any chance the ring ended up with someone else. If it is only lost in your own driveway, you may feel there is less urgency, but we are happy to talk it through.
