What does it mean when you have lost all your car keys?

Losing your only key, or losing the last of several, is a different problem from losing a spare. When a spare still exists, a locksmith can copy it or read information from it. When every key is gone, there is nothing to copy. The new key has to be created from information the car itself holds, and that is a more involved job than most people expect.

The good news is that a replacement car key without the original is a normal, routine part of automotive locksmith work. It does not mean the car is stuck at a dealer, and it does not mean you have to have it towed in every case. It does mean the work has to be done carefully, because a modern key is often two things at once: a cut piece of metal that turns the lock and ignition, and an electronic identity the car has to recognize before it will start.

This page explains how we handle lost all car keys situations for people in Cerritos: what we do, in what order, what changes the cost, and where we will tell you plainly that a vehicle may be a dealer-only case. If you would rather just talk it through, the line at (213) 577-1366 is answered around the clock, every day of the year.

What should you do first if every key is gone?

Before you call anyone, a few calm checks save time and sometimes save the whole job. People are often surprised how many lost keys turn up in the last place they would think to look once they slow down.

  • Retrace your steps from the last time you remember using the key, including jacket pockets, bags, the car's cup holders, and any place you set things down while shopping or eating.
  • Check whether anyone else in your household carries a spare, or whether a spare was ever cut and left with a relative, a roommate, or a former owner.
  • Look at where the car is. If it is parked somewhere safe and legal, there is no hurry to move it. If it is blocking something or parked on a time-limited street, tell us so we can plan around it.
  • Do not try to force the door or the ignition. Forcing either one can turn a straightforward key job into a lock repair or ignition repair job on top of it.
  • Have your vehicle details ready, and have proof you own the car, which we explain further down.

How do we make a replacement car key without the original?

Every car and every key system is a little different, so we confirm details on the call and again at the vehicle. The general order of work is the same, though. Here is how a typical lost car key replacement goes when we come to you in a mobile van, or when you bring the car to our storefront.

  1. You call (213) 577-1366 and tell us the year, make, model, and where the car is. We ask whether any key at all still exists, and whether the car is locked or unlocked.
  2. We confirm what kind of key the car uses. Some vehicles use a plain metal key, some use a key with a transponder chip in the head, some use a remote-head key, and some use a push-button start with a smart fob. This determines the whole job, so we do not guess; we confirm by VIN and by looking at the car in person.
  3. At the vehicle, we verify who you are and that the car is yours. We ask for your ID and for registration or title that matches the VIN. This protects you as much as it protects anyone else.
  4. If the doors are locked, we get you in without damage first. That is its own skill, and our car lockout service covers it when a lockout is all you need.
  5. We cut a new key blade using the vehicle's key code or by working from the lock itself, which is how a key can be made when no original exists.
  6. If the car needs electronic programming, we program the new key so the vehicle recognizes it. Where a car requires it, we add or reset keys so the old, lost key can be removed from the car's memory and no longer starts it.
  7. We test the new key in the door, the ignition or start button, and any remote functions before we call the job finished, and we make a second key if you want one. Having a spare cut now is far easier than going through this again.

Which cars can we do, and when is the dealer the only option?

We will be straight with you here, because this is where some companies oversell. Most vehicles can be handled by an automotive locksmith, but not every make, model, and year is the same. Some newer or more tightly secured systems restrict key creation to the dealer or to manufacturer-controlled processes. Others can be done by a locksmith but need specific equipment or access codes that are only available for certain model years.

We do not make blanket promises about a vehicle before we know what it is. When you call, we ask for the VIN and confirm what the car needs. If your car is a dealer-only case, we tell you so on the phone or at the vehicle rather than letting you wait around or pay for a visit that cannot solve the problem. If a vehicle's information is unclear or conflicting, we say that too and confirm in person.

What we can say in general is this: a transponder key is a key with a chip that talks to the car. A key that is only cut, with no chip programmed, may open the door but will not start the engine on a car that expects a recognized chip. That is why programming is a separate part of the work. You can read more about that side of things on our transponder key programming page, and about smart fobs and remotes on our key fob replacement page.

For the broader picture of how we handle new keys for many vehicle types, our car key replacement page covers the service as a whole. This page is specifically about the case where all the keys are lost.

What affects the cost of lost car key replacement?

We do not publish prices on this page because the final cost depends on your actual vehicle and situation, and a number quoted without knowing those would not be honest. What we can do is explain what moves the cost up or down, so there are no surprises when you get a quote.

On the phone we give you a clear explanation of what the job involves and what your options are. The lighter-cost route is usually a plain or basic transponder key made by a locksmith rather than a full dealer process, and where your vehicle allows it, that is often the more economical route, especially since it avoids towing.

  • Key type. A plain metal key is a simpler job than a transponder key, a remote-head key, or a smart fob with push-button start.
  • Vehicle make, model, and year. Some systems are straightforward to work with and some need more specialized equipment or access.
  • Whether any key exists. Losing all keys means creating a key from nothing, which involves more steps than copying one that still works.
  • Programming needs. Some cars need the new key programmed, and some need extra steps to remove the lost key from the car's memory.
  • Lockout or lock condition. If the doors are locked, or if a lock or ignition is worn or damaged, that adds work.
  • Where and when we come. A mobile visit to your location differs from a visit to our storefront, and after-hours or holiday calls are handled differently than daytime ones.
  • How many keys you want. A spare made during the same visit is usually more economical than coming back later.

Lost car key replacement in Cerritos: where it happens here

Cerritos is a car-centered city, and the way people lose keys here follows its routines. The Cerritos Auto Square district draws people who are test driving, buying, servicing, or comparing vehicles, and the cars involved are often newer ones with chipped keys or smart fobs. Someone who sets a fob down during a visit and drives off with the wrong thing in their pocket, or who is stuck at a lot after the last key goes missing, is exactly the kind of situation where a replacement car key without the original comes up. Our automotive work for shoppers near the Cerritos Auto Square is a real part of what we do here.

Shopping and errands create their own pattern. The Los Cerritos Center area and Cerritos Towne Center have big parking areas where a key can slip out of a bag or a pocket and where a car can sit for hours before anyone realizes the keys are not coming back. If you are standing in a parking lot in ZIP code 90703 with no key and a car that will not respond, we can come to the vehicle rather than asking you to get it somewhere else.

Home is another place keys disappear. Most Cerritos homes are ranch and two-story tract houses built when the old dairy land was developed in the 1960s and 1970s, and they are largely owner-occupied, which means a household often has several drivers and several cars. Keys get shared, borrowed, and lost in the shuffle. In Shadow Park, the gated community with staffed gate access, a locksmith van still needs the gate to clear us, so it helps to tell the gate that someone is coming and to give us the address and your name at the time of the call.

Cerritos Industrial Park and the Civic Center area are workplaces for many people, and employees park all day, so a key lost on a shift can mean a stranded car at the end of it. We can come to a work parking lot as easily as a driveway, as long as you can show the car is yours.

Cerritos is about 29 miles from our Westwood storefront at 10740 Wilshire Blvd, and our mobile vans are how we cover the distance. We do not quote arrival times from this page, since traffic and conditions change them, but we will tell you what to expect when you call. Because the city is inland, summer afternoons run warmer than at the coast, so if your car is sitting in the sun, ask us to prioritize shade or tell us if you have a child or pet situation to handle first.

Why call Wilshire Lock & Key for lost car keys?

Plenty of companies can say they handle lost car keys. Here is what is actually true about us, without dressing it up.

We have been in business since 1987. That is a long time of working on locks, keys, and vehicles, and it means we have seen a wide range of situations and know when to slow down and check. We are one company, not a dispatch service that passes your call to whoever answers. You reach us at (213) 577-1366, and the people handling your job work for us.

We operate a storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans, so we can come to you or you can bring the car in if that suits you better. David, the owner and lead technician, oversees how we work, and that includes being honest when a job is not one we can or should do.

One more thing worth knowing. California requires locksmith companies to hold a BSIS LCO license, which is issued through the Bureau of Security and Investigative Services. You should ask any locksmith for that license number before they start work, including us. We are adding our license number to our materials, and we would rather you ask than assume.

We answer around the clock, every day of the year. Lost keys do not pick convenient times, and our 24-hour locksmith line works the same way for car problems as for any other. If the car is parked where you cannot easily leave it, our mobile locksmith service is how we reach you.

What should you have ready when you call?

A little preparation makes the call quicker and the job smoother. None of this is a barrier; if you are missing something, tell us and we will work out what is possible.

  • Year, make, and model of the vehicle, and trim or engine if you know it.
  • The VIN, which is usually visible through the windshield on the driver's side near the dashboard and is also on your registration and insurance card.
  • Your ID, and registration or title showing the car is yours.
  • Where the car is, and whether it is locked or unlocked, in a garage, a gated area, or a public lot.
  • Whether you want one new key or a spare as well.
  • Whether the car has push-button start or a traditional ignition, and whether it had a remote or fob that is also gone.

When is it a different job than lost keys?

Not every no-key situation is a lost-all-keys job, and we would rather point you to the right service than sell you the wrong one. If you still have a key but it is broken off in the lock or ignition, that is a different job, covered under broken key extraction. If the key goes in but the ignition will not turn, the problem may be the lock itself, which is what ignition repair is for. If you only need a copy of a key you still have, our key duplication service is simpler and more economical than creating a key from nothing.

If you are not sure which one you have, call us. Describing what happened, what the car does when you try the door or the ignition, and what keys you still hold usually tells us quickly. If you want a fuller picture of our automotive work, our automotive locksmith page lays it out. And if the whole situation is part of a bigger lockout or emergency, our main Cerritos locksmith page shows the other services we offer here.

Frequently asked questions

Can you make a car key if I have lost all my keys and have no original?

Yes, in most cases. We create a new key without needing the original, using the vehicle's information and the lock itself. Some vehicles are restricted to dealer-only processes, and we tell you honestly if yours is one of them. We confirm by VIN and in person rather than promising before we know the car.

Do I need to tow my car to you in Cerritos?

Usually not. Our mobile vans come to the vehicle, whether it is in a driveway, a parking lot, or a work location. If your car turns out to be a dealer-only case, or needs work that cannot be done on site, we will tell you that and explain your options.

What proof do I need to show that the car is mine?

We ask for your photo ID and for registration or title that matches the vehicle's VIN. This is standard and it protects you. If you are missing a document, call us at (213) 577-1366 and we will tell you what we can work with.

How much does it cost to replace a lost car key?

It depends on the key type, the make, model, and year, whether programming is needed, whether the doors are locked, where and when we come, and how many keys you want. We do not quote numbers without knowing your car, but we explain what applies on the phone so there are no surprises.

Is a locksmith or the dealer the more economical route for lost keys?

For many vehicles, a locksmith is usually the more economical route, partly because there is no towing and no wait for a dealer appointment. For some makes and years, the dealer is the only option. We will tell you which applies to your car instead of guessing.

Will the new key start my car, or just open the door?

If your car uses a transponder chip or smart fob, the key has to be programmed so the car recognizes it. A cut key without programming may open a door but will not start the engine. We program the key as part of the job where your vehicle needs it and test it before we finish.

What happens to the old lost key? Could someone use it?

On many vehicles, we can program the new key so the car no longer accepts the lost one. Whether that is possible depends on the car, so we confirm it at the vehicle. If you are worried about a key that may have fallen into someone else's hands, mention it when you call.

Can you come to a gated area like Shadow Park?

Yes, but the staffed gate needs to let us in. Give the gate your name and our visit in advance, and give us the address and any gate instructions when you call. We handle gated communities like this regularly, and it helps to have the resident contact the gate.

Can you help if my car is locked and I am stuck at Los Cerritos Center or the Auto Square?

Yes. We come to the vehicle wherever it is parked in Cerritos, including shopping lots and dealership areas. We open the car without damage first if needed, then make the new key. Call (213) 577-1366 and tell us the exact parking area.

Do you answer at night and on holidays?

Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round. Lost keys do not wait for business hours, and neither do we. Timing and conditions can affect how we schedule a visit, and we explain that on the call.
