What happens when you've lost all your car keys?
Losing the only key to a car is a different problem from losing a spare. If you still have one key, a locksmith copies it. If you have nothing, there is nothing to copy, so the new key has to be created from information tied to the vehicle itself. That is what lost car key replacement means, and it is the work we do: a replacement car key without the original, cut and, where the car requires it, programmed so that it actually starts the engine.
Most people who call us about lost all car keys are in one of two spots. Either they are stranded somewhere with a car they can't open or start, or they are at home after turning the house upside down and checking every jacket pocket twice. Both are normal, and neither is a reason to panic. This is a routine job for an automotive locksmith, and it is usually solvable without towing the car anywhere. We say usually because it depends on the vehicle, and we will tell you plainly at the start if yours is a harder case.
This page explains how the job works, what changes the cost, what we need from you, and what to expect when the van pulls up in Cudahy. If you would rather just talk it through, call (213) 577-1366. The line is answered around the clock, every day of the year.
What kind of key does your car actually use?
The word key covers a lot of ground. Before we can quote the work honestly, we need to know which kind of key your vehicle was built for, because the process and the effort differ quite a bit between them.
We do not guess at this from the phone call alone. Make, model and year give us a starting point, but trims and production changes can mean two cars that look alike use different keys. That is why we confirm by VIN, and in person at the vehicle when needed, before we cut or program anything.
- A traditional all-metal key with no electronics. The simplest case, where the job is mostly about cutting the key correctly.
- A transponder key, where the plastic head holds a chip the car must recognize before it will start. Cutting alone is not enough, and the chip has to be set up with the car. Our page on transponder key programming goes deeper on that side of the work.
- A remote head key or key fob combining a cut blade, a chip and lock/unlock buttons. If the buttons are the main issue, see our notes on key fob replacement.
- A push-button-start smart key, which may not have a conventional blade you insert at all. These are generally the most involved to replace when every key is lost.

Call (213) 577-1366How do we make a replacement car key without the original?
The process is the same in outline every time, with details that shift by vehicle. Here is the sequence we follow, and what it means for you at each point.
- You call (213) 577-1366 and tell us the make, model, year and where the car is. If you can read the VIN off the dashboard plate or your registration, even better. Tell us if the car is locked and whether any key at all, including an old or broken one, still exists.
- We check what your vehicle needs: key type, whether a chip or smart key system is involved, and whether this is a job we can do in the field or one that, for that particular car, only a dealer can complete. If it is dealer-only, we say so right then instead of sending a van.
- A technician comes to the car with the equipment for the job. Our mobile vans are backed by a real storefront at 10740 Wilshire Blvd in Westwood, so the gear and key stock come from our own shop and not from a subcontracted stranger.
- We confirm you are entitled to the vehicle. Expect to show ID and proof of ownership such as a registration or title, and the details should match the car. This protects you. A locksmith who makes a key for any car without asking is a problem for every car owner.
- If the car is locked, we get it open first without damaging the door or lock. Our guide to car lockout service covers that step on its own.
- We create the key. Depending on the vehicle, the blade is cut from the lock or from code information tied to the VIN, and the chip or smart key is then set up so the car accepts it.
- We test the key properly: turn it in the door, start the engine, run any remote buttons, and check that it works more than once. Then you get the key in your hand, and we talk through spares, since making a second key now is far easier than starting from nothing again.
What should you do before you call?
A few minutes of preparation makes the job quicker and the quote clearer. None of this is required to call us, but it helps.
- Look for the VIN on the lower corner of the windshield, the driver's door jamb, or your registration and insurance card. Read it to us, or have the card ready.
- Have your ID and proof of ownership within reach. If the paperwork is in the locked car, tell us. There are ways to handle that, and we will explain them.
- Check the obvious places once more: the last pocket you used, a bag, the spot near the front door, and any spare you gave to a family member or friend. A found key saves you the entire job.
- Note whether the car is in a safe, accessible spot. If it is in a gated lot or deep on a shared driveway, tell us how to reach it.
- If you are not the registered owner, say so on the call. Borrowed and rental cars have different rules, and the owner may need to be involved.

Call (213) 577-1366What affects the cost of a lost car key replacement?
We do not quote numbers on a web page, because a number given without knowing your car would either be wrong or meaningless. What we can do is tell you exactly what moves the cost, so a quote from us, or from anyone else, makes sense when you hear it.
The biggest factor is the key type. A basic metal key sits at the lighter end of the scale. A transponder key needs programming equipment and time. A smart key for a push-button car generally takes the most work. Make, model and year matter because some manufacturers make it simpler for a locksmith to create a key and others make it harder or restrict it.
Beyond that, these things change the price:
- How many keys you want made. A second key made during the same visit is usually the more economical route compared with another call later.
- Whether the car is locked and needs opening first, and whether the locks or ignition are worn or damaged.
- Whether the key can be made on site or the vehicle has to be moved.
- Where you are and what time you call. A night, weekend or holiday call involves different effort than a weekday one.
- Whether any remote functions need to be set up in addition to starting the car.
- Whether the ignition or a lock needs repair before a new key will work properly. A worn ignition can look like a key problem. If that turns out to be the case, our ignition repair service handles it, and we will tell you before doing extra work.
What do lost car keys look like in Cudahy?
Cudahy is a small, dense city, and the way it is built shapes how these calls go. A lot of the housing sits on the long, narrow parcels the city is known for, the so-called Cudahy lots. A front house often has several rental units behind it, joined by one long shared driveway, sometimes with a gate. For lost car key replacement that matters in a simple, practical way: your car may be parked at the back of a deep lot, well away from the street, and the technician needs a clear path to it. If you are in a rear unit off a shared driveway near the Clara Street corridor, or tucked behind a house on the Santa Ana Street side, tell us on the call how to get the van in and who can open the gate.
The same layout means many Cudahy households are renters, and a lost key sometimes comes with a second question: did the key ring also carry the house, unit or mailbox keys? A car key lost on the same ring as a front door key is a bigger worry than one car key alone. We can handle the vehicle side here, and if the ring also carried unit keys, the home-side rekeying is a separate job that your landlord or we can take care of. Landlords managing front-and-back parcels can read about our locksmith services for landlords.
We work across 90201, from the Atlantic Avenue corridor to the Lugo Park area off Otis Ave and out toward the LA River edge in the southeast. The ground is flat and the climate is mild inland plain, so there is nothing about the setting that complicates key work. Our base in Westwood is about 16 miles away, which is why we run mobile vans and not ask you to come to us. A technician brings the equipment to the car wherever it sits in Cudahy.

Call (213) 577-1366Why call Wilshire Lock & Key for a lost key?
We have been in business since 1987. That is long enough to have seen most of the ways a car key goes missing and most of the ways a replacement can go wrong. We are one company with a storefront at 10740 Wilshire Blvd in Los Angeles and our own mobile vans. When you call (213) 577-1366, you are not reaching a national call center that sells your job to whichever contractor answers. That arrangement is where surprise pricing and no-show technicians tend to come from.
David, the owner and lead technician, oversees the work. If a vehicle is unusual or a job does not go the way it should, it lands with someone who answers for the result, not a dispatcher who has never seen the car.
We will also be straight with you about limits. Some vehicles can only have keys made through the dealer, and if yours is one of them we will say so, not start a job we cannot finish. If the information on a vehicle is unclear to us, we say we need to confirm by VIN or in person, and we do exactly that. And we serve 140 cities across Los Angeles and Ventura counties, so after-hours calls are routine for us. For other work on the same vehicle, see the full range of our automotive locksmith services.
How can you check that a locksmith is legitimate?
Car key work is a field where a few bad operators give the trade a poor reputation, so it is worth knowing how to protect yourself. California requires locksmith companies to hold a Locksmith Company license, known as an LCO license, from the Bureau of Security and Investigative Services (BSIS). Ask any locksmith for it, including us, and check it before work begins.
Beyond the license, a few signs point the right way. A real company gives you the business name when it answers and tells you what is needed to quote the job. It asks for proof you own the car before making a key. It explains what will drive the final cost before the work starts. It arrives in a marked vehicle. If a caller will not give a straight answer about the process, or avoids saying who will show up, that is worth noticing.
When is a different service the better fit?
Not every key problem is a lost-key problem, and sending you down the wrong path wastes your time. If you still have a working key and only want another, you need duplication or a spare, which is much simpler and lighter in cost than creating one from nothing. If you want an overview of the general service, see our car key replacement page.
If you can see your key inside the locked car, that is a lockout, not a lost key. If the key snapped off in the ignition or door, the first job is removing the piece, and we cover that elsewhere. If your key turns but the car will not start, or the key sticks and will not turn, the ignition may be the problem. And if you need us at a place that is not a standard address, our mobile locksmith page explains how the vans work. Calling us at (213) 577-1366 gets the sorting done in one conversation.
Frequently asked questions
Can you really make a car key if I have no key at all?
Yes, in most cases. We create the key from information tied to the vehicle, not from a copy, and set up a chip or smart key if the car needs one. Some vehicles can only have keys made through the dealer. If yours is one of those, we say so on the phone.
Do I need to tow my car to the dealer to get a new key?
Often you do not. Our vans can do much of this work where the car is parked in Cudahy. Some makes and models are dealer-only, and we confirm by VIN or in person before saying either way, so you do not pay for a tow you did not need.
What do I need to show you to prove the car is mine?
Photo ID and proof of ownership, such as a registration or title. The name and VIN should match the vehicle. We ask every time. It protects you, because it stops anyone else from having a key made to your car.
Can you tell me the exact price over the phone?
We can explain what affects it, which is key type, make, model and year, number of keys, whether the car is locked, and time of day. A firm quote needs your vehicle details. Be cautious of anyone who quotes a fixed figure without asking what car it is.
Will the old lost key still start my car after you make a new one?
It depends on the vehicle. On many cars the system can be set so that a lost key no longer works, and we can talk through that option during the job. Not every vehicle allows it, so we confirm what your car supports.
My car is parked at the back of a long driveway behind a gate. Does that cause a problem?
Not usually. It is common on Cudahy's deep lots. Tell us when you call how to reach the car and who can open the gate, so the technician can get to the vehicle without delay.
Should I make a spare key while you are there?
Yes, if you can. A second key during the same visit is generally the more economical route compared with a second call later. Having a spare also means a lost key is an inconvenience, not a full replacement job.
Do you answer calls at night and on weekends?
Yes. The line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, and the person on the line is with our company, not a separate dispatch service.
