What does it mean when you have lost all your car keys?
Losing one key is an annoyance. Losing all of them is a different problem, because there is nothing to copy. A spare key can be duplicated by a machine and a little programming. When every key is gone, a locksmith has to build the key from the vehicle's own information and then teach the car to accept it. That is what lost car key replacement is, and it is also what people mean when they search for a replacement car key without the original.
Most modern cars will not start on a plain cut piece of metal. They use a transponder chip, a smart key, or a push-button fob that talks to the car's immobilizer. So the job usually has two halves: getting a key blank cut to fit the locks and ignition, and getting the car's computer to recognize the new key. Either half can be easy or hard depending on the make, the model, and the year.
If you are standing in a Downey parking lot or sitting at home with no keys, the first thing to know is that this is a routine job for an automotive locksmith. It is not a reason to tow the car to a dealer by default, though we will tell you honestly when a dealer is the only route for your particular vehicle.
How do we make a new car key when the original is gone?
Every car is a little different, so the exact method changes. The general sequence is the same, and we walk you through it before any work begins.
- You call (213) 577-1366. We answer around the clock, and we ask for the make, model, year, and where the car is parked.
- We confirm the vehicle by VIN. The VIN tells us which key type, chip system, and programming method apply, so we are not guessing from the model name alone.
- We verify that you are the owner or authorized to have a key made. This protects you as much as it protects us.
- We tell you what your specific car needs and what affects the cost, so you can decide before we start.
- We cut the key. For many vehicles that means cutting from the lock or from key code information rather than from an existing key.
- We program the key or fob to the vehicle so the immobilizer accepts it.
- We test the key in the door, the ignition or start button, and any remote functions, and you watch it work before we pack up.

Call (213) 577-1366What do we need from you before we start?
A new key is access to a vehicle, so we ask a few ordinary questions every time. Having these ready makes the visit faster.
- The vehicle itself, or its exact location. Programming happens at the car, so the car has to be reachable.
- The VIN, which is visible on the dashboard near the windshield and on the driver's door jamb label, plus the registration or title.
- A photo ID that matches the ownership paperwork, or other proof you are entitled to the vehicle.
- The make, model, and year, and anything you know about the keys you had, such as a fob with buttons or a push-to-start system.
- Whether any key is still around somewhere. Even a worn-out or broken key changes the job, so tell us before we start.
Does every car need the dealer when all keys are lost?
No, but some do, and we would rather say that plainly than have you pay for a visit that cannot solve the problem. Whether a locksmith can make a key without the original depends on the vehicle's security system. Some cars let an automotive locksmith read the data and program a new key on site. Others lock that process behind manufacturer-only equipment or codes, and those cases can only be finished through the dealer.
We do not carry a chart in our heads that is accurate for every model year, and key systems change between generations of the same model. That is why we confirm by VIN, and sometimes in person at the car, before we promise anything. If your vehicle turns out to be dealer-only, we will tell you that on the phone or at the car instead of starting a job we cannot finish.
If a dealer is the answer, you still have a decision to make about getting the car there. Some customers prefer to have the car moved and handle the key through the dealership. We can explain what the dealer will likely ask for, such as proof of ownership and the VIN, so you arrive prepared.
What affects the cost of replacing a lost car key in Downey?
We will not quote a number on a web page, because the honest answer depends on your car. These are the factors that move the cost up or down.
Key type is the biggest one. A basic transponder key, a flip key with built-in remote buttons, and a smart proximity key are different parts with different costs and different programming effort. A push-to-start fob is generally more involved than a simple chipped key.
The vehicle's security system matters next. Some systems are straightforward to program; others take more time and specialized equipment. Make and model year change this more than most people expect.
The number of keys you want also counts. Programming a second key during the same visit is usually more economical than calling us back later, because the equipment is already connected and the vehicle is already open to the process. If you are rebuilding your set after losing everything, think about making a spare now.
Location and timing play a part too. A mobile visit to your car involves travel and equipment, and a call in the middle of the night is handled differently than one during normal hours. We tell you how these apply when you call.
Finally, whether the lock or ignition is damaged changes the work. If the ignition is worn or the door lock has been forced, a key alone may not fix the problem, and we will say so before we start.
- Key type: basic transponder, flip key, smart key, or push-button fob
- Vehicle make, model, and year, and its security system
- How many keys you want made during the visit
- Where the car is and when you need us
- Any ignition or lock damage that has to be handled separately

Call (213) 577-1366Where do people in Downey lose their car keys?
Downey is mostly single-family neighborhoods with apartment corridors along streets like Paramount Boulevard, and the lost-key situations we see described to us there are ordinary ones. A resident in an apartment complex along Paramount Boulevard realizes the only key set is missing and the car is in an assigned space. A homeowner in Northeast Downey, where larger custom homes and teardown-rebuild projects are common, has had contractors in and out and cannot find the keys afterward. Someone in Orange Estates, with its older estate-style homes on generous lots, has the car parked in a driveway far from the street and no way to start it.
Other places come up as well. If you are shopping at Stonewood Center or visiting the Columbia Memorial Space Center or the Downey Theatre, a lost key in a parking lot is a stressful way to end the day. People working near Kaiser Permanente Downey Medical Center or PIH Health Downey Hospital sometimes discover the problem at the end of a long shift, and those are the calls where a mobile visit helps most.
Downey's ZIP codes, 90240, 90241, and 90242, all fall within the area we serve, and the neighborhoods from Downtown Downey to Southwest Downey and the Furman Park area are on our regular map. We are based at 10740 Wilshire Blvd in Westwood, roughly 21 miles from Downey, so when you call we tell you plainly how we plan to reach you instead of leaving you guessing.
The climate helps. This is an inland coastal plain with mild winters and warm summers, so weather seldom gets in the way of outdoor key work. On a hot afternoon, we would still suggest finding shade for yourself while we work on the car.
Why call Wilshire Lock & Key for a lost car key?
We have been in business since 1987, and David, the owner and lead technician, oversees the work. You deal with one company, not a dispatch service that sells your call to whoever picks up. We run a storefront on Wilshire Boulevard plus mobile service vans, so key cutting and programming do not have to start from scratch at your curb.
Our phone line, (213) 577-1366, is answered 24 hours a day, seven days a week, year-round. A lost key does not keep business hours, and neither do we.
One more thing worth knowing: California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, a BSIS LCO license. Ask any locksmith you are thinking of hiring for their license number, and check that it matches the company name. It is a reasonable question and a good company will not mind it.

Call (213) 577-1366What should you do right now if all your car keys are missing?
Before you call anyone, take a few minutes to rule out the simple explanations. Check the car's immediate surroundings, jacket pockets, and any place you set things down. If you suspect the keys were stolen or lost somewhere a stranger could find them, treat the car as a security concern and think about whether the registration or any garage access device was with them.
Do not keep trying to force the ignition or the door. Damaging a lock or steering column can turn a key job into a repair job. If the car is simply locked and a key is visible inside, that is a different problem, and our car lockout service covers it. If you need a key made right now, our mobile locksmith service brings the work to the car.
Once you have a new key, have a spare made. It is the lighter-cost way to avoid repeating this, and we explain how key duplication works when a working key is on hand. For a broader look at what we do for vehicles, see our automotive locksmith page.
How does this differ from other car key services?
People often mix up several services that sound alike. Lost car key replacement is the case with no key at all. If you already have a working key and just need another, car key replacement may be the closer fit. If your remote or smart fob has failed or gone missing, key fob replacement covers that part, and transponder key programming handles pairing a chipped key to a vehicle. If the car will not turn over because the ignition is worn, ignition repair is the service to look at.
If you are not sure which of these applies to you, call (213) 577-1366 and describe what happened. We will sort it out with you before anything is booked.
Frequently asked questions
Can you make a car key in Downey if I have no original key at all?
In most cases, yes, but it depends on the vehicle. We confirm the make, model, year, and VIN first, because some security systems allow on-site key creation and a few require the dealer. We tell you which applies before we start work.
How long does lost car key replacement take?
It varies by vehicle. A simple chipped key is quicker than a smart key with a push-button start. We do not promise a set time on the phone, but we explain what your car involves and what to expect on arrival.
Do I have to prove I own the car?
Yes. We ask for photo ID and proof you are entitled to the vehicle, such as the registration or title with a matching VIN. It is a normal step that protects owners from someone else getting a key to their car.
Will I need to tow my car to you?
Often not. Our mobile vans come to the vehicle, and programming happens at the car. Some situations, such as dealer-only systems or a damaged ignition, may change that, and we say so up front.
What if my car turns out to be dealer-only?
We tell you honestly instead of starting a job we cannot complete. We can explain what the dealer will likely ask for, such as the VIN and proof of ownership, so the visit goes smoothly.
What affects the price of a replacement key without the original?
Key type, vehicle make and year, the security system, how many keys you want, and where and when you call. Ignition or lock damage can add separate work. We go over these with you before we begin.
Should I get a spare key made at the same time?
We recommend it. Making a second key during the same visit is usually the more economical route, since the equipment is already connected. It also protects you from having to repeat the process.
Do you serve all of Downey, including ZIP codes 90240, 90241, and 90242?
Yes. We serve Downey from Downtown Downey to Northeast and Southwest Downey, and the surrounding areas. Call (213) 577-1366 and tell us where the car is parked.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for the number and confirm it matches the company name. Also be wary of any caller who will not give a company name or an address.
