What kind of key fob does your car use?
Key fob is a catch-all word, and the type your car uses decides almost everything about the job. A basic remote locks and unlocks the doors. A remote head key folds a metal blade into the same case. A proximity key, usually called a smart key, lets the car sense the fob in your pocket and start the engine with a button. Replacing a push to start key is a different job from replacing a simple remote, and both are different from copying a plain metal key.
Most fobs do two jobs inside one case. The buttons talk to the car's door and trunk electronics, and a security chip tells the engine it's allowed to run. Both usually have to be set up to your specific vehicle. A fob ordered online and left in a drawer is only a blank shell until someone with the right equipment programs it to your car.
Here is how we sort the fobs we're asked about:
- Remote-only fobs: lock, unlock, trunk, and panic buttons, with a separate key that starts the car.
- Remote head keys: a blade and remote buttons in one piece, often with a chip inside for starting the engine.
- Flip keys: the blade folds into the fob body, common on many vehicles.
- Proximity or smart keys: keyless entry and push button start, with an emergency blade hidden inside the fob.
- Spare key fobs: a second working fob made while you still have one, which is the easier situation for everyone.
What happens when a fob fails in Fillmore?
Fob trouble rarely picks a convenient time. The buttons wear smooth or stop responding. The case cracks and the circuit board rattles around inside. The car flashes a key-not-detected message and won't start. Or the fob is simply gone: dropped somewhere, left in a jacket, or lost on a day out.
Fillmore sits inland in the Santa Clara River Valley, where summers are hot and dry. Small electronics and rubber buttons don't love a fob baking on a dashboard, and valley dust finds its way into pockets, key rings, and glove boxes. None of that causes every failure, but it is part of everyday wear here.
Before you call anyone, try the easy things. If the fob works only up close, or the dashboard shows a low-battery warning for the key, a fresh battery may be the whole fix. Check your owner's manual for how to start the car with a weak smart key, because many cars have a spot to hold the fob against. If you have a spare, try it. If the spare works and the main one doesn't, you know the problem is the fob and not the car.
If none of that helps, or the fob is lost, that's when a replacement and programming job makes sense.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366How does key fob replacement and programming work?
Our process is the same whether it's a simple remote or a push-button-start smart key. The details change by vehicle, but the order doesn't.
- You call (213) 577-1366 and tell us the year, make, and model, plus the VIN if you can read it through the windshield. Tell us what you still have: no keys, one working fob, or a fob that's damaged.
- We tell you what type of fob your car takes, whether we can do it at your location, and what will affect the cost, before anyone drives out.
- A mobile van comes to your car in Fillmore, wherever it's parked: a driveway, a workplace lot, a roadside, or a ranch yard.
- We confirm you're the owner or authorized to have the work done. That means matching the registration or ID to the vehicle. We ask everybody, and a locksmith who doesn't ask is a problem.
- If your car uses a metal blade, we cut it. If the fob needs a new transponder or remote board, we use the right one for your vehicle.
- We program the new fob to the car and, where the vehicle allows, remove lost or stolen fobs from its memory so they no longer work.
- We test everything: lock, unlock, trunk, panic, remote start if equipped, and starting the engine. You see it work before we're done.
- We talk through a spare, because having one made now is much easier than going through this again.
Can you make a new fob if I've lost every key?
Often, yes, but it is a bigger job than copying a fob you still have. With no working key, the car has to be told to accept a brand new one, and how that's done depends on the vehicle. Our guide to lost car key replacement covers that situation, and our page on car key replacement explains what we do when the whole key, not just the remote, has to be replaced.
Here is where we stay honest. Some vehicles have security systems that make programming hard or limit it to the dealer, through special codes or tools we can't reach. We don't have verified information for every year and model, and we won't guess from a make's reputation. We confirm by VIN, and in person if needed. If the dealer is the only route for your car, we say so on the phone, not after you've waited for a van.
If your key has a chip but no remote buttons, that's a related job we handle under transponder key programming. A remote head key is partly that and partly remote, and we'll tell you which parts of it we're replacing.

Call (213) 577-1366What affects the cost of a key fob replacement?
We don't quote numbers on a web page, because the same word, fob, covers a huge range of hardware. What we can do is tell you what moves the cost, so the estimate you get on the phone makes sense.
- The type of fob: a simple remote is a different part from a smart key with proximity sensing and push button start.
- Your vehicle's year, make, and model, since that decides the part, the programming method, and the equipment needed.
- Whether you have a working key to copy from, or whether every key is lost and the car has to be set up from scratch.
- Whether a metal blade has to be cut, and whether it's a high-security cut.
- How many fobs you need programmed. Adding a spare during the same visit is usually the more economical route compared with a second trip later.
- Where the car is and when you need us. Service at night or a long distance from our base can affect the total, and we'll say so up front.
- Whether the vehicle is a dealer-only case. If it is, we'll tell you plainly, and you won't pay us for something we can't do.
Why call Wilshire Lock & Key for a key fob?
Wilshire Lock & Key has been in business since 1987. We run a storefront at 10740 Wilshire Blvd in Westwood and send out mobile service vans, so there's a real shop behind the van that shows up. When you call, you reach us, not a dispatch center that sells your job to whoever picks it up. It's one company from the phone call to the finished fob.
David, the owner and lead technician, oversees the work. Automotive jobs are the kind where being honest early saves everyone time: he'd rather tell you a car is dealer-only on the phone than send a van that can't finish the job.
Our phone is answered 24 hours a day, 7 days a week, all year, at (213) 577-1366. If you want a broader look at what we do for vehicles, our automotive locksmith page covers it, and our mobile locksmith page explains how the vans work.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work. That includes us.
Key fob help around Fillmore, from Central Avenue to Piru
We serve Fillmore and the surrounding valley, including ZIP code 93015. Our storefront is in Westwood, about 55 miles from Fillmore, so we don't pretend we're around the corner. What that means in practice is that the details you give us on the call matter. The right fob, blank, and programming equipment need to be in the van before it leaves, and a VIN gets us there with the right gear.
In Downtown Fillmore, around the Central Avenue district, a fob problem usually shows up at the curb: someone parks near the shops, comes back, and the car won't recognize the key. We come to the car. The same goes for North Fillmore and the Heritage Grove area, where people more often have a car in a driveway and a dead or lost fob inside the house or garage. If you're also moving into one of the newer homes and sorting out which keys went missing in the move, we can talk about lock rekeying for the house as a separate visit.
Out around Bardsdale and Piru, and on the citrus ranch properties on the valley floor, a key ring often holds a truck fob next to gate and outbuilding keys. Lose the ring and you may have two problems at once. We handle the vehicle fob, and for the ranch gate, our gate lock repair page covers that side of it. A ranch yard is a perfectly good place to program a fob, as long as the vehicle is parked where we can work on it.
If you lose a fob out at Sespe Creek, the Fillmore Fish Hatchery, or Elkins Ranch Golf Course, tell us where the car is when you call. We can come to a parking area just like a driveway, and we'll ask you for a good landmark so the van isn't hunting for it.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366Should you get a spare fob before you need one?
Yes, and not just because we sell the work. Making a fob from an existing working key is the easy case. Making one when every key is gone is more involved, and it usually costs more and takes more steps. A spare made now is often the more economical route compared with an emergency later.
A few habits help a fob last in a hot, dusty valley. Keep the spare somewhere cool and dry at home, not in the car. Replace the battery when the car starts giving you a low-battery message instead of waiting for it to die. Don't leave fobs in a hot cab all afternoon, and keep them out of water. If a fob has been through the wash or a pool, don't keep pressing the buttons. Let us look at it.
If your car's keyway or ignition has become hard to turn, don't blame the fob first. That can be a worn ignition, and our page on ignition repair explains how we tell the difference.
What should you have ready when you call?
A little information makes the phone call quick and the estimate accurate. If you can't find all of it, call anyway. We'll work through it with you.
- Year, make, and model of the vehicle, and trim or engine if you know it.
- The VIN, visible through the windshield at the driver's side corner of the dashboard, or on your registration or insurance card.
- What kind of key you have now: push button start, flip key, a remote and separate key, or a plain key.
- How many working keys or fobs you still have, even a worn one.
- Where the car is parked, and whether we can get to it.
- Registration or ID that matches the vehicle, for when we arrive.
- If the car is locked with the fob inside, say so. A car lockout may come first.
Frequently asked questions
Can you replace and program a key fob at my home or workplace in Fillmore?
In most cases, yes. Our vans bring the equipment to the car, so you don't have to tow it or arrange a ride. Whether we can finish the job on site depends on your vehicle, which we confirm by VIN. If the car is a dealer-only case, we'll tell you on the phone.
Do I have to go to the dealer for a new key fob?
Not always. Many fobs can be replaced and programmed by a locksmith with the right equipment, and our service comes to you. Some vehicles do have dealer-only requirements, and we're honest about that. Give us your VIN and we'll tell you which category your car falls into.
Can you program a fob I bought online?
Sometimes. Fobs sold online vary in quality, and some are the wrong frequency or chip type for the car. Call us before you buy, or before we start, and we can tell you whether yours will work. If we supply the fob, we know it matches your vehicle.
What if I've lost every key to my car?
We can often still help, though it is more involved than copying a working fob. Whether it can be done by us or only at the dealer depends on the vehicle. Our page on lost car key replacement walks through the process.
Will my old, lost fob still work after the new one is programmed?
Where the vehicle allows it, we erase lost fobs from the car's memory during programming, so the old one stops working. That matters if the fob was stolen or lost somewhere you can't retrieve it. We'll tell you whether your car supports it.
What proof do you need that the car is mine?
We'll ask for ID and a registration or other document tying you to the vehicle. We ask every customer. It protects you, and it's how a reputable locksmith avoids making keys for a car that isn't yours.
How long does a key fob replacement take?
It depends on the fob type, the vehicle, and whether we're making a first fob from a working key or starting from none. A simple remote is quicker than a smart key on a car with no keys left. We'll give you a realistic idea on the phone once we have your VIN.
Do you serve Bardsdale, Piru, and the ranch areas outside Fillmore?
Yes. We serve the valley around Fillmore, including Bardsdale and Piru. Give us a clear description of where the vehicle is, such as a ranch gate or a nearby road, so the van can find it. Our base is about 55 miles away, and we'll be upfront about how that affects scheduling and cost.
Is Wilshire Lock & Key a licensed locksmith company?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for their license number before work begins, including us. Don't rely on a website's claim. Ask for the number and verify it with the state.
