Do you need a new key fob, or just a new battery?
A fob that stops working is not always a fob that needs replacing. Before anyone drives out to you, a minute of troubleshooting is worth it. If the buttons only work when you hold the fob right against the door handle, or the dashboard says the key isn't detected, a weak coin battery is the likely cause. Swapping a battery costs far less than a new fob, and we will tell you so on the phone rather than send a van you don't need.
Replacement is the right call when the case is cracked, the button pad is worn through, water got inside, the fob was dropped or run over, or it is simply gone. It is also the right call if you only have one working fob and want a spare before that one disappears too. A spare made while you still have a working key is almost always a simpler, calmer job than starting from nothing.
Heat plays a part in West Covina. This is one of the warmer corners of the San Gabriel Valley in summer, and a fob left on a sunny dashboard or in a hot car can age its plastic case and tire its battery faster than you would expect. If your fob has started to feel flaky in the warm months, treat it as a warning and get a spare made.
What kinds of key fobs can be replaced and programmed?
Cars use several different styles of fob, and what you have decides how the job goes. When you call, it helps to know which of these looks most like yours. If you are not sure, tell us the year, make, and model and we will work it out together.
We confirm the exact fob and programming method by VIN, because two cars that look alike from the outside can use different electronics. We will not guess and then find out on your driveway.
- Basic remote fob: buttons for lock, unlock, trunk, and panic, usually paired with a separate metal key that may carry its own chip.
- Flip-key or remote-head key: the blade folds into the fob. It often needs both the remote functions and the immobilizer chip registered to the car.
- Smart or proximity fob: the car unlocks as you approach and starts with the push of a button. A small emergency blade usually hides inside the case.
- Push-to-start and push-button-start keys: same idea as a smart fob, and the car must recognize the new fob before it will run.
- Spare key fob: an additional fob added to the car while you still have a working one, which is the simplest case we handle.

Call (213) 577-1366How does key fob programming work, step by step?
Programming means teaching the car's computer to recognize a new fob. The new fob is a blank until that happens, so buying the case is only half the work. This is how a typical mobile visit goes.
- You call (213) 577-1366 and tell us the year, make, model, whether the car starts with a button or a key, and how many working fobs you have left.
- We confirm the correct fob and programming method by VIN, and we tell you plainly if your vehicle is one that only a dealer can complete.
- The van comes to your car in West Covina. We check that you are the owner by matching your ID to the registration or title before we create any key.
- If the fob has an emergency blade or a flip-key blade, we cut it to fit your locks.
- We connect programming equipment to the car's diagnostic port and register the new fob. Some vehicles also require a security-access step before they accept a new key.
- If a fob was lost or stolen, we remove it from the car's memory where the vehicle allows it, so the missing fob no longer works.
- We test everything: lock, unlock, trunk, panic, remote start if equipped, the emergency blade in the door, and starting the engine. We do not leave until each function works.
What if you have lost every key to the car?
Adding a spare when you still have a working fob is one kind of job. Having no working fob at all is another, and it usually takes more equipment and more steps because the car has no existing key to learn from. That situation belongs to our lost car key replacement service, and the wider options for making a new key from scratch are covered on our car key replacement page.
If your fob is gone and the keys are still sitting inside a locked car, the first problem is getting in. That is a car lockout job, and we can usually handle the entry and the new fob in the same visit.
If you are holding an older chipped key without remote buttons, you probably need transponder key programming rather than a fob. We are glad to sort out which one applies on the phone.
What affects the cost of key fob replacement in West Covina?
We don't quote numbers in a web page because the honest answer depends on your car, and a made-up range would mislead you. What we can do is tell you exactly what moves the price so nothing about the quote surprises you. On the phone we will give you a clear figure once we know your vehicle.
- The type of fob: a basic remote is a lighter job than a smart fob with proximity entry and push-button start.
- Make, model, and year: some vehicles use more expensive hardware or more involved security steps than others.
- Whether you have a working key: adding a spare is usually the lighter-cost job, while all keys lost takes more work.
- Part source: an original-equipment fob and a quality aftermarket fob are priced differently, and we will explain the tradeoffs for your car.
- Blade cutting: fobs with an emergency or flip blade need that blade cut to your locks.
- Number of fobs: programming two at once is usually more efficient than coming back for a second one.
- Time and location: after-hours calls and mobile travel to your spot are part of the picture, and we will say so up front.

Call (213) 577-1366When is the dealer the only option?
Mobile key fob programming covers a lot of vehicles, but not all of them, and we would rather tell you that than waste your evening. Some newer or specialized models tie their fobs to factory-only tools, factory-ordered parts, or online security that independent shops cannot access. When that is the case for your car, we will say so after checking your VIN, and we will not take payment for a job we cannot finish.
Where a vehicle is on the borderline, we confirm in person before promising anything. Fob compatibility information is not always consistent from one source to the next, so we check the actual car rather than rely on a chart.
One more honest point: a fob is not always the real problem. If you have a fresh, working fob and the car still will not start or the key will not turn, the fault may be in the ignition or the car's receiver. In that case an ignition repair visit makes more sense than another fob, and we will test before you spend money on a part you do not need. Where it fits, going with us tends to be the more economical route because there is no tow and no waiting on a dealer appointment, though that depends on the vehicle.
Where do West Covina drivers need a fob replaced?
Fob problems rarely pick a convenient moment. A common version is the dead or missing fob in a parking lot. If you are stuck in a lot at Plaza West Covina or Eastland Center and the car will not recognize your smart fob, you do not need to wait for a tow. Our mobile vans come to you and program the new fob right where the car sits.
Residential areas bring their own pattern. Homes in South Hills sit on hillsides, and a fob lost on a hike or left in a hot car near the ridgelines can leave you stuck at your own driveway. In Woodside Village, the HOA-managed townhomes and condos mean many drivers share lots or garages, where getting a car moved is awkward, so fixing the fob on the spot saves a lot of hassle. The same goes for the condo and apartment complexes that cluster near the malls and the I-10 corridor. Neighborhoods like the Shadow Oak Park area, the Galster Park area, Cameron Park, Cortez Park, and the Civic Center and Plaza district all get the same visit.
We serve all of West Covina, including ZIP codes 91790, 91791, and 91792. Our storefront at 10740 Wilshire Blvd in Westwood is roughly 30 miles away, which is exactly why we run mobile locksmith vans: the programming equipment travels to your car, so you do not have to bring a car that will not start to us.

Call (213) 577-1366Why call Wilshire Lock & Key for a key fob?
We have been in business since 1987, and that history means we have seen how fob technology has changed from simple remotes to push-button smart keys. We run a real storefront in Westwood plus mobile service vans. When you call, you reach our own team, not a call center that sells your job to whoever picks it up. There are no dispatch middlemen between you and the person working on your car.
David, our owner and lead technician, oversees the work. That matters on fobs, because programming mistakes can be costly and hard to undo. We would rather slow down, check the VIN, and test everything than rush.
Our phone line is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366, so a dead fob at night or on a holiday is still worth a call. If you need us outside of regular hours, our 24-hour locksmith service runs on the same line.
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith who shows up at your car for it, including us. Anyone legitimate will be happy to answer. You should also be wary of anyone who cannot tell you what a job involves or will not explain the price before starting work.
What should you have ready when you call?
A few details speed things up and help us give you a straight answer on the first call. None of it is complicated, and if you are missing something we can usually find it together.
Most of this is just a quick look at the car and your wallet before you dial.
- Year, make, and model of the car, plus the VIN if you can read it through the windshield or find it on your registration.
- Whether the car starts with a key or a push button.
- How many working fobs or keys you still have, including any old ones in a drawer.
- Your ID and the vehicle registration or title, since we need to confirm ownership.
- Where the car is parked, so we can plan the visit.
Frequently asked questions
Can you program a key fob I already bought online?
Sometimes. Online fobs vary a lot: some are the wrong type for your car, some are locked to another vehicle, and some are low-quality copies that will not program at all. Call us with your VIN before you buy, and we can tell you what will work. If you already have one, bring it up on the call and we will check it before promising anything.
How long does key fob programming take?
Many jobs are finished in a single visit at your car, but the time depends on the vehicle, the type of fob, and whether you have a working key. Some cars need extra security steps. We will not quote a time we cannot stand behind, but we will tell you what to expect once we have your VIN.
Do you replace push-to-start and smart fobs?
Yes, for the vehicles we can support. Proximity fobs and push-button-start keys are a regular part of our work, though the exact method varies by make and year. For the few models that are dealer-only, we will say so plainly after checking your VIN.
I lost my only fob. Can you still make a new one?
In many cases, yes. It is a bigger job than adding a spare because there is no existing key to learn from, and it depends on the vehicle. We confirm by VIN whether it can be done at your car or whether the dealer is the only route.
Do I need to show ID and registration?
Yes. We need to confirm that you own the vehicle before making any key or fob for it. Have your photo ID and the registration or title ready. This protects you as much as it does us.
Is a locksmith more economical than the dealer for a fob?
Often, because there is no tow to a dealership and no waiting for an appointment, but it depends on the car and the fob. For some vehicles the dealer is the only option, and we will tell you if yours is one of them.
Will my old or lost fob still work after you program a new one?
Where the vehicle allows it, we remove the lost fob from the car's memory so it can no longer start or unlock the car. If you only want a spare added, we can keep your existing fobs working. Tell us which you want when you call.
Can you fix a worn or broken fob instead of replacing it?
Sometimes. A weak battery is the most common cause and is the easiest fix. If the case or buttons are worn but the internal electronics still work, we may be able to move them into a new shell. If the circuit board is damaged by water or impact, replacement is the realistic answer.
Do you come out to West Covina at night?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, and our mobile vans cover West Covina across ZIP codes 91790, 91791, and 91792. Call, tell us about the car, and we will give you an honest picture of what we can do.
