What does key fob replacement in West Hills actually involve?
A key fob looks like a simple plastic case with a few buttons, but inside it is a small radio transmitter, usually a transponder or security chip, and a battery. Replacing one is not just a matter of cutting a blade. The new fob has to be matched to your vehicle's computer so the car recognizes it and, in most cases, stops recognizing a fob that has been lost. That matching step is the programming, and it is the part that separates a working key from a useless piece of plastic.
Most calls we get fall into a few plain situations: the fob was dropped, soaked or run over; the buttons wore out; the fob stopped working and a new battery did not fix it; you only have one fob and want a spare before it becomes a problem; or the fob is gone entirely. Each of those has a slightly different path, and we will tell you which one you are on after a short conversation and your vehicle's VIN.
This page covers the fob itself: remote car key replacement, smart car key replacement, spare key fob making and key fob programming. If your situation is really a lost-key emergency, a broken ignition or a locked-out car, those are separate jobs, and we point you to them below so you get the right help.
Remote fob, flip key or push-button-start smart key: which one do you have?
The name on the key does not always tell you what is inside, so it helps to sort your key into one of a few families before we talk about replacement.
We do not guess at chip types or programming methods from the badge on the trunk. Requirements vary by make, model and model year, and some vehicles change within the same year. We confirm by VIN and, when needed, by looking at the vehicle in person before we promise a path.
- Remote head key or flip key: a metal blade that turns in the ignition, with lock and unlock buttons built into the head or folded into it. The blade is cut, and the chip and remote functions are programmed.
- Separate remote plus a plain transponder key: two pieces. The remote may fail while the key still starts the car, or the other way around.
- Proximity key or smart key: you keep it in a pocket or bag, the doors sense it, and the car starts with a button. This is the push to start key replacement and push button start key replacement category.
- Emergency blade inside a smart fob: many proximity fobs hide a small mechanical key for use when the battery is dead. A fob with a blade is still a smart key, and the blade alone will not start the car.

Call (213) 577-1366How we handle a key fob replacement, step by step
We keep the process the same every time because it prevents surprises. The steps below are the order we work in, whether we are at your home in West Hills or at a parking lot.
- You call (213) 577-1366 and tell us the year, make and model, and whether you still have any working key. A person answers, at any hour.
- We ask for the VIN, which is visible at the base of the windshield on the driver's side or on the door jamb sticker. The VIN lets us confirm which fob type your car uses rather than relying on memory or a guess.
- We tell you plainly whether your vehicle can be done by a mobile locksmith or whether it falls into a case that only the dealer can handle. Some vehicles and some situations do require the dealer, and we say so up front instead of sending a van that cannot finish the job.
- Our technician arrives in a mobile van with the equipment to cut keys and program fobs on site. We check your ID and proof of ownership before making a key, which protects you as much as it protects us.
- We cut the emergency or ignition blade if your key has one, then program the new fob to the vehicle. We test every button, the door locks, and starting the car, including the proximity function on push-button-start vehicles.
- If you want, we also program a spare while we are there, and we can erase a lost fob from the car's memory where the vehicle allows it. You leave with working fobs and a clear idea of what was done.
What if I lost my only key, or I have a spare?
Having a working fob makes this simpler, and it is usually the more economical route. When the car already has a key that works, a new fob is generally added to the existing set. That is why we encourage a spare key fob before you need one: the job is more straightforward, and you are not stuck at the side of the road at night.
If every key is gone, the job changes. With no working key, the process often requires more steps and a longer visit. Our page on lost car key replacement explains how that works. If your vehicle uses a chip-based key rather than a smart fob, the details are on our transponder key programming page, and our broader car key replacement page covers the full range of keys.
If the key goes into the ignition but will not turn or the car will not start even with a good fob, the problem may be the ignition rather than the fob. We look at that honestly, and ignition repair is a separate job we handle if that turns out to be the cause.

Call (213) 577-1366What affects the cost of a key fob replacement?
We do not quote prices on a web page because the honest answer depends on your vehicle. We would rather explain what moves the number so there are no surprises when we give you a quote on the phone.
A phone quote after we have your VIN is more accurate than any range posted online, and we will tell you what is included before the work starts.
- Fob type: a basic remote head key costs less to replace than a proximity smart key with encrypted communication, and different brands cost different amounts for the same type.
- Whether you have a working key: adding a fob to an existing set is typically simpler than creating a first key from nothing.
- How many fobs you need: a spare made in the same visit is usually the lighter-cost way to get a second fob, because the technician is already set up and the vehicle is already connected.
- Vehicle requirements: some vehicles need extra security steps or access codes. Where a dealer is the only option, we tell you rather than start a job we cannot finish.
- Parts: original fobs and aftermarket fobs are different products. We explain the difference in what you get, and you choose.
- Time and location: a night call, a hard-to-reach location or a longer visit affects the final amount. We explain this before we dispatch, not after.
Why call Wilshire Lock & Key for your key fob?
We have been in business since 1987, and key technology has changed a lot in that time. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so the same company that cuts keys at the shop is the one that drives to you. There is no call center handing your job to whoever is available; you deal with one company from the first call to the finished job.
David, the owner and lead technician, oversees the work. That matters on fobs because the job is not only the programming; it is knowing when a vehicle is outside what a mobile visit can do, and saying so. We would rather tell you that something needs the dealer than take your payment and leave you with a half-finished job.
Our phones are answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. West Hills is about 23 miles from our Westwood base, and our vans are built for that kind of distance. When you call, ask where the van is coming from and we will tell you what to expect for your situation. Our automotive locksmith page gives the broader picture of what our vans carry and the vehicle work we do.

Call (213) 577-1366Key fob service around West Hills: Platt Village, Fallbrook Center and the hillside edge
West Hills is almost entirely residential, and that shapes how fob calls look here. Most households have driveways and garages rather than shared apartment parking, so the typical visit is our van at the curb or in the driveway. We work on cars where they are parked, whether that is a street off Valley Circle Boulevard, a cul-de-sac near Shadow Ranch Park or a longer driveway on a larger lot toward Castle Peak.
Some of the most common situations we hear about are in the commercial pockets. Someone does their shopping around the Fallbrook Center area or Platt Village, comes back out, and the fob is gone or has failed. In that case we come to the parking lot, confirm the vehicle by VIN and program a replacement there. Our mobile locksmith page explains how mobile work operates, and if you are locked out with the fob inside, our car lockout service is the first call.
Work near the UCLA West Valley Medical Center campus often involves people who park for long shifts and come out to a dead or missing fob. Families around Knapp Ranch Park and the Orcutt Ranch area are more likely to need a second fob for a teenage driver or a shared family car. We handle both, in the 91307 and 91304 ZIP codes and beyond.
If you live near El Escorpion Park on the hillside, the household often has several vehicles and a longer driveway. That is a good time to make spares for every car rather than waiting for the next failure. And since West Hills summers run hot in this far-west corner of the Valley, we suggest keeping a spare fob inside the house rather than in a parked car, where it can be lost or stolen along with the vehicle.
Before you call: a quick checklist
A few checks can save you a service call, and a few pieces of information will make the call faster. None of this is complicated, and if you are unsure we will walk you through it on the phone.
- Try a fresh battery first if the fob still has some life. A weak battery causes a short range or intermittent response; a battery swap is cheap and quick, and we will tell you honestly if that is all you need.
- Look for a hidden blade in the fob. If the car will not unlock by remote, the emergency blade can open the driver's door, but it will not start a push-button-start car.
- Have the VIN and your ID ready. Registration or insurance documents showing you own the vehicle are typically what we ask for.
- Note what still works. If the buttons work but the car will not start, that is useful information, because it points to the chip or ignition rather than the remote.
- Do not keep pressing the buttons or trying different batteries in sequence. If the fob was wet or damaged, repeated attempts do not help.

Call (213) 577-1366What should you ask any locksmith before you hire them?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for it before they start work, and ask for the business name and physical address too. A company that will not answer is a reason to hang up.
Also ask whether the person coming to you works for the company you called. Some listings route calls to dispatch services that send whoever is available. With us, the company answering the phone is the company doing the work.
Frequently asked questions
Can you program a key fob at my home in West Hills?
In most cases, yes. Our mobile vans carry the equipment to cut keys and program fobs on site, so we can work at your home, workplace or parking lot. Some vehicles have requirements that only a dealer can meet, and we will tell you that on the call once we have your VIN, before anyone drives out.
How do I know if my car uses a remote fob or a smart key?
If you carry the key in a pocket and the car starts with a button, it is almost certainly a proximity smart key. If you put a metal blade in the ignition and turn it, it is a remote head key or a transponder key. We confirm by VIN rather than guessing, because the same model can use different keys in different years.
Can you make a spare key fob if I still have one that works?
Yes, and this is the best time to do it. When a working fob is available, adding a second one is generally more straightforward than starting from nothing. Making the spare before the original fails is usually the more economical route, and it saves you from a lost-key emergency later.
Does a replacement fob from the internet work?
Sometimes, but it depends on the fob and on the vehicle. Online fobs are often the wrong frequency or chip type, or have been locked to another vehicle and cannot be reused. If you bring one, we will check it before charging for programming and tell you honestly whether it will work with your vehicle.
Will you disable my old fob if it was lost or stolen?
Where the vehicle allows it, we can erase lost fobs from the car's memory during programming so only the ones you hold will work. Not every vehicle handles this the same way, so we confirm how yours behaves when we look it up by VIN or at the vehicle.
What do you need from me to make a new fob?
We ask for the VIN and proof that you own or are authorized to use the vehicle, along with your ID. This is standard practice for responsible locksmiths, and it protects you against someone else getting a working key to your car.
Is it cheaper to go to the dealer for a key fob?
It depends on your vehicle. For many cars a mobile locksmith is the more economical route and avoids a tow or a trip, while for some vehicles only the dealer can do the job. We tell you which case applies when we have your VIN, and we explain what affects the quote before work starts.
Can you replace the case or buttons on my fob instead of the whole fob?
Sometimes. If the electronics inside work and only the shell or the buttons are worn, a repair or shell swap can be the lighter-cost option. If the board or chip is damaged, or the water got in, replacement is usually the better answer. We look at it and tell you which one makes sense.
What if my fob stopped working in the middle of the night?
Call (213) 577-1366. Our phones are answered 24 hours a day, 7 days a week. If you are stranded, we will tell you what we can do on site and what needs to wait, and if the issue is that you are locked out, our car lockout service is a separate call we handle in the same way.
