What counts as a key fob, and what does replacing one involve?
People use the word fob for a few different things, and the difference matters because it changes how the job is done. A basic remote is a separate button unit that locks and unlocks the doors, often paired with a metal key that starts the car. A flip key folds a blade into a remote body. A proximity fob, sometimes called a smart key, lets you open the door and start the engine without taking it out of your pocket. If your car has a push-to-start or push-button start ignition, you have one of those.
Replacing a fob is not the same as cutting a copy of a house key. The new unit has to be the right hardware for your vehicle, and then it has to be introduced to the car so the car accepts it. That second step is programming. A fob that looks identical to yours can still be the wrong part, which is why we ask for the year, make, and model first and confirm by VIN before we commit to anything.
This page covers remote and smart fob replacement and programming. If you have lost every key to the car, our lost car key replacement page covers that situation in more detail. If you need a standard transponder key rather than a fob, see transponder key programming.
What happens when a fob dies, breaks, or goes missing in El Monte?
The situations we hear about are fairly ordinary. The buttons stop responding. The case cracks and the circuit board falls out. The car shows a key-not-detected message and will not start. The fob goes through the wash in a pocket. Or it simply disappears between the grocery store and home, and now you have one fob left or none.
A dead battery is the lighter-cost cause, so it is always worth ruling out first. If the fob has stopped working, replacing its battery sometimes brings it back. If the fob has been dropped, soaked, or has stopped communicating with the car entirely, the unit usually needs to be replaced and reprogrammed.
The worst timing is when you are down to your last fob. Once it fails, you are no longer making a convenient spare. You are dealing with a stranded car. If you still have one working fob, a spare is much easier to arrange than a replacement after everything is gone, and it is worth doing before you are in a hurry.
How do we replace and program a key fob?
We work from the vehicle, not from guesswork. Here is how a typical call goes, and where it can differ depending on the car.
- You call (213) 577-1366 any time, day or night, and tell us the year, make, and model, and whether the car has a push-to-start button or a turn-key ignition.
- We ask what you still have. A working fob, a broken fob, or no fob at all each lead to different next steps.
- We confirm the correct fob for your car using the VIN. Some vehicles have several fob styles across the same model year, so we do not rely on appearance alone.
- We come to your location with the mobile van, or you can come to our storefront at 10740 Wilshire Blvd in Westwood if that suits you better.
- We verify you are the owner or have authority over the vehicle. Expect to be asked for ID and proof of ownership, such as registration. We will not program a fob for someone who cannot show a connection to the car.
- We program the new fob so the car recognizes it, then test every function: lock, unlock, trunk or liftgate where applicable, panic, and starting the engine.
- If you have other fobs, we check that they still work after programming. Depending on the vehicle, programming a new fob can require the car to be told about every fob it should accept, and we confirm what your car needs at the VIN stage rather than assuming.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366Can a locksmith program every fob, or are some dealer-only?
Honestly, not every vehicle is the same, and we will tell you plainly when a car falls on the harder side. Some makes and models can be handled by a locksmith with the right equipment. Others have security setups that restrict programming to the dealer, particularly in certain situations such as when all keys have been lost. Information on this changes by model year and sometimes by individual vehicle, so we do not give a blanket answer over the phone.
What we do instead is confirm by VIN and, when needed, in person. If your car can be handled by us, we will say so and go ahead. If it turns out to be dealer-only, we will say that too, and not collect a deposit on something we cannot finish. A dealership, such as the one on the El Monte side of town at Longo Toyota, is the right place to go in those cases. You lose nothing by calling us first to find out which category your car is in.
If your fob problem is a symptom of something else, such as a car that will not start even with a good fob, the cause may be the ignition or the immobilizer system. That is a different repair, and our ignition repair page explains it.
What affects the cost of key fob replacement?
We do not quote prices on a web page, and we would be wary of any company that does without knowing your car. Fob jobs vary too much. These are the factors that actually move the cost:
- The vehicle itself. Make, model, and year decide which fob hardware is needed and how involved the programming is.
- The type of fob. A simple remote is generally a lighter-cost job than a proximity smart key for a push-button start car.
- How many keys you still have. Adding a spare to a car with a working fob is usually more economical than starting from nothing.
- Whether a key blade needs cutting. Many fobs include an emergency blade that has to be cut to match.
- Where the work happens. A mobile visit to your driveway or parking lot involves travel, while a visit to our Westwood storefront does not.
- Time of day. Calls in the middle of the night or on a holiday are handled differently from daytime appointments.
- Whether the car is dealer-only. If so, our part is to tell you and save you the wasted trip, and you pay the dealer for the actual work.

Call (213) 577-1366Should you call a locksmith or go to the dealer for a replacement fob?
There is no single right answer, and anyone who tells you there is has something to sell. A dealer is a legitimate choice, especially for vehicles that are restricted to dealer programming. Their parts are factory parts, and for some cars it is the only route.
Where a locksmith helps is convenience. We come to the car, so you do not have to arrange a tow just to get a key made, which matters when the car will not start. We also work outside regular business hours, and our phone is staffed around the clock. For many vehicles, going through a locksmith is the more economical route, though that depends on the car and we would not claim it for every one.
Whoever you choose, ask about licensing. California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask any locksmith for that number before work begins. It is a fair question and a good company will not mind answering it.
Why call Wilshire Lock & Key for a fob?
We have been in business since 1987. That is a long time to be answering the phone for people locked out, stranded, or short a key, and it has taught us to be straightforward about what we can and cannot do.
We are one company. When you call (213) 577-1366, you are reaching us, not a national call center that hands the job off to whichever subcontractor is closest. We have a storefront at 10740 Wilshire Blvd in Los Angeles, CA 90024, and mobile service vans, so you can drive to us or have us come to you.
David, the owner and lead technician, oversees the work. If a vehicle is unusual or a job does not look like it fits the normal pattern, that is the kind of call he is involved in.
Our broader vehicle work is described on the automotive locksmith page, and the general key options are covered under car key replacement. This page stays focused on fobs.
Key fob help across El Monte: Five Points, Norwood Village, the Flair Park area, and more
We serve El Monte in Los Angeles County, in ZIP codes 91731 and 91732, and the city is about 25 miles from our Westwood base. That is why we run mobile vans for this kind of call. We bring the programming equipment to the car instead of asking you to bring a car that may not start to us.
Think about how El Monte actually lives. A lot of the housing here is postwar bungalows and small ranch homes, along with small apartment complexes and backyard units, in neighborhoods such as Five Points, Norwood Village, and Arden Village. Many of these homes rely on street parking or a shared lot, so a dead fob often means a car that will not start right where it sits. We can program a fob at the curb or in the lot, as long as we can reach the vehicle and you can show you own it.
Commuters raise a different case. If you leave a car near the El Monte Station transit center and come back to a fob that no longer works, you may be dealing with a dead battery or a failed fob in a place where it is awkward to wait. If you are in the Flair Park business district or the Northwest Industrial District, work vehicles with smart fobs create the same problem at a bigger scale, and a missing fob can idle a driver for the day. We can come to the lot instead of making you move the vehicle.
Summers in El Monte are hot and dry, and there is little coastal relief, which is one more reason not to wait around in a parking lot for help. If you also have a car lockout with the fob inside the vehicle, our car lockout service handles getting you in, and we can then deal with the fob.

We answer around the clock, every day of the year.
Call (213) 577-1366What should you have ready before we arrive?
A few things speed up the visit and keep it from stalling at the verification step. None of this is complicated.
- Your vehicle's year, make, and model, and the VIN if you can read it from the dashboard or the door jamb.
- Photo ID that matches the vehicle registration or ownership paperwork.
- Any key or fob you still have, even if it is cracked or only half works. It can help us identify the correct replacement.
- The exact location of the car and whether it is on a street, in a lot, or in a garage, so the van can reach it.
- Whether the car has a push-to-start button, since that tells us right away whether we are dealing with a proximity fob.
How to avoid being stranded by a fob next time
The simplest protection is a spare. Having a second fob programmed before the first one fails costs less effort and less stress than replacing after a loss. If you have only one fob for a vehicle you rely on, make a spare key fob a priority.
Do not ignore early warning signs. A fob that needs several presses, a shorter working range, or a dashboard message about the key battery is telling you something. Changing the battery early is usually the lighter-cost fix.
Keep the fob away from water and avoid leaving it in a place where it can get crushed or dropped. And if you ever wonder whether your car can be handled by us or only by a dealer, just ask. You can call (213) 577-1366 at any hour, and we will tell you straight, even if the answer is that you need a dealer. If you want help from any hour of the day, see our 24-hour locksmith page, and for work that comes to you, read about mobile locksmith service in El Monte.
Frequently asked questions
Can you replace a key fob if I have lost all my keys?
Sometimes, yes, but it depends on the vehicle. Some cars can be handled by a locksmith even with no key at all, and others are limited to the dealer in that situation. We confirm by VIN, and in person if needed, before taking on the job. If your car is dealer-only, we will tell you instead of starting work we cannot finish.
Do you come to me in El Monte, or do I have to bring the car?
We come to you. Our mobile vans serve El Monte, including ZIP codes 91731 and 91732, so you do not need to tow the car or move it. You are also welcome to visit our storefront at 10740 Wilshire Blvd in Westwood if that suits you.
Can you program a key fob for a push-to-start car?
In many cases we can, but it depends on the make, model, and year. Push-button start cars use proximity fobs that need to be matched to the vehicle. Give us the VIN and we will tell you whether we can handle it or whether it needs to go through the dealer.
Is it better to make a spare fob before I lose the last one?
Yes. Adding a spare while you still have a working fob is generally easier and more economical than replacing a fob after losing everything. It also means you are never stuck with an immobile car at the worst moment.
How much does key fob replacement cost?
We do not give a price without knowing the car. The cost depends on the vehicle, the fob type, how many keys you still have, whether a blade has to be cut, and where and when the work happens. Call (213) 577-1366 with your year, make, and model and we will explain what applies to your situation.
What proof of ownership will you ask for?
We ask for photo ID and proof that the vehicle is yours or that you have authority over it, such as registration. It is a normal and necessary step. We will not program a fob for a car if we cannot verify the connection.
My fob stopped working. Do I need a whole new one?
Not always. A dead battery is the lighter-cost cause and worth trying first. If the fob has been damaged by water or impact, or it still fails after a new battery, it likely needs to be replaced and reprogrammed.
Will my old fob still work after you program a new one?
It depends on the vehicle. We check your existing fobs during the visit and confirm they work before we leave. We also tell you in advance, based on the VIN, whether the car needs all fobs to be programmed together.
Should I call a locksmith or the dealer?
Either can be right. A dealer is the correct choice for vehicles that are restricted to dealer programming. A locksmith is often more convenient because we come to the car and answer the phone at all hours. Whichever you choose, ask for the company's BSIS LCO license number, which California requires of locksmith companies.
