Do you need a new key fob, or just a battery?
Start with the simple possibility. A fob that only works when you hold it against the door, or a dashboard message about a low key battery, usually points to a worn coin cell rather than a dead fob. A battery swap is a quick job you can often do yourself with a small flat screwdriver and the cell number printed inside the case. If the car still ignores the fob afterward, the trouble is more likely the fob's circuit board, its programming, or the car's receiver, and that is where we come in.
Replacement makes sense when the fob is lost or stolen, the case has cracked and the board inside is damaged, it went through the wash, it got crushed in a driveway, or the buttons have worn until they no longer register. It also makes sense when you only have one fob. With a working fob in hand, adding a spare is generally more straightforward than starting over after every key is gone, so a spare key fob is worth sorting out while the original still works.
Here are the signs we hear about most often when people call about key fob replacement:
- You have to press the buttons several times, or stand right next to the car, before it responds
- The dash says the key is not detected even though the battery is fresh
- The push-to-start button does nothing unless you hold the fob directly against it
- The case is cracked, the button rubber has peeled, or the fob has been soaked
- You own one fob and nobody has a spare
- The fob is lost, stolen, or somewhere you can't get back to
What kinds of key fobs can be replaced and programmed?
Not all fobs are alike, and the type decides how the replacement is done. These are the main kinds we work with:
- Remote head keys: a metal blade and the remote buttons in one piece. The blade works the ignition or door, and the buttons lock and unlock.
- Flip keys: the same idea, but the blade folds into the fob body.
- Remote-only fobs: a separate piece used alongside a keyed ignition, or on vehicles where the key and remote were never combined.
- Smart or proximity fobs: they stay in a pocket or bag, the car senses them nearby, and you start the engine with a button. This is the proximity key replacement and push button start key replacement side of the work.
How is smart car key replacement different from copying a key?
A smart fob is not a key you can copy on a grinder. It carries its own electronic identity, and the car has to be told to accept it. That is electronic work, and what is possible depends on the make, model, and year. We do not guess your category from the badge on the trunk; we confirm it by VIN and, when needed, in person at the vehicle.
A key that has a chip in the head but no buttons is a related job with its own page, transponder key programming. If you are not sure which of the two you have, describe it to us on the phone, or send us the VIN, and we will sort it out before anyone drives to you.

Call (213) 577-1366How does mobile key fob programming work?
Most key fob jobs are done where the car is parked. Our vans carry the programming equipment, so the car does not need to be towed or driven anywhere. Here is how a typical call goes:
- Call (213) 577-1366 and give us the make, model, and year, plus whether you have any working key or fob at all.
- We confirm the exact vehicle by VIN, and we ask you to show ID and proof the car is yours. We do this for every vehicle, because programming a key to a car we cannot tie to its owner is how thefts happen.
- We tell you plainly whether the job is one we can complete on site, or whether your vehicle is a dealer-only case. We would rather say so before a van rolls than after.
- We prepare the fob, and cut a new emergency blade if the style requires one.
- We program the fob to the car. If you want a lost fob removed from the car's memory so it can no longer start the vehicle, we discuss whether your model allows that.
- We test everything: lock, unlock, trunk or hatch if equipped, panic, remote start if the car has it, and starting the engine. Then we test the spare too.
What if you have lost every key fob?
It is more stressful than having a spare, but it is a common situation and it is solvable on most vehicles. With no working fob, there is nothing for the car to learn from, so the process involves creating a new key identity for the car from scratch. That takes more steps and more equipment than adding a spare, which is why the two jobs are priced differently. We cover the full process on our lost car key replacement page, and the wider picture of car key replacement in general.
If the only fob you own is locked inside the car, you may not need a new one at all. That is a car lockout situation, and getting you in without damage is a different, usually lighter job than programming a new fob. Tell us which situation you are in when you call, and we will send the right equipment.
What affects the cost of key fob replacement?
We do not quote a figure without knowing the vehicle, and we will not post one here that would be wrong for your car. These are the factors that actually move the cost of key fob replacement up or down:
- The type of fob. A basic remote costs less to source and program than an encrypted smart fob for a push-to-start vehicle.
- Make, model, and year. Some manufacturers make programming straightforward, while others add layers that take more time and equipment.
- Whether you have a working key. Adding a spare to a car that still has a fob is usually lighter than recovering from all keys lost.
- Original-manufacturer fob versus a quality aftermarket one. Where an aftermarket remote works reliably on your car, it is usually the more economical route. Where it does not, we say so instead of selling you something that will fail.
- The emergency blade. If the new fob needs a cut blade, that adds a step.
- How many fobs you want. Programming a second one while we are already at the car is generally more efficient than coming back later.
- Where and when. A mobile visit to your location involves travel and, outside normal hours, night or weekend work.
- Related faults. If the real problem is a worn or damaged ignition rather than the fob, that is a separate repair, and our ignition repair page explains what that involves.

Call (213) 577-1366When does a key fob job have to go to the dealer?
Honesty matters here because it saves you time. Some vehicles, particularly certain newer models and certain brands, restrict key programming to the manufacturer. They may require factory codes, manufacturer server access, or equipment that independent shops cannot get. We do not claim we can do everything. Where the information we have on a particular vehicle is unclear or conflicting, we say that and confirm it by VIN or in person instead of promising a result.
If your car turns out to be dealer-only for a fob, we will tell you before we start. Often there is still something we can help with, such as the emergency blade, a lockout, or getting the vehicle to the dealer without a tow.
One more caution: fobs bought from online marketplaces are a gamble. Many are used units already locked to another vehicle, and some cannot be reprogrammed. If you already have one, bring it to us or send us a photo and the part numbers, and we will tell you whether it is usable before you spend more on it.
Why call Wilshire Lock & Key for a key fob?
We have been in business since 1987. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so there is a real place behind the phone number. When you call (213) 577-1366, you are reaching one company, not a call center that hands your job to whoever happens to be free. The person who shows up works for us.
David, the owner and lead technician, oversees the work. That matters on key programming, where a rushed job can leave you with a fob that works for a week and then drops out. Searches like car key fob replacement near me often return national dispatch services that sell the job and subcontract it. Ask who will actually arrive. With us, the answer is straightforward.
Our broader automotive locksmith service covers the related jobs, from keys that will not turn to ignition trouble, so you do not have to start over with another company if the problem turns out to be bigger than the fob.
Key fob replacement in Bell Gardens: what it looks like here
Bell Gardens sits in ZIP 90201, about 21 miles from our Westwood storefront, and our mobile locksmith vans come to you. Whether you are parked off the Eastern Avenue corridor, along Florence Avenue, or in the blocks off Garfield Avenue, the job happens at the vehicle.
The city is dense, mostly small pre-1960 homes and low-rise apartment complexes, with a strong renter majority. That shapes the key fob picture. In multi-unit blocks, such as the apartment complexes near Bell Gardens High School, cars are often parked in shared lots or on the street, and one fob may be passed between several drivers in a household. That is how a single fob gets lost, and why a spare is worth having before you need it. If you are in that spot and locked out of the car with the fob inside, call us before you try forcing anything.
Summer is the other local factor. The inland southeast LA County basin runs several degrees warmer than the coast, with hot, dry summers. Heat is rough on coin batteries and plastic cases of fobs left on a dashboard or in a cupholder, so fobs here tend to wear out from heat and daily handling rather than from salt air; coastal corrosion is not a factor in Bell Gardens. If your fob is acting up in July, try a new battery first.
Around the Bicycle Casino district on Eastern Avenue, a fob that goes missing after a long day is a realistic scenario, since people park and leave their vehicles for hours. The same goes for work vehicles used by businesses along that corridor. Call (213) 577-1366 and we can plan the visit to wherever the car is parked.

Call (213) 577-1366How do you check a locksmith before they work on your car?
California requires locksmith companies to hold a BSIS LCO license, and you can ask any locksmith for it before work starts. We encourage you to do the same with us or anyone else. A few other checks are worth making:
- Ask for the company name and who is coming, not just a first name on the phone
- Ask whether they will confirm the vehicle by VIN and ask for ID and proof of ownership. A technician who skips this is a red flag.
- Ask how the quote is built and what could change it on arrival
- Be wary of any quote that sounds unusually low on the phone and then grows at the car
Frequently asked questions
How much does key fob replacement cost in Bell Gardens?
It depends on the vehicle, so we do not give a blanket number. The main factors are the type of fob, the make and year, whether you still have a working key, whether an original or aftermarket fob is used, and whether a blade must be cut. Call (213) 577-1366 with your vehicle details and we will explain how your quote is built.
Can you program a key fob I bought online?
Sometimes. Many fobs sold online are used units already locked to another car, and some cannot be reprogrammed at all. Bring it to us or send us the part numbers and a photo, and we will tell you whether it is usable for your vehicle before you spend anything more on it.
Do you handle push to start key replacement?
Yes, for the vehicles where it can be done outside the dealer. Push button start and proximity systems vary by make and year, and a few are dealer-only. We confirm by VIN and tell you plainly which case yours is before we begin.
Can you come to me for mobile key fob programming?
Yes. Our vans carry the equipment, so you do not need to tow the car. We serve Bell Gardens, ZIP 90201 and the surrounding area, and answer calls 24 hours a day, 7 days a week at (213) 577-1366.
I lost my only key fob. Can you still make a new one?
On most vehicles, yes, though it is a bigger job than adding a spare. We confirm the vehicle by VIN and your ownership, then create a new key identity for the car. Some models are dealer-only for this, and we will say so honestly.
Will my old lost fob still work after you program a new one?
On many vehicles we can remove a lost fob from the car's memory so it no longer starts the car, but it depends on the model. Ask us when you call and we will tell you what is possible on yours.
What do I need to show you before you program a fob?
We will need to identify the vehicle by VIN and confirm you are the owner, so have your ID and registration or other proof of ownership ready. We ask this of everyone, because programming a key for the wrong person is how car theft happens.
Should I go to the dealer or call a locksmith for a key fob?
Often a locksmith is the more convenient route because we come to the vehicle and avoid a tow. Cost depends on the vehicle, so compare actual quotes. If your car is a dealer-only case, we will tell you straight away and not start work that cannot be finished.
Is it worth getting a spare key fob made now?
Yes, if you only have one. Adding a spare while the original still works is generally more straightforward than recovering after all keys are lost. In a household where one fob is shared between drivers, a spare can save you a stressful day.
