What does key fob replacement involve, and when do you need it?
A key fob is the electronic part of your car key: the buttons that lock and unlock the doors, pop the trunk, or, on a push-button start car, the device that tells the vehicle you are allowed to drive it. Replacing one means more than handing you a plastic shell. We source a fob that is correct for your specific vehicle, cut the emergency blade if your fob has one, and program the fob so the car recognizes it. A fob that has not been programmed is just a paperweight.
Torrance customers usually call us for a handful of reasons. The fob went through the wash. It was dropped on concrete and the case split. The rubber buttons wore through after years in a pocket. It disappeared somewhere between a parking space and the front door. Or the car came with one fob, and you finally decided that one is not enough. That last case is the easiest and the most economical time to act, because a spare made while you still hold a working key is a simpler job than one made after every key is gone.
If you are reading this from a parking lot with a car that will not respond, call (213) 577-1366. The line is answered around the clock, every day of the year, and you will talk to the company that sends the van, not a call center that resells the job.
Does your fob need replacing, or just a new battery?
Before anyone spends money on a new fob, it is worth ruling out the battery. We would rather tell you that over the phone than sell you a part you do not need. A weak coin battery causes a lot of fob complaints that look like total failure.
Here is how to tell the difference between a tired battery and a fob that is truly finished.
- Reduced range is the classic battery symptom. If you have to stand next to the car for the buttons to work, try a fresh battery first.
- Some cars show a warning message such as key battery low. That is a battery problem, not a programming problem.
- If the buttons work intermittently and the problem comes and goes, the battery or a dirty contact is the more likely cause.
- If the fob has visible cracks, a rattling sound inside, water damage, or buttons that no longer click, the circuit board may be damaged and replacement makes sense.
- If a fresh battery changes nothing and the car still does not respond to the fob at all, the fob may have lost its pairing with the car, or the fob electronics may have failed. That is when we bring a programmer and a replacement.

Call (213) 577-1366Which type of key fob do you have?
Fobs come in several forms, and the type matters because it changes the work involved. When you call, tell us the make, model, and year, and describe what your current key looks like. If you can, send us the VIN. We use it to confirm what the vehicle actually takes rather than guessing.
- Remote key with a blade: a traditional-looking key with lock, unlock, and panic buttons built into the head. It starts the car by turning in the ignition.
- Flip key: the blade folds into the fob body. These have a hinge and a small spring that wear out, and the hinge failing is a common reason people replace them.
- Proximity or smart key: you keep it in a pocket or bag, and the car unlocks when you touch the handle. This is the kind of fob that people search for as proximity key replacement or smart car key replacement.
- Push-button start fob: works with a start button instead of an ignition cylinder. Many of these also carry a hidden emergency blade that slides out of the fob for use on the door if the battery dies.
- Separate remote: some vehicles use a remote for the doors and a separate transponder key for starting. The two are programmed differently, and we will tell you which one you actually need.
How do we replace and program a key fob?
Every vehicle is a little different, but the process follows the same order. We would rather you know what is going to happen than wonder what the technician is doing in your driveway.
- You call (213) 577-1366 and give us the make, model, year, and, if possible, the VIN. We tell you plainly whether this is a job we can complete on site or whether your car is one that needs the dealer.
- We confirm the fob type and whether you have any working keys. Having one working key often changes the method, and having none changes it more.
- We ask for proof that the car is yours, such as ID and registration or title, before we make or program a key. This protects you as much as anyone.
- A technician brings the correct fob, a key-cutting setup if your fob has a blade, and programming equipment to your location in Torrance in one of our mobile vans.
- We cut or match the emergency blade if there is one, then program the new fob to the car and, where the vehicle allows, to its immobilizer system.
- We test every function: lock, unlock, trunk or hatch, panic, remote start if the car has it, and starting the engine. On push-button cars we test the proximity unlock and the start button too.
- If you had an older fob that is lost, we talk about whether it can be removed from the car's memory on your vehicle, so a lost fob cannot be used later. Some vehicles allow this and some do not, and we tell you which applies to yours.

Call (213) 577-1366What affects the cost of key fob replacement in Torrance?
We do not publish a flat figure for key fobs because the honest range is wide, and a number on a web page would be wrong for most cars. What we can do is explain what moves the quote, so the number we give you on the phone makes sense.
Once you give us the vehicle details, we can quote you before anyone drives out. Knowing the cost factors below helps you compare our quote with a dealer or another locksmith on equal terms.
- The vehicle itself. Make, model, and year decide what fob the car accepts and how hard it is to program. A basic remote head key and a proximity fob for a newer car are very different parts.
- The fob type. A simple remote costs less to source than a smart fob with a hidden blade, a touch sensor, and encrypted communication.
- Whether you have a working key. Making a spare from an existing key is generally the lighter-cost job. When every key is gone, the work is bigger, and it overlaps with lost-key service.
- Whether the blade needs cutting. A fob with an emergency blade needs cutting, and some blades use laser-cut patterns that take more specialized equipment.
- OEM versus aftermarket fobs. Aftermarket fobs are usually the more economical route, but not every vehicle accepts them. On some cars the factory part is the only reliable option, and we tell you if that is the case for yours.
- Time of day and distance. Late-night and holiday calls take a technician out of normal hours, and the drive to your location is part of the job. Torrance is roughly 21 miles from our Westwood storefront, and that is built into how we plan the trip.
- Anything else wrong. If the problem turns out to be the ignition or a failing receiver rather than the fob, the quote changes, and we tell you before we do anything extra.
When is a locksmith the right call, and when is the dealer?
For many vehicles, a locksmith can do the entire job at your location, often without a tow and without an appointment. That is the main reason people pick mobile key fob programming over the dealership. But we do not claim to cover every vehicle, and we will not pretend otherwise.
Some makes and model years lock programming behind dealer-only tools or manufacturer security access. If your car is one of those, we say so on the first call, before you have spent anything, and we point you to the dealer. We confirm the specifics by VIN or in person instead of guessing, because the answer can differ between two cars of the same model and different years.
If you have lost every key, the job moves into a different category. We handle it, and the full process is described on our lost car key replacement page. If your car uses a chip key rather than a fob, our transponder key programming service is the closer match. And for a broader look at what we offer for vehicle keys, see car key replacement in Torrance.

Call (213) 577-1366Key fob replacement across Torrance: where we get these calls
Torrance is a spread-out city, and its five ZIP codes, 90501 through 90505, cover a lot of different parking situations. We come to all of them in our mobile vans, so you do not need to get the car to a shop, which matters when the reason you are calling is that the car will not start.
In North Torrance and along Western Avenue, apartment complexes are common. That brings a particular kind of fob problem: assigned spaces, shared garages, and a fob that was last seen somewhere in the building. If you are also locked out of your unit, our apartment lockout service covers that side, and we can often sort out the car at the same visit. In West Torrance and South Torrance, the postwar ranch-style tracts mean most cars live in a driveway or an attached garage, which makes on-site programming simple, with plenty of room to work next to the car.
Old Torrance has its own character, with early-20th-century bungalows and craftsman homes, and older streets where cars are often parked at the curb. We work at the curb as easily as in a driveway. Near the coast, in places like the Hollywood Riviera side of Torrance and around Torrance Beach, the marine layer brings damp air and some salt-air wear. That is hard on small electronics and metal contacts over time, so a fob that lives in a beach bag or a damp jacket can fail sooner than one kept in a dry spot. Inland, the air is milder and drier, but summer heat is still tough on batteries and plastic cases left on a dashboard.
Shopping and work areas matter too. People lose fobs and run into dead batteries in big retail lots like the one around Del Amo Fashion Center, and in hospital and office parking near Torrance Memorial Medical Center, where the car sits for hours. We can meet you in a lot like that and complete the work beside your car. For a locked car with the fob inside, see our car lockout page, which is a separate service.
Why call Wilshire Lock & Key for your fob?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, Torrance among them. We run a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. When you call, you reach us, not a dispatch company that sells your job to whoever picks it up. The technician who arrives works for the company that answered the phone.
David, the owner and lead technician, oversees the work. Key fob programming is exactly the type of job where care matters: a wrong step can leave a car refusing to start, and we would rather slow down than rush a vehicle's security system.
One thing worth doing with any locksmith: California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask for that license number before anyone works on your car. Ask every company you consider to show you theirs before work starts. A car's key system is not the place to take someone's word for it.
Our line, (213) 577-1366, is answered 24 hours a day, every day. If you want broader context on what we do for vehicles, our automotive locksmith page lists the full range, and our mobile locksmith page explains how the van service works.

Call (213) 577-1366How do you keep a new fob from becoming another problem?
A new fob is a fresh start, and a few habits keep it that way. None of this is complicated, but most fob failures we see trace back to one of these things.
- Get a spare made now. A second programmed fob stored at home turns the next loss into an inconvenience instead of an emergency.
- Replace the coin battery before it dies. If range starts shrinking or the dash shows a warning, change it that week.
- Keep the fob away from water, heat, and strong impacts. A dashboard in summer sun and a wet pocket are both bad places.
- Do not hang a heavy bundle of keys from a fob or an ignition. The weight wears on a cylinder over time.
- Know where the emergency blade is and how to use it. Many smart fobs hide one, and it is the way in when the battery is dead.
- If a brand-new fob works the doors but the car will not start, tell us. It may point to an ignition or receiver issue, which we handle under ignition repair.
Frequently asked questions
Can you make a new key fob if I have lost the only one?
In many cases, yes. It is a bigger job than copying from a working key, because we have to work with the car directly instead of cloning an existing fob. Some vehicles can be handled on site and some need the dealer. Call (213) 577-1366 with the make, model, year, and VIN, and we will tell you which applies.
Do you come to me in Torrance, or do I have to bring the car?
We come to you. Our mobile vans travel to homes, apartment lots, workplaces, and parking structures across Torrance, so you do not have to drive a car that will not start. Our storefront is at 10740 Wilshire Blvd in Westwood, but the work is usually done where the car is parked.
Is a locksmith more economical than the dealer for a key fob?
Often it is the more economical route, especially because you avoid towing and an appointment, but it is not true for every vehicle. The cost depends on the car, the fob type, and whether you have a working key. We give you a quote before work starts so you can compare it with a dealer quote.
Can you program a key fob I bought online?
Sometimes. It depends on whether the fob is the correct type and frequency for your car, and on whether it has already been locked to another vehicle. Some online fobs cannot be programmed at all. Tell us what you have before you order, and we can tell you whether it is likely to work.
What is the difference between a remote, a transponder key, and a smart key?
A remote operates the locks from a distance. A transponder key has a chip that lets the engine start. A smart or proximity key works without being taken out of your pocket, and usually pairs with a push-button start. Some cars combine these in one fob, and we confirm which your car uses by VIN.
Will my old fob still work after you program a new one?
That depends on the vehicle. On some cars we can erase lost or unwanted fobs from the car's memory so they no longer work, and on others the process adds a fob without removing the old ones. We tell you which applies to your car before we start.
Do I need to prove the car is mine?
Yes. Before we make or program a key, we ask for ID and proof of ownership or authorization, such as registration or title. It is a routine step, and it keeps someone else from getting a working key to your vehicle.
My push-button start car says it cannot detect the key. Is the fob broken?
Not necessarily. A weak battery is the most common cause, and many cars let you hold the fob against the start button or a marked spot to start anyway. If a fresh battery does not help, the fob or the car's receiver may be at fault. We can test it and tell you which.
Can you help at night or on a holiday?
Yes. Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. Late-night and holiday calls can affect the quote because they take a technician out of normal hours, and we explain that on the phone before you agree to anything.
