What kind of key fob do you actually have?
People use the word fob for several different things, and the type decides how the replacement works. Before we talk about programming or cost, it helps to sort yours into one of these groups.
A fob that is not working, or one you no longer have, is rarely a mystery once we know which group it belongs to. If you are not sure, a photo of the key and the dashboard is enough to start a conversation.
- Remote head key: a metal blade that turns in the ignition, with lock and unlock buttons built into the head. It usually has a transponder chip inside too.
- Flip key: the blade folds into the fob body. Same idea as a remote head key, different housing.
- Separate remote: a plain button remote on your key ring that handles door locks and maybe the trunk or hatch, while a different chip key starts the car.
- Proximity key, also called a smart key: you keep it in a pocket or bag, and the car senses it. This is the type used with push to start and push button start ignitions.
- Emergency-blade smart key: a smart key with a hidden metal blade inside, meant only for opening the door if the fob battery dies.
What happens when your fob stops working in Huntington Park?
Fob trouble tends to show up at bad moments: the car will not unlock in a parking lot, the push button does nothing, or the dashboard says key not detected. Sometimes the fob is simply gone, dropped somewhere or left in a jacket that went to the wrong place.
There are really only a few situations, and each one has a different fix. The first is a worn-out battery, which is the lighter-cost problem and often has nothing to do with the electronics. The second is a cracked case, worn buttons, or water damage, where the fob still has a working chip but the shell or circuit board is failing. The third is a fob that has lost its connection to the car after a battery change or a jolt. The fourth is a fob that is lost, stolen, or broken beyond use.
If you have one working fob left, you are in a much better position than someone with none. Please do not wait until the last one fails. The difference between making a spare and replacing every key after a loss is real, and we explain it further down.
If you are locked out with the fob inside the car, that is a different job, and our car lockout service covers it. If you have lost every key and the car will not start, the process is closer to what we describe on our lost car key replacement page.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366Do you need a new fob, or just a battery or a re-sync?
We would rather tell you honestly that you need a battery than sell you a fob you do not need. Many fobs use a small coin cell that you can swap yourself with the right tool. If the range has been shrinking, or the car sometimes ignores the button, the battery is the first suspect.
A new battery does not fix a cracked circuit board, a worn-out button contact, or a fob that was dropped in water. If you changed the battery and the fob still does nothing, or it works only when you press it in a certain spot, the problem is probably inside. Some remotes also need to be re-learned by the car after the battery has been out for a while, and that sometimes needs programming equipment.
Over the phone we will ask what the fob does and does not do, which tells us a lot. If the answer points to a simple fix, we will say so. If it points to a replacement, we will explain what that involves for your specific vehicle.
How we replace and program a key fob
Our technicians come to you with the equipment in the van, so you do not need to tow the car anywhere. The process is the same whether you are in a driveway, a lot, or at work, though some vehicles take longer than others.
We do not promise one method for every car. Some vehicles can be programmed on site with the key you already have, some need a longer process if no key is left, and some are dealer-only for the newest or most locked-down systems. Which category yours falls into depends on make, model, and year, and we confirm it by VIN and in person rather than guessing.
- You call (213) 577-1366 and tell us the make, model, year, and whether you have any working key.
- We ask a few questions about the fob type and what is happening, so we know what to bring.
- A technician arrives, checks the VIN and the vehicle in person, and confirms what the car needs before any work starts.
- We cut a new blade if the key has one, using your VIN or an existing key as the reference.
- We program the new fob or smart key to the car and test the lock and unlock buttons, the trunk or hatch, and the ignition or push button start.
- If you want, we program a spare at the same visit, which is easier now than after the next loss. We also remove lost fobs from the car's memory where the system allows it, so a missing key cannot be used.

Call (213) 577-1366What affects the cost of key fob replacement?
We do not quote numbers on a web page, because the honest answer depends on the car. What we can do is tell you what moves the cost up or down, so the quote you get makes sense.
Knowing these factors also helps you compare quotes fairly. Two prices for the same car can differ because one includes a key blade and a spare and the other does not.
- Fob type: a basic button remote is generally the lighter-cost job, while a proximity key for a push button start car involves a more expensive part and more programming.
- Make, model, and year: some manufacturers are straightforward, others use locked-down systems that take more time or are dealer-only.
- How many working keys you have left: adding a key when one still works is usually the more economical route compared with starting from zero keys.
- Whether the blade needs cutting: smart keys with an emergency blade and remote head keys need a cut; some fobs do not.
- Part source: we may use an original-type or aftermarket fob depending on what is available and suitable, and we will explain the difference.
- Time and location: after-hours calls and distance can affect the final figure, and we tell you how before we start.
- Extra work: a failing ignition or damaged lock can complicate programming, and in that case we point you to ignition repair before anything else.
Should you make a spare key fob now, or wait?
If you have one fob left, a spare is almost always the better path. With a working key present, programming a new one is simpler than recovering from a total loss. It is usually the more economical route, and it spares you the stress of doing it in an emergency.
Once every fob is gone, the process changes. The car may need to be reset, a new key made from the VIN, and old keys erased from memory. That is possible for many vehicles, but it takes more steps than adding a copy. For a broader overview of making additional keys, our car key replacement page covers what we do beyond fobs.
A practical tip: keep the spare somewhere other than the car, home, or the same bag as the first fob. A spare that is stolen with the original does not help much.
Key fob service across Huntington Park
Huntington Park is in ZIP 90255, about 17 miles from our Westwood storefront at 10740 Wilshire Blvd, and our mobile vans cover the city. A fob replacement here usually starts with a phone call and ends with the technician working beside your car, wherever it is parked.
Think of the Pacific Boulevard downtown district, where shop owners and employees often drive to work and park near the retail strip. A dead fob at the start of a shift is a real problem when the store needs to open. Along the Florence Avenue and Slauson Avenue corridors, people are in and out of their cars all day, and a fob that fails mid-errand needs help where the car is sitting, not a tow to somewhere else.
The apartment blocks around Salt Lake Park bring a different scene. Huntington Park is renter-majority, and with dense low-rise buildings, a lost fob can mean being locked out of the car and sometimes the home too, if the car key and apartment key share a ring. If that happens, we handle the car side with fob replacement and can also help with an apartment lockout in the same trip.
Inland basin summers are hotter than the coast, and a parked car can get very hot. Heat is hard on plastic cases and batteries, and leaving a fob on a dashboard or in a hot car can shorten its life. We are not saying heat will break your key, only that it is worth keeping the fob out of direct sun when you can.
Wherever you are in town, from the Miles Avenue area near the Civic Center to the northern edge near Vernon, call the same number and tell us where you are parked. Our mobile locksmith service is built around coming to you.

Call (213) 577-1366Why call Wilshire Lock & Key for a fob replacement?
We have been in business since 1987, and that history shows up in the details. We are one company with a storefront in Westwood and our own mobile vans. When you call, you reach us, not a call center that sells your job to whoever picks it up.
David, the owner and lead technician, oversees the work. If a vehicle is unusual, or you are not sure whether a fob is the right fix, that is where his experience matters. We would rather spend a few minutes sorting out the right answer than sell you the wrong part.
Our phones are answered 24 hours a day, 7 days a week, year-round at (213) 577-1366. We serve 140 cities across Los Angeles and Ventura counties, and Huntington Park is one of them. For wider automotive work like chip keys, ignition cylinders, and lockouts, see our automotive locksmith page, and for the chip side specifically, transponder key programming.
One more thing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you call for it. It is a fair question, and a good company will not mind being asked.
What to have ready when you call
A few details make the call shorter and the answer more accurate. None of them are hard to find, and if you are missing something, tell us and we will work around it.
Do not be worried if you do not know the fob type by name. Describe it: buttons, shape, whether there is a metal blade, and whether you start the car with a key or a button.
- Make, model, and year of the vehicle.
- Where the car is parked, including cross streets or the lot, so we can find you.
- How many working keys you have, including any spare at home.
- Whether the car is a push button start model, or uses a key in the ignition.
- What the fob does now: nothing at all, partial buttons, or a message on the dash.
- Proof you own the car, such as registration or ID. A responsible locksmith will ask for it before making a key.
Frequently asked questions
Can you replace a key fob in Huntington Park if I have lost all my keys?
In many cases, yes. We make a new key from the VIN and program it to the car on site. The process takes more steps than copying a key you still have, and some newer vehicles are dealer-only. We confirm by VIN and in person, and we tell you plainly if yours is one of the exceptions.
Do you program push button start and proximity keys?
We handle many push button start and proximity key systems, which are the keys that stay in your pocket. Whether we can do your car depends on its make, model, and year, so we check the VIN and the vehicle in person before promising anything.
Is it more economical to make a spare fob before I lose the last one?
Usually, yes. Programming a new fob while a working one is present is simpler than recovering from zero keys. It is the lighter-cost route compared with an all-keys-lost situation, and it removes the pressure of doing it when you need the car.
How much does key fob replacement cost?
We do not list numbers online because the cost depends on fob type, vehicle, how many keys are left, whether a blade must be cut, and the time of day. Call (213) 577-1366 with your make, model, and year and we will explain what applies to your car.
Can you come to me, or do I have to bring the car in?
Our mobile vans come to you in Huntington Park, wherever the car is parked. You do not need a tow for a standard fob job. We also have a storefront at 10740 Wilshire Blvd in Westwood, but most fob work here is done on site.
My fob is working only some of the time. Do I need a new one?
Not always. A weak battery is the most common cause and the lighter-cost fix. If a new battery does not help, the internal contacts or circuit board may be worn or damaged, and then replacement makes sense. Describe the symptoms when you call and we will tell you what we think.
Can I program a fob myself?
On some vehicles, owners can run a self-programming routine with the correct fob and a key already working. Many cars do not allow it, and a wrong-frequency fob from an online listing will not pair at all. If you have tried and it did not work, we can look at the car and sort out why.
Will the old, lost fob still work after you program a new one?
Where the car's system allows it, we remove lost keys from memory when we program the new ones, so a missing fob cannot be used on the car. Not every vehicle supports this, and we tell you what is possible for yours.
What should I check when hiring a locksmith for a fob?
Ask for their BSIS LCO license, which California requires of locksmith companies. Ask what the quote includes, whether it covers a spare and blade cutting, and who will come to the car. A clear answer to each is a good sign.
