What counts as a key fob, and what can we replace?
People use the words key fob for several different things, and the difference matters because it changes the job. Some cars use a metal key with the lock and unlock buttons built into the head. Others use a flip key that folds its blade away. Some have a separate remote that rides alongside a plain key, and newer ones use a proximity key with no blade you use day to day. The car senses that key nearby and lets you start the engine with a button.
We replace and program all of these, within what your particular vehicle allows. That last part is the honest caveat. Some vehicles are open to an independent locksmith. Others lock certain programming behind dealer-only procedures, or need details we can only confirm from the VIN. We work that out with you at the start, before any work begins, so you are not surprised later.
The names for this work vary. You may be searching for key fob replacement, remote car key replacement, smart car key replacement, or proximity key replacement. In practice they are close cousins of the same service: getting a working, properly programmed fob into your hand.
- Remote head keys and flip keys, where the blade and the remote are one piece
- Standalone remotes that pair with a separate metal key
- Proximity keys for push to start and push button start key replacement
- Spare key fob programming when you still have one working key
- Replacement after a lost, cracked, water-damaged, or stopped-working fob
Why does a dead or lost key fob need more than a new battery?
Sometimes it doesn't. If your fob has gone weak or intermittent, a fresh battery is the first thing to try, and if that is all it needs, we will tell you so rather than sell you a new fob. Many proximity keys also carry a hidden backup blade or a spot on the steering column where a dead fob can still start the car, so a dead battery is often not an emergency.
A lost fob is different. The car was paired to that specific fob electronically, so a replacement has to be programmed to the vehicle, and in many cases the lost one should be removed from the car's memory so that whoever finds it cannot use it. A cracked case or a fob that went through the wash is also a hardware problem, not a battery problem. And if you have lost every key the car came with, you are in all-keys-lost territory, which takes more steps than adding a spare. That scenario has its own page: lost car key replacement in North Hills.
Hot summers in the north-central valley also play a part. Heat is hard on batteries and plastic cases, and a fob left on a sunbaked dashboard or in a hot cupholder tends to wear out sooner than one that lives in a pocket. It is a small thing, but it explains a lot of fobs that quit in late summer.

Call (213) 577-1366How does key fob programming work, step by step?
Here is how a typical job runs with us. The details shift by vehicle, but the order stays the same.
- You call (213) 577-1366 and tell us the make, model, and year, what type of key you have, and how many working keys remain. Our line is answered around the clock.
- We confirm by VIN what your vehicle needs. If it can be done by an independent locksmith, we say so. If it is a dealer-only case, we say that too, plainly, and tell you what we can still help with.
- You choose where to do the work. Our mobile vans can come to your car in North Hills, or you can bring the vehicle to our storefront at 10740 Wilshire Blvd in Westwood.
- We verify that the vehicle is yours. Expect to show ID and proof of ownership such as a registration that matches the car.
- We prepare the new fob. If your key has a blade, it is cut to match, and the fob is readied for your vehicle's system.
- We program the fob to the car and test everything it should do: lock, unlock, trunk or hatch, panic button where fitted, and engine start.
- Before we leave, we make sure every key you have works, show you how to change the battery, and talk through whether a spare makes sense.
Can you program a key fob at my car in North Hills?
In many cases, yes. Mobile key fob programming is a large part of what our vans do. The programming equipment travels with the technician, so a car parked in a driveway, an apartment lot, or the shoulder near the I-405/Nordhoff Street interchange can often be handled right where it sits. That saves you a tow or a trip to a dealership. Our general mobile locksmith service in North Hills works the same way for other jobs.
Mobile is not always possible. Some vehicles need a procedure that only the dealer can perform, and a few situations require the car to be brought to a shop. Where data about a specific model is unclear or conflicting, we do not guess. We confirm it by VIN or in person, and we tell you the result before you commit to anything.
We are about 15 miles from North Hills at our Westwood storefront, and we serve the area with vans rather than expecting everyone to come to us. If you would rather bring the car in, the storefront is there too. Either way, you deal with one company from the first call to the finished fob.

Call (213) 577-1366What affects the cost of key fob replacement?
We do not quote numbers on a web page, because an honest figure depends on facts we do not have until we know your vehicle. Here is what moves the cost, so you can see why two fobs can be priced very differently:
- The vehicle itself. Make, model, and year determine the type of fob, how it is programmed, and what the hardware costs.
- Fob type. A basic remote is a simpler job than a proximity smart key, and the parts are priced accordingly.
- Whether you still have a working key. Adding a spare from an existing key is generally less involved than all-keys-lost programming.
- Blade cutting. Fobs with a physical blade need it cut, and some blades require more precise cutting than others.
- Dealer-only requirements. If your vehicle's security forces certain steps through the dealer, that changes both the route and the cost.
- Parts source. Factory-original fobs and quality aftermarket fobs are different products, and we will explain the tradeoff on your vehicle.
- Where and when. Coming to you costs more effort than a visit to the storefront, and a call in the middle of the night is not the same as a weekday afternoon.
- How many fobs. Programming two at once can make better use of one visit than coming back later.
Is a locksmith or the dealer the more economical route?
It depends on the vehicle, and anyone who says it is always one or the other is selling something. For many vehicles, an independent locksmith is the lighter-cost option, and it comes with the convenience of not towing the car anywhere. For others, the dealer is the only route that works. We would rather tell you that on the phone than take your money and fail.
A good way to compare is to ask each shop the same questions. Is the fob factory-original or aftermarket? Is programming included? Can it be done where the car is? What happens if the car turns out to need something more? Ask us the same set and compare the answers.
One more point worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask any locksmith for it. That is a reasonable thing to ask before anyone programs a key to your vehicle.
Why call Wilshire Lock & Key for a key fob?
We have been in business since 1987, which is long enough to have seen vehicle key technology move from simple metal keys to chips to push-button smart keys. That history does not mean every vehicle is easy. It means we know where the real limits are and will name them.
We run a physical storefront at 10740 Wilshire Blvd in Westwood and mobile service vans. When you call, you reach us, not a call center farming the job out to whoever answers a dispatch app. The company that picks up is the company that does the work. David, the owner and lead technician, oversees the work. Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round, because fobs do not usually die at convenient times.
Fob work sits inside a larger automotive locksmith service for the area, so if the fob problem turns out to be a worn ignition or a damaged key, we can say so and deal with it in one visit instead of sending you elsewhere.

Call (213) 577-1366What does a fob problem look like in North Hills?
North Hills, once known as Sepulveda, is split by the 405 into North Hills West and North Hills East, and its daily life is spread along corridors like Sepulveda Boulevard, Nordhoff Street, and Parthenia Street. The ZIP code is 91343. That layout shapes how fob problems tend to show up here.
Take the apartment clusters concentrated along Parthenia and Sepulveda. A lockout in one of those complexes is a familiar scenario, and it often involves a fob: the fob is sitting in a jacket, a bag, or the car itself, and you cannot get at the car or the door. If the fob is locked inside the vehicle, that is a car lockout first and a fob question second. If the fob is truly gone, we move to replacement and programming. Sometimes the first call turns into both jobs.
In North Hills West, gated townhome and condo communities add another wrinkle. A gate remote or building fob is not the same thing as your car key, and the two get mixed up. We program car fobs. If it is the community gate that is the problem, that is a different job, covered by gate lock repair.
The 1950s ranch tracts across both halves of the neighborhood mostly mean driveway parking, so many car fob jobs happen right at the curb or in the driveway. Nordhoff Street's business strips are another place where a van can meet a driver whose fob failed mid-workday. Wherever the car is parked in North Hills, from a 91343 ranch street to a lot near the VA Sepulveda Ambulatory Care Center, the first step is the same: a phone call and a VIN.
Should I get a spare key fob before I lose the last one?
Yes, if you can. A spare is almost always the easier and less stressful job. With a working key in hand, we can add a new fob without the extra steps that all-keys-lost programming requires. You also avoid a lockout or a no-start situation on the day you most need the car.
The difference is easy to see. Copying a fob while you still have one is a planned appointment. Replacing the last one after it vanishes is an emergency call, usually at a worse hour, with fewer options. If your car came with two fobs and you are down to one, treat that as the right time to add a spare.
Plain metal keys without chips are a different case, and a simple duplicate may be enough. For those, see key duplication in North Hills. Keys with a chip inside need programming, and that is where our transponder key programming work comes in. Fobs for push-button-start cars follow the proximity-key path described above.

We answer around the clock, every day of the year.
Call (213) 577-1366What should I have ready when I call?
A little preparation shortens the call and lets us answer more accurately.
- The make, model, and year of the vehicle, and the VIN if you can read it from the dash or door jamb
- What the key looks like: blade or no blade, how many buttons, and whether you press a start button
- How many working keys you have left, including any in a drawer at home
- Whether the car is currently running, locked, or stuck somewhere
- Your ID and proof of ownership, ready to show when we arrive or when you visit the storefront
Frequently asked questions
Can you replace a key fob for a push button start car?
In many cases, yes. Proximity key replacement and push to start key replacement are part of our work. Whether we can do it depends on the vehicle, and some models have dealer-only requirements. We confirm by VIN before any work starts and tell you plainly if your car is one of those cases.
Do you offer mobile key fob programming in North Hills?
Yes, for many vehicles. Our mobile vans bring the programming equipment to your car, so you do not need a tow or a dealership trip. When a particular vehicle cannot be done on-site, we tell you up front and offer the storefront in Westwood or explain what the dealer will need to do.
I lost my only key fob. What happens next?
You are in an all-keys-lost situation, which usually takes more steps than adding a spare. We verify ownership, confirm what your vehicle needs, prepare a new fob, program it, and where the system allows, remove the lost one from the car's memory. Call (213) 577-1366 and we can start by VIN.
Is my fob just dead, or does it need replacing?
Try a new battery first. If the fob still works intermittently or not at all, the next causes are a worn case or buttons, water damage, or a lost pairing with the car. If a battery is all it needs, we will tell you that rather than sell you a new fob.
How much does key fob replacement cost?
It depends on your vehicle, the fob type, whether you still have a working key, whether the blade needs cutting, the parts source, and whether the job is mobile or at the storefront. We do not quote numbers online. Give us the make, model, year, and VIN on the phone and we can explain what applies.
Do I have to go to the dealer for a key fob?
Not always. Many vehicles can be handled by an independent locksmith, which is often the more economical route and does not require towing. Some models do require the dealer, and we will say so honestly when yours is one of them.
Will you need proof that the car is mine?
Yes. Expect to show ID and proof of ownership, such as a registration that matches the vehicle. This protects you, because a fob programmed to your car is access to your car. Any locksmith who skips that step is not one to trust with your vehicle.
What if my fob is locked inside the car?
That is a lockout first. We open the car, then see whether the fob is fine or needs replacement. Our car lockout service handles the opening, and if the fob is damaged or missing, we move to replacement without needing a second call.
Is it worth making a spare fob if my current one works?
Usually, yes. Adding a spare while you hold a working key is less involved than replacing every key after a loss, and it protects you from being stranded. If your car came with two fobs and you are down to one, that is a good time. You can also reach us through our contact page.
