What is 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 replacement works. A remote key fob is the small plastic unit with lock, unlock and trunk buttons, often attached to a metal key blade. A smart key, also called a proximity key, is the kind that stays in your pocket or bag. The car senses it nearby and lets you open the door and start the engine with a push-button-start switch. Both are small computers that have to be introduced to your specific vehicle before it will trust them.
Replacing one is really two jobs: getting a physical fob that is compatible with your vehicle, and programming it so the car accepts it. Buying an unprogrammed fob online and hoping for the best is where many people lose a week and some money. We start with your year, make, model and VIN, work out what the car actually needs, and tell you plainly whether we can do the job on site.
That last part deserves honesty. Many vehicles can be handled by a mobile locksmith with the right equipment. Some cannot. Certain makes and model years lock key programming behind dealer-only procedures or factory security codes that we can't always reach. We don't guess about that. We confirm by VIN and by looking at the car in person, and if yours turns out to be a dealer-only case, we tell you before you spend anything.
If what you actually need is a whole new key rather than just the remote part, that is a slightly different job, covered on our car key replacement page. This page is about the fob itself: remotes, proximity keys and push-button-start keys.
Why do Long Beach drivers end up needing a replacement fob?
The reasons are ordinary, and most of them are things nobody plans for. A fob rides in a pocket, a purse or a beach bag, gets dropped on concrete, goes through the wash, or sits in a cup holder next to a spilled drink. Long Beach is a coastal city where marine layer and salt air are part of daily life, and small electronics that spend time near the water, the marina or the shore are not helped by it.
Here are the situations we hear about most often:
- The fob is lost and you still have a spare, so you want a second one made before the spare disappears too.
- The buttons are worn through or the case has cracked, and the fob works only when you press it just right.
- You replaced the battery and it still does nothing.
- The fob went through the wash, got wet, or sat in a bag after a day at the beach.
- The car shows a key-not-detected message, or the doors unlock but the engine will not start with the button.
- You bought a used car and it came with one fob, or none at all.
- The fob was working fine and then stopped, with no obvious cause.

Call (213) 577-1366Try the battery first: what we will tell you before replacing anything
A dead coin-cell battery is one of the most common reasons a fob seems to fail, and it is the lighter-cost fix. If your fob has gone quiet, check whether the case opens and what battery it uses. Swapping it is often a few-minute task at a kitchen table. Many smart keys also have a hidden emergency blade or a spot on the steering column or start button where you can hold the fob to start the car when the battery is weak. Your owner's manual will show where it is for your vehicle.
If a fresh battery doesn't help, the problem might be a damaged circuit board, a worn button contact, or a fob that has lost its pairing with the car. Those are the cases where replacement and reprogramming make sense. When you call, tell us what you've already tried. We would rather save you a service call than sell you one you don't need.
How do we replace and program a key fob step by step?
The process is simple in outline, though the details vary by vehicle. This is how a typical job runs when we can complete it on site.
- You call (213) 577-1366 at any hour and give us the year, make and model of the car, plus where it is parked. If you can read the VIN from the base of the windshield on the driver's side or the door jamb sticker, that speeds everything up.
- We identify what type of fob your car uses: a remote with a blade, a proximity key, or a push-button-start smart key. We also tell you whether the job can be finished by a mobile technician or needs the dealer.
- We confirm ownership. You will need your ID and proof the vehicle is yours, such as the registration or title. We do this for every vehicle, and it protects you as much as it protects us.
- We supply a compatible fob and, if your key has a blade, cut it to match. If the fob has to be prepared or matched to your vehicle before it can be paired, we do that first.
- We connect programming equipment to the car and register the new fob so the vehicle accepts it. On some vehicles every existing fob must be registered again during the same session, so keep every fob you have on hand.
- We test everything: lock, unlock, trunk or hatch, panic button if equipped, remote start if equipped, and starting the car with the button or the ignition. We also check that your existing fobs still work and that the emergency blade opens the door.
- You get the fob, the old ones back, and a plain explanation of what we did and what to do if anything acts up.

Call (213) 577-1366Can you do mobile key fob programming where my car is parked?
In most cases, yes. We run mobile service vans in addition to our storefront, so the equipment comes to the car instead of the car going to a shop. That matters for fobs, because a driver without a working key often has a vehicle that cannot be driven safely, and towing a car to a dealer just to have a small electronic part paired is a hassle most people would rather skip. Our mobile locksmith service is the same company, the same technicians and the same phone number.
There are two honest limits. First, the dealer-only vehicles mentioned above: for those, we say so on the phone or after a VIN check, rather than showing up and finding out. Second, some vehicles are simply easier when they are in front of us. If the VIN or the car's own system gives us conflicting information about what kind of fob it takes, we confirm in person before we order or prepare anything. We would rather take a few extra minutes to get it right than program the wrong part.
If you also need to get into the car, that is a separate problem with its own page. See car lockout for how we handle it. Often we can solve both in the same visit.
What affects the cost of key fob replacement in Long Beach?
We don't quote numbers on a web page, because honest pricing depends on your exact vehicle. What we can do is tell you what moves the cost up or down, so that when you get a quote from us or anyone else, you can tell whether it makes sense.
- The type of fob. A basic remote usually costs less than a proximity key or a push-button-start smart key, which contain more electronics.
- Year, make and model. Some vehicles use parts that are easy to source, and others use parts that are scarcer or tied to the manufacturer.
- Whether you have a working key already. Adding a fob when you still have one working is generally simpler than starting from nothing.
- Whether all keys are lost. That is a bigger job on many vehicles and can need extra steps; see the section on spares below.
- Whether a blade must be cut, and how complex it is.
- Dealer-only procedures. If a vehicle requires the dealer for part of the process, that portion is outside our control and we will say so.
- Where and when you need us. Mobile service means we travel to you, and a call in the middle of the night is handled differently from a planned appointment.
- Whether you supply your own fob. Some customers buy one online; we can often use it, but compatibility and quality vary and we cannot promise a particular part will work.

Call (213) 577-1366Why is a spare key fob worth having before you lose the last one?
The simplest advice we give is this: get a spare fob while you still own a working one. Duplicating from a working fob is almost always the more economical route. If every key is lost, the situation turns into something more involved, because the car has nothing to learn from, and on some vehicles the process takes longer and may involve the dealer. A spare made now is a routine appointment. A spare made after the last fob disappears can mean a bad day.
Think about who else drives the car, too. A second driver in the household, a roommate sharing a parking space, or an adult child using the family vehicle are all reasons to have a properly programmed spare instead of passing one fob around. Keep the spare somewhere you can reach, but not inside the car.
If you are already past that point and have no working key at all, go to our lost car key replacement page, which covers that situation directly. If your vehicle uses a chip key without remote buttons, transponder key programming is the better match.
Key fob replacement across Long Beach: where we get called
Long Beach is a spread-out city, and fob calls come from every part of it. Downtown, East Village and Alamitos Beach have a lot of apartment and condo living, where cars sit in shared garages or on the street. A lost or failed smart key in a building like that is a particular headache: the car is boxed in, you may be on a deadline, and the garage is not a place you want to wait around. We can come to the vehicle and do the programming in place, provided the car type is one we can handle on site.
Near the water, in Belmont Shore and Naples, salt air and marine layer are a regular part of life, and the coast is hard on exterior hardware generally. We see the same wear pattern with fobs that live in beach bags and wet pockets: cracked cases, corroded contacts and buttons that stop responding. If a fob in Belmont Shore or Naples has started acting up, replacing it before it fails completely is the less stressful route.
Farther inland, areas like Bixby Knolls, Rose Park and Los Altos are quieter, but the need is the same. Anyone with a single remaining fob, a car bought used without a spare, or a fob that quit after a drop should get a second one made. The ZIP codes we regularly serve include 90802, 90803, 90804, 90807, 90808 and 90815, and we cover the rest of Long Beach as well.
For students and renters near California State University, Long Beach, the usual story is a shared or inherited car with one worn fob, and a plan to fix it later that never arrives. If that is you, a spare now is far easier than a lost-key situation in the middle of a semester.
We are upfront about distance. Our storefront is at 10740 Wilshire Blvd in Westwood, roughly 30 miles from Long Beach, and our vans are what bring the service to you. When you call, we will tell you plainly how we can handle the job based on your location and the vehicle.

Call (213) 577-1366What if the new fob works but the car still will not start?
Sometimes the fob is not the whole story. If the new fob locks and unlocks but the car refuses to start, or the key turns with resistance, or the ignition feels loose or sticky, the problem may be in the ignition or the starting circuit rather than the key. That is a different repair, and we would rather say so than keep programming fobs. Our ignition repair page explains what that involves.
Likewise, if you are locked out and the fob is inside the car, or the fob is dead and the doors won't open, you may need entry first and programming second. And if the problem turns out to involve a broken blade in a lock, or a larger vehicle key issue, we will point you to the right service. Staying focused on what the car actually needs is part of doing this honestly.
Why call Wilshire Lock & Key for a key fob
We have been in business since 1987, and in that time the way cars use keys has changed from metal blades to chips to proximity fobs and push-button starts. We have worked through each of those changes. We are one company with a storefront and mobile vans, not a call center that passes your job to whoever picks it up. When you call (213) 577-1366, you reach us, at any hour, any day of the year. David, the owner and lead technician, oversees the work.
That structure matters for fobs. A fob job depends on getting the right part, reading the vehicle correctly, and being honest when a car is dealer-only. If a dispatcher is relaying messages to a stranger, details get lost. We keep that chain short.
On licensing: California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. You should ask any locksmith for their license number before work begins, and you are entitled to look it up. That is good advice no matter whom you call, including us.
Our broader automotive work, including lockouts, key cutting and ignition problems, is described on our automotive locksmith page.
Frequently asked questions
How much does key fob replacement cost in Long Beach?
It depends on the vehicle, so we don't post a number. The main factors are the type of fob (a basic remote versus a proximity or push-button-start key), your year, make and model, whether you still have a working key, whether a blade must be cut, and whether any dealer-only step is involved. Call (213) 577-1366 with your VIN and we will explain what applies to your car.
Can you program a key fob at my location in Long Beach?
Often yes. Our mobile vans carry the equipment to the car, so you do not need to tow it anywhere. Some vehicles are dealer-only for key programming, and we tell you that honestly after confirming the VIN or checking the car in person.
Do I need my original fob to get a replacement?
Not always, but having one makes the job simpler. Adding a fob when you still have a working one is usually more straightforward than starting with none. If every fob is lost, the process can involve extra steps depending on the vehicle.
What do I need to show you to prove the car is mine?
Bring your ID and proof of ownership, such as the registration or title. We ask this for every vehicle. It protects you from someone else getting a working key to your car.
Can you replace a push-button-start or proximity key?
In many cases, yes. Smart keys and proximity keys contain more electronics than a basic remote, and some vehicles require procedures that only the dealer can do. We confirm by VIN and in person before promising anything, and we say so plainly if your car is a dealer-only case.
I lost one of my fobs. Will the lost one still start my car?
That depends on the vehicle. On some cars, programming a new fob also lets us remove a lost one from the car's memory, and on others it does not work that way. Ask us when you call and we will confirm for your vehicle.
Can I buy a fob online and have you program it?
Sometimes. Online fobs vary in quality, and some are the wrong type for your car or cannot be paired at all. Call us before buying so we can tell you what to look for. We cannot promise a part we did not supply will work.
Should I go to the dealer or a locksmith for a key fob?
For many vehicles, a mobile locksmith is the more convenient route, since we come to the car. For vehicles with dealer-only procedures, the dealer is the right place and we will tell you that. Either way, ask for a clear explanation of what is being done and what affects the cost.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for their license number before work starts and verify it. A legitimate company will give it to you without hesitation.
