What does key fob replacement actually involve?
A key fob is a small computer in a plastic shell. Inside is a radio transmitter, a battery, and usually a transponder chip that the car checks before it lets the engine run. Replacing one is more than cutting metal. The new fob has to be matched to your specific vehicle, and the car has to be told to accept it. That second step is the programming, and it is the part most people cannot do themselves.
Most calls we get in Glendora fall into a few groups. Someone has lost the only fob they own. Someone's fob has stopped working, and a fresh battery did not fix it. Someone's fob got cracked, soaked, or run through the wash. Or someone only has one fob and wants a spare before the day it disappears. All four are the same basic job, but the urgency and the method change depending on whether you still have a working key to copy from.
If you have no working key at all, the job is called an all-keys-lost situation, and it takes more steps because the car has to be introduced to a new key from scratch. If you have one working fob, adding a spare is usually simpler and the lighter-cost route. That is a good reason to call us before the last fob goes missing, not after.
Which kinds of key fobs do we replace and program?
The names for these keys are inconsistent, so here is how we sort them when you call. Tell us the year, make, and model, and we will work out which type your car uses.
- Remote head keys and flip keys: a metal blade with the lock, unlock, and trunk buttons built into the head. These carry a transponder chip and often need both cutting and programming.
- Separate remotes: a fob that only operates the door locks, paired with a standard transponder key. The remote and the key are programmed separately.
- Proximity keys, also called smart keys or keyless-entry fobs: you keep the fob in a pocket or bag and the car senses it. This is the usual setup for a push-to-start or push-button start vehicle.
- Emergency blade inserts: the hidden metal key inside many smart fobs. We can cut a replacement blade when yours is missing or worn.
- Spare key fobs: a duplicate added to a car that still has a working key, so you are not down to a single point of failure.

Call (213) 577-1366How do we replace and program a key fob?
Every job is a little different, but the sequence below is how we run most of them. We can do it at our Westwood storefront or bring the equipment to you in one of our mobile vans.
- You call (213) 577-1366 and tell us the year, make, and model, plus whether you still have any working key. We also ask for the VIN, which is on the lower corner of the windshield and on your registration or insurance card.
- We confirm what your vehicle needs. Some cars accept an aftermarket fob, some need a specific original-style part, and a few can only be handled through the dealer. We tell you which category yours is before any work starts.
- We verify ownership. A locksmith should not make keys for a car without seeing proof it is yours, so be ready with your ID and registration or title.
- We prepare the new fob. That can mean cutting the emergency blade or key, and loading the right frequency and chip information.
- We program the fob to the vehicle using professional diagnostic equipment, then pair any additional fobs you want added at the same visit.
- We test everything with you: lock, unlock, trunk or hatch, panic button if equipped, and engine start. For a push-button start car, we test that the car recognizes the fob inside the cabin.
- We explain how to store the spare, and what to do if a fob is ever lost, so the old one can be removed from the car's memory when that is possible.
What affects the cost of key fob replacement in Glendora?
We do not quote numbers on a web page, because honest pricing for a fob depends on facts we need to know about your car. Here is what moves the cost up or down, so you can compare any quote you get, ours included.
- The vehicle itself. Make, model, and year decide what hardware and programming access is required. Basic remotes are a different job from encrypted smart fobs.
- The type of fob. A plain remote costs less to supply than a proximity key with a built-in emergency blade.
- Whether you have a working key. Copying from a working fob is usually the more economical route. An all-keys-lost job takes more labor and sometimes more equipment.
- The part itself. An original-style fob and an aftermarket fob are not priced the same, and not every car accepts both.
- Where the work happens. Coming to our storefront is the lighter-cost option when your car can be driven. A mobile visit adds travel, which matters in a city about 37 miles from our Wilshire Boulevard base, but it saves a tow if the car will not move.
- Time of day. Nights, weekends, and holidays involve a technician being pulled out of a normal schedule.
- How many fobs you want. Programming a spare during the same visit is usually more efficient than coming back later.

Call (213) 577-1366Will I have to go to the dealer?
Sometimes, and we would rather tell you that up front than waste your afternoon. Some manufacturers lock programming behind dealer-only tools or require codes that are not available to independent shops for certain model years. Some newer vehicles also need the fob ordered by VIN, which takes extra time no matter who does the work.
We do not guess about this. Chip types, frequencies, and programming access vary by vehicle, and published information is not always consistent or current. So we confirm by VIN and, when needed, in person with the car in front of us. If your vehicle turns out to be a dealer-only case, we will say so plainly. If we can do the job, we will tell you what it involves and what it depends on.
If you are weighing the options, the dealer route often means arranging a tow and waiting on an appointment. A mobile locksmith comes to the vehicle, which can be easier when the car cannot be started. Neither is right for every situation, and the VIN is what settles it.
Key fob replacement around Glendora: where we get these calls
Glendora is a spread-out city, and the places where fob trouble happens are very different from one end to the other. The data we work from points to a few patterns that match what a mobile fob service is built for.
Near Citrus College, students park in daily lots and live in nearby housing, and a dead or lost fob can strand someone on campus with no easy way home. If the car is locked with the key inside, our page on car lockout service in Glendora covers that situation. If the fob itself is gone, we can bring a replacement and program it at the car. At the Glendora A Line park-and-ride, a commuter who drops a fob or finds it dead at the end of the day needs the car running before the evening, and we can meet them in the lot.
In the foothills, homes in neighborhoods such as Morgan Ranch, Gordon Highlands, and Silent Ranch Estates tend to have longer driveways, gates, and cars that stay parked at home for a while. A spare fob for a household with two drivers is easier to arrange at home than during an emergency. In the 91741 area we regularly hear from owners who want a second fob added before a trip. Closer to the Village, the 91740 ZIP covers Glendora Village shoppers and merchants, and a fob that dies while someone is parked near the shopping district is a very ordinary reason to call.
Neighbors along the Route 66 (Alosta Avenue) corridor often live in condos and apartments with shared garages, where there is little room to wait around for a tow. A mobile visit that handles the fob in the parking space tends to be the practical option there. For a more detailed picture of the area we cover, see our locations page.

Call (213) 577-1366Smart key and push-button start questions we hear most
Push-to-start cars confuse people because the fob never goes in a slot. A few things are worth knowing before you call.
When a proximity fob stops working, the cause is often the battery, and replacing the coin cell is something many owners can do themselves. If a new battery does not help, the problem might be a damaged circuit board, a fob that was dropped or exposed to moisture, or a fob that has lost its pairing. We can tell the difference quickly, and we will not sell you a new fob if a battery or a re-sync solves the issue.
Many push-button start cars include a backup way to start the engine if the fob battery is dead, such as holding the fob against the start button or a marked spot in the cabin. The exact method depends on the car, and your owner's manual shows it. If you are stuck in a parking lot, that is worth a look before you call.
A damaged ignition or start system is not a fob problem, and a new fob will not fix it. If the car still will not start after a fresh, programmed fob, the issue may be in the ignition or the car's electronics. Our ignition repair page explains that side of things, and we will tell you honestly when the fob is not the cause.
Why call Wilshire Lock & Key for a key fob?
We have been in business since 1987, and key fobs have changed a great deal in that time. The core of the work has not changed: figure out exactly what the vehicle needs, do the job right, and be straight about what it will take.
We are one company. When you call (213) 577-1366, you reach us, not a call center that hands your job to whoever accepts it. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so you can drop off a car or have us come to you. David, the owner and lead technician, oversees our work, which means there is a person you can hold accountable for how it is done.
We answer around the clock, every day of the year. If you need help in the middle of the night, our 24-hour locksmith service in Glendora is the same team. And since California requires locksmith companies to hold a BSIS LCO license, you should ask any locksmith you consider, including us, for the license number. Do not hire anyone who dodges the question.

Call (213) 577-1366How to avoid being stuck with one fob
The easiest fob problem to solve is the one you handle before it becomes an emergency. If you have only one fob, get a spare now. Programming a second fob while the first still works is generally simpler and less costly than an all-keys-lost job later.
Keep the spare somewhere separate from the original and away from the car. Do not leave it in the glovebox, since a thief who gets into the car gets the fob. Replace fob batteries when the range starts to shrink, not when the fob dies. And if a fob goes missing, call us sooner rather than later, since a lost fob can in some cases be removed from the car's memory so it can no longer start the vehicle.
For related work, our car key replacement and lost car key replacement pages explain what happens when the whole key is the problem, not just the remote. If your car uses a chip key without a remote, see transponder key programming. To have the work done where your car is parked, read about our mobile locksmith service.
Frequently asked questions
How much does key fob replacement cost in Glendora?
It depends on your vehicle, the type of fob, whether you still have a working key, and whether you come to us or we come to you. Copying from a working fob is usually the more economical route. Call (213) 577-1366 with your year, make, and model, and we will explain what applies to your car.
Can you program a key fob at my house or workplace in Glendora?
In most cases, yes. Our mobile vans carry programming equipment, so we can work at your driveway, a campus lot, or a park-and-ride. Some vehicles are dealer-only, and we confirm that by VIN before any work starts.
I lost my only key fob. Can you still make a new one?
Often we can, though it is a bigger job than copying from a working key. We confirm ownership, identify the correct fob by VIN, and program it to the car. Some makes require dealer involvement, and we say so plainly if yours is one of them.
Do you replace push-button start and proximity keys?
Yes, for the vehicles we can support. Push-to-start fobs are more complex than basic remotes, so we confirm the exact fob and programming method by VIN or in person before committing to the job.
Is it cheaper to go to the dealer or a locksmith for a key fob?
It varies by vehicle, so we will not make a blanket claim. A locksmith visit can avoid a tow and a dealer appointment, which is often what makes it more economical. For certain cars, only the dealer can do the programming, and we will tell you.
Will a new battery fix my fob?
Often, yes. A weak coin-cell battery is the most common reason a fob stops working or loses range. If a fresh battery does not help, the fob may be damaged or out of sync, and we can diagnose it.
What do I need to have ready when I call?
Your vehicle's year, make, and model, the VIN if you can find it, and whether you have any working key. When we arrive, you will need ID and proof of ownership such as registration or title.
Can you add a spare key fob if I still have one that works?
Yes. This is usually the simplest and lighter-cost version of the job, because the car already recognizes your existing fob. It is a good idea to do it before the original is lost.
If my car won't start after a new fob, what's wrong?
The fob may not be fully programmed, or the problem may be somewhere else, such as the ignition or the car's electronics. We test the fob with you at the vehicle, and if the issue is elsewhere, we will tell you instead of selling you another part.
Do you take calls at night or on weekends?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, all year, and the same company handles the call from start to finish.
