What a key fob replacement costs and where to get one
A replacement key fob typically costs between $200 and $500 if you go to a car dealership, or $100 to $300 if you use an independent locksmith or electronics retailer. The price depends on your car's make and model, whether the fob needs to be programmed to your specific vehicle, and who does the work. Dealerships charge more but handle everything in one place; locksmiths and retailers like Best Buy are usually cheaper but may require you to handle some steps yourself.
You have three main routes: the dealership where you bought the car, an independent locksmith, or a big-box electronics store. Dealerships will order the fob, program it to your car, and test it before you leave. Locksmiths can often do the same work faster and cheaper, though you should call ahead to confirm they stock fobs for your vehicle. Best Buy's Geek Squad and similar services can replace fobs for many common car brands, though availability varies by location and model year.
Key Takeaways
- Dealership fob replacement runs $200 to $500 and includes programming, but independent locksmiths often charge $100 to $300 for the same service.
- You will need your car's VIN (found on the driver's side dashboard or registration) and proof of ownership to order a replacement fob.
- Some fobs can be programmed by the owner using a sequence of key turns and button presses, though this varies widely by car brand and year.
- If you have a spare fob at home, a locksmith can often clone it to create a new one without needing the dealership.
- Ordering online and having a locksmith program it is usually faster and cheaper than waiting for a dealership appointment.
When you can program a fob yourself versus when you need a professional
Some car manufacturers allow owners to program a new fob without visiting a dealer or locksmith. General Motors, Ford, Chrysler, and Toyota vehicles from certain years support owner programming, usually by turning the key in the ignition a specific number of times while pressing buttons on the new fob. The exact steps differ by brand and model year, so you will need to look up your car's year, make, and model in the owner's manual or search online for your specific vehicle.
Luxury brands like BMW, Mercedes, and Audi almost never allow owner programming and require a dealership or specialized locksmith with diagnostic equipment. Hyundai, Kia, and Subaru vehicles vary by year. If you try the owner-programming method and it does not work after a few attempts, stop and contact a professional—repeated failed attempts can sometimes lock the system temporarily.
Even if your car supports owner programming, you still need to obtain the physical fob itself. You can order one online from retailers like Amazon or eBay (search your car's year, make, and model plus "key fob"), or buy one from a locksmith or dealership. The fob must be the correct type for your car, or programming will fail.
How to order a fob online and what information you will need
To order a replacement fob online, you need your car's VIN, which appears on your registration, insurance card, or the driver's side of your dashboard below the windshield. The VIN tells the seller the exact fob type your car requires. Search for "[your car year] [make] [model] key fob" on Amazon, eBay, or a locksmith's website, then verify the listing matches your VIN before buying.
Prices for fobs ordered online range from $30 to $150 depending on the brand and whether it includes programming instructions. Some sellers offer pre-programmed fobs for an additional fee, which saves you a step if your car does not support owner programming. Read the product description carefully to see whether programming is included or whether you will need to take the fob to a locksmith or dealership after it arrives.
Shipping usually takes three to seven business days. Once it arrives, test it before the return window closes—some sellers offer 30-day returns if the fob does not work with your car.
What happens at a locksmith or dealership appointment
When you arrive with your fob and proof of ownership, the locksmith or dealership will connect your car to a diagnostic machine that reads your vehicle's security system. They will then program the new fob to match your car's code. The whole process usually takes 15 to 30 minutes at a locksmith and 30 minutes to an hour at a dealership, though wait times vary.
At a dealership, you may need to schedule an appointment in advance, especially if you go during business hours. Many dealerships can fit in fob programming same-day if you call ahead. Locksmiths often work by walk-in or same-day appointment and may come to your home or workplace if you prefer. Some locksmiths charge a service call fee on top of the fob price if they travel to you.
Before you leave, the technician will test the fob to make sure all buttons work—lock, unlock, trunk, and panic. If anything does not respond, they will reprogram it or replace it under warranty.
Cloning an existing fob if you have a spare at home
If you have a working spare fob, a locksmith can clone it to create a new one without ordering from the dealership or manufacturer. Cloning copies the security code from your existing fob to a blank fob, which is faster and sometimes cheaper than ordering a new one. The locksmith will need both the working fob and the blank fob, plus your car keys to test the clone.
Cloning works best for older cars and some mid-range brands. Newer luxury vehicles and high-security systems may not allow cloning, in which case the locksmith will tell you upfront. Cloning usually costs $50 to $150 and takes 20 to 30 minutes.
What to do if your fob is lost or stolen
If your fob is lost or stolen, you do not need to replace your car's locks or security system—the fob is just a remote control, not a key to the ignition. However, you should order a replacement fob soon so you have a working remote. A thief with your fob can unlock your car but cannot start the engine without your physical key or the car's security code.
If your fob was stolen along with your car keys or registration, contact your insurance company and local police to report the theft. Some insurance policies cover key fob replacement, though many do not. Check your policy or call your agent to ask.

Frequently Asked Questions
Can I use a universal key fob instead of buying one for my specific car?
Universal fobs exist but rarely work well. They can lock and unlock some cars, but they often do not control the trunk, panic button, or other features. Most car security systems reject universal fobs after a few uses. Buying a fob made for your specific car model is more reliable and only slightly more expensive.
What if I lost my fob and do not have a spare?
You can still drive your car using your physical key in the door lock and ignition. Order a replacement fob online or visit a locksmith or dealership to get one programmed. In the meantime, you will just use the key manually instead of the remote.
Does my car insurance cover key fob replacement?
Most standard car insurance policies do not cover key fob replacement. Some comprehensive plans or roadside information add-ons may include it, but you will need to check your policy or call your agent. It is usually cheaper to pay out of pocket than to file a claim.
How long does a key fob battery last?
Most fob batteries last three to four years with normal use. If your fob stops working, try replacing the battery first—it costs $5 to $10 and takes two minutes. If a new battery does not fix it, the fob itself may be damaged and need replacement.
Can a locksmith program a fob I ordered online?
Yes. Most locksmiths will program a fob you bring them for $50 to $100, even if you did not buy it from them. Call ahead to confirm they have the equipment for your car brand, and bring your car keys and proof of ownership to the appointment.
