What actually differs between an OEM and an aftermarket fob?
The parts that make a key fob work with your car are the radio frequency, the transmitter chip and the button layout. The FCC ID printed on the back of your fob identifies that combination. An aftermarket fob built to the same FCC ID and part number talks to your car on the same frequency and is programmed with the same procedure. What differs is who manufactures it: an OEM key comes from the car brand’s supplier and carries its logo, while an aftermarket key is made by a third party. The case, buttons and battery door may look slightly different.
How much can you save?
These are UrbanX’s current in-stock prices by key type, compared with typical dealer pricing:
- Transponder keys (turn-key with a chip): most $15.50–$21.50. Shop transponder keys
- Remote key fobs (lock/unlock buttons): typically $21.50–$45, median about $28. Shop key fobs
- Smart keys (push-to-start / proximity): mostly $38.50–$61. Shop smart keys
Even after paying a locksmith $50–$100 to program a key, the total usually stays well below the dealer price. For a full breakdown see car key replacement cost: dealer vs locksmith vs DIY.
Will an aftermarket key fob work as well as the original?
It will when it is the right match. Before you order, compare three things with your current key: the FCC ID (printed on the back or inside the battery cover), the part number, and the number and layout of buttons. Our FCC ID lookup guide shows where to find these, and the VIN lookup finds the right key from your vehicle identification number. If your key has a metal blade, a locksmith or hardware store cuts the new blade to match your original.
Programming: DIY, locksmith or dealer?
Many vehicles support onboard programming that takes 2–5 minutes with no tools; UrbanX includes free step-by-step instructions. Newer push-to-start vehicles usually need a locksmith with a programming tool, typically $50–$100. A dealer can program any key, but it is the most expensive option. See the DIY programming guide, and if you are unsure which type you have, read transponder key vs smart key vs remote.
When a dealer key makes sense
- Your car is still under warranty and the dealer is replacing the key as part of a covered repair.
- Your model is very new and no aftermarket key with a matching FCC ID exists yet.
- You have lost every key and want the dealer to cut, program and verify everything in one visit.
For everyone else, a matched aftermarket fob plus DIY or locksmith programming is the lower-cost route.
Real-world examples
- Consumer Reports bought a key fob online for a 2017 Hyundai Ioniq for $79.95; the dealer wanted $236.45 for the same part. With $120 paid to a locksmith for programming, CR’s total was $272.42, about $156 less than the dealer’s $428.92 quote. The lesson: pricing the part and the programming separately can cut the bill a lot. Consumer Reports, May 2019
- In December 2025, CBS12 News in Florida reported on a Chevrolet owner whose dealer quoted $400 for a new fob ($200 for the part and $200 to program it). He found a locksmith who would do it for less. The station found replacement fobs on Amazon for $9 to $30 and advised checking the battery first and not making the dealer your first stop.

Frequently asked questions
Is an aftermarket key fob the same as OEM?
It is not made by the car manufacturer, but a correctly matched aftermarket fob uses the same FCC ID, frequency and button layout, so it is programmed and used the same way.
Will an aftermarket key fob void my warranty?
In the U.S., using a replacement part does not by itself void a vehicle warranty; a manufacturer would need to show the part caused a problem. Check your warranty terms if you are unsure.
How do I know which key fob fits my car?
Match the FCC ID and part number on your current key, or use the VIN lookup. Every UrbanX listing shows the FCC ID and part number it replaces.
