2005–2007Confirm the exact fit by FCC ID or part number before ordering.
Aftermarket. Every key and remote we publish is quality aftermarket — it is not a genuine dealer part, and we never list it as one. The codes below are how you confirm the exact part before you order.
Ships unprogrammed. Like any replacement key, it has to be programmed to the vehicle before it will operate. Programming method, tooling and PIN access vary by vehicle, year and platform, so we don’t publish per-vehicle procedures or tool compatibility here — match the part on the codes below and use your usual process for that platform. Not sure? Email the trade desk with the VIN or year/make/model before you order.
If it won't program on the listed vehicle, we refund it and pay the return freight. Two conditions only: the vehicle matches this listing, and the part comes back in resaleable condition — a blade cut only to turn the ignition for the programming attempt doesn’t void it. Reply with the vehicle, the tool you used and the error, and we send the return label. Read the guarantee.

How to verify this keyless entry remote fits
- Check the FCC ID on the customer’s existing keyless entry remote — it is printed on the case, often under the battery cover — against M3N65981403.
- On Canadian-market remotes the IC certification number should read 267F-65981403.
- Match a cross-reference: 15212382.
- Confirm the frequency is 315 MHz — remotes on a different frequency are not interchangeable even when the shell looks identical.
- Count the buttons: this keyless entry remote has 5.
- Confirm the vehicle is the one in the fitment table on this page.

If it doesn't program, it's on us
Every listing carries its FCC ID, part number and cross-references, so you can match the part in your hand before you order — and the trade desk will confirm it with you if you're not sure. If a key or remote you bought for the vehicle we listed it against still won't program, tell us within 30 days of delivery: we refund it and we pay the return freight. Two conditions, both fair — the vehicle matches the listing, and the part comes back in resaleable condition.
