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.
