Confirm 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.

Best-Price Guarantee
Found it cheaper? We'll match it.
See the same in-stock part advertised for less by another Canadian or U.S. trade supplier? Send us the listing before you order and we'll match the price — we'd rather earn the reorder than lose it over a dollar.
- Same item, in stock, from a verified trade supplier
- Current advertised price — send the link or a screenshot
- Excludes clearance, liquidation, auction and obvious pricing errors
How to verify this smart key fits
- Check the FCC ID on the customer's existing smart key — it is printed on the case, often under the battery cover — against IYZFBSB802.
- Match the part number 8T0959754G,8T0959754B,8K0959754B,; it is also cross-referenced as 4G0959754G, 4H0959754G or 4H0959754DB.
- Confirm the frequency is 315 MHz — remotes on a different frequency are not interchangeable even when the shell looks identical.
- The transponder chip is PCF79** / HITAG 2 / 46 CHIP.
- Count the buttons: this smart key has 4.
- Find the vehicle in the 7-row fitment table on this page; year ranges and trims matter.

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.
