No. It has to be paired to your system first. Most systems can be programmed by the owner in a few minutes, and each fob page links the guide. If you'd rather not, book a visit and we'll pair it at our Markham shop.

There's usually still an answer. Some have an exact replacement under a different brand with the same FCC ID. Others have a fob that works with the antenna already in your vehicle.

Each discontinued fob's page shows which applies, and you can see them all on Discontinued Key Fobs.
