It's printed on the back of the fob, or inside the battery compartment. It usually starts with letters and ends in numbers, like EZSDEI7756, VA5REH300-1WAM or NAHAS2501.

Try a fresh battery first. A flat cell and a dead fob behave identically from the driver's seat, and a battery costs a few dollars. Every fob page lists the exact cell it takes, and you'll find them all in our key fob batteries.

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. Where neither exists, a new key fob kit will often pair to the control module you already have, so it isn't a full system replacement. Each discontinued fob's page shows which applies, and you can see them all on Discontinued Key Fobs.
