Hi,

It could be a few things. For example, the key itself, the receiver, or the ignition switch itself. What you need to do is scan the can-bus to determine if codes are stored by any of the modules on the vehicle.

CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know if that is something you can do or have done.

Take care,

Joe
