That code 12 indicates a corrupt signal from the transceiver. This can be a bad key or problem with the transceiver. This is the part that reads the key code. It is located around the ignition cylinder. We should check the connction to it so I recommend we remove the steering column covers to check it. Let me know.
I would lean towards the transceiver but still could be a poor connection. Unfortunately there is not much we can test on the secrity system without the Jag factory tool.
That number does not cross over in my system.
It can be a bad key or cluster. Unfortunately a Jag factory tool is needed to do any security or key programming.
Unfortunately without a Jag tool we do not know if the cluster and/or ECM are communicating the security info.
