Hi There, I'm Clayso a certified master automobile technician with 30 years of automotive repair and diagnostic experience.

P1260 indicates the immobilizer is active, if you have a different key try it first. Most likely the ignition switch has failed. P1260 sets when the Instrument Cluster loses its coding or can't communicate with the ECM. Once the ignition switch is replaced the instrument cluster may have to be reprogrammed with a Jaguar compatible scan tool.

I hope this information is helpful. If you have any questions let me know. You can reply back to me through this thread at any time.
