Ok here goes. Started just after lockdown First fault unable to unlock car with key button. Tried new batteries. Didn't work. So had to use smart key socket. Then this stopped working. Called breakdown out unable to do anything. Towed car to garage( main dealer closed) they tried reprogramming key but couldn't. Found a local guy with jaguar programming equipment he managed to reprogram the car by doing a module at a time. He managed to get it back to smart key docking starting but can not understand why it will not programme the passive side tried new car battery (old one not powerful enough) new KVM, a different BCM and new keys also a different remote aerial. The vehicle recognise that there is 3 keys for the car. Not sure taking it to the main dealer is going to do any good as the equipment they have is the same as the one we are using. Has anybody had the same problem.
thankyou in anticipation
