Hey guys!
got a 2014 xjl supercharged on my hands... very bad problems since day 1.

ran into a major issue.. car won’t recognize my keys at all. Unable to even connect to the car via OBD can’t reprogram new keys. Any ideas??

all grounds are good, new batteries, continuity and power running through all wires from front to back. Shop had my car for 2 months and was unable to solve anything.

 

Sorry to hear but cant understand why you cant connect to the car via OBD

 

Check the fuse to the KVM (Key Vehicle Module). If the car can't see the key, it can't be reprogrammed. Check my recent thread labelled "KVM'. In my case the car had lost synch with the key.

Passenger compartment F37 20Amp. Worth checking it's the same for your car MY
