Will the remote unlock the vehicle? Does the touchscreen display turn on open the driver door? Does the hazard switch illuminate with the door open?
Customer: replied 1 year ago.
remote doesn't unlock doors (only switch that works on remote is the lights) touchscreen displays only the jaguar image - don't remember is hazard switch is on or note

OK this could be a battery issue or problem with one of the modules that control the vehicle security systems. Even though you have a jumper on the battery if it has a bad cell it still can cause a voltage loss. I recommend we disconnect the battery and have it fully charged. You can disconnect the battery and place the jumper box directly. To the battery cables to see if the locking will work.
