The engineers at Range Rover went over board developing this alarm system. The only way to disable the alarm system is to send your BECM (Controller) to a company called Remote key or similar co and they can reprogramme using a Rovacom or similar. Have you tried using the EKA method to mobilize your vehicle? (EKA is a sequence of turns in the drivers door with your key) Hope this helps.
