I have a 2006 Land Rover Range Rover that when the truck is off and the key is out of the ignition, the dash says "key in ignition", radio still works, and the power windows work. Replaced battery and the BCM (with programming). Any other suggestions on how to fix this problem?

 

Problem was solved by cleaning electrical connections in passenger floor board. Went bad from corrosion due to water leaking in. Now the alarm goes off periodically even when it is disarmed.
