LR3 Doors won't lock automatically when driving
 

Up until recently, my 2006 LR3 doors would automatically lock when I start to drive. I see this as a safety feature. Now, the doors do not lock when I start to drive. The doors lock and unlock correctly with the remote phobe. Does anyone know how to reset this automatic door lock mechanism?

You would need a Land Rover scan tool to do so.

Is the FOB you are using now the same one you were using when it was auto locking?
