Land Rover Repair: 2000 Range Rover wont start, pushbutton, range rover

Question
I have a Range Rover 2000 4.0 SE I change the battery after that it won't start center display 'ENGINE DISABLE'
what can I do to get the car start?  Any suggestion I will appreciate it.

Answer
Lock and unlock the vehicle with the pushbutton remote.  If that fails, put the key in the driver door, twist to lock while pressing lock.  Hold 5 seconds.  Repeat for the unlock direction.  Press unlock on the fob, and the truck should start provided it responded to the unlock press.

If it does not respond you will need a dealer or LR specialist with a T4 or Autologic system
