2003 disco all doors are locked and neither the remote or key will open any doors could be superlocked

SOURCE: 1996 4.0 Range Rover won't unlock

This car is in super lock mode... when you press remote 2times to lock or when you lock with remote and try to unlock using key manually.

there is a 4 digit number to open the door, its like opening a safe, starting from the left(key in car door) it goes L/R/L/R. so if number code is 1234..... left 1, right 2, left 3, right 4.

or if this too troublesome you can ask landrover dealer to remove the KEYCODE.

happy trying.....

There are 2 possibilities. First, if you have the EKA code, this is the emergency key access code, a 4 digit number. You must lock down the car including windows and then with the key enter the code using the door lock on the drivers side. Note that if you miss with the code 3 times, then you will have to wait about half an hour to let the system reset, before trying again. Check your vehicle service books to find the code, maybe on a seperatre card. The only other option is to recdover the car to an authorised dealer that can plug in the tester to reset the system.
Hope this helps

SOURCE: i have disco 2004 left

sound like the out side door handle either broke or got lose at the rod which connects to the door latch

SOURCE: doors will not open using remote or disarm alarm.

You must enter the system using the EKA code, it will written in the service book how to activate the EKA. If you dont have the EKA code, you will have to take the car to the dealer to reset the system and give you the code. hope that helps
