Help electrical problems

Hi I've recently bought a discovery 2 and I can only open the drivers door the others all seem to be deadlocked also no indicators!
Anyone Help?

You've pressed the button twice! Once to open the driver's door and once to open the rest?
Have you tried the door lock button on the dash too? What does that do?

It doesnt do anything
Didnt lock it twice went out yesterday morning to go into work van and I heard the stereo playing in the discovery and it wouldnt open with the fob.
Got the drivers door open with the key and it starts but cant open any other doors

First off, do you have an "Owner's Handbook" for your vehicle?
It can be downloaded along with the workshop manual from:-
http://www.myrangerover.co.uk/rave-workshop-manual/

It will show you how to use the security systems in the vehicle including the Emergency Key Access (EKA) code.
There's also some good information in this message on the forum:-
https://www.landyzone.co.uk/land-rover/handy-buying-alarm-info.311291/

Read everything including the attachments to the first message, particularly "D2 Alarm issues rev5. pdf".
In the worst case, you could well have some faulty locks, but more information would be needed to give you a reasonable idea of where to look.

Good call.
Could be any number of things.
