Yesterday, I went to unlock the door and nothing happened, turned the key and nothing happened. Was able to get in thru the window. When i tried the door unlock switch, nothing happens. with the key in the ignition all the lights flash but ignition does nothing. Any ideas? Battert is fully charged and cable connections are good.

 

Try resetting the alarm system buy turning the key in the door and turning it three times to unlock.

 

i tried this to no avail, open to any other ideas

 

what year and model?

 

How do you know the battery is fully charged? Have you tried resetting the alarm, lock and umlock the door 3 times slowly with the door closed then see what happens.

 

1999 Disco 11. ried the alerm reset. When the key is turned in the door, nothing happens at all. have tried it several times in everyway possible. tested battery, alt and all connections, all good. Does anyone know if there is a fuse or alarm relay? When I push the door unluok/lock button on the dash, absolutely nothing happens. Thanks for you help.

 

There is a fuse block under the drivers dash and under the hood.

 

well it sounds like your alarm is working just not disarming (so finding a fuse wont help), the alarm system in a d2 (I am guessing that's what you meant when you put disco 11) will only disarm with unlock, according to my tech sheet the unlock trigger requires 2 negative pulses on the blue/gray wire located at the BCU in a 22 pin plug, at pin 22. the BCU is under the passenger side dash. If I was working on your vehicle I would try to find that wire and (with a 5 amp fused jumper) tap that wire to ground quickly twice and see if this helps to fix your problem, that is the best info I can give you.

if you need more help or a better explanation ask and I will try to provide it.

 

Chris, THANKS! This solved my problem. All working fine now. Thanks for your help and everyone else who offered advice. It was much appreciated.
