Bought my X-Trail ( 2006 2ltr Petrol ) last week ..

When I went to look at it .. the seller unlocked it with the key fob .. I heard the locks clunk open.

Since then , no matter what I try I can't get the keyfob to do anything .. and I only have one.
I've read and read and searched here , utube , google .. and I'm still at a loss ..

Tried replacing the battery in the key ... Nope.

I've heard of some timer unit behind the driver cubby so I thought I'd have a look .. and while I'm handy enough with tools and technically minded I cant see how it comes out and I dont want to break anything ..

My theory was that there may be a bad / dirty / loose connection on the control unit .. and if I do get in there .. are there different versions of the unit .. and will changing one out disable the one key I have which will at least start the car .. for now. ?

Have you reset the key fob after changing the battery. Procedure detailed in the link below.

Hi thanks for the reply ...

Tried that but I think the second line in the instructions indicates that the hazards flash twice.

Nothing happening with mine ..

Ive taken the key apart and made sure all the connectors were clean just in case too ..

Hmmm ...

took the key apart again to check the voltage of the new battery ... it's ok 3.19 volts.

Putting it back together I heard a clunk outside ... and the lights flashed on the car.

Full of new found Joy I skipped along outside only to find that it hasn't worked since ..
I'm beginning to think I may have a cracked circuit board although I cant see it even with a magnifier ..

anyone come across this or do some keys just go flakey like that ?

Try pushing the open button twice in quick succession

Mike

My Xtrail locks with one push of the button but opens with 2 pushes of the open button

Hi Mike ,

Just back home again and tried that ...
However ..I did run through the key pairing procedure that was posted earlier by Milton again.
This time, I got the light flashes at the right time and in the correct sequence .. so thats progress.

The buttons still will neither lock or unlock the car though.. weird

This sounds very much like it could be your time control unit which is a white box under the drivers storage compartment. Please see attached and what its responsible for
