Hi guys

I have looked using the search but cannot found the answer!

So last night I went to drive the car for first time in couple of weeks. Car has a month old battery
Remote would not work and so had to open with key
Tried to start the car but would only crank
So then went to change batteries in the fob. Still no joy
Then realised it was probably a fuse - turned out fuse in the boot which controls central locking, infra red etc.
Changed the fuse and then the key would unlock and lock the car
BUT
on trying the start the car, the red and green lights in the mirror flash (not simultaneously) as if immobiliser is on.locking and unlocking does not help

Since then I have
- left battery unconnected for 30 mins to try and clear things
- tried to sync key - point at rear mirror and click twice - then turn on to ignition without trying to start car - nothing
- spare key is the same
- tried locking and unlocking with key again
- tried passing remote whilst it is in ignition

Nothing is working!! Any ideas? Battery in remote was out for literally seconds whilst I changed them

Not sure if problem is down to changing batteries in remote or down to something I did before changing fuse ( unlocking car wt key etc)

Can't get car to as it won't move!

Help!!

First do this.
Turn the headlights ON.
CK the battery voltage.

I suspect that your brand new battery is discharged.
Disconnect the polls and then charge it.

I've fixed it!
I stole the replacement 8amp fuse for the central locking from the radio fuse as I did not have any spare. This was my mistake
Replaced all fuses and the car roared into life
Can't think why radio fuse would make a difference but we live and learn!

Looks like that fuse also controls the ATA/ alarm system....

Glad that you got it. :)
