When I removed my engine, battery was dissconnected for more than a month. I had problems with lock alarm, as soon as I connected battery back.
It seemed that alarm doesn't work at first, so I locked doors with that key itself. The next morning everything worked fine. So I think it reprogramed itself somehow....

Thanks Biotoxic. I know about that. The battery on that car is dead anyway, so anytime i need power, I transfer the battery from my good car. The problem is that I removed the battery from the fob.........................

They should be able to do it. Best thing is to give them a call and ask them if they can do it to be 100% sure. When I first made this guide, I assumed that if I changed the key with the matching Immobiliser unit, the immobiliser would work on its own. ANother member told me that the key is programmed into the ECU instead but I never got a chance to test it.

Have you considered how you are going to take your car to the dealers when you put in the new ECU, as your key will not work with the new immobiliser. It is a lot easier to change the ECU by the way. On my guide I made a whole write up of taking the centre console off first etc. There is an easier way by removing the plastic/fabric trim on the side of the drivers footwell and you can access the ECU directly. Here are the VADIS instructions.
You might as well try swapping the ECU and see if the key is working with the immobiliser or not.

Thanks for the reply i have removed the ECU to check the wiring my thought was to get a module from the breakers and tow it to the dealer to get it programmed.
My other option is to send my module for repair but will it still have to be programmed.
Do you know of any module repair people ?
Thanks Col.

No idea to be honest. You are better off with a second hand unit. They hardly ever fail as units, so I guess you were unlucky with yours. I would still try to get one and try it out before you take it to the dealers. Maybe, maybe it may work with no need for programming...

Too much of work, but this is very detailed guid and cant be any better than this

I have changed out all the parts in the original description but my central locking just isn't working. I've checked all fuses, fob batteries etc. The car will not unlock either from the remote or from either of the door switches.
Anyone any ideas on what i could try next?
Am i missing something?

Volvo had a quick look and told me up to 8 hours labour to investigate further. Their initial finding was that the controller wasn't getting a signal

gatos · Jun 7th, 2013, 17:11

Have you checked the bonnet switch? If it is very dirty, it might cause you problems. If not, the next thing to check would be the alarm siren. Ideally, you should have your codes read and it would normally pinpoint the problem. 8 hours to investigate is taking the ****

marty3271 · Jun 7th, 2013, 17:38

I have looked at the bonnet switch, but can't see anything that ties it to the electrics in any way. I'll maybe just remove it and give it a good clean anyway.
Thanks for the advice, i'll let you know how i get on.

PS. I assume the interior lights are connected, they don't come on when the door is opened, only the footwell.
