My problem is similar to this describe in previous post. My volvo is 440 19TD 1995
My both fobs are with new batteries but both of them doesn't work. I can open the car with the key but I can't desactivate de inmmobiliser with none fob. I guess (but I'm not a speciallist) the fob's code or similar has been erase because the was empty battery too much time.
Now, I have the car stopped in the garage (two floors under ground, so no problem with anntenas or similar. The car has been here last 20 year in operation properly).
¿Any suggestion? I'll appreciate any help because the car and car's engine is 100% well (maybe 99%

Thank you very much in advanced.
