In the 9-5, if it doesn't work straight away, you need to press one of the buttons at least 5 times to re-sync it.  I'm not sure if it matters which one...

Thanks Will. I thought you had to tell the car in some way, otherwise it wouldn't know to stop telling you to change the battery (as the replacement message was generated by number of uses rather than measurement of battery strength?).

I think the reset message is generated by a count in the fob.  It gets reset when the battery is removed.

Gotcha - thanks Will. When the 1632s arrive from Amazon I'll be in business.
