Spare key battery replacement & re-programming?

When I recently bought my MCS (sept 2003 build) the seller gave me both sets of keys and the little plastic emergency key. One remote key fob worked okay, the other didn't work at all and I assumed it was just a completely dead battery. Just changed the battery and still it doesn't work at all.

If the battery has been dead for some time, do you need to reprogramme the key fob once a fresh battery is inserted? If so, how do I do this?
