Never needed unless you lose all the other keys, in which case you'd just need new ECU and locks as well. I've never had one and never needed it and I've had the battery disconnected for long periods before.

A few people have needed their red key when their CODE unit has got a bit confused but it's not really a deal breaker any more as you can get it reset, if the rest of the Coupe is good then don't worry about it.
