Why would keyless ignition not work in a multi-storey car park?

Key wasn't recognised. Realise it could be battery issue. But battery was replaced fairly recently and been fine until today.
Put remote key next to marked point, and car started.

Got home, engine restarted straightaway with same key.
Red light shows on key when pressing buttons to unlock car. And car locked, unlocked and restarted again fine later.

Possible signal issue in car park? signal jammed, interference?
Have put spare battery in car just in case!
