Out of curiosity, I tried the emergency key on my last car. Yes, it works - it unlocks the passenger door.
The transponder chip in the card is a passive device anyway - it's energised by the chip reader in the card slot, and so doesn't need a battery to work.
The emergency key is really there in case either the card battery or car battery completely dies. In both cases, you can't get into the car using the remote because the central locking won't function. That's when you'll need the key.
Of course, if like me, you park your car with the passenger side hard up against a wall, building or other object, then you're stuffed. They really should have moved the key slot onto the driver's door for the RHD models.
