i didn't realise that there was the emergency key hole to unlock the car until looking through the manual more carefully - it's very well hidden and makes the car looks a lot sleeker without a metallic keyhole to spoil the lines
perhaps if you are doing it at night it might be useful to carry a torch on your keyring or something.
remember the days when the key used to have an integrated light? my dad's old BMW used to have this - obviously in those days remote locking was not a feature that had been invented yet and having the little torch helps find the keyhole. i kind of miss having the torch.
i heard of a van that features a key that charges the little battery whilst it's in the ignition slot whilst you drive - can't remember which one, it was featured on a Top Gear segment. considering all the little luxury features the GTI comes with, i'm a tiny bit surprised this wasn't included with the GTI.
