I've only just come across this thread, and yes, that was an unusual first post to pick this one out from over a month back :S
Sorry to hear about the car mate, seriously gutted for you, I can only imagine how bad it must be. Any news on it? I'm in the area so will keep an eye out for you.
I always have my keys on me, don't know why I just always have done. Keys, wallet and phone always in pocket and I always check they are there without thinking about it really. When I go to bed I take them all out of my pockets and in my bedside cabinet. It's certainly not safe to have them near the door or anywhere downstairs for that matter.
