sorry to hear about the keys but
at the some of the advice givers
1, AA or RAC etc - if your not covered, find a friend who is, i had a mates mini broken into by my AA cover
2, Auto locksmiths
3, Hammer, not brick,
cos with the best will in the world, popping locks can and will damage paint, and as mentioned, you will have deadlocks so wont work anyway
