Without alarms there isn't a car I can't get into, it's a skill I learned from working in garages and it has proven helpful on more than one occasion.
I once got a free supper for me and some mates by breaking into a Mercedes for a snackbar owner who had left his keys in the car and locked them in there. My favourite time has to be when I did it right in front of a policeman .
A woman had gotten out to pop into a shop on a hot hot day and left her child in a proper seat in the back , when she came back 5 minutes later she realised she was locked out. My brother was passing by and came to get me, when I got there the police had arrived so I decided to just wait.
The cop had a bag of keys which he started to try,there were maybe a couple of hundred keys (WTF?) and I could see the woman and the kid were distressed so I asked if I could try. I had the door on the opposite side to the cop open in 20 seconds, I could see him watching me closely and I could see his mind working. I am not always a law abiding citizen (ex car thief) so I wanted to get out of there ASAP before the cop had chance to start asking too many questions. The woman was trying to get my attention to say thank you , the crowd that had gathered all wanted to know how I did it , the cop was looking at me going through his mental mugshots and all I wanted was to be at home sparkin' a big fat spliff.
