did the exact same thing.. but in portsmouth like 100 or so miles away from home.. and my spare key. spent about an hour on my own walking to b and q to find potential tools to get into it.. after bending the weather strip on the passenger door, and making a slight dent in the car trying to prize the door open i gave up and called AA. bear in my mind i was skint as fuck back then and i was seathing at how stupid id been. keys were staring at me in the ignition. took me about 2 hours before i gave up, AA turn up literally 20 seconds and they were in. funny when i look back at it lol
