My Kaiser is parked on the street here in London, England. The drivers door doesn't lock properly, and anyway, any would-be car thief knows how to hook open the door locks.
A week or two back, I heard the sound of my "musical" car horn for a split second, late at night. So I get out of bed, go downstairs and look through the window. Sure enough, some youth is sitting in the drivers seat fiddling about with wires. He must have momentarily pressed the horn button by mistake. Taking hold of a conveniently positioned ax, I step outside, pull open the car door, and yell "out, ****". The kid gets out and I say "leave". He runs away, and just for show I ran after him a few yards waving the ax over my head and shouting "if I see you near my car again I'll cut your f***ing arms off". He hasn't been back!
This incident made me think of fitting a simple deadlock into the door and door post. You used to be able to buy these things everywhere, but I cannot seem to find them for sale online. See picture. Does anyone know if these are on sale anywhere? I found this pic on some web site about cars and security, and I remember around 20+ years ago when me and my schoolfriends first had cars, a couple of guys buying locks like these, and helping them to fit them. But now I cannot seem to find them on sale anywhere!
