I use a snap punch and all but one has come out over the years........so I used a regular punch on that one.
I was at a party and some girl asked me to give her a ride home while claiming to love Z cars.
Some wannabe suitor decided to hide my keys in an attempt to give her a ride home himself but I had a snap punch in the center console and further impressed her when I stripped the column cladding, quickly took off the lock, and drove off with her.
Once the snap off bolts are out, you remove the switch from the back of the lock and use a screwdriver to start the car.
