Fly by night Redneck Locksmith!
Ok I am a redneck, but I don't do this dumb shit. At some point in time some idiot rekeyed my customers locks, I go to rekey them and see that on these 5 pin KW1 locks, that each key has the tip cut off, so that one portion that holds pin #5 on each key is stuck in the lock, so the customers keys are slanted on the ends and are now 4 pin KW1 keys, it seems that this guy was selling the idea that if you done this for your customers, it made the locks bump proof and he also said pick proof! Hmm, if this would really work, don't you think it would have been thought of by now?
I have been in the souls of many women, but I always end up on the soles of there shoes.
