Lock Bumping (04/21/09)-
This is BAD news... the old familiar "cylinder"
lock is OBSOLETE. Time to think about making a change to your
exterior locks.
The example shown by the locksmith is a VERY delicate key prone to
breakage problems and has a very "toothy" edge profile which can snag
and wear through the lining of pockets or purses.
The Swiss tamper-proof keys have a round nose and are perfectly smooth
along the edges. They have a series of varying depth drilled recesses
along their flat side "faces".
Because they are not cut along the edges, they are not
prone to metal fatigue, breaking off or causing abrasion in the
pocket/purse, insert VERY smoothly into the lock either way, will NOT
BUMP and are difficult to duplicate.
