I havent really but im thinking of it just to see if it works. I might get a spare and see what happens once i file it down, if its that simple i might advertise as a locksmith and take the easy jobs (bump-key jobs). have you seen the key cutter in B&Q, you put your key in and away you go for under £4. might save me the embaressment of going into timpsons for a duplicate. What do you reckon?
Doesn't the bump key require the correct key blank for the type of lock?
With full depth notches and extended insertion, through metal removal at the key 'end stop'.
We need to either buy better locks or for the 'hell of doing it' modify our own locks.
Add metal, plate perhaps, to the lock barrel front face, remove that amount of metal from our normal key 'end stop' - lock is now unique, and a bump key based upon the standard key will have the wrong relationship twixt end stop and serration cuts -- job done - not easy but not too difficult... On paper anyway
