*Bump Keys are ON SALE*
Bumping a Defiant lock
Posted 04 May 2009 - 10:51 AM
However, I bought a brand new Defiant brand lock for an office way, and after reading your post thought I'd give it a try. After nearly a solid hour of attempts, I did not have one successful bump! I took the same key back down to my back kwikset type knob and got it 4 times in a row. (??)
So- I studied the key for the much older doorknobs that my bump keys work on, (some of these knobs go back to the early/mid 80's) versus the brand new Defiant key that it does not work on, and came to the conclusion that the defiant key had much wider flat spots that the pins rest on. Look at the attached sketch of defiant type key teeth.. Not having a flat file that small, I actually purchased a KW1 bump key here and tried it out, unfortunately it yielded the same results as my home made keys.
Now I'm very curious about this. Has anyone had marked or consistent success bumping a Home Depot line of Defiant brand locks? ??
If so- what's the trick?
this one lock has me feeling like a newbie all over again.

Yes you are right, this type of lock is harder than kwikset to bump, I even tried may times but success is not always there. practicing on this type of lock need patience.
I also ran into this problem with a defiant when i knew that it was the same as a kwikset. I did finally bump it but it was much harder too bump. Im thinking it may have just had something to do with the wear on the pins and key versus the wear of the older lock. Like i said I did finally get it but with much less of a sucess rate.
