SEREPICK is now offering a Bump Key 3 Pack and Bump Hammer (sold separately). Insert spooky, October-appropriate, “bump in the night” joke here.

The Bump Key 3 Pack includes three of the most common key types in the Kwikset KW1, Master M1, and Schlage SC1. They are all cut from brass key blanks.

If you have every tried bumping a lock, you’ll likely know that it takes some technique but that the right hammer can really help. The hammer offered by SEREPICK is designed to offer the sharp rap needed while reducing the likelihood of damage or marring to the lock.
I’ve always wanted to try them out but our companies locksmith said they were bogus and wouldn’t work. Would like to see some real information on Bump Keys that isn’t YouTube based.
Bumping is definitely not bogus and they do work… however, like every bypass method, they don’t work in every situation and they do take practice. It is surprisingly technique sensitive to get the right sharp rap on the key which is why having a hammer that doesn’t work against you is so helpful.
A set of picks will work every time, as long as you know how to use them. See “The Lock Picking Lawyer” on YouTube. There isn’t a lock he can’t open.
