We made our name with Bump Keys - I personally invented the Dampener method and we're still the only retailer who completely removes the shoulders from our Bump Keys to make sure the technique works perfectly.
Our bump keys are also patterns specific. Meaning we tested, tested, and tested again, working out which of the many different patterns works best for what locks and applied that cut to the relevant profiles.
Our universal sets also have multiple patterns cut onto the same profile (and the reverse version of that profile) meaning you have multiple chances at a successful bumping with different patterns that engage differently with the pins.
To have made changes to the age old Bump Key, to have brought it up to date to deal with modern locks, and to have been imitated all around the world is testament to the quality, innovation, and success of our expertly designed keys.
