Watch Video - This Chubb Locks bumps with ease.

The full set of 6 of our Ultimate keys. That's 3 left Universal and 3 right Universal, and these locks are EVERYWHERE. There are 3 patterns of each key, cut at different depths to ensure you have the best range of keys for the best possible bumping success. The forum is covered in great reviews for these keys and they are our flagship product - it's where we started and we're still the best at it. This set will open you up to the world of bumping like never before - and that's at LESS - key for key - than getting your house keys copied!
The UK Bump Keys 3 X Ultimate Key set comprises three different keys at the cutting-edge of bump technology today. If imitation is the sincerest form of flattery then these keys should be blushing. Cut in three patterns (Semihexed, 'V's, and Radiused) these keys have been code cut for spacing, and years of bumping experience used to choose depth and 'bump-pattern'. We believe this selection will give you the best possible chance of successfully bumping these difficult to pick locks. Our patterns account for differences in age and wear of lock, tightness or wear of springs etc, the different patterns accommodate this as - like all our 3pc sets - they work with the different conditions of the internal mechanisms of the locks. Pins and springs etc change through time and environmental conditions, different bump patterns get round these distinctions.
Our BUMP KEYS are shoulderless, we pioneered using springs and dampeners which is why our bump keys are still the best in the world. Don't accept cheaper to produce inferior quality products, accept ours, they work!
Ultimate Keys will work on a multitude of locks including Yale, Era, Winkhaus, Zone, ISEO, Mila, Eurolock, WMS, No-name and many more. But don't take our word for it, ask on the forum for 4000+ opinions, you won't be disappointed. We've been trading successfully online for over 7 years, we're trusted and respected.

Our keys are precision cut and as you can see from the pictures below, remain consistent from tip to tip in a variety of our unique perfectly duplicated patterns. All our keys are hand finished, inspected and tested before dispatch, which typically takes a day or two.

You will notice UK Bump Keys don't look like other bump keys. This is because they're not like other bump keys. For a start we take the shoulder clean off, creating the perfect key for 'Bouncing' (or 'Spring-bumping') and using 'Dampeners' (bumping terminology for the use of washers of different materials such as rubber, fibre, or steel, that are placed round the 'neck' of the bump-key to create different 'responses' when bumping). Some vendors will leave the shoulder and tip for you to finish, and supply keys that aren't on the whole suitable for either 'Dampeners' and 'Bouncing'. This is an essential plus with UK Bump Keys as both these technologies have moved the bump technique forward, and � in short � open more locks, quicker.
Our bump keys are SHOULDERLESS, as we correctly developed them some years ago. This makes them function better and also perfect to use in conjunction with springs and dampeners. It is labour intensive to remove the shoulders which is why our competitors tend not to. We also
ensure our bump patterns are the most effective for each particular lock type. We're passionate about our bump keys, buy what works and
accept no imitations.
ALL of our bump keys have had the shoulders removed and are then hand polished so as to make them able to work with dampeners and springs which hugely increases their success rate. Be aware of unprofessional bump keys being sold with the key shoulder still intact. Keys with the shoulder intact are less labour intensive and therefore cheaper to produce, but are NOT AS EFFECTIVE.
