Bumping is one of the ways of opening your lock when you lose your house keys. While the technique saves you a lot of trouble when you lose your keys, you can’t bump all types of locks. Are you wondering which are these units that you can’t bump? Here they are:

Key-Controlled Deadbolts

There are some manufacturers of high security deadbolt locks who manage the keys, or key blanks for their units using a controlled system that eliminates unauthorized duplication of keys. This means that you can’t bump the units. For you to have access to the key blanks you need to be either the manufacturer or an authorized dealer.

Multiple Locking Technologies

Does your lock use multiple locking technologies? If the lock makes use of the technology chances are that it’s resistant to bumping. Locks with the technique tend to feature a sidebar mechanism that is combined with secondary locking mechanisms.

Some lock models have a secondary mechanism that consists of a special elevating and rotating pin tumbler design that is coupled with false slots on the bottom pins and mushroom top pins.

In other designs, the dual sidebar lock is combined with a large number of bottom pins and a patented U-shaped key that has a trigger mechanism which makes the lock bump proof.

Side-Locking Bar

These locks make use of a side-locking bar instead of the traditional pin-and-tumbler system. The cool thing with locks made using this way is that they can’t be bumped.

You should note that some manufacturers make deadbolts with a side locking bar in addition to pin and tumblers. If your lock is made this way you should be very careful as the people can easily bypass the side-locking bar and bump the lock. To be on the safe side always g for a side-locking bar that doesn’t make use of the pin-and-tumbler system.

Sliders and Disk

These are deadbolts that have disks that operate the same way the safe dial do. There are other deadbolts that make use of a system of sliders that come with one slider for each key cut. The cool thing with these sliders is that they don’t create a vertical shear inside the lock which makes them impossible to bump.

Conclusion

These are some of the door locks that can’t be bumped thus ensuring that you are safe. To be certain that no one can bump your lock, you should ensure that you buy your lock from a reputable store.
