Lock Bumping – A Danger Or Not?
Ever since lock bumping videos were posted on the Internet demonstrating an easy method a thief
can use to open a lock, members of the
public have been concerned and understandably so.
In case you haven’t seen any of the videos, or read any of the reports,
here is how thieves can bump open a lock, (without giving too much
This method works on locks of the pin tumbler type, the kind of locks where the key turns a cylindrical barrel in the center of the lock.
The thief needs to obtain a key blank of the exact type used for the brand of lock in question and modify it into a bump key, (also known as a 999 key.)

If the locks on your external doors are low quality, low security, you should seriously consider replacing them.
If the locks on your home have recently been fitted then they may already be of the bump resistant type.
If you have Keyless Locks fitted then, by their nature, they cannot be opened by bumping.
Locksmiths have reportedly stated that bumping is not a skill that is as easy to master as the videos posted online imply.
Not only that but bumping a lock is not always a quick operation, sometimes it takes the thief several attempts.
Bumping or ‘rapping’ the 999 key also makes a little noise, and thieves do not like drawing attention to themselves.
Notwithstanding the above, fitting anti-bump locks would be a worthwhile home security precaution.
When it comes to insurance payouts some insurers may be hesitant to pay out to burglary victims who have had locks bumped.
Because lock bumping does not damage either the door or the lock, so
it is difficult to prove that the door was opened by anyone other than
the owner or a key holder.
On the other hand, some insurers offer a discount for homes protected with bump proof locks.
