The unique dual sidebar locking system makes the lock effectively pick proof. A well-known lock picking expert in England has made a pick for this lock, however, we have been informed that you “pretty much have to have a working key in hand to make it work”. Of course, if you have a working key in hand, you really don’t need to pick the lock.
Unauthorized key duplication is the single most important security consideration of any lock. It is estimated that over 40% of illegal entries result from unauthorized key duplication. If someone can get a copy of your key made locally (or online), you have lost control of your security. And worst of all, you may never know it has been done.
The unique double bladed key cannot be duplicated on standard key duplicating equipment. In fact the key cannot be duplicated at all, it has to be cut as an original key each time and then assembled into the finished key. This requires two machines, available only to Authorized BiLock Dealers. An Authorized BiLock Dealer will not copy BiLock keys made by another Authorized Dealer and will only make keys for previously authorized individuals from a list that YOU provide. The COPY PROOF KEY design prevents unauthorized key duplication ensuring that the keys you give out are THE ONLY KEYS THAT WILL WORK YOUR LOCKS.
Lock bumping is a form of lock picking that has been known to locksmiths for several decades. Bumping involves using any key that will enter your lock face and using it to open any lock combination. The key is cut to a special code that will allow it to open any lock ever sold with that profile. These keys are readily available on the Internet. The holder of the key will put the key in the lock, then bump the tumblers and with the correct timing can turn the lock to the open position. There is no drilling or loud banging required. Just a simple tap and a quick turn and they are in. Bumping takes advantage of the split pin tumbler by causing the top and bottom halves of the tumbler to separate. When all the tumblers have separated you can turn the key to unlock or lock the lock. Any lock with split pin tumblers is susceptible to bumping. That includes about 99% of the locks ever used on a door.
BiLock uses a one piece tumbler. The tumbler will not separate and is therefore BUMP PROOF.
