There are lots of claims by common brands that they are bump proof. Beware - most of these claims are false. Some may offer some bump resistance but are really easy to pick. These locks are sold online, in big box hardware stores or offered by some locksmiths. A real bump proof lock costs $100 or more. If you are spending a lot less you are probably not getting what you expect. If you really want a high security lock on your door choose BiLock.
Key Control 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. High security lock companies do two things to stop this. They get patents on their keys so they can control who makes key blanks and they use restricted distribution so they know who has the blanks and who cut the keys. BiLock does these things.
Pick Proof The BiLock cylinder is pick proof. There are several videos in the internet showing BiLock cylinders being picked. Not a single one has been done with a factory certified cylinder, in public and with witnesses. If you look close most of the videos show the lock picker staring at the actual key while they are picking it. We often donate our locks to lock picking conventions to continually test the quality and reliability. So far we are perfect. The fact is most professional locksmiths know that it just not practical to even try. They will find another means of getting into a facility.
Lock Bumping 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 a virtual master key for any lock that it can fit in. These keys are readily available on the internet. The holder of the key will put the key in the lock, then bump (bounce) 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.
Any lock with pin tumblers is susceptible to bumping. That includes about 90% of the locks ever used on a residential or commercial door throughout North America. Getting just a few bump keys gives someone access to the majority of homes and businesses in the US.
Today BiLock and a disc style lock are the only manufacturers who can claim impossible to bump. We use programmable side bars so everyone gets there very own code. Other manufacturers use side bars that are made by the factory and shared by people in the same city, same block and even next door.
BiLock is bump proof. Other lock companies make claims of bump resistant, bump stopping, harder to bump and even some that are "virtually" bump proof. They are not actually bump proof but are claiming that they may be somewhat harder to bump than before. If you want a deadbolt that is actually bump proof - buy a BiLock Deadbolt. If you are being offered something other than a BiLock, call us and let us tell you how you'll be safer with our technology.
