Although, the subject of 'Bump-Keying', also known as the '999 Method' is often presented as a cutting-edge cylinder manipulation technique and has recently surfaced as 'breaking news', the practice has been familiar to Mul-T-Lock and the locksmith industry for many, many years now. Many present the method as an undetectable and simple way to bypass high security; this, however, is not the case, and Mul-T-Lock's high security cylinders are prepared to resist this type of attack. Keep in mind that the conditions under which people have claimed successful 'Bump-Keying' attempts are often within the confines of a controlled environment: a laboratory experiment if you will. Out in the real world, however, thieves and criminals are subjected to time constraints, discreet behavior, and other relevant factors. Those who dedicate hours upon hours and even days upon days to uninterrupted, diligent, manipulation attempts simply do not represent the actual conditions of a cylinder's use. Furthermore, those that claim to have the ability to defeat our locks have often been found to be using pre-treated (altered in advance) cylinders that are designed to trick the naked eye, much like an amateur magician's 'special' deck of cards. Our high security products are designed to defend against a vast array of manipulation techniques on real world applications, and we confidently assert that unauthorized entry will not be gained by anyone under such conditions. Proof of this is in the fact that not one supposedly successful bumping attempt was performed with a non-treated Mul-T-Lock cylinder straight from the shelf of our factory and onto a customer's door.
As a top global player in the high security arena, Mul-T-Lock has enjoyed the benefits of having access to worldwide information on security threats long before they are introduced to the mainstream. This defense has allowed us to arm our products accordingly right from the very start. In addition to exceeding an amazing range of international strength and reliability standards, Mul-T-Lock has continued to combat security risks through constant research and development as well as product testing and evolution. We have long integrated strategically placed hardened steel inserts throughout our robust and durable cylinders to gain a UL 437 listing for drill resistance and have surpassed many international standards like CEN, VDS, and SKJ, to name a few. And since we are no stranger to the existence of 'Bump-Keying', Mul-T-Lock has been incorporating 'Mushroom Pins' and combined inter-locking pin sets into our entire product line. The design of these sets and 'Mushroom Pins' has proven particularly effective in preventing the 'Bump-Keying' cylinder manipulation method, and has added yet another powerful element to our impressive list of mechanical precautions.
Mul-T-Lock is always on the lookout for new threats, and staying a step ahead of the game is what we do best. You can be sure that being protected by Mul-T-Lock means being protected by a company that incorporates global experience and worldwide know-how into each and every product.
