We are aware that an individual has demonstrated how he was capable of manipulating a Yale deadbolt, thereby creating a potential security lapse. We take all such assertions and demonstrations regarding our products extremely seriously. As we all know, no lock/deadbolt is, or could claim to be, completely invulnerable to all forms of attack, especially when a person has the time, skill, and knowledge to do so. As part of our continuous improvement efforts, we have developed a part that adds an additional amount of security to the deadbolt . If you would like to see if your lock may be eligible for this upgrade, please click here.
