BEWARE!!! YaleAccess and its associated lock are a HUGE security risk!!! Case in point: After receiving help from Yale tech support just now, I’ve learned that if someone ever closes the door and shakes the internal wireless module loose (even slightly), the module will lose connectivity. But, that’s the not worst part. Once the module loses connectivity, YaleAccess continues to report the last state the lock was in before it lost connectivity. Today, YaleAccess showed that the door was locked, when it was, in fact, unlocked. This is a HUGE security risk, since the user is led to believe that the door is locked, when it is not. What YaleAccess should do is report that the status is unknown, due to its inability to connect to the wireless module. This is poor design from a company that markets a product meant to provide security to home owners. This is the single worst scenario and one all home owners should be concerned about. I’m surprised Yale continues to sell their locks along with flawed software. YaleAccess and the Yale lock have been out for quite a while now. How this flaw hasn’t been addressed yet is beyond me. Both should be avoided at all cost!! I am trashing this risk of a security solution and will invest in a more secure and reliable one.
