I do not have anything for the code.
Unless your customer has the password you will have to have a Yale dealer come in and retrieve it for you.

Fact of the week
According to studies published in the English Journal of Medicine, the impact of daylight savings is revealed by a 24% increase in heart attacks on the Monday following the spring shift forward.
