padlock that uses your car key

[terracore]

Has anybody ever used one of these padlocks in Hawaii? The price is steep for what looks like a cheap lock and I was wondering if they hold up in our weather. The lock "learns" your car key so you don't need to add another key to your ring for locking your gate. Other manufacturers also make ones that do the same with your house key.
