We had something weird happen with our remote lock recently. Back in March, our dealer replaced the Southco lock with an automotive-style remote with only one fob, which I gave to my wife. I programmed the garage door opener in the truck to lock and unlock the trailer door but while here in Creede Colorado for the summer, we found ourselves locked out a couple of times when we knew we hadn't locked the door. We had key with us, so it was all good, except for being puzzling. We finally found that the front gate to the park, which also has a remote, was locking the trailer door. We were inside twice when the door clicked and locked while someone was entering the gate, using the remote to activate. We are more careful now about having a key with s, but problem solved!
