I didn't get the fob for the keyless lock either. But, I did get two full bottles of propane, a so-so Interstate battery, gas in both tanks and two bottles of blue toilet juice.
RVLOCK.com is an outstanding place for parts. My keypad membrane started cracking so I called to see if they could fix me up with a new membrane. They did better than that, shipped me a new lock (with battery), for free.
