batteries albuquerque nm

I am 2 1/2 hours away from my 1996 Ford RV and discovered I left the key turned on.?

I still have time to go back and turn it off (the motor isn’t running) but that means five hours of driving tonight. Besides having the batteries go dead, what other damage will or could happen? The RV is no longer connected to the 120 V supply. If I could get an answer soon, I can still go back. It is 6:12 PM in Albuquerque, NM where I am in a motel room on April 30, 2006.
I won’t be back for 11 days!
My wife turned on the ignition just to check the odometer before we left, and forgot to turn it off! When she couldn’t find her keys, she remembered, but we were in Albuquerque by then. The RV is locked. Perhaps AAA will unlock, turn the key off, and relock.

As long as the temperatures dont go below freezing… No damage will result, other then a dead battery.

Maybe you can call someone near your motorhome to shut it off for you.
