Towing Issues: towing 2008 Jeep wrangler, 2008 jeep wrangler, jeep wrangler

Question
Just bought 08 Wrangler unlimited to tow behind MH. Due to confusion at Chrysler I only have one key. Now when towing, I need to have the key in the ignition at the acc. position so the wheels will steer when towing. From this position I cannot remove the key and the keyless entry is part of the key. If I want to lock the vehicle during towing, what should I do?

Answer
Well any number of locksmiths can make a copy of the key to fit in the door lock... You do have door locks for when the remote does not work ? correct.. This is usually called a valet key.

Or leave the vehicle unlocked, or roll a window down a bit...

Contact the dealer and get another key  or remote...

There are a whole bunch of answers here but no real question asked..
Sorry for the smart style answer, but its the best I can offer without getting real rude or stupid.
