I have a 2007 Focus that I pull behind my motor home and when I get ready to tow it, I have to turn the key to the "on" position to unlock the front wheel so they will follow. I have twice run down the battery when towing

and I am wondering if there is any easy way to "defeat" the automatic locking of the wheels when the key is in the "off" position. I know this is there to deter a thief (if they want it they get it anyway) but, I am willing to take that chance. Any help would be appreciated. And if it can be done by a novice such as myself, details of how to proceed would be appreciated
