So today, with the help of my 9 year old we detailed the yukon, inside and out. Got all finished, closed the doors only to realize the keys were now locked inside. I don't have the spare fob, and of course the key doesn't work in the locks anmore, so I had to call roadside assistance and wait an hour. heres my question, and something I've dealt with since we discovered keyless entry...what is a guy to do to prevent this from happening. in the old days I always had a spare key behind the license plate, but that won't work nowadays because the locks always seem to rust up from lack of use. is there any way to rig up a push button switch somewhere that would trigger the doors to unlock? the wifes ford has push-button combination on the door, I love that idea. can something lime that be rigged up or purchased for a vehicle now?
