I've got to thank Jessica, our office manager for letting me know about this life hack.

If you have a Ford, Lincoln, or Mercury (I've never actually tried it on Lincolns or Mercuries, but I've been told it works)  with the door code panel, you can use it to easily re-lock the vehicle.

Being honest, when I first got my Ford Edge, I never thought I'd use this door code.  I was wrong.  I use it all the time!  Mainly because I am lazy...
