Yep. seen that work many many times. Also, almost every chevy pickup from 88-01 can be opened with ANY key on the driver's side. Also, new GMs can be opened by the remote over a cell phone, lol. My dad locked his keys in his truck at work, called my mom, she held the spare remote up to the phone and pushed the button, while my dad held his phone up to the door, and it opened.
Not many people know this, but Fords have a key code. I think they can look it up by the vin#. You can go to a ford dealer and have a new key cut. I used to do it all the time, when I worked for a car rental company.
