I tried for my Ford Edge, but No-Go.
You need the chipped key to turn the ignition switch full on to move it from Park to Neutral. Once in Neutral the key can't be removed for you to switch to the unchipped key. You could do the same thing with an unchipped key, but once in the full on position without the chip it will disable your car. My key can only be removed in Park & the full off position.
I never liked leaving the key in, but to keep the steering unlocked it's the only way to travel. I've asked several service techs at Ford about removing the steering locking pin so I could travel without using the key, but it's part of the computer system and can't be removed or disabled (per Ford).
I'm learning to live with it, but don't like it. I hope I never need to use the Low-Jack.
