Unless you disconnect the battery in the FOB, it will not lose its memory.
Taking the fob battery out will not lose anything. The moment you put the fob battery back in, all is well, and no memory needs to be reset.
Train a new fob, remove the battery and tape it to the outside of the fob (so the car won't 'see' the spare fob), and hide it inside the car for emergency use. Keep a spare key (with the plastic cut off) in your wallet.

Problem solved!
Why not leave battery in and put a piece of plastic between contact and battery, put rubber band around FOB. Store in small plastic bag and hide. To use: pull plastic out and hold together with rubber band for temporary use or snap shut for permanment use.
Why do you need to hide a key. Have a new key made. Grind off the black plastic end and put it in a wallet key sleve and in your wallet. That way it is always with you.
Better yet, why not just keep a spare FOB battery in the glove box or console? That together with the key you normally carry you're covered.
The purpose of removing the battery is not to preserve the battery's life... it is so that the car doesn't 'see' the 'emergency' fob that you've hidden in the car, and allow starting or unlocking 24/7, whether you are there or not.

.......and if your wallet is lost or stolen whoever finds it will have your address from your driver's license and know exactly where they can find your car........., and simply drive it away. Oh..., that's right, you keep it in a garage all the time....., well then they'll follow you to work or dinner or wherever some day and drive off when you least expect it. Keep a spare key in your pocket....., not in your wallet nor on the car.

Can't you see yourself in the dark of nite fumbling in dark to put the battery in FOB and hoping you don't drop it on the ground. There is a better way! What happens if you lose that key you are carrying in the mountains for example. What would happen if you lost it all or it was stolen out of your pocket. What would do if your locker was broken into and your pants are stolen. Think about it!
they got a new copy of a key that was all metal, no plastic. drilled out hole so that a license plate bolt would fit through it, cut the slot in the bolt a bit wider to accept a nickel or quarter and then put the key behind the license plate.
then if you're ever stuck just find some change and unscrew it.
If you are parked at the start of a hiking trail and you lose your FOB and you are the only one there, where do you find change or a screwdriver? Can I call you for help?
I thought the keys had a programmed chip in them in the black plastic area. You sure you can grind something like that?
The physical (metal) C6 key _cannot_ be used for starting the car -- its *only* purpose is to emergency open the trunk, and to lock/unlock the glove box, so it does not have the security chip in the plastic head that some other GM cars do.
You can start and drive the car and leave the metal key at home (or not even have one at all), so what would the purpose of a chip be in this case, right?
I've cut off a few myself... there's nothing in there.
