Low Key Fob Battery Question...

I just went by the dealer for this tonight. Battery replaced and works fine w/comfort access. No reprogramming required. If the battery dies pull the metal key part out and use that to unlock the door manually. Hold the fob near the Start button and the car will turn on. It doesn't charge the battery in the fob- there's a chip or something that the car senses.
