You will not have the barcode mention unless you purchase a new remote fob. The remote key you have contains the remote chip and a transponder pill(which is used to start the car). They are useless without each other if you try to start the car so you better be careful with that one key without a replacement.

Your remote key is broken if you changed out the battery and it still doesn't work. It could be an easy fix. I had to solder a new button for mine. Your valet key doesn't have a transponder pill so it's only good for locking/unlocking your doors/armrest/trunk access. If you want to turn that valet key into something more useful then it will cost you about $150-$200 for the new key fob plus a few hundred more to a dealer/shop to program it. You will reuse your valet key that's already been cut.
