That would probably bump the price up though, giving the battery a Lithium Ion battery or a NiMh battery would jack the key price up $50 bucks or so, and then you have to put a charger in the car...it would probably raise the car price $200 for OEM niceness. Not to mention having to worry about keeping the contacts on the key clean so the metals can touch well to charge the battery...
Don't forget about the 20-25k+ bill someone will have to pay when they forget to take their key out of this charger. 1) doors won't lock and 2) the car is ripe for a joyride to the chop shop.
And a big lol about the holder being a charger... it's not a cell phone or a laptop, it's a key fob. Designing something to be rechargeable when you would only need to change they battery once every few years doesn't make any fiscal sense. Plus, rechargeable batteries are always discharging, so in 2 years you would be charging it a lot more than replacing the battery once or twice.
