Is anyone aware of any key fob alternatives offered by either Toyota or 3rd parties, something like their Smartkey Watch for Crown cars? It is my understanding that this watch cannot be made to work with the Prius, so I assume it will also not work with the Camry. Please correct me if I am wrong.

I don't wear a watch, so this particular item does not actually interest me, but if they came out with something like a RFID door card you could carry in your wallet, I would be interested.

I currently carry a USB Flash Drive, Toyota key fob & RSA fob on my keyring. I only have 3 actual keys on my keyring, but it is a pocketful because of this other stuff...

 

There is a smart key watch for the Camry in Japan.

There's also a wallet-sized SKS card available through your local Lexus dealership. It's Cdn$200ish and is the size of a credit card.
