2011 S: My wife & I have programmed our individual keys to our desired settings. When we travel together we both have our keys in our possession as we each have other keys on our fobs. Of course upon entry we get the notification of two keys present.

So, how do we mask the key not in use? We currently wrap this key in aluminum foil, a real PITA! Any solutions out there?

 

What about pulling the battery?

 

That sounds like a finger breaking procedure.

 

It's super easy... Start sliding the key blade out of the back of the fob, and once it's about half-way out, use the key as a lever and pull up to remove the back cover, and the battery pops right out. The hardest part might be releasing the key blade.
