Oops, the price went up a bit since I bought these a few months ago, still a good inexpensive option.

 

I actually upgraded my FOB on my ‘10 with a flip key / fob combo. I had to have a locksmith hand cut my key. And I then programmed that fob and key myself. It’s easy. A 9 year old could do it.

 

Very likely the key has gone crapola, if you need to be cheap then adding an additional fob as posted above will work if you do it right.

You can pick up a new, like key, on amazon for maybe 25, or a real one for around 70.

I don't think you can find a new real key anywhere near that. My stored ebay link is now $140. That link is a refurb, which may be exactly what someone wants.
