keyfob

Hi, I lost one of the two key fobs. Any advice on how to program a new key fob if I buy it online? The dealership quoted $85 for key fob plus $350 for programming. I'm a bit confused with the instructions in the manual thanks!

This is the second time this has happened. After a session at a Chargepoint DC station. I lost the ability to start the car by the normal means of the keyfob, having to instead place the keyfob in the console to start. The first time this happened was at a Chargepoint station in Red Bluff, CA...
