Add a Key Fob to a 2013 Honda Odyssey using AUTEL MK808K-BT

This 2013 Honda Odyssey only had one key fob and a valet key.
This year didn't come with a start button yet. You have to insert the metal key to start the car. This is why it is important to cut the key first (at Ace Hardware for example, $10) so you can program it on the car's computer (immobilizer).
The new key with the electronics inside cost around $25 on eBay.
Make sure you get the right year, make and model. Also match the FCC ID if you know it.
