I just went through this to get a couple spare keys for my 08 which only came with one key.
I learned a few things. First, you shouldn’t need to spend much money at all. More on this below.
The keys for our vehicles are transponder or chip keys. There is a four letter code for the chip you need. Search eBay for replacement keys for your year. It may be the same as my 08 or may not. My transponder key code is 4D67.
The other essential piece of info you need is the FCC ID from the fob. This is a 8 character code. For mine it was stamped on my factory remote. But a search will also likely yield the FCC code that works with your year. My code is HYQ12BAN.
So if you’re getting a key and remote or remote integrated into a key, you need to pay attention to both. Obviously, if only ordering one or the other you just need to pay attention to the one that matters.
Now once you get it, there are videos and instructions online that allow you to program the key and fob yourself. No special tools are required. For the key, you need a working key and your new key and the instructions. For the FOB you need a working key and your fob. The instructions are fairly bizarre (like open and close the door several times) but it all works.
I programmed my blank key and remote myself as mentioned above and then took the key to Hone Depot and asked him to cut it. He didn’t charge me as they normally only charge you if they provide the blank.
Key and remote off EBay cost $15. Programming myself for free. Key cut by Home Depot for free. Can’t be easier if you have the right codes.
I got this nice folding key… even though it’s for a different vehicle with a remote hatch, the key and fob codes matched which is the important part.
