HELP! I need a new key

I guess I'm not helpful and want to know as well.
I bought a housing on eBay and swapped out the internals. There's a vid on youtube that shows how to do it

Hopefully you don't get bored reading about the circuit boards.
Dealers do not have the ability to program these as it's done by the factory so you can't buy one and get them to program it. The black key internals do not fit the chrome key so the best bet would be to replace the housing with the same one or buy a new key. Unless you are good with soldering tiny circuit boards

Hello,
The metal key does not need to be cut to fit, but it does need to the correct blade key. If you don't have a cut blade key to your vehicle you can't lock your trunk in valet mode lock your glove box or enter the vehicle in the event your battery dies in the key. So I would recommend getting the proper blade for your key. One thing to keep in mind is that the non-cut keys could be after-market and like anything after-market there is no guarantee of proper fitment.

AtlasMG, if you read the thread I linked you'll understand this all much better.
