I have to start with beginning work with me here a little it's a little bit of a story. I've been contemplating for a while on a different key something that feels a little nicer then the plastic box key.
I looked into programming different keys with the same frequency looking at haa style keys and whatnot.
Had a Porsche Chyanne key with my blade in it a while back for a little while never was able to program the buttons.
Then one day I found out about the Bentley key fobs and was surprised to find at least one person that retrofitted to his VW Phaeton am I spelling that right?
After that I was pretty set on trying to get one seamed to be a very nice key.
And from there set out to find my own after figuring out about how similar they are to the a4 key.
Ended up getting my hands on one from someone local to me for 80$ little more then I wanted to spend but when I look everywhere else and people want 300-500 for a key and some not even good condition.
Oh and it feels nice has a nice click.
Lucky the one I picked up was in good condition.
So now I got the key and after figuring out I will be using a b7 key chip very similar in shape. I found one on eBay for 15$
After I got one I ened up messing up the chip from heating up too much with the solider iron
Was lucky enough to get another! One for 15$ from eBay again.
So now I had a better game plan I had ordered some pogo push contact pins
And had a plan
I have very limited pics because I didn't snap everything of the process I did. It was a lot of being patient and tedious.
So here's one of the inside pics of the guts
As you can see I trimmed the chip with the key to have it fit. trimmed the key housing so the board could sit lower as the panic button was not going to line up if it didn't sink into the housing more.
Now the buttons weren't going to line up exactly either the lock and tunk button on the key housing was missing the buttons on the key chip.
As you see to accommodate this I cut a guitar pic and put it in place to act as a sort of hinge to press buttons.
I don't have any pics of the rfid chip
I just used silicone gasket maker to hold it in place below the board.
I wish I took more pics but I don't really want to take apart again.
There's more modifications I did to get the positive and ground of the battery to work as well. With some use of a pogo push pin and a small stainless spring, And some epoxy
But it is finished and all I need now is to install the ccm, so I can use a b7 fob and will all work
Here's video of the finished product.
