Hi RX-ers!
After much deliberation I decided to start to fab my own combined key out of the key and the remote.
First I was worried about toring my key appart but now I know there is nothing to worry about. You can easily cut the key open and remove the immo transponder chip and use it later.
What you need to do is:
1. Use a paper-knife to open up your key. Make a round cut, from metal to metal about 2mm deep. You don't have to worry about cuttig too deep because there is a hard plastic cage inside or the metal body of the key itself.
2. Open the hard plastic casing and remove the transponder chip. Try to pry it out with a small sliced screw driver. It might take time but don't worry the chip is made out of some really hard stuff. You can even cut the plastic around it if neccessary.
3. Cut the metal key to shape to fit in the remote (see pic, where to cut).
4. Heat up the key on a girdle grab with pincers and put between the pair of the two parts of your remote housing. The inner parts (rubber, PCB) have to be removed before this step.
5. Shape the plastic parts with a fine grater and cutter to final shape. Check the fitting of the key inside until the two parts and the key alighn perfectly
6. Glue the key in with some strong stuff like Loctite 454. Be careful to glue the key and one plastic side only:), otherwise you'll have a hard time to change battery in the remote.
7. Put the transponder chip inside the case as shown. Check if car starts fine. If not (red key flickers, no starter) reverse the chip until good. Fix the transponder with one drop of glue.
8. Enjoy rattle free startups and ride with your new key!
I'm quite satisfied with the result. I'll fix the holes later though, but the original grain is hard to reproduce.
Good luck, it's definitely worth a try!
