It's essentially the same thing but with a foldable key. Still blade type.
Again, there are quite a few lollipop style keys on Ebay. From what I have read, you are only interested in the pushbuttons and so can discard the blade on the new key if it has already been cut.
See if you can find a blank version with virgin transponder.
1. Get new blank key cut
2. Use old key along with newly cut key to programme push buttons
3. Swap new buttons onto old key blade (this will give a key with remote central locking and immobiliser chip)
4.
Store newly cut blade with old buttons until you can get the transponder programmed.
Have a search though, all your questions should be answered in several different ways.
