I've seen a few unsuccessful DIY attempts at this - is there a way to get an S2000 (MY05) key with integrated keyless buttons like the Accord and Odyssey? It's a big hassle to carry around the big S2K key, the cheap looking keyless fob and the too-large and cheap looking Lojack early warning fob. A thread from a couple years ago claims that it can't be done - is this still true?

Do any of the lojack keyless entry fobs include the early warning chip? The lockjack fobs all look like they're for their alarm systems and you have to still carry the early warning fob. I don't mind having one fob, but two plus the big key is a big pain in the a$$
