So, my 07 RX8 has the keyless entry flat card key deal, and the card key is totally dead- no remote, no transmitting, nothing. I've been having to get in, lock, and start it with only the physical backup key.

I just got it back from the dealership, where I thought it'd be covered by warranty. It isn't, and they want $385 to fix it. That's way too much, and I know that almost anything the dealers do I can do for cheaper.

So, can I get my own new card key and program it? I know it's possible for normal fobs, and I hope it is for this too. I also have a normal fob from my old RX8, could that be adapted for use with the keyless system to function like a normal start? If anyone knows, please help me out. Thanks!

 

Search the forum for "FOB Key Programming". Unfortunately, to re-program or program a FOB switch-blade or flat card key, you will need two working keys(vallet key counts). Otherwise, you'll have to purchase it from the dealer.

 

Well that's a problem. Any known way around that?

 

So, you only have one key that had the non working FOB? You would have to order it from the dealer... Try reading the DIY: Key FOB and post your concern. A lot of other owners have switched from the '04 key FOB to the switch blade type. They may offer some advice if you only have one working key.
