hey guys.. my remote messed up about 2 days ago..
i have a 2004 silver mazda rx8 automatic... sadly =/
i have inspected all fuses, they are all okay.
i put a new battery in the remote, still no luck..
... any ideas on what i should do right now?

 

I have an '04 as well. Both of my OEM keyless entry remote stopped working a year ago. Changed the battery(as you did) and reprogrammed the remotes, but neither worked; however, they both tested OK at AutoZone. If you use the "Search" you will find some posts from other '04 owners who have replaced their remote with a flip-key(bought at eBay) from a later RX-8. It has a different FCC# but worked once it's been programmed. I haven't replaced mine, it became a habit to lock and unlock my car the old way.

 

yeah time to upgrade to switch blade keys

 

Is it that we can not reprogram the old ones once the batteries go bad?

 

thanks for the help guys, im probably going to get the new remote and see how if it works after i program it.

 

I have two FOB keys, both stopped working when their batteries ran out. I tried numerous times reprogramming -followed the procedures step by step with two working car keys- one FOB at a time and it wouldn't. Checked the FOBs at Autozone and it shows that it's emitting a frequency with the new batteries.
