Hello all, I have a problem here and hope u can help me. i have 05 rx8, bought it used with 1 normal key and 1 switch blade keyless entry remote.
i lost my keyless entry remote and after that i bought one keyless entry remote with un-cut blade from ebay, i programe the switch blade keyless entry remote and its working fine, doors, trunk and panic buttons are working properly. today i took that remote and my simple key which i got with my rx8 to mazda dealer to cut the blade (rx8 is parked in my garage because of snow). after coming back i try to start the car with new cutted blade but nothing, let me explain u in details, i gave the simple key and my newly programmed remote to dealer and he cut the blade.
i can open close the doors with that and when i put new key blade in ignition it turns smoothly and show all lights normal but when i try to crank the enging nothing happend and key light start blinking fast. the bottom line is "new blade doing everything but not cranking the engine"
Any helps?
Thx in advance
