RX8Club.com - S1 RX-8 Immobilizer Issue?

Hi guys,

I'm a new member, however I have been reading the forum for while as a guest.

I have searched the forum for other issues similar to mine, however, none are exactly the same as the issue I am experiencing.

I have an 06 RX-8 that seems to have suddenly contracted an electrical problem. I parked it last night after a drive and all seemed fine. The next morning I go out and push the unlock button on my key and noticed the sidelights didn't blink to tell me it was unlocked.

I sat in the car and closed the door, put the key in the ignition and turned it to 'ON'. From here, the Immobilizer light flashes very fast, and I can hear clicking from the engine bay fuse box. None of the centre console is working, the headlights, dipped lights, or brake lights are not working.

If I try and use any other source of power, e.g push the brake pedal to activate the brake lights (which aren't lighting anyway) , I can see the dash dim even lower.

The needles seem to fly around everywhere!

When I activate the lock button on the key, the door locks lock, but when I try and unlock button on the key, the locks only move a couple of mm or so. I can hear maybe a sound of a relay in each side of the car in the doors.

There is also a loud 'buzz' that you can hear in the video occasionally when I push 'Lock' on the key. This noise is coming from the drivers side, just by my right foot. Which is where the alarm/immobilizer is right?

I have visually checked the fuses and think they are okay. The relays clicking is a good sign they are working right?

Could this really be, just a dead battery miraculously overnight? a dead key battery? Or something more serious?

I have uploaded a video so you can get an exact idea as to what is happening.

I only turn the key to 'ON' and not 'START', nothing happens if I turn to start of course.

Link to video.

Thanks,

Matt
