Anti Theft Deterrent System Flashing, Can't start car, help? Anyone?

If anyone stumbles upon this later and needs this info
I had my coil around the out side of the ignition go bad on me with out any reason which made the car not able to read the key so the red light of the car just keep flashing but it will flash a code at you and tell you what is wrong.
Key on position Either it will flash code's listed below or If there are no malfunctions the security light illuminates for approximately 3 seconds and goes out.
DTC Table (Immobilizer System). A verified DTC code will get flashed 10 times repeatedly by the security light. with additional codes being flashed after the first code you make sure you sit there for a min and read them all. It if keeps flashing just one code back to back that's the only one you have
Security light flash pattern:
∩__∩_________ = No detected communication with the coil
∩__∩∩________ = Coil malfunction
∩__∩∩∩_______ = The key ID number data cannot be read or key ID registration error
∩__∩∩∩∩______ = The keyless control module cannot read key ID number data normally
∩__∩∩∩∩∩_____ = The keyless control module has detected unregistered key ID number
∩__∩∩∩∩∩∩____ = Communication error between the keyless control module and the PCM (no response or mismatched conditions)
∩∩__∩_________= Only one key ID number is registered
∩∩__∩∩_______ = Communication error between the keyless control module and the PCM (data transfer error)
∩∩__∩∩∩______ = ID number data in the PCM and the keyless control module do not match.
NOT ILLUMINATED = Keyless control module malfunction

Thanks a lot for the details.

I got that pattern and scanned for codes and got the b2141 No PCM ID stored in RKE.
That happened when I was replacing the rear bumper antenna without removing my battery negative terminal.

Hi I have 05mazda rx8 PZ
Recently my battery died when I connected the cable I connected them wrong way round
And now I have some electric power
Basically at first I was told to check main fuse which was ok....but I still changed it as I ordered one so thort I'd just put it on....I've checked all fuses and relays
The only fuse which had blown was the room fuse which I've replaced
I've even checked the ecu which seems fine
What could it be???
Been told maybe the Immobiliser not letting me start the car???
The only power I have is to all window, headlight, stereo and air conditioning unit works fine....
When I put key in ignition I have no lights on dash apart from flashing key light and door open light ( door was open so this why its on)....I can hear a clicking noise from main fuse box???
So all the gauges have no power and won't turn over....
Any body have same issue ??? Or. An any one suggest anything for me to try or replace ???
Oh yeah when I try to start the car the boot opens???? Which I found very weird

I am experiencing similar issues with a 2006 that has smart key. First smart card stopped working, scan showed that the bumper sensor has to be replaced. Ordered the bumper sensor and followed a post from another member to cut the wires and move the sensor inside the trunk. Followed the procedure, car runs but engine will never crank. Scanned code and it B2141 and P1260 Theft - Vehicle immobilized.
Hi Did you get this problem sloved ???
How did you solve it
I am having the sam issue with one right now

I have the same problem with my rx8 2005 the antitheft system is on
Thanks for all the suggestions, just got back from dealership, they said it flooded... yet it also had the Anti-theft light malfunction.. something about it both happening at the same time when I cranked my car and it tried to start at a higher temperature.
I wonder if adding a turbo timer would resolve the flooding issue... so that it will keep the car running and heated afterwards.

Code error
Thanks a lot for the details.

i have the same problem antitheft system is on can’t start my vehicle. Had to let people come to see if they could get it start or rep program key everything you mention not having communication that’s exactly what scanners reads. Ima check my coils. Thanks for all that info

Did you ever get this resolved? I have a new to me 04 MT that I am intermittently getting this code. Cars runs great other than when I get this code and can't get the car to turn over.

I have the same issue with my car. Doing some work in an area that required removal of the PCM and the PSC - I had to remove the box they were housed in. Now I have an immobilizer light flashing. It flashes at regular intervals with the key off, fairly slowly. With the key on, it flashes faster, but still no code, just a constant flashing. Any help out there??

Mine eneded up being my PCM, I swapped it out and the issue went away.
See this thread for how i fixed. https://www.rx8club.com/new-member-f...-issue-275305/

Turns out, one of the PCM connectors was not fully seated. Now I have a CEL . I'll have to head to my local Auto Zone for a scan. Probably just a result of having the intermittent connection. Hopefully clearing the codes will set it right.
