Ractis immobilizer key programming

Greetings. The symptoms you describe are indeed indicative of an immobilizer malfunction, particularly with the described error memory contents. Does the security light behave as expected during ignition?

The security light flashes rapidly when I try to start the car. Does that confirm the key signal problem?

That flashing security light strongly suggests the key isn't being properly recognized by the immobilizer. The likely cause is indeed incorrect key programming, as you suspected. Given the complexity of modern anti-theft systems and ignition control, I would recommend consulting a qualified workshop equipped to handle Toyota key programming. They possess the diagnostic tools and expertise necessary to resolve this issue effectively.

Thanks for the advice. I had the key reprogrammed at a local shop. Cost me 45€ and now the car starts without any issues.
