RX won't start immobilizer error

My 2007 Lexus RX with a gasoline engine won't start. It's got about 101000 km on it. Sometimes it cranks, sometimes it even starts for like a second and then dies immediately. The error memory has an error stored, something about the immobilizer. I'm thinking it might be the key? I tried the spare key as well, same problem.

A 2007 Lexus RX is experiencing starting issues, with the engine sometimes cranking or starting briefly before dying, accompanied by an immobilizer error. The problem persists even when using a spare key, suggesting a potential issue with key programming. A similar past experience with another vehicle indicated that reprogramming the key resolved the issue, which was confirmed as the solution after visiting a workshop.

Sounds familiar! I had a similar problem with my old Opel Astra a few years back. The engine would just cut out after a second or two. Did you see any lights on the dashboard, like a security light or something?

Yeah, there's a security light flashing on the dash. What did it end up being with your Astra?

With my Astra, it was also the immobilizer. It turned out the key needed to be reprogrammed. Best go to a workshop to get it checked out.

Thanks for the tip! I took it to a local shop, and you were spot on. The key programming was off. They fixed it for 45€. Appreciate the help!
