04 Lx470 - "secuity Light" Comes On

[mgz502]

Hello all - everything appears to be normal until the car is started and while driving. This happens with both master keys. The light will stop blinking when the keys are in ignition. Again, everything works as "usual" with exception of this light. Any ideas?

Thanks - Randy

Have you just added keys or ECM ?

Key learning is still open , it can be closed by using a Lexus techstream.

Thank you James! Oddly, we have not been adding anything or making any mods. The light went out this afternoon when we drove it. Maybe some theft was trying to steal our car the night before.
