No I haven't there are no warning lights on the dash
You don't always get a warning on the dash. This is going to be a difficult fault to solve unless someone who comes across this fred, has seen the problem before. You can buy yer own device to read the codes. I would guess there will be a code generated at the point the car needs to power cycle to start again.
I would guess that the steering lock assembly has an issue. If the steering lock doesn't retract properly, then the ignition won't come on. This condition doesn't always put a warning on the dash either.
I have codes B10A2-00 P125987 immobiliser to powertrain signal error don't know if its key or the immobiliser itself
Have you tried the other fob?
It's sensible to get another fob, as if you loose or damage the only fob, you'll be stuffed.
And to do that it´s quite easy.
