Re: What is this yellow light?
Check the oil at least!
If you have a multimeter, you could check the battery voltage with engine on and off.
It could be bad battery that is causing the lights. Or you could have low oil pressure, a dodgy immobiliser, a bad battery, and an engine sensor or emissions error - but having all at the same time is unlikely!
Is the car running OK? If so, then the key light is odd.
As said above, you will really need to read the faults codes (usually bring to garage).
