Immobilizer stopping the start

My vehicle normally starts when I, after sitting on the driver's seat, twice press the remote button on the key which unlocks the immobilizer of the car, and car gets started. This time after I ran out of fuel, and refueled the car on the road by a cannister using a nozzle, the car did not start, and every time I move the key, the ignition comes with immobilizer light on the panel flashing. The engine does not start. Could anyone help please.

This sounds like you are having a larger issue with the key being recognized. I am not sure it is related to the vehicle running out of fuel or not but if the theft light now flashes and it didn't do this before then we need to start with checking for codes.

Here is a guide that will help with this:

Once we know what codes are in there then we will have a better idea on which way to turn.

However, if there are no codes then we are going to need to try and disconnect the battery and retest. Basically, this will force the modules to reset, and we may be able to get past the theft system.

If not, then we most likely have a key or immobilizer issue which should have some codes to point us in that direction.

Unfortunately, we don't have a manual on this vehicle, so we are going to have to try and figure this out based on the codes that we have.

Let's start with this info and go from there.
