Hello,

It sounds like an issue with the immobilizer system.
So when the immobilizer activated you are unable to start the vehicle. It is a anti-theft protection device.
It could be due to a faulty module. Also it could just need to be reset.

Try this method to reset:
On your key for press the unlock button 3 times.
Then press the panic button once.
Lock and unlock the driver door with your key.
That should reset the system.

Here is a helpful article:

Please let me know of any questions.
Thank you.
