Hey Charles how are you

you will need a factory scanner or equivalent to run a diagnostic scan and retrieve the fault codes .

1- do you one or 2 keys and have you tried the other one

2- have you tried wiggling the steering wheel while you trying to unlock with key

But for now you can try Manual Reset

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )You can use any electrical wire as an extension if battery cables don't reach

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You
