If you have a second fob try to start with it first.
Many of these vehicles will require of scanning the vehicle for the security codes and fix accordingly.
But try this first: Disconnect the battery for 10 minutes. Reconnect, lock all doors and unlock with the key fob.
Try to start the vehicle. (If you 2 fobs try both)
If you still get no start and the security light still on and blinking, the system is refusing the key, possibly a malfunction within the system.
You will need a mobile lock smith to check the malfunction codes in the security system then if possible reprogram your key.
Typically reprogramming the fob will fix the issue.
Let me know what you find.
Thanks.
