Default 1999 Deville. Theft System Problem message

I have a 1999 Deville and it just started displaying the Theft System Problem, Car May Not Restart message. The car is still running as good as ever. There seems to be no real problem but the message is annoying. Is there any way to get the message off the display.

Ignition cylinder most likely on is way out, wires for pellet reader starting to break apart. It worth checking or having checked before it parks you.
It will be OK
