Default service theft deterrent system

Sorry in advance if there is an answer already on this forum - I couldn't find any.
Chevy Impala 2012. There is a 'service theft deterrent system' message. Both keys and both fobs are working fine. I still can start the car with ignition keys. This vehicle doesn't have keyless start option. The fobs are only for opening/closing doors, opening trunk and locating the vehicle in a parking lot. Batteries in the fobs are OK.
Is there way to clear this message without disconnecting the battery?
