Detailing my Chevy and i was playing with the lock rockers and locked myself out the truck.. reached into the window and unlocked it.. truck started honking so i hit the panic button on the FOB, then started the truck. Noticed the DIC Said RFA 2 battery low. Id assume this is for the KEYFOB? My FOB says number one on it.. i removed the battery and Tested it at 3 volts, Still have the message. concerned i zapped something with my recent stereo install. any advice?

 

Wow. Worthless forum. Nobody answers my questions
