I have a weird scenario. I bought a '99 Ford F-150 SuperCab at a Chevy dealership. The alarm installed is a GM product. FCC ID: EZSOEMTX
I took my truck to a carwash and one of the employees there messed with the configuration so the alarm wouldn't keep going off. He wasn't able to change the settings back to it's original configuration and I have misplaced my owner's manual. Any suggestions or tips....??
