Review on 20923680 Monitoring Compatible Chevrolet Silverado by Ashton Dahmer

They must be installed in the tire after the tire has been removed, disassembled and installed in place of the original Schrader valve. After remounting a tire on a Chevy, the memory must be erased and reprogrammed in a specific order. Most tire repair companies don't know how to do this. I visited 4 different companies before I found a mechanic who knew what he was doing. These tire pressure sensors (TPM) worked great when programmed correctly.
