Recently purchased and fitted 4 aftermarket tpms sensors for 2014 Insignia that were precoded for it. Have tried all advice and methods on trying to pair them but still nothing and error screen. I upgraded my wheels from 18in to 20in. My only other option is using a reset tool but for the life of me I cannot find a relearn screen or mode on my car, any help would be appreciated, thanks.
