We run 2014-2016 Silverados at work. I've had several ignition and body locks replaced over the years. The little mechanic shop/gas station that does all our work is able to key the locks to the truck's key, or their lock smith is able to. I'd say you have the wrong guy working for you.does anyone actually re-key locks anymore ? We have 3x Fjords at work. Local locksmith ( probably 30 ) said they can't do it. His dad was great but passed a couple years ago and his son took over. Other locksmith said they can re-key the ignition to match the key but not the doors
Been broken in to a couple times so we have multiple keys for each vehicle now ( doors don't match ignition ).
At home I have 1 key for the house, shed, side and back door. Same at work I have it keyed same front and back doors. Would love to use 1 key to open doors and ignition on all 3 trucks
