I'm not a member, but will be soon. I have 2015 Silverado and the passenger door lock is having problems opening. It works from the drivers door, but not the remote. I was almost going to order a new lock when I noticed the GM part description "Extended range keyless remote door lock". What caught me was "Extended Range Keyless". With that description, the lock is getting a command from the FOB. I changed the FOB battery works perfect been testing all day. FYI. Steve
