I took in my truck last year to get a BCM programmed at my local Chevy dealer. My module was fine, but I had read somewhere if you got a salvage BCM and matching Receiver for keyless entry you could have them program the module to get this feature. I was told by the dealer head service manager that programming is done with VIN number so the memory is re-flashed on the module per manufacture build specs. I told him to do it anyway and well 300 bucks later no keyless entry. Now I have to go the 3rd party route.​​ And yes the module did not allow me to start the vehicle by just swapping it out, had to let the dealer install it and program.
