I just did some more research the 4 button remote for $66 also comes with the module.

So if you wanted to save $ on new remotes; you could buy 1 3 button w/module for $46 and 1 4 button on Ebay for $14. Total $60 saving a bundle of bucks. My local Chevy dealer wants $102 each for programming fobs.

 

Has anyone here actually used one of the Napa programming modules?

 

I have not, I just found it in the catalog by accident. The fobs are not GM, so I can't be sure that the 2 circuit boards are identical, the GM ones are.

The module sends a "learn" command to the car, then the fob interacts with the car. So, I don't see why it would not work universally.

I could not make out the logo on the catalog pics, but It may have been similar to Viper. NAPA only sells them somebody else makes and distributes them. They surely must be available from other sources as well.
