ya that's the dorman fob & programmer I have sold a bunch of those before. the programmer is only good for 3 uses so be sure to do it correctly the 1st time then you will be to do it again years down the road or something if need be.
Only 3 times? I guess no one has figured out how to defeat that yet.

Truck has been running pretty good, especially with this little bit of cooler weather.
have noticed a bit of cold start exhaust leak, thought it might be the manifold so went by the muffler shop and had them check it and couldn't find much but the clamp from the y-pipe to the muffler leaks a bit it's a pos oem clamp anyway and found the Borla muffler was cracked on the inlet seam, so welded that up and then took it to the dealer to have them check the manifold anyway since they had it off and they did a smoke test and nothing up front but that clamp is leaking pretty good and found another crack in the Borla on the outlet end.
so back to the muffler shop and they welded the other end of the muffler. Asked what a solution is for that pos clamp and we are going to cut the pipe right there and install a set of stainless flanges and a band clamp just had to order one in 3 1/2" so that will get done Friday

6 yrs out of a Borla--not bad.
I didn't expect the cracks that was out of the blue but they were able to weld it, I guess well see how long that last's
been thinking about a carven as it sounds pretty nice on the Silverado but the shop said I would likely get drone in the suv

I had drone with my MBRP, thank God it rotted out. Forced me to get another, quieter muffler. No more drone.<----This statement is how I know I'm getting old lol.
