What country1911 said I just had similar troubles with my remote door locks and starter. It,s all in the passenger door sensor.

Good call country...

The dealer replaced the module that receives the signal from the fobs. I guess it was just coincidence that it happend a day after I installed my gauges. I even made a booboo and forgot to put the stock tune back before I took it in. It was never brought up. They replaced the module and all works fine!!

Just to clarify, you received warranty work with an aftermarket tune?

yup!!!!!!!!!!!!!

Can we sticky this last post

I've noticed that a lot of the issues some of us have pertaining to aftermarket parts has a lot to do with the dealer. The one I work for I would say has to be the worse. The service manager/tech has to determine that the problem was caused by the equipment some are just lazy and they instantly go to the aftermarket parts and some actually do their job. Anyone with anything aftermarket installed should probably look for a dealer that sells the up fitted trucks ie. Rocky Ridge / Southern Comfort... to go to when getting warranty work done. I say this mainly because they are used to looking at modified trucks on a regular basis. I am not saying that they are going to let u get by with a 12" lift and 40's but they may and I use may very loosely be a little less lazy when it comes to finding a problem.

Glad you got it fixed!

Hello,

Im just your friendly GM back yard master here to help you when GM paid mechanics cant. I finally found the culprit for this issue on my 2011 Silverado 2500hd LTZ Duramax. I had the exact same issue, one day i came out and the remote start wasnt working after further inspection neither was my tpms or backup alarms. I checked everything. Replace fob batteries, replaced truck batteries, replaced wireless receiver module, replaced body control module, replace receiver module antenna, cleaned all plugs and put dielectric lubed on them, reflashed each module 4 times. Nothing worked until today. I pulled all the wiring harnesses apart in the drivers door and the drivers side canal going from the dash to the back pillar. After 4 hours of hand over hand every single wire in the canals and door i found two little red with white lines wires twisted around a big red wire, located at the front of the canal of the drivers door at the point where the two harnesses coming from the back come together. These two little red wires where kinked and corroded from moisture in this harness. I cut the wires soldered and heat shrinked them back together. AAAAAANNNDDD BAM my Tech2 could read the modules again. I reprogrammed the fobs after putting new batteries in them. And reprogrammed all the modules again since they have updated in yhe software to fix issues with the back up sensors and the security system. I would include pictures of the wires and their location, if i knew how. i hope this helps someone else who has been chasing the same issue.

Respectfully,
