Intermittent no start condition

[Swamper95]

2011 Silverado is having intermittent start issues. During the no start condition, the compass in the instrument cluster shows no direction. Instead, “- -“ is displayed. There is no clicking in the relay under the hood. I can sometimes remove the key to arms length, flip it over, and re-insert it into the ignition. As soon as a direction is displayed, the truck starts. If flipping the key doesn’t work, I can start the truck with the remote start feature. I have had the truck to my local dealer and my local mechanic. I cannot get the condition to occur for them. The computer is not producing any codes. And neither of them have seen this condition. Any help would be appreciated.

Have you tried your other key to see if it does it with that?

I switched keys about 3 months ago and had almost no issues up until a few days ago. Maybe it’s time to switch back.

 

I’ve been told that there is a sensor behind the dash that detects the key, and that this most likely is the issue. But no one give me a specific part name/number for the sensor. Or how to install and reprogram if I find it.

how many keys are on your key chain? saw a post years ago that the extra weight from the key chain can cause the cylinder/key barrel to wear out and make a poor connection to the contacts.

I’ve had the truck for less than a year and only about 6000 of the 87000 miles. My keys consist of the truck key and fob, a shop key and an aluminum carabiner clip.
