Engine Immobilizer Alert Light

Any thoughts on why this alert light would be activated after having the truck for 6 months? I can't think of anything I've done differently. Can the key somehow become decoded? It still starts the engine. It's a 2014 2x4. Manual info on page 81. Thanks. Dave

 

I thought that the light flashed all of the time when the door was locked and the key was out?

 

Ha! maybe.. But I never noticed it before. We'll see what others might have to say. I found some older posts/threads which seem to indicate that others have had it just pop up out of no where in the past. Thanks Lynd.

 

You may have never noticed... how often do you sit in the cab w/out the key in the ignition?

 

It does.

Well there you go...guess I never paid attention until now. Weird. Thanks guys. - David
