Are the silverado ignition keys supposed tobe able to be removed from the ignition after the truck is started? Mine come out with the truck running

 

no.....

 

Lol give it a try with your truck. When i do it it wont let me lock the doors with the lock on the door bit i can lock it with the clicker.

 

I know for certain that mine wont come out.... your tumbler is probably just worn down

 

Have you tried starting it without the key ?

 

Welcome to owning a gm. I have had that happen before with several chevy/gmc trucks over the years. you need to replace the ignition key cylinder i think that's what it's called. I dont know what it cost or how to do it on a dmax but it was pretty simple on all previous generations
