2008 GMC 6.6L 2500HD ignition switch

I just bought a 2008 2500HD 6.6L 4x4. Something is up with the ignition switch. You have move the key around several times before it will turn.

Any ideas on the problem?

It sounds to me that the key may be at fault. If that is the case, then go to a GM dealer with your V.I.N. and they can make a key off that info. Make sure to have just a copy made without the security chip. Try it in the ignition just to see if it turns without trouble. If it does, then you can have another made that will start the vehicle. In the mean time, the first one you can keep in your wallet as a spare to gain entry into your truck!

Sounds like you are having problems with the Ignition Lock cylinder and not the ignition switch. To me it sounds like a tumbler spring let go. You will have to install a new ignition cylinder lock. Or have a locksmith (a good lock smith) fix the one you have. If you install a new the cylinder lock it will come with keys. And those keys won't fit the door locks. That is just a choice you will have to make.
