About 75% of the time my key works fine, the other 25% it will not work. When it does not work I have noticed that if I manually unlock it, press the button inside to pop the truck, and open then close the truck. Next with the drivers door opened if I lock it with the key it will start working again for a couple of days. I have a new key and have had it back to the dealer countless times for this. The last time they gave me new keys.

Any thoughts??
