The keyed lug nut on my Dodge 1500 will not come off. It is on there so tight that it has stripped the key. All other lug nuts where extremely tight and hard to get off. Is there any way to get this dang thing off? I am at the end of my rope with this thing....

 

Since it's already destroyed, you could try a chisel and hammer. Like this: (skip to about 1:51)

 

Take a deep socket you can afford to throw away. Hammer it onto the lug nut and twist it loose with a breaker bar. That's what I had to do to mine.

 

Put the other lugs nuts back on, and torque them to the proper spec. THEN try and remove the lock, in whatever manner is required.
