I can get all of them off but one. Damn wheel lock key doesn't want to bite ! I think the wheel lock pattern is slightly deformed so maybe thats why its not biting. Any suggestions?

 

take a socket that is a little tight and hammer it in to jam it in the socket and open it. That is the easiest way of doin it.

 

How about the Gator grip socket?

I almost had the same problem last time I rotated my tires. If the wheel lock key itself is deformed, you can order a new one. If the lug nut wheel lock is messed up, good luck as I have no idea how you would ever get it off. If it's a factory Mitsubish part them you should take it down to the dealer and make them get if off for you.

 

had the same problem, i fixed it with a hammer and a 3/4" socket...

edit: then I had mitsu buy my 4 new locking lugs.

 

Also your dealer has a master key set of lock sockets; you can swing by and 'borrow' them if need be.

 

this is usually located where your spare is and your jack right?

 

like a few others said..... use a normal socket and tap it on there you'll be able to get it off I had to do it on a car in my auto class not exactly the best method but it works.
