Not sure if it's some type of security nut, but my tire iron won't take it off. And since I bought the car used, I don't have the stock tire changing tools.

 

That's a wheel lock. You may have to drive over to some tire shops and see if they have a key for it.

 

Check your glove box and trunk carefully for the key. Lift up the trunk carpet and check under the spare tire area to see if it's there. It's usually always in the car. There's no use to keep the key when selling the car.

 

You can take a dremel to it and just cut it off.

 

you get a soket that will fit in there tite and u hammer it in till it gets stuck. then you can put ur rachet or a braker bar on it and there you go it comes off. lololol.....

 

Dealers have universal keys for these.

 

werd just do what big werm said i think it was 3/8 in standard tap in it with a hammer and use a breaker bar i use this on my sis lexus rx300 when i lost her key nut

 

Got them off. Tried going to some local tire shops but they wanted $20 per tire. I tried it with a breaker bar but didn't have any luck. Luckily my friend has an impact wrench. Hammered on a 19mm socket, spun the wrench, and off they came.

 

Now that's brute force!!!
