rx-8 wheel lock key??
 

i lost my key where can i get one is it a stock thing or aftermarket???

I'd say a Mazda dealership, not sure though

Tire shop will break it for $10

Or just, hammer on a silghtly smaller socket and ratchet off and get a new key and locking nuts. Whatever is easiest/cheapest

So break them off and buy new locks or just buy the original key. $10 per wheel is $40 which means he paid more for the removal then to get the key.

I bought a replacement at my dealer for $20. They have all the masters, can fit them and find the one for your car, and should probably have it in stock.

Depends on the year and if they switched lock companies

i keep the key serial code in my glove box. its in my service manual.
