Lost wheel lock

I did a brake job several months ago and now I noticed my wheel lock key is missing. What's the easiest way to get a replacement?

 

There should have been a little insert/pamphlet in your glove box that has your lock ID and order info.

 

If it's an OE set like 'zilla said look for lock ID. If you don't have it and it's an OE item the dealer should have a master set they can go out and try each one to get the right number that they can then order for you. You should be able to get the parts dept guy to go out and figure out what you need and they can order for you. There are like 10 or 12 different ones.

 

I'd try this.
When I had locks, the dealership forgot to give me my key back after a tire rotation.
I went back there a few days later and they had a small box full of them.
Tried them until they found one that fit and gave it to me.

I've since ditched the locks and went with TRD spline lug nuts.

If you bought it new, try the @GODZILLA suggestion and see if you have the paperwork for it.
Chances are McGard made it.
Buy 2 if you can figure out what you need.

This might help..
