I got a 9.5psi NST pulley but my SC has a lock on it. It looks like a wheel lock, but smaller. I needed a key. I checked the Toyota dealership in my area, they didnt have it. They said they couldn't open it. Appearently it's a TRD specific part. Does anyone know where I could get a the key to get off this lock?

 

They do this for that reason, so people cant put a new pulley on it then have something go wrong and try to get if fixed under warranty.

However, some have made a key to fit it, not sure if people sell them or not

 

As far as I know I am the only one to have made the key, not for sale. For you just grind down the bolt of weld one on to get it off. It will void your warranty if that matters to you.
