First this is made to perfection. The pin itself just feels so much better then standard pins. Its heavy probably stainless steel. The lock itself was supper easy to setup and when you lock it and give it a twist it feels like it's on bearings, super smooth. Best lock pin made!
I love it, one less key on the key ring is nice , works great , easy to set my key to the lock ! Wish I could get one for each of the cars/truck we have !
