The locking hood pins (that use a key) are nothing really brutal, just some 1/8" roll pins that when you lock them turn and catch under the dog-ears of the lock, really not strong but prevent the casual thief from popping open your hood to take his pick of what is there. The regular hood pins are about 5/16" type stanless pins that if locked down with a circle ring etc really will hold the hood down. I use the locking pins together with regular hood catch to keep the hood locked down as my car is on the street every day and I don't wat to find the coil missing or the ignition box gone etc, the real hood pis are more intended for sport and safety, they will stop the hood flying open if the regular hood carch is gone or sprung open.
