A gate lock is disclosed for use with swinging gates of the chain link type which includes upper and lower hollow cylindrical housings respectively affixed to adjacent vertical elements of swinging gates. A sliding bolt is in vertical sliding and rotatable arrangement within the bore of the upper housing and is movable between an upper, unlocked position and a lower locked position wherein the bottom of the bolt enters the bore of the lower housing. The lower housing includes a plurality of vertically spaced, key positioning plates which are arranged to require insertion and removal of an operating key in angularly offset relationship from the housing axis. The key positioning plates are further designed to axially align the key after insertion whereby the key head can engage a shaped recess in a threaded locking bolt to threadedly engage and lock the sliding bolt of the upper housing within the lower housing.
