A compact cylinder lock operated by a key having smooth edges and detents in opposed side faces. The locking mechanism includes series connected pin tumblers and side bars which are resiliently biased. A resiliently biased locking bar having locking lugs extending therefrom cooperates with the side bars and lock housing; the locking bar moving out of engagement with the housing and into gates in the side bars when the side bars are moved a sufficient distance by the pin tumblers. The side bars are provided with false gates which engage the lugs on the locking bar to prevent unauthorized opening of the lock.
