A pin tumbler cylinder lock includes a shell, a plug, and at least first and second tumbler pins and first and second driver pins. At least the first driver pin extends into a corresponding plug channel when the plug is in a locked condition, such that rotation of the plug with respect to the shell i s blocked. The lock is configured such that at least the first driver pin is separated from the first tumbler pin by a gap when the plug is in the locke d condition. When the first and second tumbler pins are raised without the p roper key and the gap between the first tumbler pin and the first driver pin is eliminated, the second tumbler pin extends across the shear line and int o the corresponding shell channel.
