ABSTRACT:
A pin tumbler lock releasing system includes keyway insertible and universally configured lift, key and shim devices that are cooperatively used to raise the pin stacks within a pin tumbler lock to just above the pin tumbler lock's shear line so that the lock's plug element may be rotated within its outer casing in order to disengage its locking mechanism.
