A tamper resistant lock is provided. The tamper resistant lock comprises a primary locking mechanism for locking and unlocking the tamper resistant lock with an appropriate key. A secondary locking mechanism is engaged and prevents unlocking when a sufficient force is applied to the tamper resistant lock. The force may be the result of driving a screwdriver into a keyway of the lock in an attempt to forcefully unlock the lock.
