A method of detecting an attempted lock bumping and providing a notification that an attempted lock bumping has occurred. A lock bumping detection device is placed on or in a door or door jamb near the lock. The device includes a sensor which senses energy and generates a signal that is processed to determine if the energy is a result of a lock bumping procedure. The sensed energy is analyzed to generate a received energy signature, which is compared to a stored energy signature with respected to qualifying and disqualifying rules. If the result of the comparison is positive, this indicates that the energy sensed is a result of an attempted lock bumping procedure. In the event that it is determined that the energy is a result of an attempted lock bumping procedure, then an alarm signal may be transmitted to an associated alarm system.
