[4] The lock is typically engaged via a small switch on the edge of the door that is only accessible when the door is open. Some cars [5] implement the child lock control as a rotary mechanism which can only be operated with a key. This design ensures the child lock remains in position, preventing passengers from changing the lock position when ...
Many combination locks have three wheels, but the lock may be equipped with additional wheels, each with a drive pin and fly, in a similar manner. The number of wheels in the mechanism determines the number of specific dial positions that must be entered to open the lock, so a three-sequence combination is required for a three-wheel lock.
Modern time delay combination locks can have many functions such as multiple different codes, pre-set time lock settings (open and close times), pre-set vacation times (e.g. Christmas Day), dual code facility, and a full audit trail providing a detailed record of the lock history showing who opened the lock, when and how long it was open.

Many exit control locks are based on magnetic locks. One type, delayed egress magnetic locks, will not allow the door to open immediately. This allows a guard to get to the door before the door opens. It will also release if there is a fire alarm or power failure, but otherwise these locks hold the exit doors shut. These units are common in ...
Also called fail-open. In this configuration, applying electric current to the strike will cause it to lock. It operates the same as a magnetic lock would. If there is a power failure, the door opens merely by being pushed or pulled. A new trend is a strike that is quickly reversible from fail safe to fail secure (and back again if needed).
A security concern with any remote entry system is a spoofing technique called a replay attack, in which a thief records the signal sent by the key fob using a specialized receiver called a code grabber, and later replays it to open the door. To prevent this, the key fob does not use the same unlock code each time but a rolling code system; it ...
