A solenoid bolt is a type of electronic-mechanical locking mechanism. This type of lock is characterized by the use of a solenoid to throw the bolt. [ 1 ] Sophisticated solenoid bolt locks may use microprocessors to perform voltage regulation , reduce power consumption, and/or provide access control .
Pressing a button on the key unlocks all of the car doors. Another button locks the car. In 1980, Ford Motor Company introduced an external keypad-type keyless entry system, wherein the driver entered a numeric combination —either pre-programmed at the factory or one programmed by the owner— to unlock the car without the key.
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).
If your car is involved in a crash. or if it breaks down during your commute, here is what you should do, according to the Kentucky Transportation Cabinet. Move your vehicle off the road and stay ...

The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. The magnetic lock relies upon some of the basic concepts of electromagnetism.
Electric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system. There are two basic types of locks: "preventing mechanism" or operation ...
After a mudslide stranded over 100 motorists overnight and indefinitely shutdown a major interstate in Colorado on Thursday, the state is preparing to issue a state and federal disaster declaration.
