How Does A 2 Wire Door Lock Actuator Work

Another symptom of a potential problem with the power door lock actuators are door locks that behave erratically.

How does a 2 wire door lock actuator work.

Solenoid and dc motor. This actuator can move the metal hook shown in this photo to the left or right. Symptoms of a failing door lock actuator. Each door has its own actuator.

I want to use an arduino to activate a two wire actuator automobile power door lock mechanism. Door locks actuators reverse polarity positive switch trigger type d. Both motor legs rest at ground at the relays. On manual locks the locking function operates by pushing or pulling on the door lock.

Be aware this product will draw 8 ma of current 24 7 or 5 8 amp hours per month out of your battery in addition the energy to open close the lock as many times you do that each day or week. Power door locks do not function. In some cars the door lock actuator is positioned below the latch. Car door lock actuators are designed to lock and unlock a door without the effort of pulling on a cable and rod.

Here is an easy 5 wire setup for anyone to use in any vehicle without the use of any relays. To lock or unlock the vehicle polarity is changed on one motor leg via a positive pulse from a switch alarm keyless entry etc. Door lock actuators are made in two styles. The actuator runs off 12 volts.

How power door locks work. The 2 wires named battery red wire after the fuse to positive 12 vdc and the black to ground or minus battery pin. It mimics your motions when you pull the knob up or push it down. If the actuators have any sort of internal or wiring issue it may cause them to rapidly lock and unlock unexpectedly or cause them to function intermittently.

When power is applied the actuator flips in one direction. When mounted in the car it is vertical so the hook can move up or down. Power door locks behave erratically. If the door lock actuator doesn t work with any method then the problem can be the door lock actuator itself the wiring or the control module.

On a vehicle with electric locks the process is a bit different. This manipulates a series of rods that slide back and forth opening and closing the locking mechanism at the door latch. If you reverse the polarity on the actuator and apply power it flips in the other direction.
