The door lock actuator is an electric actuator that operates the door latch (door pin) mechanism in cars with power door locks. In Nigeria, it is referred to as a "door catcher." In many cars, the door lock actuator is built with the latch mechanism into one assembly. This is why the whole door lock assembly is often called a door lock actuator.

Door Lock Actuator Problems
There are several reasons why a door lock actuator may need to be replaced. Sometimes one of the door lock actuator stops working completely. In some cars, a door lock actuator becomes noisy and produces a squeaking or buzzing noise when power door locks are locked or unlocked.
If the electric motor or the mechanism inside the door lock actuator wears out, the door lock may lock or unlock slowly or work sometimes, but not all the time. In some cars, a failed door lock actuator may lock but won't unlock or the other way around. In most cases, the problem with a door lock actuator is limited to only one door.

The switch that signals that the door is closed may also be built into the door lock actuator. A faulty switch may cause the "door open" warning light to stay on on the dash even if the door is fully closed. If the switch inside the door lock actuator is bad, the whole assembly may also need to be replaced.
A faulty door lock actuator may also cause an anti-theft alarm to go off randomly.
Often, the cable that connects the door lock actuator to the inner door handle may be built in into actuator assembly. If the cable breaks and it's not sold separately, the whole door lock actuator may also need to be replaced.

Testing and replacing door actuators is often complex. I'd recommend taking this to an electrician. If you really want to DIY, a Google search would be helpful for exact steps.
Always double-check your doors to be safe.
