Over the past few months my automatic door locks have slowed it seems. I have to push them several times for them to completely lock or unlock. And it keeps getting slowly worse. Takes more and more pushes to get them to lock or unlock. ANythign I can do about this?

 

Dirt & grease get on the slides, try wd-40 to clean and smooth out the operation.

 

In addition to that, if cleaning them doesn't help, the motors may be wearing out. Over time, the resistance in the motor can become higher, effectively reducing the workload the lock actuators are capable of performing.
