door lock problem on 300M

does anyone know how the auto door locks work on the 300M. when we use the key phob the driver door works some time and some time it does not. all other doors work ok. it's just the drivers door. the drivers door works with the key all the time.

thanks.

key phob

I'm not quite sure I understand what you mean. Using the keys or using a button to automatically open the doors?

your problem is most likely the actautor which is serviced as part of the door latch part number 4574151ae thats for a 1999 300m the part costs $99.45 or it should per dcx
the problem is the power actuator is not working properly

I just bought my 300 M recently, its a 99 also, the door lock mechanism is fine, the truck lock button on the entry device worked the first couple of days and then it quit on me. Have to use the key to open my trunk now.
