There was snow and car was frozen deep into -5 degree. When I opened the car all doors unlocked as normal. I tried to close driver side door after entering into car , it refused to close but when my son pushed hard from outside it closed. Now it is stuck close. It does not open from side and out side including by fob and central unlocking. Other three doors are ok with no issue. Car is 525d 3.0 E60 2007.

and just to you know that all the four locks are clicking and sticks are going up and down. Issue is only driver side lock does not open.

please suggest what to do to open door as nothing is moving.

First thought is it sounds like something was preventing the closure and the extra muscle just mashed it all together and now it's not opening. I'd have someone outside pull the handle open and someone inside leaning very heavily on the inside of the door. When/if it opens suddenly, you may both go flying, so take care. Then figure out what was misaligned or mashed up before closing it again.

 

Sounds like a failed door actuator. Hopefully it will decide to come to its senses when it warms up.

 

Thanks a lot Guys. I will try to push door from inside and see if it works. If not then Is there any way to open door panel from inside of the car?

 

There is supposed to be a manual release lever behind the door panel, but you cannot get to it if you can't open the door. Some people drill through the panel to access it but then you'll need a new door panel.

 

Hi donpb,
Thanks for your suggestion.
Today when I tried to open this door, it opened just like nothing happened to it. It looks like it happened due to snow and freezing conditions like -5 degree. Now because of three warm days, it started working fine again.
So now question is why this happened? I have already sprayed some WD40 in lock area will this solve problem ? or could this happen again during next snow fall? Any suggestion to clear this problem.
Thanks again.
Regards

My guess is that there was some part of the mechanism that got wet and froze during the cold weather (so when it thawed out with the warmer weather, it's fine again).

Or it is also possible that there's an intermittent electrical problem, in which case it'll probably repeat next time the temperatures drop - or not... intermittent problems are like that. ;-)

One other thing - WD40 is great stuff for some uses, but it's not really a lubricant. I like to use something with a bit more sticking power and lubrication, like spray lithium grease (or a host of other types of aerosol lubricants).

It could be that the forced shut just put the mechanism in the wrong position, and that the solenoid in the actuator didn't have quite enough umph until it got warmer.

 

I think the solenoid is wearing out. Since the driver's door gets the most usage, it's typically the first (or only) door lock actuator to fail.
