My central lock has worked fine for a month now. Even when its raining or are cold.

What i found after cleaning the lock mechanism was that it has a microswitch like in your PC mouse buttoms. In picture you see the black switch with the red dot on it. This red dot is a water proof rubber seal for the switch pin. This red seal made the switch pin hang when it was cold. In my case it was full of grease. I measured the switch with a multimeter. When pin is pushed inside the doors are locked, when the pin is out the doors are open. So what happend was that when unlocking the car the switch stayed closed. And the other doors sent a negative signal that was telling the driverdoor that they were unlocked. Then you had two negative signals making a short circuit. And then all doors stopped working. So i believe many focuses have this problem. And have probaly changed the whole unit with a new one. But that is expensive.....

Tip: Clean and spray microswitch with WD-40 if you have this problem.
Is this photo taken after removing the inside panel? I still trying to figure out where this is. I too have exactly the same problem on my Ford Focus.

amc49 I almost wrecked a $600 set of connecting rods once by spraying them liberally, the stuff reduced down to a dried bubblegum type goo that no solvent on earth would touch. Finally had to laboriously hand rub it off, it took forever.

Pop as well got the bright idea on one of the nine second drag cars to spray a small shot of WD in plug holes every time plugs were pulled. That engine reduced the stuff down to scar up the cylinder walls weirdly, we stopped doing it and never again had the issue with same type and part engine builds. I like using it for certain things but nothing for long periods of time. I've had it stick up lock tumblers before too but reshooting more in seems to re-break it back down to go back to working again.

sailor Some like the stuff, I've had good luck with it over the years. (WD40)

Driver's door got the treatment about 4 yrs.ago when the handle got loose (pull out far loosely & barely opened the door). Took pulling the inner panel for access, still working fine.

amc49 Wait till you people see what WD40 turns into once it has cooked all the VOC out of it, or very sticky bubblegum...................good way to make the latch even worse one year out.

There are TWO limit switches inside the latch and two other compartments that are virtually impossible to squirt lubricant into. Even using a whole can of WD40. There is an electric motor that if you get WD40 into, will pretty much be scrap once the lube dries out to get very sticky. Luckily they seal that one up pretty much water tight.

mervynskidmore I've had no central locking for the past 2 years so I tried spraying WD40 through the hole and it works now. The only issue is that when opening, only the drivers or passengers door will open, I was hoping all doors would open? It's so long since it worked that I've forgotten. I'm using keyed entry as it's the base model.

boswit Thanks Exsodius!
I had the same problem and was about to change the motor and found this fix. Worked for me and saved me a lot of hassle.
Thanks again.

item109 Thanks Exsodius!

I had same problem about 2 years and now I saved lot of money and time to fix it, thanks to your solution.

For others who want to do this, first time it takes about 3 hours to do this fix.

MilanN First of all I'd like to thank Exsodius for healing my headache with that doorlock problem that i have almost year and a half. Now my door is locking and unlocking like new.

Also I'd like to give a tip, before i did like exsodius said, if you don't have time to remove the lock mechanism from the door and clean and lubricate it, just spray into the side of the two front doors lock mechanism a lot of wd-40 and it will flow underneath the door, shut the door and lock and unlock several times, and it will work. (this is just temporally until you have the time to take out the mechanism from the door and clean it good)

I'm new to this site so cheers to everyone and this thread made me to register myself.
