My t reg polo has central locking - not remote. it worked well and i locked the car the other night.?

wheni went out next morning the key would only unlock the passenger door. if i went round to the drivers side then it would unlock that one but not all the others. any ideas why|||the locking actuator in the driver door needs to be replaced|||I had the same problem last week in my jetta. Give this a try if you are cheap (like me) and don't want to shell out for a new actuator.





(This is made a lot easier with a Haynes manual)





1) Remove the door panel


2) Remove the door lock positioning element


3) On the top you will see a couple wires going into a switch, the switch needs to come out (this is the door locking micro switch) one contact controls "lock" and the other controls "unlock"


4) Check the conductivity of both contacts with an ohm meter


5) If there is no conductivity when you lightly press either of the switches you found your problem.


6) The switch can be further disassembled to expose the tiny spring contacts, give them a shot a break cleaner then some WD-40


7)Celebrate your savings with a cold beer (Or drink of choice)





This fixed mine and I have had no problems since.
