Would the heavy frost affect the central locking system in a car?

Since the heavy frost the last couple of days the central locking system in my car has gone bonkers... it keeps unlocking itself! would the frost cause the electrics of a car to malfunction?|||Door locks have always been a problem during cold snaps. Moisture gets inside the door and on the actuators. Then a quick freeze can cause these actuators to get stuck. Sometimes they get stuck in between cycles. This causes the actuator to be stuck in motion and still trying to move. Kind of like stored energy that has not yet finished a cycle. Personally, I think locking the doors is a habit and certainly a very good habit BUT... sometimes in freezing weather they just don't want to unlock. I would not lock the drivers door in such cold weather so at least you can get in and drive home.


Some cars are just known for this problem.|||I doubt that the cold itself is the cause of the fault. Bear in mind that what we in the UK call a "heavy frost" is maybe only -5C or so, which is nothing compared to the winter temperatures that the same car would have to endure in the French Alps, or Scandinavia.


If the car's unlocking itself, chances are there's a fault in the system somewhere, maybe a short somewhere in the wiring. Best bet would be to take it to an auto electrician.|||There are many reasons this can happen. The first is electrical power. If your vehicle has a bad battery and a battery run down prevention relay, everything freaks out. Cold would stress the battery enough to give you some symptoms. Go to one of your local/national parts shop that offers free battery testing. They will let you know if your battery is the problem.





If the car starts fine even when the locks are going crazy, it probably isn't the battery in the car. Computer could be effected by the cold. See if the actuators are "stroking" properly. Basically unlock using the button that controls all the doors and then try to move the door latch levers individually. It could be a bad actuator motor, bad relay, bad switch, all of which are expensive and typically a pain to deal with.





Hope it is just a bad battery.|||Its possible that the frost has formed in the electrical connections, when the frost defrosted moisture will form causing the central locking to short out. My advice would be to spray all the connections with WD40.


Ja.|||Only if the doors are full of water|||you may need new battery in your fob|||it shouldnt really...has to be something else not the frost
