Lubricate the door locks, as well as the hood and trunk locks, with oil.
The lock cylinder can only be lubricated with graphite. To do this, simply turn the key in the lock several times, after having dipped it in graphite powder.

Using a screwdriver, remove the plug from the side of the door lock and lubricate the lock with a couple of drops of motor oil. Lightly lubricate the sliding surfaces of the locking pins and locking plates.
