If the door mechanism is frozen, the previous steps didn't help or you don't feel confident conducting those repairs by yourself, contact a professional to fix the lock. If for some reason you can't seek professional help, replace the lock by yourself.

To replace the car door lock, acquire a pair of gloves, a socket wrench and a tool to remove the panel. After that, take off the door covers and screw heads. Be careful during the removal, as you may break the covers.

Remove the plastic panel around the lock, and detach the lock from the electrical system of the car by taking out a plastic connection device. Remove the rod that is located to the left of the latch in a hole, and remove the latch. Set the new car lock into place, connect it by attaching the rods back, and put the system back together in the reverse order.
