Central locking system

still a problem the other day when it was really cold again and I wanted to de-icing my elk he locked himself up. so from the front.I wanted to free my car from the ice and drive home – I started into the car, engine, out -tuer to and with the scratching started, then all windows were free I wanted to go back into the car but that was locked in the car (motor on, light on).Then after a long try and help from my best friend (DER BUB, best thanks again) came back in again. at home I tried out and see if you open the car with radio remote control,tuer closes, some time does not do anything, the car shuts itself in. of my knowledge it is normal that the car shuts out again, if you open it with radio remote control again and in a certain time I don’t open it, but I did not get in the car itself. now I know it is normal, that the car is closed again best if you open it up again and in a certain time I don’t know that it works.
