Many people choose to have a keypad installed on their gate for easy access reasons, and so that other people can temporarily get a code to open the gate. These codes are easy to reprogram, so changing them often will increase your security and make you feel at ease that people you do not want to have the code don't have it.
If the rollers or other parts seem stuck, you can try brushing on some kerosene to the parts. If they are rusty, use steel wool to take away the rust and lubricate as usual. If they are badly corroded they may need replacement. You also need to take a look at the opener. If it is operated by a drive screw or a chain, you may need to lubricate these parts as well.
Garage doors and gates over time will require repairs and even replaced parts because of the wear and tear that is normal with them. Opening and closing a garage door will weaken the tension springs that control the door itself. Other things that are normal and will need repair is the motor it self that opens and closes garage doors or even a gate.
De-icing products will also do the trick. If you are sure that you won't damage the door, you could also use a flat shovel to break the ice. The skilled (and lucky) people will manage to open the door and in this case make sure to clean all water and ice from the spot where the floor and the garage door meet. This way you can ensure that the garage door will open the next time you need it.
