Only one key is used for garage door remote control, and the other key doesn't work. There is a lock core outside the electric garage, which can be pulled out and opened manually or by pulling the steel wire in the middle. If the common tubular motor for rolling shutter doors has a handle, it can be rolled up a little slowly. If the above two methods fail, you can only go to the manufacturer of electric garage door for repair.

If it is a pirated garage door, there is a lock cylinder outside the door. Open it, pull it out, pull down the middle wire inside, and open the door manually. If it is a shutter door, it is generally a tubular motor with a hand handle, which can be shaken bit by bit.

Extended data:

The whole parking facilities that use mechanical access to park vehicles are called mechanical parking garages, and the mechanical parking garages with three-dimensional storage are called mechanical three-dimensional parking garages, which are mainly multi-plane spatial three-dimensional garages. With the single-storey plane parking garage as the core, the microcomputer, the upper computer, manages and monitors the garage in a unified way, and controls PLC to change the spatial position of the parking space, so that the parking space can be transformed from space to plane, thus realizing the function of multi-storey plane parking.

Refer to the garage proportion when drivers practice piling during training, and add a little more width. I remember it was about 1.5 times the width of the car, and then 50 cm to one meter was enough. There should be at least six meters of clear space in front of the garage. So as to facilitate reversing and prevent traffic jams.
