Introduction

When you back to home driving a car and find the power is off, while the garage door is locked, it can ‘t be opened by remote control, by wall switch or by hand, it is really a bad thing! We suggest fixing an emergency lock on your door. Then you could twist the key and just pull out the lock cylinder, the clutch of the door opener will be disengaged, then just open the door by hand. It is just so easy!
