What if the garage is dead, but it's not your own?

If you can't contact the power supplier or the other party can't help solve the problem, you can consider the following ways:

1. Contact the property management company: If the garage belongs to the property management area, you can contact the property management company for help.

2. Seek the help of professional maintenance personnel: If you have a certain understanding of circuits and lines, you can check whether the power supply line of the garage is normal by yourself, otherwise it is best to invite professional maintenance personnel to check and repair.

3. Replace the battery: If there is no electricity in garage door remote control, you can try to replace the battery.
