After the troubleshooting, the problem is still there, so see if it is a problem with the device settings. Sometimes there are always some problems with these electronic things, and it is not excluded that there will be some small bugs when the product is programmed at the factory.

It's a bit of both. First replace the battery to see if the battery is dead, and then check whether the circuit is obviously broken. If these two problems are not, you can call the manufacturer's after-sales service phone and ask them to come to solve the problem.
Observe whether the plug is loose in the line, which will generally not be damaged.
Some have batteries in the cat's eyes! Some are on the side of the door! Take a closer look!
