GD00Z-4 Replacement Tilt Sensor

My sensor fell off the door as I used the supplied tape and of course it rolls under the car with no knowledge and gets rolled over.

How can I get a replacement?

Did you ever get an answer to this? I’ve had basically the same problem. I contacted the manufacturer and they were unhelpful. Wouldn’t even sell me a new one.

In the same boat here. I forgot about it and left it attached to the door in my old house.
