Is there a way to get extra keys for this product? We need a total of five keys for our business.

Hello, the product that requires 5 keys needs to be customized from China and shipped from China.

Does the alarm turn off automatically? I don’t want it ringing all day.

LianShi Universal Security Alarm Lock SystemAnti，The alarm lock will stop sounding 30 seconds after the alarm sounds.

Will this work on a trailer while being driven down the road, or will the motion set it off?

It will set off the motion if engaged on the alarm side. I also would not recommend this lock as I have 2 of them and neither work after only having them for 2 months. Bad product!

What is the inside measurement of the shackle? I need it to fit around a 1 3/4 “ pipe
