I wanted to introduce you to a new type of door lock that uses digital technology to help keep it locked. I thought this could be best used on your patio sliding door because the locks on these doors don't tend to be that good. Sometimes you can just wiggle the door back and forth until the lock opens up. It's really an insecure part of the home and with the right type of digital lock you shouldn't have a problem at locking your sliding door. This type of technology is a little new, so I'll explain to you how it works.
Essentially you can take advantage of electromagnetic forces. This means that you can lock a door with magnetic fields and control it with electricity. A lot of people don't understand how secure this can be. The door will be held closed with a force of 600+ pounds. That means you have to push with force of 600 pounds on the door if you want it to open and no one is going to be able to push that hard on a sliding door unless they have the jaws of life.
This is the best solution for locking your patio door up completely. It will provide the best security for your home.
