Firstly the instructions on the back of the box are practically useless. Some keyframes are so distorted that they cannot be read. It is very important to be able to read the key ID when resetting the master code and other login codes. Luckily there were instructions on YouTube and they were on the website. You just don't have to go to other sources for instructions! The device itself is easy to install and works as described. I wouldn't put it on a door that will be exposed to severe weather. In any case, sun, rain, snow, etc. quickly cause damage. On a garage door or a door with a good storm door, you'll probably be fine. Just watch the sun and how much heat it receives.
