    While this product looks nice it is only for indoor use.
    The body of the lock is rather large and it can take a few tries to get it to unlock.
    The price is way too expensive for what you get.

Customer Questions & Answers

  1. A

    No, it is only for a single user and that time frame is determined by the owner. 

  2. A

    While battery life is very dependent on usage, under average use it is about a one-year lifespan. As for temporary function, it is just that, a temporary code that you give to someone so they can gain access. 

  3. Answered by the admin If your phone needs to be in the locker then you can use the directional keypad on the lock to unlock the keypad. You would establish the sequence upon setup.
  4. Answered by the admin A single account can manage up to 250 padlocks. If you need more than that then we will need to get Master Lock involved to work on those user rights.
  5. A
    No, this is not designed for exterior use. However, you can use the 4401 version which is designed for exterior usage.
