Review on Lockey USA KEYBOXSN KeyBoxSN Safe by Jeff Drollinger

We bought one of these blocks for use in our hotel to replace the Master Lock blocks which fell apart after only 2 years. The device is well made, the numbers are easy to read, but difficult to open. To change the combination you must unscrew the two screws from the metal plate and then use the tweezers (supplied) to remove the pins used to set the numbers. The pins must be carefully moved to each of the numbers to be used as a combination. As with most push button locks, the numbers can be entered in almost any order and the lock will open, and the numbers cannot be repeated in combination. We opted for devices from the English company "Frost Fire". Their boxes were easier to open and change combinations. I took this device home and used it on my bedroom door to keep the kids out. I was difficult to use and stopped working after about 2 years. The box update no longer works.
