Master Lock Key Lock Box - Outdoor Key Safe with Combination Lock, 5 Key Capacity - Secure Storage for House Keys, Vacation Homes & Rental Properties

All I know is there are 4 of these on our apt back security gate , one is to access the room where the heaters are and the others are used by people who live here. They never close the black door that keeps dirt out and the gardener has this insane blower that blows filth every where and they one I used to get into the heater room still works. One other has the one with the black cover with the push buttons hanging from the front gate steel U shaped handle and it's still there , another has another type of master lock one that has no shackle and is held the the heavy screen mesh that covers all the gate doors so people cannot reach through and open the gate door by turning the inside knob. This area does have it's share of people who would gladly break one open to get the key but so far no one has tried and all the lock boxes are still there. I have not got mine yet be here on the 29th . I can only conclude it will not be broken into. I got it because in case anything happens to me and my wife cannot walk down the stairs anymore at least she can tell the EMT the combination so they can get in the front security gate and unlock our own security gate at the bottom of our stairs. So 2 keys max. I just hope it works out . I read these reviews the good and bad and really don't feel to thrilled about any lock box's , so I ask what else is there.
