Excellent realtor boxes!!
Master lock boxes are easy to use, install change the codes on and can hold multiple sets of keys. Very sturdy and hard to remove if you do not have the combo for the box. They fit on most door knobs or water spigets. Definitely very secure and functional!!

Good product but bothersome sticker
Product delivers as promised but I wish they had not put on the sticker that says "Holds 5 Keys" that was not easily removed. Looks like it was placed to stay on the lock.

EXCELLENT KEY SAFE
I'm impressed with the design, features, and build quality of the Masterlock Key Safe. The installation instructions are clear, simple, and easy to follow. I decided to place the safe in a secure location near the front door, not on the door knob itself, but rather to a nearby galvanized water pipe. I've tried it out a couple of times and am pleased with the accessibility and ease of use. I was especially pleased with the tough, rubber-type black cladding that protects the case and the sturdy shackle, and there's even a clever, black cover that slides down to access the 4-digit, rotating combination locking mechanism. And I feel the price is reasonable for such a strong, high-quality product.

Better safe that sorry.
This arrived and was exactly what I needed and I recommend for a lot of folks. Hiding a key somewhere is not a great idea any longer. A way for someone to be able to get into your home in case of emergency or what have you. I live alone with my dog. I have 5 adult children that live less than 40 minutes from me. A lot of my neighbors are snowbirds or travel a lot. So not around often. My kids don’t carry keys to my house either. One day I was talking to one of my daughters on the phone as I was getting ready to go to a special work training on the other side of town. It was as early and only about 100 degrees outside. I was all ready to go, everything in my hands my water bottle, a snack, my bag, so as I held the phone between my ear and shoulder I took one hand and twisted the lock “tossed Hazel her treat yelling good bye” and shut the door. As the door shut. Oh NO!!!! Yep just locked mys of out of my house and my car. My daughter ended up calling a friend that’s a locksmith. He said he could probably break in and just charge her $20 for the call. My house is Fort Knox, I have one of the two unpickable locks, ant get in the windows because I have them all so they will only go up 2 inches. The only way is to break a window. He drilled through the lock and put the kind back in and was stunned that I had one like it. At that point my daughter said “Mom lock box today” for your sake and ours what if we couldn’t get a hold of you and then we couldn’t get in to the house. People need to think about these things, it has now come in handy for me to when one of my kids wants to borrow something from me and I’m not home. They just ask and I say sure and they go get it. So it works for a lot of things, but it’s really a pretty good idea but a lockbox not a hide a key key and the lockbox is pretty simple to use. You can input your own code in there so whatever you want it to be and you can also change it whenever you want to so give it to whomever you want and if you don’t want them to have it anymore, you change it just so simple. There’s also plenty of room inside of it to have a few keys if need be. I believe it’s also fireproof not that you need them to unlock your house but if you have a fireproof safe, I guess that would be a good place to have the key.
