Works well and seems rugged. I use it to keep an extra set of house keys outside when needed. It looks securely onto my sliding glass door handle. Update 4/2017: This hung on my back door for 5 months. Not a soul ever touched it. As with any locks, including those on your front door, anything can be broken into if someone wants to. So as far as how secure this is goes, well how secure is your door even? How much in your area is someone likely to try to break it open? Those are all factors that go into whether or not this lock is "safe". I am using it now at my Dad's house so that when necessary a caregiver can call me for the code and go into the house. This has saved me twice this week from having to turn around on my way to work and open a door for someone. The code gets change after I give it out, and at times I can just remove the lock if I choose. This beats the alternatives. If someone wants into your home, they will get in anyway whether you have a key box out or not.

In review of the Master Lock 5425D product, I shared it with a dear friend of mine as he was looking for an item like this for his lake home in Northern Wisconsin. He had previously been using a magnetic key 'hider' to hide the house key. We watched three You Tube videos on how to hack a Master Lock lock box. The design of the 5425D makes all three of these techniques (in his opinion) impossible, He had no promlem in installing the 5425D in a much more accessible, but not obvious location. He had some concerns about the cold weather in that location, but believes any good source of heat should solve the problem. He also contacted Master Lock and they suggested some WD-40 for the winter months. He is delighted with this product and its' ease of installation and use.

The key lock box is working fine. It is easy to line up the numbers. The illuminated dial is great. I spray painted it white and it blends with a house better.-less noticeable. I Really appreciate the weather protection cover because it also makes a more attractive package for the front entrance area.

Having had a medical incident last year, I realized that if my neighbor wasn't home, no one could get into my house! Therefore, got this so that another neighbor, friends and house/pet sitter could get in with the 4-digit number. It is very easy to set it for whatever number you want. I didn't want to fasten it to the house nor the front door, so this one is hooked on a small (heavy) metal table on the front porch, which you can't see until you are actually on the porch. Works for me and is an added sense of security as I live by myself. I will note that it held 4 keys for me, so if you need a box to hold more, this may not be the one for you.

I can't tell you how many times I've locked myself out of my place in NYC - usually while running to do laundry at the corner laundromat, or when changing purses! I wanted to keep a hidden key handy, and now have this locked onto the back door doorknob! Keeps my key safe (I've never trusted the "keep it under a flowerpot" trick), and it's great to direct my mom or husband to it when they also inevitably lock themselves out of the house. Also have it in our guesthouse locked to a shelving unit out of sight to hold the keys to our locked owners closet! It's super handy since I always forget to bring my dang key when we go away for the weekend!

• secure • durable • tightly sealed and weather proof, it holds up to the elements outside • easy to open (with correct combination) • small size, easy to mount inconspicuously • good size inside to fit multiple or larger keys After one too many times of being locked out — either through my own forgetfulness or my toddler closing the door behind me — we decided to store a spare key outside in this lockbox. I was familiar with this particular model, because my previous job used this lockbox to store a master key to the building — clearly they trusted it to do its job well and it held up great with different people accessing the lockbox many times a day. For just over 20 dollars, this is a great value and we have had no issues so far (we have had this installed outside for a little over a year). It is also great to have a safely hidden away key for house sitters, when family and friends stay at our house, and to let in handymen/pest control/cleaners etc. when you are not home (without having to hand out copies of house keys). To grant temporary access, we usually switch the combination to an easy-to-remember number sequence and then change it back to "our" combination — this way we are the only ones with permanent access to the key without having to constantly change and remember a new combination.

Originally bought as gift for my nephew, he rents and couldn’t always be around when a repair man was available, he hung it on his front doorknob. Then I bought one as a gift for my 81 year old Mom. She kept going out one door that the wind would catch or suction would grab and lock her out of the house. Very easy to set your own combinations, change as much or often as you like, you can hang it or remove the hanger portion. Love that it lights up, really how often when you lock yourself out of the house do you have a flashlight on you...never. Like the fact can leave a family member coming in town a house key or a repair man then change the combination again once no longer needed. I now want one m makes awesome gift since you rarely think about locking yourself out if the house until you actually do it. Anyone with a home or apartment can use one and that’s just about everyone.

I received my lock today, as expected. The packaging was good, Just a simple Amazon bubble envelope but the lock was in its plastic container. No damage although its pretty tough so there really shouldnt be. Like most packaging, its a struggle to get into without scissors or cutting knife. Instructions are simple. It took me longer to get the keys in than it did to set the combination. Just be sure you write down your chosen combination before closing it. There is a release button on the inside that allows you to raise the shackle to hang on your door. It says it holds 5 keys, but I put my car key and two house keys inside and it seems like it has more room. I bought this to put hang on my apartment door in case I lose my keys while out. I would recommend this lock to a friend.

I bought this because an elderly family member needed care giver to come in. I did read how easy it is to pick the door etc. Well we have an electronic security system and also blink XL night cameras on all walls and so I get an instant video of anyone that comes close to the door. That said, when I do not have a need for this, I will take it out. But I do plan to use an additional dead bolt which can be locked and opened only from inside. Our storm door partially coves the lock. So I am not that worried some one will come and drill a hole. Our neighborhood is extremely secure and there are no apartment blocks and most neighbors have been in the same house for 20 years or more.

Want to avoid sitting alone on the porch until a family member comes to your rescue? Want to avoid the frustration of locking yourself out and having to call a locksmith? Want to avoid breaking your own window to get into your own home just so someone might call the cops on you for suspicious sighting and breaking and entering? If so, this portable lock box with 5 key capacity is for you! This thing is durable! You can put your spare keys in it and never have to worry about being locked out from your home again. Instead of waiting in the cold, your master lock will do that for you. It can weather loneliness as well! Just pet it a few times once in a while so it knows it hasn't been forgotten. Highly recommended. Security Features 5/5 *****. Lock feature 5/5 *****. Weatherproof 5/5 *****. My Recommendation 5/5 *****.
