Burgled!!!
Our kids used this key safe after school until a burglar smashed it open one night and burgled our house as my family slept upstairs. It was so disappointing to see how easily and quickly the thin and brittle aluminium casing was breached by the burglar, there is nothing safe about it!

I bought this followed it to the tea on the directions and it will not open . Now it's stuck on my front door and I can't get it off because it will not open. What a big waste of money.

Easy to use
I love this Master Lock box. It is very well built and very durable. It has so many possibilities for use. I chose to use it on my camper to help keep all my keys in one place for summer. I will use it in winter for my snowmobile trailer. I won’t have to worry about miss placing my keys. You could also use it for your home. I would highly recommend it to anyone.

Good for rent houses or showing houses
This lock box is good for showing houses or having keys to a job site. It's not huge so wouldn't fit more than just one or two keys. I do like that you can set the combination to whatever you want. That definitely is handy. I think this would be good for someone showing houses or someone who needs to keep keys at a jobsite but other than that it's not going to be super ...

Great to secure extra keys
The portable lock box is just like one you would see a realtor use. It’s very easy to set your own numbers and begin using. I use mine when I have a friend watch my dog and don’t want to give out the front door code. It’s been a great help for my friend to get easy access to my house and return the key to the box.

Does the job
It just works and does the job, as it's supposed to. No fancy apps and cameras etc, and i like that. Coming from master lock, i feel confident it does as good a job as any at being secure, and that's enough for me.

Great and durable lock
We love this lock. We got it for the fence gate to our backyard and it works perfect. It's also easy to change the code. We change it after we give it to a contractor etc. I highly recommend this product to others!

Poor mechanism and very limited space
The most annoying issue is that this lock will open even if you miss two of the four digits on the combination, e.g it comes preset at 0000; if you set it to 1010, it still opens with 0000. It also has much less space than it looks from the outside. It doesn't fit a safety door key like CISA, because the mechanism takes almost half of the storage space when the door clo...

Well made
This is very solid. Great for keeping an extra key if your teenager is forgetful and forgets his key when he runs out these house and ignores you asking to make sure he has his key. It is also a fun toy for your 5 year old to steal and claim as his own to put whatever he can fit in it. It would also make a great weapon to bonk an intruder on the head with. Works well, ...

This is a great lock to store keys!
I have recently been using this lock and it has been very helpful. It helps me organize my keys outside and keep them in one place. Also, it is very easy to open and close the lock when I need to get a key out.

A Decent Lock Box
I recently got the Master Lock No. 5400D Portable Lock Box for use when we’re out of town and a house sitter needs access to the home. We usually just give keys to our house sitters. But, I figure this approach, i.e., the key is always at the house, hanging on the door, vs. potentially getting lost in someone’s home (which happened in the past) is better.

Perfect for the extra key!
We have this hung in our back door! I love it for when the kids forget their keys or we have family that stop in when we are not home! It’s perfect because the combo is easy to put in even with the younger and elderly hands. The size is great of the key with a key chain. It’s easy to program the code you want and easy to open the top with no additional code once the box...
