What Customers Are Saying
Customers overwhelmingly praise this lockbox for its robust security, ease of use, and reliability. Most highlight the strong sense of peace of mind from secure key storage with custom combinations that are simple to set and change. Installation is consistently described as straightforward and tool-free, with intuitive dial mechanisms and clear instructions. The compact design works well for standard house keys, though some note the interior space feels tight for larger items like car FOBs or bulky key chains.

Would RecommendIt’s a box that locks. What’s not to like.
Easy to use
Would Recommend[This review was collected as part of a promotion.] 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
Would Recommend[This review was collected as part of a promotion.] 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 useful to the average person.

Great to secure extra keys
Would Recommend[This review was collected as part of a promotion.] 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.

Great and durable lock
Would Recommend[This review was collected as part of a promotion.] 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
Would Not RecommendThe 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 closes and hits on the key; as a result the door doesn't close.

Well made
Would Recommend[This review was collected as part of a promotion.] 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, easy to open and change the code to one your family will remember. Or ask yo...
