These are junk do not buy. They are made of super thin material that you can smash open
No, I would not recommend this to a friend.

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.

Burgled!!!
on September 1, 2024
Posted by: Walter
from Melbourne, Australia
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!
No, I would not recommend this to a friend.

A Decent Lock Box

[This review was collected as part of a promotion.] 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.
The lockbox is typical of those you’d see realtors using. It’s fairly large, to provide more storage room. The exterior measures 6.25 H x 3.25 W x 1.5 D. The interior compartment measures 1 H x 2&13/32 W x 1 D. The interior compartment is sized generously enough to fit 5 (possibly more) standard-sized house keys (keys with no oversized/padded key grippers) and/or a few access cards, depending on your use case. Obviously, larger keys and/or keys with oversized/padded grip areas will mean fewer keys inside the storage compartment. The lockbox shackle (which will fit over most exterior door knobs and/or handles) is 1&13/32 L x 1&7/8 W x 13/32 Diameter. Realistically, the lockbox only serves as a theft deterrent and a convenience for those that know the combination. While “beefy,” it is not impenetrable. But, if someone really wants to get inside your home, they’ll find a way… key or no key.
Inside the packaging you get the lockbox and easy-to-follow instructions. The lockbox is so easy to use that, short of the default combination needed to get into the storage compartment, which is already set out of the box… allowing you simply to open the housing, the instructions aren’t needed. However, if you do need the instructions, they’re well written and there for you.
The lockbox housing is a sturdy metal with a vinyl coating, the latter to prevent scratching your door, door knob, etc. While I appreciate the coating, I know from experience with this coating that, over the years, the coating disintegrates and gets tacky (especially when continually exposed to the elements). The change takes a while, but it does occur.
The four-digit combination pad is protected by a cover that slides up and down. The cover seems to stay in place (when covering the digit rollers) via friction… i.e., the pad slides up/over the rollers and you can “feel” the pad’s resistance as it slides over the roller area. This makes me wonder how long the friction will last and keep the cover securely over the rollers. Still, it’s a nice addition that adds an extra layer of protection for the rollers and the lock’s gears.
The thumb-slip opener to the left of the rollers (used to open the faceplate and expose the storage compartment) is fairly easy to use once you input the correct digit combo. After engaging the opener, the faceplate falls forward easily and gives you access (both via slide mechanisms… the first next to the digit rollers, but on the reverse side… the next, next to the shackle at the top-right of the lock housing to, respectively, a) reset the four digit combination and b) open the lockbox shackle. Master Lock also built a safety mechanism into the lock that doesn’t let you close the faceplate without the shackle being first being fully inserted into the lockbox housing. Some might ask, “why?” I think it’s ingenious, as it protects the shackle and/or anything else from being damaged by the pointier side of the shackle. More importantly, it lessens the chance of you forgetting to fully engage the shackle in the lock’s housing… making sure that your keys are stored safely in a fully-locked lockbox.
It must be said that, while well made, this lock box is not waterproof and is not made of water-resistant/rust-resistant materials. Because of this, the lock box is best used under an awning and/or hung on a door knob, etc. protected by a storm door or some other means of cover. If exposed to the elements long-term, and if not properly greased on occasion, to add a layer of protection/keep gears working as well as possible, the metal innards, and depending on the metal out of which your keys are made (and how long they sit in the box exposed to the elements) will rust. For my use case, i.e., placed on our exterior front-door doorknob, protected by a storm door, the lock will be protected and will serve us well, for a long time to come.
So, worth purchasing? Absolutely. The Master Lock No. 5400D Portable Lock Box isn’t perfect. But, when cared for and used/stored properly, the lockbox definitely meets my needs and is an excellent solution to lessen the need to share house keys with house sitters and others. It’s built well, is easy to use, and is a solid four-star purchase all the way. So, if I like it… why not five stars? Five stars goes above and beyond what the manufacturer says a product will do. The Master Lock No. 5400D Portable Lock Box ticks all my boxes and meets my needs. It isn’t out saving kittens from trees. So, a solid four stars it is (which is great in my book). If looking for a lockbox to protect your keys/access cards, etc… while providing added convenience to those that need to enter your home, apartment, and so on… definitely consider the Master Lock No. 5400D Portable Lock Box. I think you’ll be pleasantly surprised.
I would recommend this to a friend!

Well made

[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 you a hundred times to remind them what it is.

Poor mechanism and very limited space
on September 27, 2023
Posted by: HARRY H
from SF CA
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 closes and hits on the key; as a result the door doesn't close.
No, I would not recommend this to a friend.

Hmmm...

It was always a little clunky, but today (2 yrs after purchase), I have to force it closed, and I am concerned it won't open once I do. Going to see if the lifetime warranty is legit since nothing is blocking it, there's no damage, and I am using it correctly.
