The Masterlock 5400 D is the newest entry into the family of lockboxes and seems to be the best entry yet. (They have only been on the market about a year) Upon viewing this lockbox initially I didn't think it was any big deal. However let me say now that I have used it they seem to have answered nearly every complaint or issue with other brands of lockboxes. If you compare this review to the others on the other brands of lockboxes I have written you will notice the stark differences of this brand of lockbox versus others.

Quality of contruction “9” 

PROS: The Masterlock 5400 D  has an all-metal construction with great looking rubber and plastic ergonomic features that just add to its appearance of quality. It also contains a completely unique feature of a sliding dial cover to protect the dials from the elements.

CONS: The Masterlock is the largest of the lockboxes.

Ease of Use: “9”

PROS: The Masterlock  is so easy to use that a child able to read numbers can open it. Simply give the other person the 4-digit number to access the key storage compartment. The 4 dial system is more secure and does not require sequential steps.  With the ShurLok, if you are off one number, simply correct that number.

CONS: The dials are much larger than the shurlok model but they are still hard to operate if you have long fingernails.

Changing the Combination With Ease: “8”

PROS: The Masterlock has made changing the combo the easiest yes of any other make and model of lockbox. Simply click the change lever set the combo and your done.

CONS: Changing the combo is so easy that a person with bad intent could change it on you. (Not likely but the thought has crossed my mind)

Security: “6”

PROS: The Masterlock 5400 D has 10,000 possible combinations.  Far Superior than Punch Button Lock Boxes which are not near as secure.  For example If your combination on the punch button is 1-2-3-4,  the combination is NOT sequential.  This means that you can open up the lock box on 4-3-2-1, 2-3-4-1, etc. ...ANY combination of those 4 numbers out of 10 can open up the punch button lock box.  This translates into a lock box that is not very secure.  As well as the construction of this box is second to none.
 
CONS: The combo on these does not reset upon being opened. If a person gains access to this box and does not spin the dials then it can be opened by the next  person that tries. Also the lockbox can be stolen the same as the supra models whereas the shackle release can be accessed fron inside the box allowing a person once access is gained to flip the release and steal the box.

Price:  “7”

PROS: The Masterlock 5400 D is a medium priced box Cheaper than the Supra models, but more expensive than the Shurlok

CONS: If price is the issue then the cost could be prohibitive.

Features: These are important to note features to know when making your buying decision:

1.    No Front Face to Lose:  Other brand lock boxes have the common problem of the face falling off the front if it is not clicked back in securely.   With the face falling off onto the ground,  this poses an open invitation for anyone to pick up those keys and access the home. Also,  people often walk off with the front face which means you then have to buy a new lock box. Masterlock 5400 D has solved this problems with an innovative Hinged door that remains open but doen not detach.

2.    Zero Lock: The Masterlock 5400 D can be opened in the dark for nighttime access or the visually impaired.  Simply roll the dials up and away from you until the numbers all lock on zero and then count your numbers in sequential order down from there.

3.    Protection from the elements: The Masterlock 5400 D comes with a unique sliding door that covers the dials and protects them from the elements. This makes the Masterlock ideal for areas with harsh winters.

4. Extra large storage area: The Masterlock 5400 D has an extra large storing cavity so putting in 6 to 10 keys can be done easily and they won't fall out as the hinged door opens from the top so your key won't fall out.
