Master Lock Heavy Duty Key Lock Box, Outdoor Lock Box for House Keys, Key Safe and Combination Lock, 5 Key Capacity, 5414EC

I just received mine.My impressions:It was larger than the picture makes it look. The locking box is about 2-3/4s square and 1-1/2 deep. From the top of the shackle to the bottom of the box is 5-1/4 inches. (approximates).The inside of the box for keys is 1-3/8ths wide by 1-1/8th tall. So your keys shouldn't be more than 1-3/8ths in length and not more than 1-1/8ths in width at the large end of the key.The box is about 3/4ths of an inch thick. I found I could get half a dozen regular house keys in easily and maybe more. Or maybe fewer keys with thick tops. May not handle long car keys with thick tops with remotes etc.In spite of the product description, I don't see any way a keycard could fit into this box. Most of these that I have seen are about the size of a credit card, which definitely will not fit in. If there are key cards out there that are the width and length of a house key, yes, then. But don't count on it unless you can find and cut out the "sweet spot" on the key card and put that in. Don't recommend.The rest of the box interior is composed of the locking mechanism.I found it held a lot of keys.Two nice features are the vinyl coated shackle and the padded back which prevent scratching of brass handles, knobs etc. Or chipping paint when they bump the doors.I read a lot of the reviews and was surprised at the number poor reviews. Although this is new to me, it appears to work just fine and appears to be strong and sturdy.The case is metal, not plastic. Plastic referred to, I think, in other reviews is the little plastic cover that fits over the combination rings. Not totally essential unless you use in a dirty location where lots of dust could get into rings or where ice may form on them. An issue for all these type of locks.Another plus for this item is that the door swings out and stops at a right angle to the case providing a "little shelf" for the keys to fall into instead of landing on the ground.The lockbox arrived with the combination set to 001. The factory default is 000. So you can see the box wouldn't open until I set the 1 to 0. I think this is done by the factory so the lock front remains in place and doesn't open in shipment. (My guess).This may be the reason for some of the issues with reviews. When you open the lock packaging, make a note of the combination that is showing when it first arrived. It is possible that that me become the factory default by error. But write it down anyway. Then set the combination to 000 and PRESS IN on the door to get it to open.It is necessary to press in on the door to get the latch door to open once you have the correct combination entered. If you just dial the right combination, the cover will remain in place until you push in on it. Then it sort of pops out at you.It is described as an indoor/outdoor lock. And it probably is. I am always a little suspect of these types of locks in heavy winter weather because if you get the thing coated with ice, obviously nothing will move. So if you think you will use it in severe weather, out in the open like a range fence or something, in freezing temperatures, you may want to encase it in plastic, or a Ziploc bag etc.Now for a little on operating the little device.Open the door and observe the interior.On the back wall you will see two brass Phillips screws. To the right of the right hand screw you will observe the base of the shackle with a tiny washer on the end. (You leave that alone.) Between the shackle base and the right hand screw you will observe the "reset pin". This is used to change the combination. To use the reset pin, you press it left with your finger and then pull it forward toward you until it stops. (A little L shape movement.) Left, then forward. It will remain in place.Now dial your desired combination on the combination rings, and reset the "reset pin" back to its original position. Push back and to the right.You now have your new combination. WRITE IT DOWN.If you have trouble remembering combination numbers, consider using the first three digits of a longer number you probably have memorized, and just dial the first 3 of that longer number. I don't suggest using your phone number or address numbers as that is pretty easy for someone to guess.Now, to attach the box to a door knob.You must have the front door latch open for this during the entire process.Look at the back wall of the lockbox. Between the two brass screws you will find the Shackle release pin.Slide the Shackle pin to the right and HOLD IT THERE while lifting the shackle upwards and out of the box. If you turn the shackle slightly the shackle release pin will stay in place and you can let go of it.Loop the shackle wherever you want it and close the shackle. The shackle pin will automatically snapback into place.This must all be done with the front of the box open.If you have a "Lever" type door handle, you may look at finding a fence or pipe nearby to attach the lock to or maybe attaching a padlock type hasp to the woodwork close to the door to attach it to. It is more having a box nearby than necessarily being on your door knob itself. (Door knobs can be pulled off be a determined burglar easily enough.)Now to close and lock keys inside, insert keys, and press front door closed TIGHTLY and HOLD IT TIGHTLY CLOSED while and until you rotate and scramble the combination rings. Now the front door is locked and will stay in place.When opening the box, line up your combination rings and PRESS IN ON THE FRONT COVER. If you forget to press in, it won't open. One reviewer suggested writing on the front cover "push to open" to clue others using it they need to press it before it will open up.Always sit and play with these devices for awhile until you totally understand the mechanisms before attaching to anything or putting keys inside in case you goof up and find it is locked and you can't release it. (If you have it locked to your door knob and can't remove it, you can remove the knob itself from the door and remove the box, then reinstall the door knob.)My opinion is that this is a great little box, especially for the price. Probably just as good as many of the other ones for twice the price. It looks nice, sturdy and well made. I don't understand all the negative reviews.But then this is a new arrival for me and I haven't tried it much. But I'm happy with it.Steve

This new Master Lock lockbox is completely redesigned for the better - all the old quirks have been resolved. This new version is awesome! The shackle can be completely removed, the dials are much easier to see and spin, and there's even a convenient light for night time use. I've bought 5 of them, and they're great!

I use this lock box for my commuter tenant who rents my apt. once per week. It's easy to use and very sturdy.

lock box is sturdy & high quality, even in outdoors setting.It feels strong & secure

This is the first lock box I have been confident to use in my neighborhood. It is a busy city street and a lot of people access my building. No one is getting into this lock box. The problem is that when it rains, the box fills with water. This is a big problem because I keep an electronic fob in the box. Unfortunately I'm going to have to buy a different product. If you can keep the box somewhere where the rain won't get to it, it will be perfect

The best

Easy to use & easy to see. I would definitely purchase this again.

Needed this configuration for an odd sized security door handle/lock.Worked well and easy to use

It's not super intuitive, but it's a well-made mechanism. I had to read the instructions and practice using it for a few minutes but once I got the hang of it, it was pretty straightforward. Basically, there are four things you need to learn to do: open the box, open the lock on top, set the combination and close the box. Not rocket science! It has space for a couple of regular-sized keys. I imagine you could probably fit a longer key (like a car key) but I didn't test it.

It works

Works perfectly for what I need. Numbers are a little hard to read and it’s a wee bit awkward, but totally does the job and well worth the price compared to similar products.

This lock is on an indoor apt.. Ive tried another lock and couldn't adjust it around my doorknob.. This can be adjusted to apt doors, so my lockbox is secure and can't be removed... Works great... Piece of mind for my elderly mom.

This has been an idea for so long and I finally acquired a lock box! Great value. Sturdy, nice backing won't mark door, fits handle well so we can access key and close again.
