Love the ability to change the combination.

I've been using this for my yard gate and its working like new, I only recommend to add some WD-40 every half year and No problems!

Maybe it's from having been outside, but the number dials are harder to turn.

An Excellent indoor lock. The changeable combination is nice for those like me with a poor short-term memory. I can use my favorite numeric combination.

Still, I live in Alaska, and the weather is not the best. I guess there are just too many moving parts inside, but any time I tried using it outside, it kept freezing up. Makes it hard to get back in the house! Regular keyed padlocks have not yet let me down.

Again, a great lock, if you can keep it from freezing.

The lock seems sturdy enough, but the combination recognition isn't very accurate. For example, if I set my combination to 2-4-8-4, the lock will also accept 2-3-8-3 and 2-4-8-3. Regardless, I'm sure it would discourage casual petty theft as any person truly determined to get your stuff would probably just use a bolt cutter anyways.

I went with the trusted Master name and bought this to replace a keyed lock on my patio gate. It looks great and feels very sturdy. Setting the combination was no problem (even with a flimsy setting key), and it opened just fine when I was testing it before locking it onto anything. Snapped it onto the gate, and the first time I used it, it opened fine. The second time, it took a lot of fiddling. The third time... no go. I've had 3 different people try it on several occasions, and it just won't budge. Maybe it's from having been outside, but the number dials are harder to turn. Seems rather silly though, for a bit of rain to affect a lock that's likely to be used outside. So much for having an "easier" lock that didn't require searching for a key to open it. As soon as I can get it off the dang gate, I'm sending it back to Master.

(UPDATE 2-22-2012... ABC News aired a report tonight stating that Master Locks is pulling out of China! Hip-hip hurray... Now, when this lock is made in an American factory here in the USA, you'll see the quality go back to the longtime quality that Master Locks was famous for...)

I've used Master locks since I was a kid in grade school back in the 60s. The name "Master Lock" until today stood for quality, dependability, safety, durability and ruggedness.

About 15 years ago, I purchased 5 of the "set your own combination" padlocks made by Master for use on gates here at my farm and for tool boxes. These locks have stood the test of time outside in bad weather, dust, Texas heat, hail storms, ice, rain and snow and are still giving me great service to this day, which is why I ordered 5 more for tool boxes, gates, sheds etc, here on Amazon.

My new Master Locks arrived this morning, 12-7-2011 and I was eager to change the combinations from the factory setting of 0-0-0-0 (as I have done in the past with my original MADE IN THE USA Master Locks) to the same combination as my older Master Locks. As I examined the locks, I noticed they were no longer housed in a bright brass case, but now came in a regular steel case that was spray painted a dull black. I can only imagine after being outside on a gate, or a trailer, the insides would turn to rust, unlike the old Master Locks that have real brass cases.

When attempting to set the new combinations, one of them would NOT allow me to re-set the combination from the factory setting of 0-0-0-0. Two problems (that I can determine) why this lock would not allow this...

A huge disappointment. I have purchased Master locks exclusively for the past thirty years. I once had a farm and Master combination locks were on all my gates, barns etc. Heavy duty and reliable solid brass locks; they never messed up. A big gap between 1990 when I sold the farm to a few months ago when I needed a combo lock for the gym locker and instinctively chose this Master lock. Today it malfunctioned. It will not retract although set on the correct numbers code. Could it be that the originals were made in the USA and this one is either a counterfeit or are they now all made in China? I have not researched it but maybe someone else has and if so, please share your findings.

I haven't had the chance to actually use the lock yet, so far I only had time to set the combination of the lock, and tried it out couple of times. The lock seems pretty sturdy, however, the numeric pad is a little difficult to turn, which makes unlocking a little difficult. (which could be a good thing I guess) Also, even at the right combination, I have to have both hand on the lock, push and pull the lock really hard for couple of times before I can actually open the lock. Can't imagine what I'll do if it's actually on a locker and I can't get both hand on the lock, but perhaps a little WD40 will help?? Again, this could be a feature that makes lock more secure by making it harder to unlock I guess...

We lock our front and back gates with these locks. They are in the elements, unprotected from sun/rain.

The last ones (same model) were in service since 1994(!), and were good reliable easy to use locks. They were 'used' (unlocked/locked) several times a week. I decided to replace them because the numbers on the combination wheels were becomming a bit corroded and difficult to read, they were getting more difficult to turn (not that bad though), and the lock mecahnism wasn't working as well as it used to. Sometimes the lock didn't latch when locking, and you had to bang it on the gate to get it to latch. I tried lubricating the locks with triflow, which helped for a couple weeks, but then became stingy again. I thought that after 19 years, I could afford to buy a couple more.

So I've been using the two replacements for a month now, and they're great. The numbers are easier to read, the wheels are easy to turn, and the lock mechanism works perfectly. I assume these will last ~20 years like the last set.

By the way, it's a bit counter-intuitive, but to open the lock, set the dials to the combination, then push the shackle *IN* to disengage the lock. Some people set the number, then pull, but that's not it works.
