died after a few uses - beware

After installing the code and using it successfully several times, I removed it from my locker last night. I didn't immediately lock him up and put him in my pocket and he stood on the bench for a few minutes and was pushed. Somehow, without my intentional doing, the lock has reset to a different PIN and I can't open it! It's useless! The only good thing is that my key/wallet/phone/clothes didn't get stuck in the locker! I need a new lock and there is no way I will be getting a second one likeโ€ฆ

Pros
  • Satisfied so far
Cons
  • Zero

I like the look and feel of the lock. You reset the combination by unlocking the lock and turning the deadbolt sideways where it can slide into the lock body, setting the new combination, and then lifting the deadbolt to its normal height. The problem is that there is no way to disable/prohibit firing the firing pin in the combo reset area when the lock is unlocked during normal use. As a result, after unlocking and re-locking the lock, I found that the combo had changed because it was slipping

Pros
  • GOLS certified
Cons
  • Minor issues

Warning: Combo No. subject to change without notice

This is the basic easy to use lock combo that I wanted after playing around with the spinning wheel style ("Am I walked around twice?* in the order of 2 digit #s?!etc) However, note that the 4 digit number has changed twice, the first time I was completely naked after a shower at the gym trying to do this thing opening..After 15 humiliating minutes I had to ask a stranger to get someone with a lock cutter from reception.Somehow I stumbled across a new number on the 4th wheel.So now I had a newโ€ฆ

Pros
  • Nice touch
Cons
  • A few little things

Unreliable combination settings!

Terrible lock! It changes the combination during daily use. I use it for my gym locker and every once in a while it changes the combo without my help. I used two of these locks. The first lock somehow changed so I couldn't open my gym locker and the gym staff had to pick the lock. I don't know why it happened. After that I used a second lock of the same type. I made sure to close it immediately after opening it and I paid close attention to the combination. Today I took this lock out of my gymโ€ฆ

Pros
  • Robust design
Cons
  • Low maintenance

Don't trust this lock!

I have a smaller padlock with only 3 toggle switches and have never had a problem with it. Looking for a bigger locker for my locker I decided on this one. I read reviews of Revain and thought that the people who said the lock changes the combination without fuss on their part didn't know how to use this type of lock. I thought I would have no problem with that. The second time I used it on my locker, I opened it up, hung it on my locker until it was done, and then just locked it. When I cameโ€ฆ

Pros
  • Free for educational purposes
Cons
  • High price

Combination too easy to change

Ordered this 4 digit master lock (643D) to replace a rusted 3 digit lock that has served me well for several years. I ignored and couldn't understand many of the reviews that said the 643D had an issue with the combination changing unintentionally, as this was never an issue on the smaller 3-digit version. When she arrived I checked the lock. Building the combo was easy. The movement and materials are decent. However, 2 things bother me: 1. When setting the combination, you don't have to pressโ€ฆ

Pros
  • Weight
Cons
  • Lots of stuff

Master 643D on Combination Locks

These padlocks require the utmost discretion from you - they work well with one exception which could potentially render them unusable which is the reason for the 4 stars instead of 5. Toggle switches can move when unlocked. accidentally your own unlock code. You can avoid this by following a few simple steps, which to my surprise aren't listed in the guide. #1 - NEVER move the number wheels when the lock is unlocked. #2 - NEVER move the number wheels when the shaft moves into the 90 degreeโ€ฆ

Pros
  • Absolute Legend
Cons
  • There's Nothing Here
