Review: Wouldn't open - needed bolt cutters - I bought this product several years ago and it worked well. However, I lost the lock and order a new one about two weeks ago. The new one was a dud. I used a couple times successfully. However, the third time I used it the lock seized up and I was unable to open it. The timing was pretty bad because I just got out of the shower and had all my clothes and valuables in the locker. I had to head to the gym front desk in a towel and slippers. I was afraid I was going to have to walk home in a towel and slippers and hope that I could get into my house without keys and cellphone as the gym was getting close to closing. Luckily the gym staff was able eventually open it by using bolt cutters. Now I am on the market for another lock and afraid of getting caught "naked" by buying another dud lock. Wish these locks could be more reliable, not sure what product to buy, any recommendations would be appreciated.
Review: Buyer Beware - I bought my first Master Lock 643D in June 2025. In less than 6 months of intermittent use on a gym locker, I was stranded in a locker room straight out of a shower with a lock that wouldn’t open. After repeated attempts by more than just myself, I had to traipse into the common area of the gym in just my towel and ask an employee to come with their bolt cutters to give me access to clothes,car keys, money and my phone. I know there was no confusion with the combination as it was my husbands birthday and we’ve been married for 40 years - it’s a date I remember. I wrote this all off to a fluke because it was a Master lock… always been considered the workhorse of personal locks. And if you can’t trust Master Lock to keep your stuff safe, who can you trust?!?! Foolishly I ordered another. This one failed after less than 60 days. All hail the bolt cutters! Next time I buy a lock, it will be any brand but Master. What do they say? “Fool me once, shame on you. Fool me twice, shame on me!”
