    4.0 out of 5 stars Great locks, but should come with 3 keys; damaged delivery.
    Reviewed in Canada on July 15, 2025
    Verified Purchase
    This is my second time purchasing this Masterlock model. The quality is great and they can withstand all weather conditions without rusting, so long as you properly cap the lock area. I’m giving it 4 Stars because it only comes with 2 keys; ideally there should be one for each. Additionally, the plastic packaging arrived damaged; fortunately, the locks appear to be fine. The seller should refrain from using a standard bag for shipping and consider upgrading to a padded envelope to prevent this issue.

    4.0 out of 5 stars Only two keys
    Reviewed in South Africa on January 9, 2025
    Verified Purchase
    Only two keys are included. It probably makes sense since they are keyed alike, but you need a third key if you want to use them in different locations. It also is a bit risky if one key gets lost.

    Otherwise very strong, uses spherical locking detents so they can't be forced with shims and the rubber housing is very thick.

    5.0 out of 5 stars Nice keyed alike locks from a major brand
    Reviewed in the United States on January 7, 2025
    Verified Purchase
    I think locks are mostly to keep honest people out. That being said, these locks are as sturdy and well made as one would expect. I have found that one of the key points is getting duplicate keys for your locks. Sometimes you need 3 or 4 keys for many locks. Hoping that the no-name brand of locks will have a commonly available key does not work for me. I’ll spend a little bit more on a name brand that I know I can get spare keys for.
