I always assumed buying from Masterlock they would be around and I would never have any problems getting a replacement key. BAD ASSUMPTION. The company no longer makes bicycle cuff locks and won't even bother to service the locks it already sold. Completely unreliable and I will never, ever buy another lock of any kind from them.

Masterlock haven't once replied to the five e mails I have sent to them. Consequently I have used a more reliable and responsive alternative company instead. Shame on you Masterlock lost business, lost trust, lost out

Good with the Bluetooth muscle off except when I wanted to get a spare component for it and they told me I could not and sorry. It was just the shackle metal components post is probably very very easy to and cheap to source

I purchased a 643D Silver colored Master Lock for work. The instructions on the back are not accurate. The very first thing it asks you to do to set your new combination is to: Choose your new four LETTER combination. There are no letters on this lock. It should say NUMBERS, not letters. The spanish translation also says letters. So does the french. WHY???????

Worst lock ever. Don’t buy. I’ve had to spend 40 minutes trying to open this thing up. What does it do?? It doesn’t open. Don’t waste your money on this abomination of a lock.

Je suis un pro en lockpicking, et Master lock... juste ptdr C'est une honte, moins de 0,5s pour les ouvrir de manières général, pour des dizaines d'euros pour certains c'est une vrai honte, je parle même pas de leurs portes sois disant "unpickable" (bahahahaha) Bref une honte n'achetez pas, surtout pour une zone où vous n'allez pas souvent, type une grange, un jardin etc, encore pour un casier pourquoi pas même si il y a bien mieux

We have had a MasterLock Bluetooth Lock box for over a year now, and it has been fairly good, up until it failed. Contacted their support. Waited the 48 hours. Nothing. I'd avoid.

Bought a combination lock and used it only twice. Unable to open it so stuck on suitcase. Connected company twice but no response. Would advise not to buy any Master Lock products.
