    Unbelievably bad customer service

    I bought a lock box for my elderly mother (5423EURD) and fitted it, following the instructions. The lock doesn't work (it is jammed) so I now have a lock box on a wall that I cannot open. I used the online customer service to report the issue and - despite saying they reply to all contact within 48 hours - they never replied. I tried this twice. I then tried calling and they said the only option was to buy a new box and leave the original one on the wall. They had no advice what-so-ever on how to resolve the jamming issue. Avoid this company like the plague.

    Masterlock thumbs down

    The master lock key safe is supposed to have a lifetime guarantee. My lock failed after 12 months when the internal setting lever snapped. I have reported this twice to master lock who say they will respond in 48 hours but I have not received any response. Needless to say I hall not be using master lock for the replacement key safe I now have to purchase.

    LEAVE YOU STRANDED WHEN THEY DISCONTINUE A LINE

    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.
