I'm giving these locks 2 stars because that's how many days they lasted. i read the descriptions and was reassured they are stronger than hardened steel, have extra internals to resist prying and lock cylinders are pick-resistent. These were securing storage containers and were twisted open overnight just after installation. Best look elsewhere if you have high-value goods to secure. Oh, and there's no warranty on them either.

Bought 2 heavy duty like-keyed locks for storage unit. WORTHLESS actually worse than that. 10 minutes to open first lock and second one never opened even after using WD40. Finally key broke off in the lock & had to have storage company cut it off.

Horrible. Not even a month old and two of the number wheels are jammed. Spoke with Master lock customer service line. They confirmed they can offer no support. Luckily this happened in the open position otherwise we would have waisted more then just the cost of the lock having to have a lock smith come out. It was a waist of $50 with the lock breaking less then 4weeks old

On 15th September 2023 I sent an email query about a product (which, as far as I can tell, is working OK at the moment), but have had no reply to date ......................

Do NOT purchase one of these locks. Have only had it for 2 days and the combination is no longer working. Absolute waste of money.

We purchased one of their bluetooth lock box's back in Sept 2022, the date today is Aug 2023. The key safe was easy to install but somewhat a little tricky when trying to connect up to the phone app, eventually after many tires, we managed it and got the key safe working as intended. We purchased this key safe for the sole purpose of storing a key which would allow care staff, emergency services, community nurses access to my fathers property - he has very poor mobility and it's not always possible for him to get to the door. After installation, everything worked as intended, all the different services had their own number and all was good. However a couple of weeks ago (14th Aug 23), I received a phone call from the care staff, they could not gain access, the key safe was not opening. Naturally, I thought the battery might be low so I head round with a 9V battery to place on the emergency terminals at the bottom of the key safe and open it with my primary code, and a new battery to replace the old one within the unit. But when I arrived, the battery was not low, and the 9V battery I had to jump start the key safe made no difference, the key safe just did not want to open. Normally, you enter your code, the circular button turns green, there's a 'click' noise which indicates the mechanism has unlocked and you can pull the door open. What was actually happening was - Code was entered, light goes green, NO CLICK, door won't open. Even with the 9V battery attached, NO CLICK, door wont open. At this point, I started to become concerned, of course we have spare keys, but no other mechanism to externally store them securely on my fathers property. I tried to contact Master Lock to obtain some support - well I can tell you after a week I've had no email response from Master Lock and when you call the UK number, you can only speak to an answering machine. Their phone system states they are open Monday to Friday 9am to 5:30pm, however their phone system does not allow you to leave a message until 9:10am A day and a half goes by after the initial call from the care staff not being able to get the key out, at this point I've tried opening the key safe 15 to 20 times with no success, I was about to take a hammer to the key safe to obtain the key and replace it with a different brand, but my other half insisted I tried again, so I did. This time, the key safe sprang into action and opened - I was gob smacked!! I take the key out and close the door to the key safe, I re-enter the code and it opened!!, I go to close the key safe door, but I cannot, the door won't close, so I re-enter the code and the light goes green, but I cannot close the door and there was no 'click' noise, after several attempts, I managed to get the door to close, but now it won't lock and you can just pull it open, I re-enter the code and no 'click', you can still open the door. So now I'm thinking that this unit is faulty because it's just throwing random problems - not being able to open it for a day and a half, cannot get the door closed after being opened, now it won't lock at all!. To summarise, I don't have confidence in this key safe, I work for an NHS ambulance service in the UK and I DO NOT recommend this key safe, Master Locks support is shocking. I will be replacing this key safe regardless of its current working condition with another brand, more likely a mechanical lock also.
