I first had a basic Master Lock key safe, the type that you have to scroll the numbers and align them. That turned out to be disastrous.

My airbnb guests were struggling to get the lockbox to open. It wasn't clear if you aligned the numbers face on, or slightly lower or higher, and sometimes the box just wouldn't open. Also, some of the airbnb guests would leave the correct numbers on display, so in effect the box was always open.

I soon enough realised that this was certainly not a safe solu...

The Key Safe 5441 is a superbly designed and engineered product. It is solid and sturdy and of a much better construction than other similar products. The app that it uses is cleverly designed and has the ability to issue temporary access codes which can be easily revoked after use. We had ours professionally fitted by a joiner who commented that he thought it was the best key safe he had ever seen and fitted. Although the full functionality of the app takes a bit of getting used to, it can stil...

Excellent. Overcame the problem of being unable to see key pad at night and so far has been reliable. Find app a little difficult but this may be age related. A good buy even if a little expensive.

This is the perfect key safe for renting out our caravan. I can log into the masterlock app which is linked to my safe only, and get a temporary code that will only last 8 hours before it changes, and then email or text that code to the customer to retrieve the keys upon arrival. I can then send another temporary code for when they are due to depart.

Using temporary codes for this purpose is great because I don't have to worry about customers helping themselves to my caravan without paying when...

Does this box alert or lockout if multiple incorrect attempts are made at the 4 digit pin?
Are alerts sent for incorrect pin attempts?

After 3 consecutive unsuccessful attempts using the lock box keypad with less than 1 minute between attempts, the lock box will not accept entries for 1 minute.

How far can you be from device to remotely open it? For example could I open it from abroad?
