1) Does it have a master key if anything goes wrong?
2) Will it fit two keys 11cm long and two Yale type keys?
3) Does it slam shut or do you have to re enter the code?
Shân Oswald, Ramsey
This unit does not have a master key for lock out. The internal height of this unit is 130mm so the keys you have should fit. The code is only required when opening the key safe.
What is the maximum number of letter and numbers you can use in your code, for carers to use
Pauline B, Surrey
You can use as many numbers as you wish. Because this safe has a mechanical lock, each number can only be used once and be aware that the number can be pressed in any order to open the safe. Recommend 4 or 5 numbers max.
