Apparently I didn’t look around good enough as my missus has found the keys. All is good. lol
By the sound of it, both keys are possibly on the same ring, if true, that is an awful way to treat important keys....
Always have (at least) two copies of each key that are important to you, and store them in two different places.
When I worked for a short time in the morally deficient "LockSmith" trade, it constantly amazed me just how often I needed to open safes (using cutting disks usually), because THE one key was lost.
The second key was usually also inside the safe. How daft can some people get!!!!
I usually asked why the owner did that and the answer was generally the same, there was no safe place for the second key!
I did (jokingly!) say to a couple of safe owners, you should get a second safe, and store the second keys in the other safe....then provided you still have one key for one safe, you can still open both safes!!!
None of them appreciated my humour, but there was a good logic behind the comment, that they simply did not understand.....
Its the same with people wanting all their outside house doors to be opened by a single key, and the costs involved if one of those keys are lost, you may have to replace up to 4 or 5 different locks, just to feel safe again, whereas if each lock has a different key, just losing one key requires only the replacement of one lock.
In the same situation, locks with an electronic PIN number pr password, a different one for each person, can do a better job, plus codes can be altered easily. Not cheap, but little in the way of maintenance costs once installed.....
