#2 son produced a pair of 9inch long stiff thin flat metal rods this evening and hey presto'd the key-lock within 90 seconds (just like on TV). Now have 4 new AA size batteries in there and it's working like a dream.
Doesn't give you much confidence in the technology though.
I'm now wondering what #2 son does for his second job. Can't recall whether he said he was a steeplejack or whether I just assumed that when he said he was a "second storey" man.
Anyway the safest outcome has been achieved and the contents proved to be quite interesting.
