I have moved into a house with aluminium double glazed windows that of course have no keys for the locks. They are a 3 legged shape that my local glazier doesn't recognise. Can anyone identify the type from attached photo? Thanks, Dave.

Nearest "thing" I have seen and installed are so called, Security Screws, used in an attempts to make removal of a screw "difficult"
Other Security Screws include "Snake Eyes" [two opposing holes in the screw head]
Could be that the lock you have is a screw?
if you think about it? imagine a "Yale" key, with the ridges that operate the lock and its function, which leg of the three in your lock would have the "ridges" ?

Thanks for your reply Ken. I don't think the locks are any kind of security screws, no leg appears any different to any other for a key function. I have always assumed that the right shape would simply insert and twist, perhaps with a push needed, to release the catch. I have tried inserting a cluster of three tiny bradawls but with no luck.

How about?? The lock functions exactly as you describe, correct fitting screwdriver bit, pushes down on a hidden locking plate to allow the lock to function?
Possibly worth a look?? at the top left group of driver bits?

I thought I had every size and shape of security bit known to man. I must have going on for a hundred of them in my garage. But I have never seen a tri-wing bit. So thanks again Ken, I'll try and source one from my engineering mates or even splash out and treat myself to the Draper kit!
