Double glazing window handles?

Hi,i have lost the keys for my double glazing window handles and would like to replace the handles with new handles and keys,the old handles are locked and I was wondering how I could remove them as I only have access to one screw,the other screw is covered by the handle thanks

If you know who supplied your windows you may be able to get new keys - they are probably all common-keyed.

Oddly enough there is a wonderful tool called Google that allows one to search the Internet for all sorts of things. Why not give that a try?

I searched for "double glazing keys" and got this as the very first result:
