Losing a Window Key

[newlywed]

Does anyone know what to do if you have lost the key to a window lock and none of the others I have fit the lock doh!

why not speak to your local locksmith in his shop and start the ball rolling. take in some info ie any names you can see on the window maybe and take in the keys that dont fit to show him

thank you, that was all I could think of to do. I thought maybe someone would know of a way to find a serial number etc.

Do you know who fitted the windows? Could you phone them up if so....alternatively they must have a serial number....if the worst came to the worst you could get new handles/locks fitted.

I have a similar problem.
In our newly aquired house conservatory there are three windows and one key- two of them I have managed to unlock after copious volumes of WD40 into the key holes.
Third one refuses to budge. I would try lubrication like that before calling in pro. help.
