I bought a bungalow, with locks on most windows. I can't remove awindow to repair it, without removing the window lock first.It has 2 one-way screws fixing it to the window frame. I can'tdrill into the screws, as they are a hardened metal. I triedgluing a screwdriver the the screwhead with epoxy resin, but thatdidn't work. I could attack the lock with an angle grinder, butI know that will make a mess, and require putting lots of protectivecovering in place first.Any other ideas?

Does the screw head protrude from the lock, in which case maybe you cangrip it with vice-grips.Or use an impact driver:

how to remove one-way screws?

there was no problem IF you knew the trick of a good thump first and a t handle driver (philips 3, not pozidrive)

My wife had an engraving tool in her hobby box. It included a carbide disc about 1 mm thick and 13 mm diameter. With that I could make a slot in the screw heads.
