Locksmiths near SE17 from £25 per hour

I have an indoor brass, key-locking espagnolette lock on my window approximately 1.8m. The key is not working and won't turn. The lock is about 40 years old but very much in keeping with the room so I'd like to repair it if at all possible. Can attach photos attached of window, lock and key.
