How do you open a locked window?

To open a locked window, first check if there is a visible lock mechanism or latch that can be easily manipulated. If it's a sliding window, attempt to slide it while gently pressing on the lock to see if it gives. For a more stubborn lock, you might need tools like a flathead screwdriver or a shim to disengage the lock carefully. If these methods don’t work, consider calling a professional locksmith for assistance.
