We have these PVC sliding windows that have locks that press in until it clicks before you can slide them open. When you want shut the window, you just slide the window shut and the window will lock automatically.
The problem is that these are badly designed locks. I didn't know about this problem until my neighbor with the same window got broken in. They now use a lengthy wooden rod to lock the window. They said the bad guys used a credit card to open the lock. What is a practical way to protect these windows from thieves?
Thanks
