Hey there, Thanks for reaching out! What I would suggest would be to install some small washers under the keeper to build it up. The other option is to file down the sweep latch on the lock. Take a look 90-058 keeper shim. This works very well raising up the keeper so the window can lock. However you will need to "tweak" the hole centers a little to fit the 2-1/4" hole centers on the 90-183 keeper. It is important to note this is a temporary fix. If this solution will not work, the next best suggestion would be to get the window framing repaired. Dimensions for 90-058
