Holes for installing lock keepers are worn out

A quick learner from Evansville, IN says:
I have vertical metal windows and need to replace the lock keepers. The repair firm tells me that the holes for the lock keeper are worn-out and cannot be fixed. Could I put a bigger or smaller lock keeper in and simply drill new holes? Or, is there some other method to handle this type of issue?

Bob, we will try our best to find a solution! To better serve you may we see a picture or two of your setup now so that we can get a good idea of what you're working with? Thanks!
A quick learner from Indiana says:
Window Company said the lock keepers cannot be secured to the window due to corrosion of the screw holes. Surely, there is a solution that would work to secure the windows (with or without the lock keepers). Your thoughts????

Hello! I'm afraid I'm not sure what the solution is, either. If the corrosion is so bad that a new lock won't take then your options are limited. I have one thought, though. Take a look at our 26-387 vent lock kit. A vent lock is a device used to prevent the window from being opened to a limited degree, specifically to keep intruders out. See the video below for more information on how it works.
