I removed the old gasket and put a new window gasket. The leakage was reduced, but it’s still leaking. I suspect the key pads and not the glue between the reed plates, as a missing glue with perfect key pads should not leak (air cannot escape). Do you have an idea of how to effectively check for a key pad leak?
