These locks keep the vent wing closed, therefore a must, but they're a pain to replace. Start by removing the glass and rubber. Use a 1/8" drill and drill out the original rivets. Next, remove whatever is left of the old lock and install the new lock. Using 1/8" pop rivets, install the head of the lock from the frame side. With a hammer and dolly, very carefully flatten what's left of the rivet on the latch side. Now replace the glass and rubber.
