Salsbury Industries 3390 Standard Replacement Lock for F Series Cluster Mailbox Unit Door with 3 Keys - Secure Mailbox Lock for Apartment Complexes & Neighborhoods

Looks and works like original, except you can remove the key while unlocked. Even the post office would not know the difference. The three keys all worked, just a little rough the first few time inserted and removed, but smoothed out after just a few uses.. No lube or wire brushing was necessary. Very easy install and a perfect replacement. I did find that I could remove the key while the lock was unlocked and the door open. That is not how my original lock worked, but it is not a problem for me. It could be an issue if you leave your box unlocked to the neighbors. I am getting old, but I don't think I'm quite that forgetful YET! Good purchase and I would recommend to a friend, I might even install it for them if they need help.
