Lockey USA M-210-ABDC Keyless Entry Deadbolt Lock - Mechanical Double Combination Security Door Lock in Antique Brass - Perfect for Homes, Apartments & Offices (Secure Keyless Access)

I love this lock. I bought the kind that has numeric key pads on both sides for my backyard gate. It is great and well worth the price. If you have ever installed a lock on a door with existing holes, you can install this lock in minutes. This lock is smaller than it looks on a website, but when you hold it feels very solid and heavy duty. It is made from thick solid steel except for black rubber pads. Rubber parts are thin gaskets between the door and the lock and , I believe are mostly decorative. Overall construction is high quality and it performs great. It comes with easy to follow instructions tools and parts for changing combination or switching it from left-hand to right hand door. I performed both, it took me minutes and was easy for me. I love the fact that it is weather-proof and is 100% mechanical. No batteries or power required. If you live in colder climates you should know that batteries may not work in 20 degrees or below weather.
