Lockey 2835 Passage Lever-Handle Latchbolt Keypad Lock
[DSI-2835]

I wish I had bought this product 25 years ago. My wife wanted it and fortunately I bought 2. Because, once I saw the advantages I installed it on two doors. After six months I had a minor problem with one , I reviewed the instructions and found that I had caused the problem by hitting a wrong button.it took all of 5 seconds to correct the error. The keyless lock people are extremely helpful
