## Description

Double Side Door Lock

Review: 5 out of 5 stars — Buying a second one because it’s that good - We installed this double-sided keypad door knob on our front door before May 2024 and after months of daily use, it has exceeded every expectation. It’s honestly one of the best home security purchases we’ve made — so much so that we’re buying another one right now for our back door. Safety was our top priority. We have an autistic child who can sometimes try to leave the house unexpectedly, and this lock has given us real peace of mind. Because it has keypads on both sides, there’s no simple knob to turn and walk out — a code is required — which adds an extra layer of safety while still allowing quick and easy access for adults. It helps prevent wandering while also keeping our home secure from intruders. The build quality is excellent. It feels solid, durable, and well-made — not cheap or flimsy. Installation was straightforward, programming codes was easy, and the keypad is very responsive. We’ve never had issues with it missing inputs or malfunctioning. Ours is installed on the front door and has handled everyday use and weather changes without any problems. The waterproof and weatherproof design really holds up and still looks and works like new. The key-alike dual cylinders are also a great feature, keeping things simple while providing backup key access if ever needed. This lock delivers security, reliability, and peace of mind all in one. The fact that we’re purchasing a second one for our back door says everything. If you’re looking for a dependable, well-built keypad lock for real-life safety and security, this one is absolutely worth it. Highly recommended.
Review: Great Customer Service - Update: July 13, 2025. This lock is still working great. We LOVE it. Today we replaced the batteries for the first time. We had this lock installed and working, after about 4- 6 weeks we began having issues with the lock not unlocking from the inside. I reached out to Customer Service and they advised me how to correct the problem. After about 2 days, I began having the same issue. I reached out again and they advised me what to do and that corrected the issue for a couple of days and then began to have the same issue. I reached out once more and requested a replacement lock because obviously something was wrong. We could get in the house but we couldn’t get out without using the key. I contacted Customer Service around 7 or 8pm and I had a new replacement lock on my doorstep by 10am the next morning. Now that what I call Great Customer Service. We have installed the new lock and it is working perfectly.

Work as intended. Easy to install. Would have been better if the numbers are more visible without being lit up for easy to see specially at night.
