I was looking for a keypad lock to retrofit my deadbolt that didn't require me to replace all my keys. This lock works perfectly! It has a standard deadbolt cylinder so you can just swap it with the cylinder in your existing deadbolt. It comes with a Schlage keyway, I swapped it with my existing Weiser and all my keys still work.
Eufy security is great, all codes are stored locally in the lock, not in the cloud.
Pin code can be up to 8 digits and you can add random extra digits before your code while unlocking to keep prying eyes confused.
A simple keypad lock with advanced code security, includes time limited, temporary codes and app accessible so you can check the status and lock / unlock remotely. Also has auto locking.
Bonus - I used to have to pull on the door to get the deadbolt to engage so I was worried the autolock wouldn't work but this deadbolt slides in effortlessly.
