Added this lock to my patio doors to match the builder installed lock on the front door as part of my smart home security system. Love the convenience of locking the doors with the push of a button. Easy to install and easily rekeyed the lock so one key opens both doors. Added to smart home security system with the touch of a button. Very smart indeed.
I like the lock it works very well, however it only last about 2/1/2 years. there is a lifetime warranty on the lock itself but the motor goes bad that automatically unlocks the door with the keypad.
you will have to use the key when that goes bad. I got a real good deal on ebay for one so it was beneficial to me to buy another one even though I know it will only work for a couple of years.
