Samsung DP728 Smart Door Lock - Can’t change password
crwdns2934249:0crwdne2934249:0:
The fingerprint sensor cover would normally open when I tried to change the password after pressing the reg button from the inside and pressed the existing password from the outside.
But now, without the lifting of the fingerprint sensor cover, when I press in the new password and then confirm by ‘*’, it lock fails to change password....
I could only restore the lock into factory setting and got stuck with factory password! Feeling very insecure. Please help
