I recently had two Simplex 1011 locks installed. They have a problem where the buttons don’t full reset after entering the correct code. For example, if I have set the code to 1, 2, 3, it correctly works to open the door the first time. However, the next time, the 1 and 2 do not reset, so subsequently just entering 3 is sufficient to open the lock. When pressing 1, 2, 3, it can be felt that the 1 and 2 are “soft” and do not click. After entering a wrong combination, or no combination, and turning the handle, the buttons all reset and 1,2,3 is required again. This is not the desired behavior. Could anyone suggest if my lock installer did something wrong, how I might fix it? Many thanks.
