    I purchased the combo Smartkey front door and 660 deadbolt. While the door latch has a collar component, the deadbolt does not come with that same collar assembly (although the instructions clearly illustrates it does exist). Did I miss something?

    installed deadbolt. Inserted key, twisted it to lock. Unlocked it then tried to take key out. I can not get the key out of the lock.. HELP

    Asked by: MoeJoe64
    So I had three exact same thing happen with 3 OUT OF 3 deadbolts I installed. There has to be anther explanation than a defect. Isn't this caused by accidentally flipping the outside/key side upside down during installation? I really think that's the case.... I mean I could be wrong but I went back and flipped over the inner most part of the heavily assembly.... (You know, the part in which you actually insert the key)... anyway ask of my locks work fine now. Granted out could've been something else entirely.... but Im thinking this was 'it'. If tech support would reply and confirm or deny we might have a winner. (I've seen at least 2 dozen of the exact same wisdom posted on numerous websites WITHOUT ANY LEGIT ANSWERS.... I'm thinking that someone REALLY SHOULD figure this out! PREEMPTIVE THANKS TO FTEDXG SUPPORT.... whom I know odd gonna jump on this immediately! Holly

    I'd like to replace an old Kwikset combo set in my front entry door. All of the deadbolts in satin nickel sold byHome Depot are all too large to fit in my steel door with a 1-1/2" diameter deadbolt hole and 2-1/8 doorknob. Do you still manufacture a 1-1/2

    Asked by: Bad Crad
    Hello Bad Crad, Thank you for your interest in Kwikset products. The 780 & 980 series deadbolts will accommodate a 1 1/2" bore hole. These deadbolts come with an adapter that is used when installing on a 2 1/8" borehole but in this case, you would not need the adapter included in the package.
