Kwikset 84251-003 – Frequently Asked Questions

1) Do I need the Kwikset 84251 thick door pack to put a 9270 SmartCode deadbolt on a thick door?
If the door is thicker than what the standard hardware in the 9270, 9260, or 9250 box reaches through, yes. The 84251 pack supplies the extension hardware plus an SMT cylinder and keys so the deadbolt tailpiece and mounting screws span the extra material. On a standard door the parts that ship in the deadbolt carton are what you use, and this pack is not needed.
2) What comes in the Kwikset 84251 thick door pack, and do I get keys with it?
Three things: the thick door extension hardware, an SMT (SecureScreen Technology) cylinder, and keys. Because a cylinder is included, this is not a screw-length-only kit, you are replacing the key cylinder on the deadbolt as part of the install.
3) I manage a building with mixed door thicknesses. Can I standardize on Kwikset 9270 deadbolts and use this pack on the odd doors?
That is what the 84251 is for. Keep the same 9270 (or 9260/9250) across the property and add the thick door pack only on the openings with non-standard thickness, so the outside hardware, the user interface, and the keyway stay consistent across the fleet. Two finishes, Black and Silver, so you can match either family of trim.
4) Does the Kwikset 84251 come in a finish that matches my deadbolt?
Two finishes are offered, Black and Silver. Pick the one that matches the exterior escutcheon of the 9270, 9260, or 9250 you are extending, since the cylinder face is the visible piece.
5) Is the Kwikset 84251 a whole deadbolt or just the parts?
Parts only. The 84251 is a thick door pack, it contains extension hardware, an SMT cylinder, and keys, and it assumes you already have a 9270, 9260, or 9250 electronic deadbolt to fit them to. If you are buying for a new opening you need the deadbolt itself as well.
6) Can I use the Kwikset 84251 to retrofit an existing 9250 deadbolt already installed on a thick door?
Retrofit is one of its stated uses. If a 9250, 9260, or 9250-family electronic deadbolt is already on a thick-door opening, or you are upgrading one onto that opening, the 84251 supplies the longer hardware and the SMT cylinder to make it seat properly. No change to the door prep is implied by the pack itself.
7) Does the SMT cylinder in the Kwikset 84251 come with its own keys, and can it be rekeyed to my existing Kwikset keys?
The pack ships with the SMT (SecureScreen Technology) cylinder and keys, so it arrives keyed and operable out of the box. Rekeying it to an existing key is a locksmith operation on the cylinder, not something included in the pack.
