RELIABILT Knob & Deadbolt Sets
RELIABILT combination sets that include a keyed knob or lever plus a matching deadbolt, keyed alike for convenience.
RELIABILT knob and deadbolt combination sets include a keyed-entry knob (or lever) and a single-cylinder deadbolt, both keyed alike so one key operates both locks. Priced from $25 to $50 per set. Available in all three RELIABILT finishes. Buying the combo set is 15-25% cheaper than purchasing the knob and deadbolt separately, and you avoid the hassle of rekeying to match.
The single-cylinder deadbolt provides a 1" throw bolt for solid locking reinforcement above the knob. Both locks are keyed to the same key code, meaning one key operates both the knob and deadbolt. Two keys are included in every set.

How to Choose RELIABILT Knob & Deadbolt Sets
Combo sets are the right choice for any exterior door where you want both a keyed knob (or lever) and a deadbolt. Buying the set guarantees matching finish, matching key, and a lower total price than purchasing components separately.
Check your door prep before ordering. Exterior doors need two bore holes: one for the knob (2-1/8" diameter, typically 36" from the floor) and one for the deadbolt (2-1/8" diameter, typically 6" above the knob). Most prehung exterior doors come pre-bored for both. If yours has only one hole, you will need to drill the second with a hole saw.
Choose between knob style and lever style based on preference and accessibility. Both options are available in combo sets. For multi-door homes, buy one combo set per exterior door and contractor packs for interior doors in the same finish.
When ordering, verify the finish matches your interior hardware exactly. Combo sets are available in satin nickel, matte black, and aged bronze. A front door with a different finish than the interior hallway hardware is immediately noticeable and looks unplanned.
Quick Installation Tips
Install the deadbolt first, then the knob below it. The deadbolt bore is typically 6" above the knob bore. Use a level to ensure both bores are vertically aligned. If drilling new holes, use the paper template included in the combo set packaging.
After mounting both locks, test the key in each separately and confirm both operate smoothly. Then test locking both simultaneously. On some doors, the alignment of one lock can shift slightly when the other is engaged, so check both together.
Replace the short strike plate screws with 3" screws for the deadbolt strike. This single upgrade dramatically increases kick-in resistance by anchoring the strike plate into the wall framing, not just the door jamb.
Common Problems and Fixes
| Deadbolt does not extend fully | The bolt hole in the door frame may be too shallow. Use a chisel to deepen the mortise in the frame so the 1" throw bolt extends completely. A partially extended deadbolt provides significantly less security. |
| Key works in one lock but not the other | Verify both locks are keyed alike by checking the key code stamped on the packaging. If mismatched, contact the retailer for a replacement or have a locksmith rekey to match. |
| Door is hard to deadbolt | The bolt and strike plate are misaligned. Close the door and observe where the bolt hits the frame. Adjust the strike plate position so the bolt slides smoothly into the frame pocket. |
Long-Term Care for Combo Sets
Lubricate both the knob keyway and the deadbolt keyway with graphite powder every six months. The deadbolt cylinder especially benefits from regular lubrication because it operates under heavier spring tension than the knob lock.
Inspect the deadbolt strike plate screws annually. Replace the short screws that come with the set with 3" screws that reach into the wall framing. This dramatically increases kick-in resistance and is the single best security upgrade for any exterior door.
Clean the hardware exterior with a soft damp cloth. On weather-exposed doors, apply clear paste wax once a year to protect the finish from rain, snow, and UV exposure.
Test both locks together regularly. Open the door, engage the deadbolt and the knob lock, then close the door to confirm both bolts align with their respective strike plates. Seasonal wood expansion can shift the alignment of one lock even if the other still works fine.
Frequently Asked Questions
What does "keyed alike" mean?
Keyed alike means the knob and the deadbolt in the set use the same key. You do not need separate keys for each lock. The two keys included in the box operate both the knob lock and the deadbolt.
Can I buy multiple combo sets that all use the same key?
RELIABILT combo sets from the same batch may share a key code, but this is not guaranteed across different purchases. For multiple exterior doors keyed alike, buy all sets at once and verify the key code matches, or have a locksmith rekey them together.
Do I need a combo set for a garage-to-house door?
Building code in many jurisdictions requires a lock on the door between an attached garage and the living space. A keyed-entry knob alone is usually sufficient since the garage itself is secured. A full combo set with deadbolt adds extra security if desired.
For interior doors that do not need deadbolts, buy passage or privacy knobs individually or in contractor packs. Compare combo set value against Kwikset combo sets.
