Look for sets labeled “keyed alike” or “all keyed same”. Those packs are designed so every knob/lever and deadbolt in the set works with one key.

• Choose combo or multi-packs: Many entry door lock sets bundle a keyed entry knob/lever with a matching deadbolt on the same key.
• Order enough at once: Keys usually match within the same pack or listing, not across different orders unless noted.
• Check the details: Product pages will say if multiple packs are keyed alike by default.
• Need to match later? If you mix different sets, a locksmith or compatible rekey kit may help align them, but results can vary by lock type.

Many locks list an ANSI/BHMA grade that indicates tested durability and security. While exact performance varies by model, the categories are commonly:

• Grade 1: Highest-rated residential/commercial performance; often used for heavy use or added peace of mind.
• Grade 2: Solid mid-level performance; a frequent choice for exterior residential doors.
• Grade 3: Basic residential performance for standard use.

For an exterior door, pairing a keyed entry knob/lever with a deadbolt can enhance security compared to a knob alone. Also consider strike plates and longer screws for the door jamb. Reviewing a product’s grade and features can help you choose what fits your home’s traffic and needs.

A quick check with a tape measure can help you pick the right entry door lock set.

• Door thickness: Many locks fit about 1-3/8" to 1-3/4". Confirm your door falls in that range.
• Backset: Measure from the door edge to the center of the hole—commonly 2-3/8" or 2-3/4". Many latches adjust between the two.
• Bore holes: Most exterior doors use a 2-1/8" main hole and a 1" latch hole.
• Handing: Levers may be left/right or reversible; knobs are typically universal.

Match these specs with the product description. If your measurements differ from standard sizes, consider a model that lists compatible dimensions.

You can pair a smart deadbolt with a handle or knob/lever to suit how you enter your home.

• Use a passage knob/lever: If the smart deadbolt is your main security, pick a non-locking handle so you’re not managing two keys.
• Key matching: A smart deadbolt may include a backup key, but it won’t automatically match your other locks. Rekeying could be possible depending on the model.
• Check fit and power: Confirm door thickness, backset, and whether the smart lock uses batteries and your preferred connectivity.
• Test features: Auto-lock and app controls can be convenient; try settings to avoid accidental lockouts.

You have a few flexible paths depending on your lock set and preference.

• Included keys: Many keyed entry and deadbolt combos come with multiple keys; check the product details.
• Key copies: Duplicates can often be made at local key-cutting services. Select Walmart stores offer self-serve key kiosks; availability varies by location.
• Rekeying: Some locks accept user rekey kits, while others may require a locksmith. This can align new locks to an existing key or change keys for security.
• Smart alternatives: If you’re using a keypad or fingerprint lock, codes or app access can reduce reliance on physical keys.
