What Happens If You Move Into a New Home? A Lock Security Checklist

Quick Answer

When you move into a new home, rekey every exterior door immediately—before you spend the first night there—because you can’t know how many keys exist from prior owners, agents, builders, or contractors. Next, confirm every exterior door has a deadbolt, reinforce strike plates with 3-inch screws, and address sliding doors with secondary locks. If your locks are builder-grade (ANSI Grade 3), plan a near-term upgrade to Grade 1 hardware.

Moving into a new home in Sugar Land is exciting. Before the boxes are unpacked, there’s one category of task that shouldn’t wait: your lock security.

*Local note:* In Fort Bend County, it’s common for both resale transactions and new construction to involve multiple parties with temporary access—rekeying is how you reset that access cleanly.

New Home Lock Security Checklist (Do These in Order)

1) Rekey Every Exterior Door — Immediately

This is the priority item.

Action: Schedule rekeying for moving day (or the day before).

2) Count Your Entry Points

Walk the exterior and list every outside-to-inside door:

3) Confirm a Deadbolt on Every Exterior Door

Handle locks (knob/lever) alone are not enough. Every exterior entry should have a functioning deadbolt.

4) Upgrade Builder-Grade Locks (If Applicable)

Many new homes ship with ANSI Grade 3 locks. They work—but they’re often the first security upgrade.

A Grade 1 deadbolt is a straightforward improvement that adds real resistance to forced entry.

5) Reinforce Strike Plates & Frames

Replace short screws with 3-inch screws that bite into the wall stud. Consider reinforced strike plates or frame kits on high-risk doors.

6) Secure Sliding Glass Doors

Factory slider latches keep the door closed—they don’t resist force. Add a secondary lock:

7) Reset Codes (Garage, Smart Locks, Keypads)

If any code may have been shared during showings or construction, reset it immediately.
