New Home Security Checklist: 10 Essential Steps to Protect Your Home

Moving into a new house is exciting, but every homeowner should start with a new home security checklist to make sure the property is truly secure from day one.

One of the biggest mistakes new homeowners make is assuming their home is already safe. The reality is, you don’t always know who may still have access.

This checklist will walk you through the most important steps to secure your home from day one—giving you confidence and peace of mind.

1. Rekey Your Locks Immediately

This should be your first priority.

You never know who may still have a copy of your keys—previous owners, contractors, neighbors, or service providers.

Rekeying ensures that only you and those you trust have access to your home.

2. Check All Exterior Doors

Inspect every exterior door to make sure it closes properly and locks securely.

• Deadbolts should extend fully into the frame
• Doors should not shift or stick
• Frames should be solid and secure

3. Upgrade to High-Quality Deadbolts

Not all locks provide the same level of protection.

Consider upgrading to higher-security deadbolts if your current hardware is outdated or low quality.

A professional locksmith can recommend the right solution for your home and budget.

4. Secure Sliding Glass Doors

Sliding doors are one of the most common entry points for break-ins.

• Add a security bar or rod
• Ensure the lock is functioning properly
• Consider upgrading to a more secure locking system

5. Reinforce Door Frames and Strike Plates

Many homes have weak door frames due to short screws or poor installation.

Upgrading to 3-inch screws in your strike plate can significantly improve resistance against forced entry.

6. Test All Windows and Locks

Check every window in your home to ensure:

• Locks function properly
• Windows close fully
• No damage or gaps are present

7. Change Garage and Entry Codes

If your home includes a garage or keypad entry system, reset all codes immediately.

This includes:

• Garage door openers
• Keypads
• Smart lock access codes

8. Consider Smart Lock or Keypad Entry Options

Managing physical keys can become inconvenient—especially for families, guests, or service providers.

Smart locks and keypad entry systems allow you to control access without needing to duplicate keys.

• Create unique codes for family members or guests
• Remove access anytime without rekeying
• Track entry activity (on select systems)

These systems can be a great addition to your home when installed properly and paired with a secure locking setup.

9. Evaluate Exterior Lighting

Good lighting is a powerful deterrent against unwanted activity.

• Install motion lights near entry points
• Ensure pathways are well lit
• Eliminate dark areas around the home

10. Schedule a Professional Security Assessment

A professional locksmith can identify vulnerabilities that are easy to overlook.

From lock condition to door alignment and hardware recommendations, a security assessment ensures nothing is missed.
