🏡 How to Improve Your Home’s Security (and Know When It’s Time to Rekey or Replace Your Locks)

Whether you’ve just moved into a new home in Ayer, MA, or have lived in the same house for years, home security should always be top of mind. At C and J Lock, we often get asked:
“Should I rekey my locks or replace them entirely?”

Let’s walk through the best ways to secure your home—and how to decide whether rekeying or replacing your locks is the right move.

🔐 What Does “Rekeying” Mean?

Rekeying changes the internal pins of your lock so that old keys no longer work. It’s one of the most cost-effective ways to improve your security without replacing the entire lock.

✅ You should rekey your locks if:

• • You’ve just bought or rented a new home

  • You lost a key and want to prevent unauthorized access

  • A former roommate, tenant, or contractor had a key

  • You want all your locks to work with one key

Pro tip: If your locks are still in good shape, rekeying is faster and more affordable than replacing them.

🔄 When Should You Replace Your Locks?

Some situations call for more than just a rekey.

🔁 Consider replacing your locks if:

• • Your locks are old, rusted, or sticky

  • You’ve experienced a break-in or attempted break-in

  • You want to upgrade to smart locks or high-security deadbolts

  • You’re doing a home renovation and changing hardware styles

Modern locks offer advanced features like smartphone access, auto-lock timers, and keyless entry—all of which increase both convenience and security.

🛡️ Top Home Security Tips from a Local Locksmith

Protecting your home isn’t just about locks. Here are a few extra ways to make your property more secure:

1. Upgrade to Deadbolts

A sturdy deadbolt is your first line of defense. Every exterior door should have one installed properly.

2. Reinforce the Door Frame

Install heavy-duty strike plates with 3″ screws. It’s a small investment that makes it much harder to kick a door in.

3. Use Smart Locks or Keypads

These make it easy to let in family or trusted visitors—without copying keys or hiding them under a mat.

4. Secure Sliding Doors and Windows

Add secondary locks, window bars, or even a basic dowel in the track to prevent forced entry.

5. Maintain Your Locks with PTFE Lubricants

Avoid graphite or WD-40. PTFE-based lubricants like Super Lube or Tri-Flow are cleaner and keep your locks working smoothly year-round.

6. Schedule a Security Walkthrough

A professional locksmith can assess your home and recommend the best upgrades for your specific setup.
