🔒 Top Lock Upgrade Options for Better Home Security

1. Smart Locks

Modern smart locks offer convenience and security through features like:

  • Keyless entry via PIN code, fingerprint, or smartphone app.
  • Remote access to lock/unlock doors from anywhere.
  • Audit trails showing who entered and when.

Popular options: August Smart Lock Pro, Schlage Encode, Yale Assure Lock


2. High-Security Deadbolts

Standard deadbolts can be easily bumped or picked. High-security deadbolts offer:

  • Drill- and pick-resistance
  • Steel reinforcements
  • ANSI Grade 1 certification (highest residential security grade)

Recommended brands: Medeco, Mul-T-Lock, Schlage B660 series


3. Key Control Systems

To prevent unauthorized duplication of keys:

  • Use restricted keyways that only licensed locksmiths can copy.
  • Consider do-not-duplicate (DND) keys for shared homes or rentals.

4. Reinforced Strike Plates and Door Frames

Even the best lock is weak if the door frame gives way:

  • Upgrade to a reinforced strike plate with 3-inch screws.
  • Consider metal door jamb reinforcements to prevent kick-ins.

5. Door Hardware Upgrades

Add-ons to enhance lock security:

  • Door jammers/bar locks
  • Hinge bolts to prevent forced entry from the hinge side
  • Security screen doors with separate locking systems

6. Double Cylinder Deadbolts

Useful for doors near windows:

  • Requires a key on both sides, so intruders can’t break a window and unlock from the inside.

⚠️ Note: May pose a safety hazard in an emergency—ensure quick key access inside.


🛠️ Professional Installation vs. DIY

  • DIY is viable for basic smart locks or strike plate upgrades.
  • Professional locksmith installation is recommended for high-security systems, especially if rekeying or modifying the door/frame is required.

🧠 Tips Before You Upgrade

  • Audit your current locks and weak entry points.
  • Combine physical and electronic security (alarms, cameras, lights).
  • Regularly change codes or rekey locks after moving or losing keys.
