Choosing the Right Locks for Your Home

Your home's locks are its first line of defense against intruders. Choosing the right locks involves understanding different types, security grades, and features that match your specific needs.

Understanding Lock Grades

The American National Standards Institute (ANSI) grades locks based on security and durability:

• Grade 1 - Highest security, commercial-grade quality. Suitable for high-risk areas or homeowners wanting maximum security.
• Grade 2 - High security, good for residential use. The recommended minimum for exterior doors.
• Grade 3 - Basic security, suitable for interior doors or low-risk areas.

Types of Home Locks

Deadbolt Locks

The most important lock for any exterior door. Unlike spring-bolt locks, deadbolts extend deep into the door frame and cannot be pushed back without the key or thumb turn. Look for deadbolts with at least a 1-inch throw.

Knob Locks

Common but should never be the only lock on an exterior door. The lock cylinder is in the knob itself, which can be vulnerable to breaking. Use in combination with a deadbolt for exterior doors.

Lever Handle Locks

Similar to knob locks but with a lever instead of a round knob. Easier to operate, making them ADA-compliant and good for people with limited hand mobility. Use with a deadbolt on exterior doors.

Smart Locks

Offer keyless entry via PIN codes, smartphones, or fingerprints. Benefits include:

• No keys to lose or copy
• Remote locking and unlocking
• Temporary access codes for guests
• Activity logs showing who entered and when
• Integration with home automation systems

Electronic Keypad Locks

Enter a code to unlock without needing a key. Useful for families with children who might lose keys. Choose models with a key backup in case of battery failure.

Locks for Different Doors

Front Door

Your primary entry point deserves the best protection. Recommended setup:

• Grade 1 or 2 deadbolt
• Reinforced strike plate with 3-inch screws
• Consider a smart lock for convenience
• Peephole or video doorbell for visibility

Back Door

Often targeted by burglars due to privacy from street view. Needs the same level of protection as front door, if not more.

Garage Entry Door

The door from your garage to your home is often overlooked. Treat it as an exterior door with a quality deadbolt.

Sliding Glass Doors

Require special locks. Consider a double-bolt lock or security bar. Some smart lock manufacturers offer solutions for sliding doors.

Additional Security Features

• Anti-pick pins - Resist lock picking attempts
• Anti-drill plates - Protect against drilling attacks
• Bump-resistant design - Prevents bump key attacks
• Reinforced strike plates - Strengthen the door frame
• Smart lock features - Auto-lock, tamper alerts, and activity monitoring

Professional Installation Matters

Even the best lock provides limited protection if poorly installed. Professional locksmith installation ensures:

• Proper alignment for smooth operation
• Correct depth for maximum security
• Reinforced strike plate installation
• Assessment of door and frame condition
• Recommendations for any additional security needs
