How to Secure Back Doors and Side Entrances

By Caraballo Locksmith – With Caraballo, there’s no failure

The Most Overlooked Entry Points in Your Home

When homeowners think about security, they almost always focus on the front door. It looks strong, visible, and important. However, experienced burglars think very differently. They target back doors and side entrances first.

These entry points are quieter, less visible from the street, and often protected with weaker locks. In Miami, where many homes have side yards, patios, pool access, or alley-facing doors, these secondary entrances become prime targets.

At Caraballo Locksmith, with more than 55 years of experience protecting Miami-Dade homes, we consistently find that back and side doors are the weakest links in residential security. This guide explains how to properly secure them, what mistakes to avoid, and how to bring these doors up to the same standard as your front entrance.

Why Back Doors and Side Entrances Are High-Risk

Burglars prefer speed, privacy, and predictability. Back and side doors offer all three.

These entrances are often:

Hidden from neighbors
Poorly lit at night
Used less frequently
Secured with older hardware

As a result, forced entry attempts here are far more common than most homeowners realize.

Common Security Mistakes on Secondary Doors

Before discussing solutions, it helps to understand what usually goes wrong.

Relying on Knob Locks Only

Many back doors still rely on:

Basic knob locks
Builder-grade hardware
Worn mechanisms

As discussed in many break-in investigations, knob locks alone provide almost no real resistance.

Weak Door Frames and Strike Plates

Even a good lock fails if:

The strike plate is thin
Screws are short
The frame is rotted or cracked

Force transfers to the weakest component, not the lock itself.

Poor Visibility and Lighting

Dark entrances give intruders time to work without being seen. Unfortunately, many side entrances have:

No exterior lighting
Burned-out bulbs
Landscaping that blocks visibility

Step One: Upgrade the Locking Hardware

Install a High-Quality Deadbolt

Every exterior door must have a single-cylinder deadbolt at minimum.

Deadbolts:

Extend deeper into the frame
Resist force far better than latch locks
Prevent easy kick-ins

For Miami homes, corrosion-resistant deadbolts are essential.

Avoid Double-Cylinder Deadbolts

Although they may seem more secure, double-cylinder deadbolts:

Can violate fire codes
Slow emergency exits
Create safety risks

Most professionals recommend single-cylinder deadbolts paired with other reinforcements.

Consider Keypad or Smart Deadbolts

For side entrances used frequently, keypad or smart deadbolts offer:

No-key convenience
Temporary access codes
Easier control over access

However, they must include true deadbolt hardware, not just electronic latch systems.

Step Two: Reinforce the Door Frame and Strike Plate

Heavy-Duty Strike Plates

A reinforced strike plate should:

Be made of solid steel
Use 3-inch screws
Anchor directly into wall studs

This single upgrade dramatically increases resistance to forced entry.

Door Frame Reinforcement Kits

In high-risk areas, locksmiths often install:

Frame reinforcement plates
Door edge guards
Anti-splinter devices

These spread impact force across the frame instead of allowing it to crack.

Step Three: Evaluate the Door Itself

Hollow-Core Doors Are a Major Risk

Many back and side doors are hollow-core, especially in older Miami homes. These doors:

Break easily
Do not support strong locks
Fail under minimal force

Upgrading to a solid-core or metal door provides immediate security improvement.

Sliding and Patio Doors Need Special Attention

Sliding doors are common targets because:

Factory locks are weak
Tracks can be lifted
Glass invites forced entry

Security solutions include:

Secondary locking bars
Anti-lift devices
Reinforced locking systems

Step Four: Improve Visibility and Deterrence

Exterior Lighting

Motion-activated lights:

Startle intruders
Draw attention
Reduce hiding opportunities

They should cover:

Door areas
Walkways
Fence lines

Landscaping Awareness

Trim bushes and hedges near doors. Dense landscaping provides concealment rather than beauty when placed incorrectly.

Step Five: Control Key Access

Rekey Secondary Doors Regularly

Back and side doors often:

Use older keys
Have been rekeyed less often
Accumulate unknown copies

Rekeying restores control over who can enter your home.

Avoid Hiding Spare Keys Nearby

Intruders know all the common hiding spots. Instead:

Use a lockbox
Share access codes
Work with a locksmith

Step Six: Alarm and Sensor Integration

Door sensors on secondary entrances:

Detect forced entry
Trigger alarms immediately
Integrate with smart systems

Back and side doors should always be part of your alarm coverage.

Miami-Specific Factors to Consider

Humidity and Corrosion

Locks exposed to salt air degrade faster. Regular inspections and lubrication help prevent failure.

Rental and Multi-Occupant Homes

Homes with:

Tenants
Roommates
Frequent guests

require stricter access control and more frequent rekeying.

Why DIY Security Often Falls Short

Homeowners often underestimate:

Installation precision
Frame reinforcement
Lock compatibility

Professional installation ensures all components work together properly.

Final Thoughts

Back doors and side entrances are not secondary to burglars. They are often the first choice.

If these doors are protected with weak locks, poor frames, or no visibility, your home remains vulnerable—no matter how strong your front door is.

Securing every exterior entrance equally is the only reliable strategy.
