Quick Summary

Upgrading your home security locks is one of the most cost-effective ways to protect your family and property. This guide walks you through choosing the right lock types, understanding smart lock technology, reinforcing entry points, and knowing when to call a professional locksmith. Whether you're a first-time homeowner or simply looking to tighten up your existing setup, these actionable steps will help you upgrade home security locks the right way.

Why Upgrading Your Home Security Locks Matters

Your locks are the first line of defense between your home and potential intruders. Yet, millions of homeowners across North America are still relying on builder-grade locks that offer minimal resistance to forced entry. According to the FBI, a significant percentage of home burglaries involve no forced entry at all — meaning the intruder walked right through an unlocked or poorly secured door.

When you upgrade home security locks, you're not just installing new hardware — you're investing in peace of mind. Modern high-security locks are engineered with advanced anti-pick, anti-drill, and anti-bump features that make unauthorized entry significantly more difficult. Combined with smart technology and proper installation, upgrading your locks can dramatically reduce your risk of break-ins.

Beyond physical security, upgraded locks can also lower your home insurance premiums, increase your property value, and give you smarter control over who enters your home. It's one of the highest-return home improvement projects you can take on.

Step 1: Assess Your Current Lock Situation

Before you spend a dime on new hardware, take a full inventory of your current security setup. Walk around your home and evaluate every entry point — front door, back door, side door, garage access door, sliding glass doors, and any ground-floor windows with locks.

Questions to Ask During Your Assessment

How old are your current locks? Locks older than 7–10 years may be worn and easier to bypass.
Are they grade 1, grade 2, or grade 3? (Grade 1 is the highest residential security rating from ANSI.)
Do your deadbolts have a bolt throw of at least 1 inch?
Are there signs of tampering, rust, or loose hardware?
Do multiple people have copies of your keys — former tenants, cleaning staff, or contractors?

This assessment will help you prioritize which locks need immediate replacement and which can be rekeyed or reinforced. If you're unsure about the quality of your locks, a residential locksmith can perform a full security audit and give you a professional recommendation.

Step 2: Understand the Different Types of Locks

Not all locks are created equal. Understanding your options is key to making smart upgrade decisions.

Deadbolt Locks

Deadbolts are the gold standard for door security. Unlike spring-latch locks, deadbolts require a key or thumb turn to retract — making them far more resistant to kick-in and shimming attacks. Single-cylinder deadbolts are the most common, while double-cylinder deadbolts require a key on both sides (useful for doors with nearby glass panels).

Knob and Lever Locks

These are typically used as secondary locks on interior doors. They should never be the only lock on an exterior door, as the knob mechanism can be broken off with a wrench or hammer.

Mortise Locks

Mortise locks are installed within the door itself rather than on its surface, making them extremely robust. They're common in commercial settings but are an excellent choice for exterior residential doors that see heavy use.

Padlocks

For sheds, garages, and storage units, a high-quality padlock rated for outdoor use provides solid protection. Look for hardened steel shackles and shrouded designs that resist bolt cutters.

Smart Locks

Smart locks combine traditional deadbolt security with digital access control. We'll cover these in more detail in the next section.

Step 3: Consider Smart Lock Technology

Smart locks have gone from a novelty to a mainstream security upgrade. These devices allow you to lock and unlock your door remotely via smartphone, set access codes for family members or guests, and receive real-time notifications whenever your door is accessed.

Key Benefits of Smart Locks

Keyless entry: No more hiding a spare key under the mat or worrying about lost keys.
Access logs: See exactly when and by whom your door was opened.
Temporary codes: Give contractors or Airbnb guests time-limited access without duplicating keys.
Remote locking: Forgot to lock up before leaving? Lock it from your phone.
Integration: Most smart locks connect with Amazon Alexa, Google Home, and home automation systems.

What to Look for in a Smart Lock

When shopping for a smart lock, prioritize models with Grade 1 ANSI ratings, strong encryption protocols (AES 128-bit or higher), and backup key access in case of battery failure. Brands like Schlage, August, and Yale are consistently rated highly for both security and reliability.

Keep in mind that smart locks still require proper installation to be effective. An improperly installed smart lock — regardless of how advanced it is — can be bypassed physically. Consider having a professional lock installation done to ensure your smart lock is fitted correctly and functioning at full capacity.

Step 4: Reinforce All Entry Points

Even the best lock in the world won't help if the door frame around it is weak. Studies show that most kick-in burglaries succeed not because the lock was defeated, but because the door frame itself gave way. Here's how to harden every entry point in your home.

Reinforce the Door Frame

Install a heavy-duty strike plate secured with 3-inch screws that reach the wall stud — not just the door jamb. Strike plate reinforcement kits like the Door Armor or StrikeMaster II are highly effective and affordable.

Upgrade Hinges

Exterior door hinges should be non-removable (NRP) hinges or protected with hinge bolts. A door with exposed hinge pins on the outside can be defeated simply by knocking out those pins.

Secure Sliding Doors

Sliding glass doors are a common weak point. Add a secondary bar lock or Charlie bar in the track, and install a pin lock through both the sliding and fixed frames to prevent lifting.

Don't Forget the Garage

The door connecting your garage to your home interior is often overlooked. It should be treated as an exterior door — equipped with a deadbolt and solid-core construction.

Step 5: Upgrade to High-Security Deadbolts

If you're going to make one single upgrade to improve your home security, make it a high-security deadbolt on your main entry points. High-security deadbolts differ from standard models in several critical ways:

Anti-pick pins: Spool or serrated driver pins that make picking exponentially harder.
Anti-drill plates: Hardened steel inserts that protect against drill attacks.
Anti-bump technology: Bump keys are a known bypass method — high-security locks are engineered to resist this technique.
Restricted keyways: Keys can only be duplicated by authorized dealers, reducing the risk of unauthorized copies.

Top brands to consider include Medeco, Mul-T-Lock, and Abloy, all of which offer exceptional pick and drill resistance. While these locks cost more upfront, the level of protection they offer is well worth the investment for your primary entry doors.

If you've recently moved into a new home, one of the smartest first steps is to have all locks rekeyed or replaced. You never know how many copies of the previous keys are floating around. A lock rekeying service is a quick and affordable way to ensure only you have access.

Step 6: Know When to Call a Professional Locksmith

DIY lock upgrades can be a great option for handy homeowners, but there are scenarios where calling in a professional locksmith is the smarter — and safer — choice.

Situations That Warrant a Professional

Installing mortise locks, which require precise door preparation and cutting
Upgrading to a high-security lock system across multiple entry points
Rekeying after a break-in, lockout, or change in occupancy
Diagnosing and repairing damaged or malfunctioning locks
Installing smart locks if you're uncomfortable with the wiring or app configuration

A licensed locksmith brings not just installation expertise, but also the ability to identify vulnerabilities you might have missed. They can recommend the right product for your specific door type, frame condition, and security needs — saving you money on the wrong purchase and ensuring the job is done right the first time.

Step 7: Maintain Your Locks for Long-Term Security

Even the best locks will degrade over time without proper care. Regular maintenance ensures your upgraded locks continue performing at their peak.

Lock Maintenance Best Practices

Lubricate annually: Use a graphite-based lubricant or Teflon spray — never WD-40, which attracts debris and degrades internal components.
Check for loose screws: Tighten any loose mounting screws on the lock body, strike plate, and hinges every six months.
Test your deadbolt: The bolt should extend and retract smoothly. Any stiffness could indicate misalignment or wear.
Replace batteries in smart locks: Most smart locks alert you when battery levels are low — don't ignore these warnings.
Update access codes periodically: For smart locks and keypad entry systems, change your codes at least twice a year or after any change in household occupancy.

If you notice any lock showing signs of wear, difficulty turning, or visible damage, don't delay getting it serviced. A faulty lock that gives the appearance of security is in some ways more dangerous than no lock at all — it creates a false sense of protection.

Frequently Asked Questions

How much does it cost to upgrade home security locks?

Costs vary widely depending on the type of lock and whether you hire a professional. Basic deadbolt upgrades can cost as little as $50–$100 in hardware, while high-security systems with professional installation can run $200–$500 per door. Smart locks typically range from $100–$300 for the hardware alone.

Is rekeying the same as changing locks?

No. Rekeying involves adjusting the internal pins of an existing lock so that old keys no longer work and new keys do. Changing locks means replacing the entire hardware. Rekeying is cheaper and faster but only makes sense if your existing lock is in good condition and of adequate quality.

Can I install a smart lock myself?

Many smart locks are designed for DIY installation and come with detailed instructions. However, if your door has non-standard dimensions or you're replacing a mortise lock, professional installation is recommended to ensure proper fit and function.

What grade of deadbolt should I install on my front door?

ANSI Grade 1 is the highest residential security rating and is strongly recommended for all exterior doors. Grade 1 deadbolts must withstand 250,000 open-close cycles and 10 door strikes of 75 foot-pounds of force — a significant improvement over the Grade 3 locks found on most new construction homes.

How do I know if my locks have been tampered with?

Look for scratches around the keyhole, unusual resistance when turning the key, a loose or wobbly lock body, or any visible damage to the strike plate or door frame. If you suspect tampering, contact a locksmith immediately for an inspection and possible emergency locksmith service.

🔐 Pro Tip: The most secure homes combine upgraded locks with complementary measures like motion-sensor lighting, security cameras, a monitored alarm system, and reinforced door frames. No single solution provides complete protection — layered security is always more effective than relying on one upgrade alone.
