When to Replace Your Locks: A Complete Guide

Your home’s security depends on more than just remembering to lock the door. Sometimes, the locks themselves need attention—whether it’s a simple key replacement or a complete lock overhaul. Knowing when and why to update your security hardware can save you from lockouts, break-ins, and costly emergency calls.

Let’s explore the key situations that call for lock and key replacement, plus practical tips to keep your home secure.

Signs You Need New Keys

Lost or Stolen Keys

The moment you realize your keys are missing, replacement becomes urgent. Whether they fell out of your pocket or were stolen along with your purse, compromised keys put your entire home at risk. Even if you find them later, you can’t be certain they weren’t copied during the time they were gone.

Worn-Out Keys

Keys aren’t indestructible. Years of daily use can wear down the metal teeth, making them harder to turn or causing them to stick in locks. If you’re struggling to unlock your door or your key breaks off in the lock, it’s time for a replacement.

Moving Into a New Home

Previous homeowners, contractors, real estate agents, and house cleaners may all have copies of your keys. Getting fresh locks and keys should be one of your first priorities after closing on a property.

When to Replace Your Locks Entirely

After a Break-In

If someone has forced entry into your home, your locks may be damaged or compromised. Even if they appear to work normally, the internal mechanisms could be weakened, making future break-ins easier.

Roommate or Relationship Changes

When roommates move out or relationships end, you’ll want to ensure former occupants can’t access your home. This is especially important if the separation was contentious or if you’re concerned about your safety.

Aging Lock Hardware

Most residential locks last 5-7 years with regular use. If your locks are older, they may not provide adequate security against modern break-in techniques. Upgrading to newer models with advanced security features can significantly improve your home’s protection.

Visible Damage or Rust

Locks exposed to weather can develop rust or corrosion that affects their function. If you notice difficulty turning keys, sticking mechanisms, or visible deterioration, replacement is necessary.

Choosing Professional Help

While some homeowners attempt DIY lock installation, professional service ensures proper fit and function. ABC LOCKSMITH provides expert lock and key replacement services, helping you choose the right security solutions for your specific needs.

Professional locksmiths can also rekey existing locks—a cost-effective option when you need new keys but your lock hardware is still in good condition. This process involves changing the internal pins so old keys won’t work, while providing you with fresh keys for the same lock.

Maintaining Your Investment

Once you’ve invested in new locks and keys, proper maintenance extends their lifespan. Keep locks clean and lubricated, avoid forcing stuck keys, and address minor issues before they become major problems.

Consider creating a spare key plan that doesn’t compromise security. Rather than hiding keys outside, leave copies with trusted neighbors or family members. Smart locks with keypad entry eliminate the need for hidden keys while providing convenient access.
