Top 10 Signs You Need to Rekey Your Locks in Los Angeles, CA

Moving into a new home in Los Angeles, CA? Just went through a breakup? Lost your keys somewhere in Hollywood? There are plenty of reasons LA residents need to rekey their locks — and knowing when the time is right can save you from a serious security headache down the road.

With over 3.9 million residents spread across 503 square miles, Los Angeles has one of the highest rates of lockout calls per capita in the nation. That means lock security is something every resident should take seriously, whether you live in Hollywood, Downtown LA, or anywhere across the LA metro area.

In this comprehensive guide, we will walk you through the top 10 signs that it is time to rekey your locks, explain how the process works, and help you decide whether rekeying or full lock replacement is the right call for your situation.

What Does Rekeying a Lock Mean?

Before we dive into the signs, let us clear up a common misconception. Rekeying does not mean replacing your entire lock. Instead, a locksmith changes the internal pin configuration of your existing lock so that old keys no longer work and new keys are cut to match the new configuration. It is faster, cheaper, and just as effective as a full lock change when your hardware is in good shape.

For Los Angeles homeowners, rekeying is one of the most cost-effective security upgrades available. A professional locksmith in Los Angeles can rekey your entire home in under an hour, giving you peace of mind without breaking the bank.

Sign #1: You Just Moved Into a New Home

This is the number one reason people in Los Angeles call for rekeying services. When you purchase a home, you inherit whatever key situation the previous owner left behind. Real estate agents, contractors, cleaners, dog walkers, neighbors — any of them might have a copy of your key. Even if the previous owner handed over every key they had, there is no guarantee they accounted for every copy. The National Association of Realtors reports that the average LA home has had 3 to 5 different keyholders over its lifetime, many of whom may still possess working copies.

We recommend rekeying within the first week of moving in. It is an inexpensive way to start fresh with total control over who has access to your new home.

Sign #2: You Have Lost Your Keys

Lost keys are more than an inconvenience — they are a potential security vulnerability. If your keys were lost in or near your Los Angeles neighborhood, someone could potentially find them and figure out which home they belong to. This is especially concerning if your keys were on a keyring with any identifying information like a loyalty card, gym membership tag, or labeled key tag. The LAPD recommends rekeying any time keys are lost in a public area.

Sign #3: After a Roommate or Tenant Moves Out

Los Angeles has one of the highest renter populations in the country. If you rent out rooms or have had roommates in your LA property, rekeying is essential when someone moves out. Even the most trustworthy former roommate might have given a spare key to a friend or partner that you do not know about. Landlords and property managers across Koreatown, Silver Lake, and Venice Beach should make rekeying between tenants a standard practice.

Sign #4: After a Break-In or Attempted Break-In

If your home has been burglarized or you have noticed signs of tampering on your locks, rekeying is the absolute minimum step you should take. In many cases, a full lock upgrade to high-security hardware is recommended. The LAPD reports over 14,000 residential burglaries annually in Los Angeles, and police generally advise changing or rekeying all locks after any security incident, even if the intruder entered through an unlocked door or window.

Sign #5: After a Relationship Change

Divorce, breakups, or any situation where someone who previously had authorized access to your home is no longer welcome is a clear signal to rekey. This is not about distrust — it is about establishing clear boundaries and maintaining control over your personal space. Family law attorneys in Los Angeles routinely advise clients to rekey their locks as one of the first steps after a separation.

Sign #6: Your Keys Have Been Copied Without Permission

If you suspect someone has copied your keys without your knowledge, do not wait. Modern key duplication machines are widely available at hardware stores and even some kiosks throughout Los Angeles, and most do not require any authorization. If you have ever lent your keys to a contractor, house sitter, or anyone else, there is a chance copies were made. High-security locks from brands like Medeco and Mul-T-Lock feature patented keyways that cannot be duplicated without authorization — something worth considering if unauthorized copying is a recurring concern.

Sign #7: You Have Old or Worn-Out Keys

Keys that are visibly worn, bent, or difficult to turn are a sign that both the key and the lock internal pins are wearing down. While you might be tempted to just cut a new key, rekeying ensures the internal mechanism is fresh and functioning properly. This is particularly common in older Los Angeles homes in neighborhoods like Venice Beach where original hardware may be decades old and exposed to salt air corrosion.

Sign #8: You Want All Locks on One Key

Tired of carrying a jangling keyring with a different key for every door? Rekeying allows you to set all your locks to work with a single key — front door, back door, garage entry, side gate. This is called keying alike and it is one of the most popular services our locksmith team in Los Angeles provides. It is especially popular among LA homeowners with multiple entry points across their property.

Sign #9: You Are Upgrading Your Home Security

If you are installing a new security system, adding cameras, or upgrading other aspects of your Los Angeles home security, it makes sense to include your locks in the overhaul. Rekeying or upgrading to high-security locks ensures that your physical access points are just as protected as your digital ones. Many LA homeowners pair rekeying with smart home security installations for comprehensive protection.

Sign #10: It Has Been More Than a Few Years

Even if none of the above situations apply, security experts recommend rekeying your locks every three to five years as a general best practice. Lock technology evolves, keys wear down, and you may have given out more copies than you realize over time. Think of it as routine maintenance — like changing your smoke detector batteries or servicing your HVAC system.

How Much Does Rekeying Cost in Los Angeles?

Rekeying is one of the most affordable security upgrades available. In the Los Angeles metro area, you can expect to pay:

• Standard deadbolts and knob locks: $20 to $50 per lock cylinder
• High-security locks (Medeco, Mul-T-Lock): $50 to $100 per cylinder
• Whole-home rekeying (3 to 5 locks): $80 to $200 total

DIY Rekeying vs Professional Locksmith in Los Angeles

While rekeying kits exist at hardware stores, we strongly recommend using a professional for several reasons. First, incorrectly rekeyed locks can jam, leaving you locked out — an ironic and expensive outcome. Second, a professional can assess your lock overall condition and identify security vulnerabilities you might miss, such as worn strike plates, misaligned deadbolts, or substandard hardware. Third, a licensed locksmith ensures the work is done right the first time, which is especially important for high-security or commercial-grade locks.

BH Locksmith USA technicians serving Los Angeles are fully licensed, insured, and background-checked. We arrive in marked vehicles with professional equipment, and we stand behind every job with a satisfaction guarantee.
