Locks are the first line of defense in protecting your home, business, and vehicle. Over time, locks experience wear and tear, security needs evolve, and new threats emerge. Knowing when to replace your locks is essential for maintaining safety, preventing unauthorized access, and ensuring peace of mind.
At American Lock & Key in Las Vegas, we specialize in professional lock replacement and security upgrades, helping homeowners and businesses protect their properties with the latest in lock technology. In this guide, we’ll explore the key signs that indicate it’s time to replace your locks, the benefits of upgrading, and why choosing a professional locksmith is the best decision for your security needs.
Signs That You Need to Replace Your Locks
1. Difficulty Turning the Key or Locking the Door
If your key gets stuck, requires extra force to turn, or doesn’t lock smoothly, it’s a sign that your lock is worn out. Over time, internal components degrade, making it harder to lock and unlock the door. Ignoring this issue can result in a complete lock failure, leaving you locked out or compromising security.
2. Your Home or Business Was Recently Broken Into
If your property has been burglarized or there was an attempted break-in, replacing your locks should be a top priority. Burglars often damage locks during forced entry, and even if the lock appears intact, it may have been tampered with. Replacing the locks ensures that your property is secure and prevents future unauthorized access.
3. You’ve Lost Your Keys or They Were Stolen
Losing your keys is a frustrating experience, but beyond the inconvenience, it poses a serious security risk. If your keys are lost or stolen, someone could potentially gain access to your home, office, or vehicle. Instead of taking risks, replacing your locks or rekeying them is the safest solution.
4. Your Locks Are Old and Worn Out
Locks don’t last forever. If your locks are rusty, corroded, or visibly damaged, they may no longer provide adequate security. Weather exposure, repeated use, and aging mechanisms can weaken locks over time, making them more susceptible to picking, bumping, or breaking.
5. You Moved Into a New Home or Office
When you move into a new property, you can never be sure how many copies of the keys exist or who has access to them. Previous owners, tenants, contractors, or even real estate agents might still have a copy. Replacing or rekeying the locks guarantees that only you and those you trust have access.
6. You Want to Upgrade to High-Security or Smart Locks
Traditional locks are effective, but modern security solutions offer enhanced protection and convenience. If you want to upgrade your security, consider installing high-security deadbolts, smart locks, or keyless entry systems. These advanced locks provide better resistance against forced entry, tampering, and unauthorized access.
7. Your Locks Have Been Repaired Multiple Times
If you’ve had to repair your locks repeatedly, it might be time for a full replacement. Constantly fixing the same lock is often more expensive in the long run than simply replacing it with a new, high-quality lock that will last longer and provide better security.
8. You’ve Experienced a Tenant or Employee Turnover
For rental properties, offices, or commercial spaces, it’s essential to change locks when tenants, employees, or contractors leave. Even if they returned their keys, you never know if copies were made. Rekeying or replacing locks ensures that only authorized individuals can enter the premises.

Benefits of Replacing Your Locks
1. Enhanced Security
New locks offer improved protection against break-ins. High-security locks are resistant to picking, drilling, and bumping, making it much harder for criminals to gain entry.
2. Better Convenience
With advancements in lock technology, upgrading your locks can improve convenience. Smart locks, keyless entry systems, and biometric locks eliminate the need for physical keys, reducing the chances of getting locked out.
3. Increased Property Value
Upgraded security features add value to your home or business. A secure property is more attractive to buyers and renters, giving you an edge in the real estate market.
4. Peace of Mind
Knowing that your locks are strong, reliable, and up to date provides peace of mind. Whether you’re at home or away, you can trust that your property is secure.

Choosing the Right Locks for Your Needs
1. High-Security Deadbolts
Deadbolts offer superior protection for homes and businesses. Choose ANSI Grade 1 deadbolts for maximum security, as they provide the highest resistance to forced entry.
2. Smart Locks & Keyless Entry
Smart locks provide remote access, temporary passcodes, and integration with home security systems. They’re perfect for busy homeowners, Airbnb hosts, and businesses that require controlled access.
3. Keypad & Electronic Locks
These locks eliminate the need for keys and allow users to enter a PIN code to unlock the door. Ideal for offices, rental properties, and families who frequently lose keys.
4. Biometric Locks
For maximum security, biometric locks use fingerprint or facial recognition to grant access. These are ideal for high-security areas where key duplication is a concern.
5. Commercial-Grade Locks
For businesses, commercial-grade locks provide durability, high resistance to forced entry, and integration with access control systems. Master key systems and restricted keyway locks offer additional security for offices and warehouses.
