Overview: Professional Lock Change Services
When your locks are worn, damaged, or no longer meet your security needs, a full lock change is the best solution. Code Locksmith provides complete lock change and replacement services throughout Los Angeles, replacing outdated or compromised hardware with new high-quality locks from leading brands. Unlike rekeying, which keeps existing hardware, a lock change gives you fresh cylinders, improved durability, and often upgraded security features. Our licensed technicians arrive with the right tools and a wide selection of locks, so you can choose the best option for your property and budget.
When to Change Your Locks
Knowing when to replace your locks can prevent break-ins and costly emergency callouts. Change your locks after moving into a new home or apartment—you never know who may have copies of the previous keys. Upgrade if your locks are over 10 years old, as older mechanisms wear down and become easier to bypass. After a break-in or lost keys, a lock change ensures no one else can gain entry. Locks that stick, require excessive force to turn, or show visible rust or corrosion are candidates for replacement. If you've experienced a tenant turnover or roommate change, new locks provide peace of mind. Our technicians can assess your current setup and recommend whether rekeying or a full lock change best serves your needs.
Residential Lock Change
Protecting your home starts with reliable entry locks. Code Locksmith specializes in residential lock change services for single-family homes, condos, townhouses, and apartments across Los Angeles. We replace doorknob locksets, deadbolts, and handle multipoint locks on sliding glass doors. Whether you need one front door lock changed or every entry point upgraded, our mobile technicians complete the work on-site with minimal disruption. We ensure proper alignment, smooth operation, and a secure fit for every installation. Many Los Angeles homeowners choose to upgrade from basic builder-grade locks to Grade 1 or Grade 2 deadbolts for maximum protection against forced entry.
Commercial Lock Change
Business security demands robust locking systems. Our commercial lock change services cover offices, retail stores, warehouses, and multi-tenant buildings throughout Los Angeles. We replace mortise locks, cylindrical locks, panic bars, and high-security commercial grade hardware. When employees leave, keys go missing, or you're rebranding a space, a commercial lock change ensures only authorized personnel retain access. Code Locksmith works with property managers and business owners to schedule lock replacements with minimal downtime. We also install master key systems so you can maintain control over multiple doors while providing individual keys to specific areas.
Deadbolt Upgrade
Deadbolts offer significantly stronger resistance against forced entry compared to spring-latch locks. Upgrading to a deadbolt is one of the most effective security improvements you can make. Code Locksmith installs single-cylinder deadbolts (key outside, thumb turn inside) for standard doors, and double-cylinder deadbolts for doors with glass panels within reach of the lock. We carry Grade 1 and Grade 2 deadbolts—the highest ANSI ratings for residential and commercial use. Our technicians ensure correct backset measurement, proper hole boring when needed, and a flush strike plate installation for a solid, reliable lock. Many older Los Angeles homes lack deadbolts entirely; we can add them to any exterior door.
High-Security Lock Installation
For maximum protection, high-security locks add layers of resistance against picking, drilling, bumping, and physical attack. Brands like Medeco, Mul-T-Lock, and ASSA Abloy offer hardened steel components, restricted keyways, and advanced pin designs. Code Locksmith installs high-security locks for residential and commercial clients who need extra peace of mind. These locks are ideal for homes with valuable belongings, businesses handling sensitive data, or anyone who has experienced a previous break-in attempt. While high-security locks cost more upfront, they provide long-term value through superior durability and enhanced resistance. We'll explain the differences between brands and help you choose the right level of security for your situation.
