A residential locksmith is a professional who specializes in securing homes through lock installation, repair, rekeying, and lockout assistance. LT Lock and Key offers a full range of residential locksmith services across San Diego County, including:

When you buy a new home, the previous owners may still have keys. Rekeying the locks is one of the first steps every new homeowner should take to feel truly secure.
Commercial Locksmith Services
Businesses have different security needs than homes. LT Lock and Key provides commercial locksmith services that cover office buildings, retail shops, restaurants, and multi-tenant properties throughout San Diego County. Services include:
- Commercial lock installation and repair
- Door hardware replacement
- Master rekeying for multi-door buildings
- File cabinet lock replacement and decoding
- Panic bar and exit device service
Master rekeying is a system that allows a single master key to open multiple locks while each lock also has its own unique key. This is ideal for property managers and business owners who need tiered access control.
Rekeying vs. Replacing Locks: Which Do You Need?
One of the most common questions homeowners and tenants ask is whether they should rekey or fully replace their locks. Rekeying is a process where the internal pins of an existing lock are changed so that a new key operates it. It is faster and more affordable than full replacement.
Full lock replacement makes sense when hardware is visibly damaged, outdated, or you want to upgrade to a higher-security or smart lock system. According to the U.S. Bureau of Labor Statistics, demand for skilled locksmiths continues to grow alongside the expansion of electronic security systems.
