Frequently Asked Questions

Rekeying changes the internal pins inside the lock cylinder so old keys no longer work, while the lock hardware stays in place. A locksmith replaces the pins to match a new key, restoring security without full replacement. At A-Best Locksmith, we walk customers through how rekeying works and when it's the best option.

Rekeying is ideal when the lock hardware is still in good condition but you need to change who has access—like after moving in, tenant turnover, or losing keys. It's more cost-effective than replacing the entire lock. At A-Best Locksmith, we provide honest recommendations based on lock condition and your security needs.

Deadbolts can fail due to internal wear, misaligned doors, latch strikes that don't line up, or broken internal springs. Sometimes the door frame shifts over time, making the bolt hard to turn or lock. At A-Best Locksmith, we diagnose the root cause and explain whether repair or replacement makes the most sense.

High-security keys use restricted keyways and special designs that prevent unauthorized duplication at typical hardware stores. Standard keys can be copied anywhere, which weakens access control. At A-Best Locksmith, we explain whether a non-duplicatable system is worth it based on your home or business security goals.

Many sticky locks can be repaired by addressing door alignment, worn pins, or latch issues rather than replacing the entire lock. A full diagnosis reveals whether internal wear or misalignment is the real problem. At A-Best Locksmith, we tell you what failed, why, and what was done to restore smooth operation.

New homeowners should rekey or replace all exterior locks since previous owners, contractors, or tenants may still have keys.

A master key system creates tiered access, allowing some keys to open specific doors while a master key opens all locks in the system.
