What Is Rekeying?
Rekeying is the process of changing the internal pin configuration of your existing lock so that old keys no longer work and new keys are created. The lock hardware itself stays the same — only the internal mechanism changes. This is a quick, cost-effective process that a professional locksmith can complete in about 15-20 minutes per lock. Rekeying typically costs $15-$35 per lock, compared to $75-$300+ for a full lock replacement.
When to Rekey Your Locks
Rekeying is the right choice when: you've just moved into a new home (you don't know who has copies of the old keys), you've lost a key or had one stolen, an employee or roommate has moved out, you want all your locks to use the same key (master keying), or after a domestic dispute where one party should no longer have access. Rekeying is also ideal when your lock hardware is in good condition and you're happy with the security level it provides.
When to Replace Your Locks
Full lock replacement is necessary when: your locks are old, worn, or damaged, you want to upgrade to a higher security grade, you're switching to smart locks or electronic locks, your locks don't meet insurance requirements, after a break-in where the lock was damaged, or when you want a completely different style or finish. If your locks are more than 10-15 years old, replacement is usually a better investment than rekeying.
Cost Comparison
For a typical Los Angeles home with 3-4 exterior doors: Rekeying all locks costs approximately $60-$140 total. Replacing all locks with Grade 2 deadbolts costs approximately $300-$800 total. Upgrading to smart locks costs approximately $600-$1,200 total. Rekeying is clearly the budget-friendly option when your existing hardware is in good condition. However, if your locks are outdated or you want enhanced security features, replacement provides better long-term value.
