One of the most common questions we get at Seatown Locksmith is: should I rekey my locks or replace them entirely? The answer depends on your situation — and in most cases, rekeying is all you need.
What Is Rekeying?
Every pin tumbler lock contains a set of small spring-loaded pins configured to match your key. When a locksmith rekeys your lock, they disassemble the cylinder and replace the pins with a new set that matches a new key — leaving all the hardware in place. Your old key no longer works. A new key does.
When to Rekey
- Moving into a new home — you don't know who has copies of existing keys
- Lost or stolen keys — faster and cheaper than replacing the lock
- Ended a tenancy — tenants may have made copies without telling you
- Employee or contractor access revoked
- Want all locks on one key — a locksmith can rekey multiple locks to the same key
When to Replace
- Lock is damaged or heavily worn
- After a break-in where the lock was forced
- Upgrading to a higher security grade
- Installing a smart lock — most replace the deadbolt entirely
The Bottom Line on Cost
Rekeying a single lock typically costs $20–$50. Replacing a lock costs $80–$300+. For most situations — a new home, lost key, or access revocation — rekeying gives you the same protection at a fraction of the cost. Call Seatown Locksmith at (206) 420-3426 for a same-day rekeying quote.
