Here’s a detailed breakdown to help you decide whether to replace or rekey your locks:

🔑 Rekeying Your Locks

Rekeying involves changing the internal pins and tumblers of a lock so that it works with a new key, while keeping the existing lock hardware.

✅ When to Rekey

• You’ve moved into a new home and want to ensure previous owners or contractors can’t access it.

• You’ve lost a key and are concerned someone might find and use it.

• You want all locks to use the same key, provided they are compatible (same brand/type).

• You’re changing access for service providers (e.g., cleaners, babysitters).

• Your locks are in good condition, and you want a cost-effective security refresh.

💰 Cost

• Typically $50–$100 per lock, mostly for labor.

• DIY kits are available for $10–$25, but require the correct brand and some skill.

👍 Pros

• More affordable than replacing.

• Quick and minimally invasive.

• Maintains existing hardware aesthetics.

👎 Cons

• Doesn’t upgrade the lock’s security level.

• Not possible if the lock is damaged or you don’t have the original key.

🔒 Replacing Your Locks

Replacing means removing the entire lock and installing a new one, often with different features or improved security.

✅ When to Replace

• Your lock is damaged, worn, or broken.

• You want to upgrade to a smart or keyless system.

• You’re remodeling and want a new look.

• You want higher security features (e.g., bump-proof, pick-resistant).

• You don’t have the original key, and rekeying isn’t feasible.

💰 Cost

• Around $75 per hour for labor, plus the cost of the lock hardware (average total ~$315).

👍 Pros

• Allows full customization and upgrades.

• Enhances security with modern features.

• Matches new home design or aesthetic.

👎 Cons

• More expensive and time-consuming.

• May require door modifications for compatibility.
