How to Rekey Your Locks After Moving Into a New Home

Learn when and how to rekey locks after moving with guidance from Morayfield Locksmiths. Protect your new home with professional rekeying services in the Moreton Bay region.

Moving into a new home is exciting, but you cannot know how many keys exist or who might have copies from previous owners, contractors, or real estate agents.

1. Understand Rekeying vs. Lock Replacement

Rekeying involves changing the internal pins in your existing locks so old keys no longer work, while replacement installs entirely new locks. Rekeying costs significantly less than replacement when your current locks function properly and meet your security needs. Most standard pin-tumbler locks can be rekeyed multiple times throughout their lifespan. However, if your locks are damaged, outdated, or low-quality, replacement provides better long-term value. At Morayfield Locksmiths, we honestly assess whether rekeying or replacement serves your situation best, considering both security and budget.

2. Inventory All Locks Requiring Rekeying

Walk through your property identifying every exterior lock, including front and back doors, garage entries, gate locks, shed locks, and any other access points. Interior doors typically do not require rekeying unless they secure valuable items or private areas. Note the brand and type of each lock, as some brands use proprietary keyways that require specific blanks. This inventory helps your locksmith provide accurate quotes and ensures no locks are overlooked during service.

3. Decide Between Matching Keys or Separate Systems

You can rekey all locks to operate on a single key for convenience, or maintain separate keys for different areas. Single-key systems are popular for residential properties, eliminating the frustration of managing multiple keys. However, some homeowners prefer different keys for exterior and interior spaces, or separate keys for main residence and detached structures like workshops. Consider your household size and whether multiple family members need access to all areas when making this decision.

4. Schedule Professional Rekeying Service

While DIY rekeying kits exist, professional service ensures correct installation and consistent operation across all locks. Improper rekeying can damage lock cylinders or create keys that stick or fail to operate smoothly. Professional locksmiths complete the work efficiently, typically rekeying multiple locks in a single visit. We carry extensive pin kit inventories allowing us to rekey virtually any standard lock immediately, without requiring return visits for special orders.

5. Test All New Keys Thoroughly

After rekeying, test each new key in every lock multiple times before your locksmith departs. Verify that keys insert and turn smoothly without resistance, and that deadbolts extend fully. Test that old keys no longer operate the locks, confirming the rekeying was successful. Request several copies of your new keys rather than having cheap duplicates cut later at hardware stores, as professionally cut keys from quality blanks provide more reliable long-term operation.

6. Secure Your New Keys Appropriately

Label keys clearly so household members know which key operates which lock, but avoid labels that identify your address if keys are lost. Store spare keys securely, such as in a safe or with a trusted neighbor, rather than under doormats or in fake rocks that burglars routinely check. Consider giving one copy to a trusted emergency contact living nearby who can assist if you are locked out. Never leave spare keys hidden outdoors, as this negates the security improvement rekeying provides.
