Moving Into a New Home? Why Rekeying Your Locks Should Be Your First Step

December 5, 2025

Moving into a new home comes with a mix of excitement and responsibility. You finally get the keys, step through the door, and start imagining how you will settle in. It feels like a fresh start. But there is one thing many new homeowners overlook in those first few days. The keys you just received may not be the only copies that exist.


Previous owners might have shared spare keys with neighbors, babysitters, contractors, cleaners, or family members. Real estate agents or maintenance crews may have had access as well. Even if everyone was trustworthy, there is no way to know how many keys were made or where they ended up. That uncertainty can leave you feeling uneasy, especially when you realize anyone with an old copy could walk right in.

This simple detail creates a real problem. You cannot be fully confident in your home’s security until you take control of the locks. That is why rekeying should be the first step on your move-in checklist.


The Hidden Risk New Homeowners Often Miss

Imagine the first night in your new place. You lock the door, turn off the lights, and finally lie down after a long day of unpacking. You expect to feel settled, but your mind drifts to the locks on the doors. You did not install them. You do not know their history. You have no idea how many keys exist.

This moment is more common than most people realize. Many homeowners assume that getting the keys at closing means they are the only ones who have them. But the truth is that door locks hold their history unless you take action. Rekeying clears that history and gives you a fresh start.


How Rekeying Protects Your New Home Right Away

Rekeying is the process of changing the internal pins inside a lock so it works with a new key. The exterior hardware stays the same, and the old keys stop working immediately. It is one of the fastest and most cost-effective ways to secure your home after moving in.


A locksmith removes the cylinder, replaces the pins, cuts a matching key, and tests the lock to ensure everything operates smoothly. The entire process can be done on all main entry points, often within the same visit. Many homeowners also choose to have the house rekeyed to one single key (when compatible hardware is in place, or replacing locks with compatible ones if they aren’t already to do so) , which simplifies access and eliminates the confusion of juggling multiple different keys.


Rekeying works best when done before you settle in. It removes the risk of unknown access and helps you begin your time in your home with confidence. It is also helpful if the previous owner left behind worn keys or if multiple locks were keyed differently. A professional locksmith can make everything consistent, secure, and easy to use.


This simple step belongs at the very top of your move-in checklist. It protects your belongings from day one and gives you peace of mind each night that follows.


Rekeying vs. Changing Locks: Which to Choose?

Many homeowners wonder whether they should change the locks entirely instead of rekeying them. In most cases, rekeying is the more practical solution. It is faster, less expensive, and achieves the same result when the existing lock hardware is still in good shape.

Changing the locks makes sense in specific situations, such as:


  • The locks are damaged or sticking
  • The hardware is outdated or low quality
  • You want to upgrade to a different style or higher security level


A residential locksmith can evaluate your doors and recommend the best approach. For most new homeowners, rekeying offers the perfect balance of safety and affordability.

What to Expect During a Professional Rekeying

The process is straightforward when handled by a professional:


  1. The locksmith examines your existing locks.
  2. The lock cylinder is removed and the pins inside are replaced.
  3. A new key is cut to match the updated pin configuration.
  4. The lock is reassembled and tested for smooth operation.
  5. Multiple locks can be matched to a single key if desired (when compatible).


Most rekeying jobs are completed quickly. The cost to rekey locks depends on the number of locks, their condition, and whether you want them all keyed alike. It is a small investment for the level of security you gain.

Why Professional Rekeying Is the Safer Choice

Rekeying might appear simple, but precision matters. A professional locksmith ensures the job is done correctly, so that old keys cannot operate the lock. This prevents unexpected access and helps preserve the lifespan of your hardware.


A locksmith can also identify issues that a DIY approach might miss, such as worn mechanisms, misaligned strike plates or malfunctioning hardware. Fixing these small problems improves both security and convenience.
