What Does Rekeying Mean?
Rekeying is the process of changing the internal mechanism of a lock so that the old keys no longer work. A locksmith removes the cylinder, replaces the internal pins with a new configuration, and cuts fresh keys to match. The existing lock hardware stays in place.
Rekeying is a good option when the locks are in good condition and you simply want to ensure that old keys stop working. It is usually cheaper and faster than replacing the hardware, and it preserves the appearance and finish of your existing doors. For many new homeowners, rekeying is the simplest and most practical first step.
What Does Lock Replacement Mean?
Lock replacement means removing the old hardware entirely and installing new locks, deadbolts, or smart locks. This is a more involved process than rekeying, and it changes both the security and the appearance of your entryways.
Replacement makes sense when the existing locks are old, damaged, weak, or outdated. It is also the right choice if you want to upgrade to smart locks, high-security locks, or hardware that matches the style of your new home. Replacement can improve both physical security and everyday convenience, but it costs more and takes longer than a simple rekey.

When Rekeying Is Enough
Rekeying is often sufficient for a new home, especially if the existing locks are in decent shape. Consider rekeying if:
- Locks in Good Condition
The locks are in good condition and function smoothly.
- Like Current Hardware
You like the current hardware and want to keep it.
- Invalidating Old Keys
Your main goal is to make old keys stop working.
- One-Key Convenience
You want one key to open multiple compatible locks.
- No Signs of Damage
There are no signs of damage, looseness, or weakness.
- Budget-Friendly Step
You want a budget-conscious security step before making bigger upgrades.
In these cases, a home rekey service gives you full control over access without the expense of new hardware.
When You Should Replace the Locks
Sometimes rekeying is not enough, and replacement is the better investment. Consider replacing the locks if:
- The lock is old, worn, or difficult to operate
- The lock sticks, jams, or requires jiggling to work
- The deadbolt does not align properly with the strike plate
- The hardware is visibly damaged or loose
- You want to install smart locks or keypad access
- You want high-security locks with controlled key duplication
- There was a break-in or attempted break-in at the property
- The locks throughout the house are mismatched or inconsistent
In these situations, replacement improves both security and reliability. A residential locksmith in Indianapolis can assess each lock and tell you which ones can be rekeyed and which should be replaced.
