Rekey or Replace? How to Decide After You Move Into a New Home

Moving into a home that someone else lived in means you don’t know who still has a key. Previous owners, contractors, dog walkers and neighbors may all have copies. The fix is simple, but you have two options: rekey the locks or replace them.

When rekeying makes sense

If your locks work smoothly and you like how they look, rekeying is usually the cheaper choice. A locksmith changes the small pins inside the cylinder so old keys stop working and a new key does. The hardware stays on the door. It’s also the easiest way to get every exterior lock working on one key.

When replacing makes sense

Replace the lock if it’s worn, sticky, cheaply made or damaged, or if you want an upgrade like a heavier deadbolt or a keypad. A lock change also lets you match finishes across the house.

A quick checklist

• Does the key turn smoothly? If yes, rekey.
• Is the deadbolt a solid brand with a full 1-inch throw? If yes, rekey.
• Is anything loose, rusted or damaged? Replace.
• Want smart or keypad access? Replace.
