How to Re-key a Door Lock

Re-keying a Door

Have you ever lost your house keys and worried about a stranger getting in? Unless you’re the first occupant of the property, you never can be sure how many copies of your keys exist. Locksmiths typically charge a fee to re-key an individual lock, even when you bring it to their shop. Since most homes have multiple doors with multiple locks, re-keying can get expensive.

You can re-key a lock like a pro at a fraction of the cost. Re-keying kits are available for most lock brands but they’re not interchangeable. You must buy a kit for each brand of lock in your home. (If you’re lucky, they’ll all be the same brand!)

Each kit will re-key six locks, but you can order extra pins if you need to do more. The kit will work on entrance and deadbolt locks, and it comes with two keys and all the tools you’ll need except a screwdriver. But keep your current keys — you’ll need them to remove the cylinder.

We used a Schlage brand lock for this story. If you have a different brand, check your instruction sheet for minor variations.
