Rekeying a lock to match an existing key means changing the internal pins so the old key operates the new lock. The specific method depends entirely on the lock's brand and whether your new lock utilizes smart rekeying technology or requires a physical pin kit.
To change a lock so that it fits an existing key, you simply work in the opposite direction: You change the pattern of the pins in the lock so that it matches the pattern of notches in the key. If the lock is designed with a universal keying system, any locksmith can re-key the lock in no time.
You'll need a rekeying kit that matches your lock brand, along with basic tools like a screwdriver, plug follower, and tweezers. Follow a simple process: remove the lock, replace old pins with new ones matched to your key, then reassemble.
However, you can still get multiple locks set to a single key, whether you're replacing all the locks on your property or just replacing a few: Some locks have a feature that allows you to rekey them to a specific key yourself. You can get locks professionally rekeyed.
To make all your locks work with the same key (often called "keying alike"), you can either use specialized rekeyable locks, buy a DIY rekeying kit, or take your lock cylinders to a local locksmith or hardware store.
When you change a lock, you or a locksmith will replace the old locking door hardware, giving you all new locks and all new keys. But changing your locks is usually more expensive than rekeying, and it isn't always necessary.

I called Lowe's and they will re-key locks for free, but I have to buy all new locks from Lowe's (about $50-100 per lock depending on the type) and install them myself. However, I'm not very handy and don't have the tools at home to install them. We also need a new deadbolt for one of the doors.
Rekeying is generally the lowest-cost way to secure your home. Most lock-updating services cost around $15–$50 per cylinder, depending on the number of locks and whether you already have an existing key.
Most standard locks can be rekeyed, but not all of them. Locks with pin-and-tumbler cylinders, deadbolts, and knob locks are commonly rekeyed. However, keyless locks, damaged locks, and those without removable cylinders cannot be rekeyed.
A traditional pin tumbler lock can be rekeyed multiple times, practically as long as the internal components remain in good working condition. There is no strict numerical limit; it is limited by the physical wear of the lock cylinder itself, not the act of rekeying. Special "SmartKey" locks can be rekeyed an unlimited number of times.
To get keyed alike locks, you can purchase sets with the same key code, special order them from home improvement stores, or use rekeying kits to match existing locks. Keyed-alike locks, which allow multiple locks to be operated by a single key, can also be ordered online for convenience.

A sock on a doorknob is a traditional signal—mostly used by college students or roommates—that the person inside the room is having sex and needs privacy. It acts as a makeshift "do not disturb" sign to prevent roommates from walking in.
