Rekeying a lock is an essential service that ensures your security, whether you’ve moved into a new home, lost your keys, or want to prevent access from someone who previously had a key. If you’re wondering how long this process takes or if it’s something you can do yourself, you’re in the right place. This guide covers every aspect of lock rekeying, from the time it takes to the steps involved and DIY considerations.
5 Reasons Why Rekeying is Better Than Replacing Your Locks
Rekeying a lock involves changing the internal pins and tumblers so that an old key no longer works. Instead, a new key is created to match the modified lock mechanism. Unlike replacing the entire lock, rekeying is a cost-effective way to enhance security without significant hardware changes.
When moving, rekeying ensures previous residents or anyone with an old key can no longer access your home.
Losing keys or having them stolen poses a security risk. Rekeying ensures unauthorized individuals cannot use the old keys.
Rekeying allows you to standardize locks, enabling one key to open multiple doors, simplifying access without compromising security.
A professional locksmith typically takes 15-30 minutes to rekey a single lock. The exact time depends on the lock type and the locksmith’s experience.
Rekeying multiple locks to the same key can take 30 minutes to an hour, depending on the number of locks and their complexity.
If you choose the DIY route, expect to spend 30 minutes to an hour per lock, especially if it’s your first time. Gathering tools, reading instructions, and troubleshooting may extend the process.
