You’ve lost your keys. Or maybe your tenant just moved out, and you’re not sure how many copies are still floating around. The gut reaction? Replace the lock. But there’s a smarter, often cheaper option: rekeying.

Most people have heard the term but don’t really know what it means. Rekeying doesn’t mean changing your entire lock, it means changing the internal mechanism so that your old key no longer works. A locksmith resets the pins inside your lock cylinder and provides you with a brand-new set of keys. That’s it. Your door, handle, and lock stay exactly the same. Only the key changes.

Why Rekeying Is Often the Better Choice

If your lock is in good shape, and you’re simply concerned about who might have access, rekeying is a clean, cost-effective solution. You get peace of mind without the cost or hassle of a full replacement. It’s perfect for situations like moving into a new home, changing roommates, or even after a break-up. At Locksmith 365, we rekey all major lock brands, often in under 30 minutes, and we do it right at your doorstep. 

When Replacement Still Makes More Sense

Rekeying only works if the existing lock is functioning properly. If the mechanism is damaged, outdated, or insecure, it’s time for a full replacement. Think of it this way: rekeying gives you control over who has access. Replacing gives you better control over how they get in. 

For example, if your lock doesn’t meet current security standards, or if it’s starting to stick, replacing might be the safer bet. In those cases, we can advise you on options during an emergency locksmith call in Rotterdam, or just as easily when you call us in Delft.

Rekeying Is Quick, Clean, and Budget-Friendly

People often assume rekeying is a major job, but it’s usually done in less than half an hour. There’s no drilling, no need to remove the entire lock system, and no damage to the door or frame. You simply get a new key, and the old one no longer works. Simple as that. If you want to learn more or schedule a visit, just contact us and we’ll guide you through your options.
