You have lost your keys. Or perhaps a tenant has just moved out and you are unsure how many copies are still in circulation. The first reaction is often to replace the entire lock. However, there is a smarter and often more affordable solution: rekeying.

Many people have heard the term but do not fully understand what it involves. Rekeying does not mean replacing the whole lock. It means adjusting the internal mechanism so the old key no longer works. A locksmith resets the pins inside the lock cylinder and supplies a new set of keys. The door, handle, and lock remain unchanged. Only the key is different.

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 Delft, 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 If the mechanism is damaged, outdated, or insecure, it’s time for a full replacement.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 Delft, or just as easily when you call us in The Hague.

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.
