The Hidden Dangers of Duplicate Keys – Who Really Has Access to Your Home?

Most homeowners assume they are the only ones with keys to their home—but are you really sure? Duplicate keys are more common than you think, and they can pose a serious security risk if not properly managed. At C and J Lock, we’ve seen firsthand how unauthorized copies can lead to break-ins and security breaches. Here’s what you need to know about the hidden dangers of duplicate keys and how to protect yourself.

How Easy Is It to Duplicate a Key?

Many standard house keys can be copied in minutes at a hardware store, locksmith shop, or even self-service kiosks. Some key duplication services don’t require proof of ownership, meaning anyone who gets their hands on your key—even for a short time—can make a copy without your knowledge.

Who Might Have a Copy of Your Key?

🔑 Previous Homeowners or Tenants – If you’ve recently moved in, you have no way of knowing how many copies exist or who might still have access.
🔑 Contractors & Cleaners – Did you ever lend a key to a repair person, house cleaner, or babysitter? Even if they returned it, there’s no guarantee they didn’t make a copy.
🔑 Neighbors & Friends – If you’ve ever given a spare key to a friend or neighbor, are you sure they haven’t passed it along to someone else?
🔑 Landlords or Property Managers – If you rent, your landlord or management company likely has access, but do you know how many copies exist?

How to Take Control of Your Home Security

✅ Rekey Your Locks When You Move In – This ensures that any old keys will no longer work, giving you full control over access to your home.
✅ Use High-Security, Copy-Protected Keys – These keys can only be duplicated by an authorized locksmith with proper verification.
✅ Consider Smart Locks – Keyless entry eliminates the risk of physical key copies altogether.
✅ Keep Track of Your Keys – If you must lend out a key, be selective about who gets it and retrieve it as soon as possible.
