How to Dispose of Keys?

Here are the top 5 ways to dispose of keys:

1. Give your extra keys to a friend

In an emergency, having a spare set of keys is always a good belief. Whether you are locked out of your house or car or need to give someone access to your home in your absence, having an extra set of keys can be a lifesaver.

If you have unused keys, consider giving them to a friend or family member who can keep them safe for you. That way, if you ever find yourself in a bind, you know that help is just a phone call away.

If you no longer need a particular set of keys, securely dispose of them so that they cannot be used by anyone else. By taking these simple precautions, you can rest assured that you will always have access to the things and people that matter most to you.

2. Leave your keys with your landlord

One of the scariest things that can happen is to lose your keys. Not only are you locked out of your home, but you also have to worry that someone else will find it and gain access to your property. However, there is a simple solution to this problem: leave an extra key with your landlord or property manager.

If you ever lose your keys, you can easily call them and ask for a replacement. Additionally, discard any old keys that you no longer need. It will prevent them from falling into the wrong hands and ensure that your home is safe.

3. Mail them back to the lock company 

If you have a bunch of old keys, don’t just throw them away in the trash. Send them back to the lock company so they can recycle the metal. It’s an easy way to be more eco-friendly, and you’ll be freeing up some space in your home simultaneously.

Just be sure to include a note stating to the company what you are doing so that they can properly dispose of the keys.

4. Drop them off at a local locksmith 

Most people don’t think twice about what to do with an old key. They can throw it in the trash if it is no longer needed. However, the keys are a precious resource made of metal. And when the keys begin to settle in the landfill, the metal can seep into the ground. And contaminate the soil and water.

A better way to dispose of keys is to leave them in a local locker. There, the metal can be melted down and reused. Not only does this help protect resources, but it also keeps harmful metals away from the environment.

So the next time you have an old key, don’t throw it away – recycle it instead.


Whether you recycle your old keys or give them to someone else, it is important to take precautions to ensure that your home is as secure as possible. Please ensure you always have a safe place, such as your landlord or property manager, with a key safe, and wrap any extra keys, so they don’t get lost.
