Last Updated on March 16, 2024 by Vincent Zhu

Have you ever wondered what to do with old hotel key cards? Whether they’ve somehow ended up in your bag post-vacation or you’ve collected them over years of travel, these cards can pile up.

Instead of discarding them and contributing to waste, there are numerous innovative and responsible ways to use old hotel key cards. This guide provides creative ideas and sustainable practices for handling your collection of old hotel key cards.

Hotel key cards are often made of plastic, so they should ideally be recycled properly. However, not all recycling programs accept these types of plastic, so it’s important to check with your local recycling center first.

But here, we have some great ideas to help you repurpose hotel key cards:

Return hotel key card

Returning a hotel key card is a simple process:

  1. Please give it to the front desk. After check-out, you can hand the key cards to the staff. They will take care of deactivating and reusing or recycling them. Then, the next hotel guest can keep using this key card to open hotel locks.
  2. Leave it in a drop-off box: Some hotels have a Hotel key card drop-off box or hotel key card collection at the front desk where you can leave your key card if there’s a queue or check-out outside the front desk’s operating hours.
  3. Leave it in the hotel room: You can leave the key card in your room when you check out. However, it’s best to ask the hotel staff about their preferred method to ensure the card is accounted for.

Remember, while most hotels do not charge for unreturned cards, it’s always polite and eco-friendly to return them if you can.

Hotel key card art

Art can be made from almost anything, and hotel key cards are no exception. They are a great size and shape for various types of artwork, and if you travel a lot, they can be a fun way to remember different places you’ve been. Here are a few hotel key card car ideas:

  1. Mosaic Art: You can cut the cards into small pieces and use them to create colorful mosaic designs. This could be on a small scale, like a coaster or picture frame, or on a larger scale, like a tabletop or wall art.
  2. Collage: Combine hotel key cards with other materials to create a collage. This could be a great way to display your travel memories. You could use the actual cards or them as a base and layer other materials on top.
  3. Jewelry: You can cut and shape hotel key cards into interesting designs to make unique jewelry pieces. You might need additional materials and tools to shape the plastic, like a hole punch, jewelry findings, and possibly a heat tool.
  4. Painting Tools: Hotel key cards can also be used to create art. They’re great for scraping paint to create interesting textures and patterns on a canvas.
  5. Mixed Media Art: Incorporate hotel key cards into mixed media art pieces. They can be painted, collaged, stacked, layered, or altered to become part of a larger work.
  6. Sculpture: If you have many of them, you could use them to create a three-dimensional sculpture.

Remember that if you cut or heat the cards, do so in a well-ventilated area and be careful not to hurt yourself. And, of course, have fun with your creativity!

Hotel key card display

Displaying your collection of hotel key cards can be a great way to remember your travels and add a unique decorative touch to your space. Here are a few ideas on how you can display your hotel key cards:

  1. Shadow Box: Arrange your hotel key cards in a shadow box and hang it on the wall. You can arrange them by color, location, or date to create a visual story of your travels.
  2. Bulletin Board: Pin your hotel key cards onto a bulletin board. This allows you to add new cards as you collect them easily.
  3. Photo Album: Use a photo album or a business card album to store and display your cards. This keeps them protected while allowing you to flip through and view them.
  4. Picture Frame: If you have a smaller collection, consider arranging them in a large picture frame. You can use a background that complements the colors of the cards.
  5. Map Display: If you have hotel key cards from different locations, consider displaying them on a map. You can pin the cards to their corresponding location using a corkboard map.
  6. Glass Jar: Place your hotel key cards in a glass jar or vase for a simple and casual display. This can be an interesting decorative item on a bookshelf or table.
  7. Scrapbook: If you enjoy scrapbooking, consider creating a scrapbook for your hotel key cards. You can add photos, ticket stubs, and other travel souvenirs.

When creating your display, consider writing the date and location on each card (if it’s not already printed) to help you remember where each one came from.

Destroy them

Suppose you’re concerned about potential unauthorized use (though it’s unlikely, as most key cards don’t store personal data and are typically deactivated upon check-out). In that case, you might want to destroy them physically. Use scissors to cut them up, or run them through a shredder if you can access one.

Reprogram hotel key card

Depending on their condition and technology, old hotel key cards can be repurposed or responsibly disposed of in several ways. Reprogramming them for further use within the hotel industry is one common approach, alongside recycling and creative repurposing. Here’s a closer look at what can be done:

  • Within the Same Hotel: Many hotels can reprogram key cards for new guests, making the most practical and eco-friendly option reusing them. This process involves reencoding the magnetic stripe or reprogramming the RFID (Radio-Frequency Identification) chip with new access permissions for a different room or set of rooms, effectively resetting the key card for a new guest.
  • Other Applications: Beyond hotel room access, old key cards can sometimes be reprogrammed for different purposes, such as access control to hotel amenities (gyms, pools, etc.), parking garages, or even as part of loyalty or discount programs. However, this requires compatible systems and the technical capability to reencode or reprogram the card.

Can you keep hotel key cards?

Yes, you can typically keep your hotel key cards. Most hotels use reprogrammable RFID cards to open RFID hotel locks, so they don’t mind if guests take them as souvenirs or forget to return them. However, these cards hold no value outside of the hotel, and once deactivated, they cannot be used for future access.

Remember that some high-end hotels or resorts might use more expensive, proprietary key systems or cards and charge a fee if the hotel key cards are lost or not returned. If you’re unsure about their policy, checking with the front desk is always a good idea.

Do Hotel Key Cards Contain Personal Information?

Typically, hotel key cards do not contain any personal information. They usually contain the room number and the dates of your stay, encoded so the door lock mechanism can read them.

This means that even if someone else found your lost key card, they could not access your personal or financial information. This is why the risk of identity theft from a lost hotel key card is generally considered low.

However, to ensure the safety of your belongings, you should still report the lost key card to the hotel as soon as possible so they can deactivate it and prevent anyone else from using it to access your room.

Are hotel key cards recyclable?

Yes, hotel key cards can be recyclable, but it depends on the material they are made from. Key cards made from PVC (polyvinyl chloride) are technically recyclable, but not all recycling facilities accept them due to the specific processing required.

Cards made from eco-friendly materials like wood, bamboo, or bioplastics are more readily recyclable. Hotels need to work with recycling programs that can properly process these items.

Despite the potential for recycling, recycling hotel key cards is not as common as it could be. Many hotels do not have programs to collect and recycle used key cards, and guests may not know how to dispose of them properly.

Do you have to return hotel key cards?

While it’s generally considered good etiquette to return hotel key cards to the front desk upon checking out, it’s not typically required. Most hotels use disposable or reprogrammable key cards, which can be easily and inexpensively replaced.

However, some hotels, especially luxury or boutique establishments, may use more expensive key systems or cards and charge a fee if the card isn’t returned. If unsure, it’s always best to ask the hotel staff about their policy.

In the past, there was also some concern about personal data being stored on these cards, but this is largely a myth. Modern hotel key cards don’t typically store sensitive information beyond an encrypted link to your reservation in the hotel’s system, which is deactivated after you check out.

What happens if you take a hotel key card?

If you take a hotel key card and forget to return it upon check-out, typically, nothing happens. Most hotels expect a certain percentage of key cards not to be returned. They use key cards that are inexpensive to replace and easy to reprogram for the next guest.

However, some high-end hotels or resorts that use more expensive, proprietary key systems might charge a fee to your account if the key is not returned. This is not the norm, but it can occur.

Remember, a hotel key card has no value outside of your stay at the hotel. Once you check out, the key card is deactivated and will not grant access to any room. If you’ve accidentally taken a key card, you can mail it back to the hotel or return it on your next visit.

Do hotels reuse key cards?

Yes, many hotels do reuse key cards. Once guests check out, the cards are often collected, cleaned, and reprogrammed for future guests. This is cost-effective for the hotel and a more environmentally friendly practice.

However, not all hotels have this policy, and some might not ask for the cards to be returned upon check-out. In these cases, guests may take them home as souvenirs or dispose of the cards.

If you’re concerned about waste, the best thing you can do is to return your key card to the front desk at check-out. That way, if the hotel does have a reuse policy, they can implement it. If not, you’ve done your part to reduce potential waste.

Conclusion

Old hotel key cards don’t have to end up in the trash. With a little creativity and a commitment to sustainability, you can give them a second life or ensure they’re disposed of responsibly.

Whether you repurpose them into useful items, use them for art projects, or return them to the hotel for recycling, you can make a positive impact. The next time you find an old hotel key card in your luggage, you’ll know exactly what to do!

FAQs About What to Do With Old Hotel Key Cards


Taking a hotel key card is not generally considered illegal. Most hotels understand that guests might inadvertently take key cards with them upon checkout, and they factor the cost of replacement cards into their operating expenses.

However, if a hotel clearly states that guests will be charged for unreturned keys and you take one without intending to pay, there could be legal implications, although rare.

Moreover, if a hotel uses more expensive, non-disposable keys or key fobs, there may be a stated fee for lost or unreturned keys. In such cases, taking the key without paying the fee could be considered theft.

In any case, it’s always a good idea to return your hotel key card upon checkout. If you forget, the best thing to do is contact the hotel, explain the situation, and ask how they would like you to proceed.


You can usually keep your hotel key card as a souvenir. They’re generally inexpensive for hotels to replace. However, if you’re staying at a high-end hotel with more expensive key cards, it’s a good idea to ask first.


 If you’ve accidentally taken a hotel key card, you can either keep it, return it on your next visit or mail it back to the hotel, depending on your preference and the hotel’s policy. If you’re unsure, call the hotel to ask what they prefer.



While rare, some hotels may charge a fee for unreturned key cards, particularly if they use more expensive or non-disposable types. This policy should be outlined in the hotel’s terms and conditions. When in doubt, ask the hotel staff.
