Magnets=bad when it comes to magnetic strips. This started the urban legend, in my opinion. If you Google cell phone and hotel key, there are a lot of people saying that electromagnetic fields erase data on a magnetic strip. It can't, and I can prove it!

In conclusion, phones do not deactivate hotel room keys. This myth likely originated from a misunderstanding of how hotel keys work.
Not a good idea. In most cases, when you get to front desk, they will ask you to bring the key. Most hotels though no longer uses keys but they use key cards (which is controlled by front office), so where you have leave with it or not, when time for check out comes, you will no longer be able to use it.
Experts say you also don't need to worry about turning your key card in at the end of your stay; the information expires so the hotels can reuse the cards.
What can corrupt hotel key cards? The most common causes are worn, poor quality, or physically damaged strip. Keep in mind that the quality of the strip isn't the greatest in the first place, as hotels buy cheap keycards in bulk. The quality of the reader and programming machine has an effect also.
Hotel Key Card MythsThe fact is, the majority of hotel key cards store only room numbers and dates of stay. While key cards do come with some risks, detailed financial information is not one of them. Additional information that can be stored on a key card comes down to four key pieces of information: Room number.
No, hotels typically do not charge you for not returning key cards. However, if the card is lost or stolen and needs to be replaced, there may be a fee associated with that. Additionally, some hotels may require a deposit when checking in which will be refunded upon return of the key card.
There are a few things that can actually deactivate a hotel key, including: Being placed near other magnetic cards, such as credit cards or key fobs. Being exposed to magnets, such as those in a purse or backpack. Being bent or damaged.
Typical FeesThe typical fee for a lost key card can range from $5 to $50, depending on the hotel. Some hotels may charge a flat fee for a replacement card, while others may charge per day until the card is returned or the room is checked out.
Additionally, some hotels may require a deposit when checking in which will be refunded upon return of the key card. So while it's unlikely that you'll get charged for simply forgetting to return your key card at check-out time, it's always best to double-check with the hotel before leaving just in case!

Phones do create a magnetic field, but thankfully, it isn't strong enough to demagnetize credit or debit cards. The small magnet in the phone's speaker is the main culprit of generatingthe magnetic field. This field, however, is too weak to cause sufficient damage to a credit card magnetic strip, with some exceptions.
The concern is that the magnetic field generated by a mobile phone could demagnetize the magnetic stripe on the card, rendering it unreadable. However, this is generally a misconception, as the magnetic fields produced by modern mobile phones are too weak to cause demagnetization of hotel key cards.
It is done quite frequently. Many hotels slide your bill under the door during the night, and unless you see any discrepancies on it, you can leave in the morning. The hotel will automatically charge your credit card. This is very convenient and avoids waiting on line at the front desk.
