Hotel room magnetic key cards can become demagnetized and stop working for a variety of reasons. The most common cause is exposure to magnetic fields from devices such as mobile phones, purse and wallet closures, and other magnetic sources. Additionally, physical damage to the card, such as scratches, bends, or exposure to heat or debris, can also render the key inoperable. Hotels often use low coercivity (LoCo) magnetic stripes, which are designed for short-term use and are more susceptible to demagnetization. Upgrading to high coercivity (HiCo) stripes or RFID technology can help prevent this issue. Furthermore, factors such as poor-quality magnetic stripes, encoder malfunctions, and programming errors by hotel staff can also contribute to key card failures. While demagnetization is a common issue, it can be mitigated through protective measures, technology upgrades, and proper staff training.

What You'll Learn
Exposure to magnets, phones, and other magnetic devices
Hotel room magnetic key cards can stop working due to various reasons, and exposure to magnets, phones, and other magnetic devices is a major cause. The magnetic strip on the back of the card can be affected by magnets, and phones or other magnetic devices can generate a magnetic field that interferes with the data stored on the strip. This is more likely to happen with low coercivity (LoCo) cards, which are designed for short-term use and can be easily erased and changed. Hotels tend to use LoCo cards as they are cheaper, but this makes them more susceptible to accidental erasure.
Mobile phones, in particular, can be a source of magnet exposure that can corrupt the data on a hotel key card. While some sources suggest that the chances of a phone demagnetizing a key card are low unless the card is attached to the phone with a rubber band and left for days, others argue that the powerful speaker magnet in phones can generate a strong enough magnetic field to interfere with the key card's data. Additionally, phones are not the only magnetic devices that can cause this issue. Wallet or purse closures, name tags, signs, and magnetic handbag clasps can also generate magnetic fields that can affect the key card's functionality.
To prevent hotel key cards from being demagnetized by exposure to magnets, phones, or other magnetic devices, guests can take a few precautions. Keeping the key card away from magnetic sources is essential. Guests should also avoid placing the key card on a table near electronic devices like TVs or cameras, as these devices can emit magnetic fields that interfere with the card's data. Additionally, guests can request card sleeves from the hotel to protect the key cards from demagnetization.
Hotels can also take measures to reduce the likelihood of key cards being demagnetized by magnets, phones, or other magnetic devices. Upgrading to stronger magnets, similar to those used in credit cards, or switching to RFID key cards, which are less likely to demagnetize, can be effective solutions. While RFID options may be more expensive and require upgrades to door locks and software, they can enhance guest satisfaction by reducing the frequency of key card issues. Furthermore, hotels can consider changing the encoder at the front desk to a higher coercivity option, such as HICO-2750 OE, which can significantly reduce the problem without requiring changes to the locks. Regular cleaning of magnetic heads on lock heads and encoder heads can also improve read/write performance and reduce the failure rate.

Physical damage, including scratches and folds
Hotel key cards can become demagnetized due to various factors, including physical damage, such as scratches and folds. These cards have a magnetic strip that contains basic information about the guest, and any damage to this strip can render the card unreadable.
Physical damage to the magnetic strip can occur in several ways. For example, if a guest drops their card or keeps it in the same pocket as their keys, the strip may become scratched, making it challenging for the card reader to access the encoded information. Similarly, bending or folding the card can damage the strip, hindering its ability to function properly.
In addition to scratches and folds, other forms of physical damage can also affect the card's functionality. For instance, if a guest accidentally spills a drink on the card or exposes it to excessive moisture, the liquid can seep into the magnetic strip and cause damage. Crumbs or dirt stuck on the card can also interfere with the magnetic strip's ability to be read accurately.
To prevent physical damage to hotel key cards, guests can take some simple precautions. Keeping the card in a protective sleeve or wallet compartment can shield it from scratches and folds. Additionally, avoiding exposure to liquids or moisture can minimize the risk of water damage. By taking these measures, guests can help ensure the longevity and functionality of their hotel key cards during their stay.

Poor-quality magnetic strips
Hotel key cards are often cheaply made, with low-quality magnetic strips. This is because hotels tend to buy key cards in bulk and opt for low-cost options. As a result, the magnetic strips on hotel key cards can be prone to failure.
Magnetic strips can become demagnetized through exposure to magnets, which can be found in everyday items such as name tags, signs, purse and wallet closures, and mobile phones. Keeping these items in close proximity to hotel key cards can potentially damage the magnetic strips and render them unusable.
To prevent issues with poor-quality magnetic strips, hotels can take several measures. Firstly, storing new and used key cards separately at the front desk can aid in troubleshooting and allow for a quick shift to new cards if issues arise. Additionally, regular maintenance and testing of encoders are important, as encoder malfunctions can sometimes be the cause of key card failures.
While poor-quality magnetic strips can be a common issue, proper care and handling of hotel key cards can help mitigate the chances of failure. Keeping the cards away from magnetic sources and protecting them from physical damage, such as scratches or exposure to debris, can help ensure their functionality during a guest's stay.

High temperatures and direct sunlight
It is important to note that not all issues with hotel key cards are due to demagnetization. In some cases, the card may have been encoded incorrectly during check-in, or the lock itself may be old or damaged. Hotel staff should check for these potential issues before assuming the card has been demagnetized.
To prevent hotel key cards from demagnetizing due to high temperatures and direct sunlight, hotels can use key card sleeves to cover the magnetic strip. This protects the strip from exposure to excessive heat and other magnetic devices that could erase the data. Additionally, hotels can upgrade to more durable RFID technology, which is less prone to issues compared to older magnetic stripe cards.
Hotels can also educate their guests on best practices to prevent key card demagnetization. Guests should be advised to keep their key cards away from direct sunlight and high temperatures, such as leaving them in a hot car or on a sunny surface.
