Hotels explain why they use key cards

The Times of India reported on Aug. 6 that hotels have largely replaced metal room keys with electronic key cards because the cards are easier to replace, cheaper to manage across large properties and can be reprogrammed when a guest checks out or a card goes missing. The article said the shift reflects both operating costs and security needs in modern hotels. It cited the added ability to control access to elevators, pools, lounges and restricted floors with the same credential. ### Why is a lost key card less disruptive than a lost metal key? The Times of India said a missing metal key could force a hotel to replace the entire lock to keep a room secure, while an electronic card can usually be canceled and replaced without changing door hardware. That difference cuts both labor and material costs, especially at properties managing hundreds of rooms. (timesofindia.indiatimes.com) Honeywell’s Onity, which sells electronic locking systems to hotels, says electronic locks let operators control access digitally rather than relying on mechanical keys. Onity says it has sold more than 5 million electronic locks and deployed more than 4 million Bluetooth locking systems, underscoring how widely electronic access has spread in hospitality.

ASSA ABLOY says its hospitality systems can turn a guest device into a room key and access pass, while Vingcard, its hotel-lock brand, says modern access management systems are built to control and monitor entry across multiple areas of a property. Those systems let staff issue, change or revoke credentials without replacing locks room by room. (buildings.honeywell.com) Vingcard says its mobile-access system delivers digital keys through encrypted channels to a guest’s phone or watch. That is an extension of the same logic behind plastic key cards: hotels prefer credentials that can be issued quickly, limited to certain doors or dates, and shut off when a stay ends. ### Why do hotels use one card for more than the guest room? The Times of India said the same hotel card can also be programmed for elevators, fitness centers, swimming pools, executive lounges and restricted guest floors. (assaabloy.com) That means hotels can use one credential to manage where a guest can go, instead of handing out separate physical keys or passes. (vingcard.com) An Onity product brochure says an electronic lock can grant access to authorized keycards only at defined times and dates and can record opening activity. The brochure says that setup can reduce liability and improve staff management, because access rights are tied to a digital system rather than a copied metal key. ### Are key cards mainly about convenience or about cost? (timesofindia.indiatimes.com) The Times of India framed the answer as both. The article said key cards make check-in and replacement easier for guests, but also help hotels avoid the expense and time involved in replacing locks after key losses. A 2026 hotel key-card system pricing guide published by security retailer Safe and Sound said electronic lock systems still require significant upfront spending on hardware, software and installation, with costs rising by property size and technology level. (hoteltechnology.cz) Even so, the guide described replacement, software and maintenance as predictable operating expenses within a centralized system, rather than the ad hoc cost of changing physical locks after security incidents. (timesofindia.indiatimes.com) ### Where is hotel access technology heading next? ASSA ABLOY and Onity now market mobile access alongside physical cards, showing that hotels are moving from swipe cards to phone-based credentials rather than back to metal keys. Vingcard says its mobile system works through Bluetooth Low Energy, and ASSA ABLOY says guest devices can function as both room keys and access passes. Honeywell’s Onity and ASSA ABLOY’s Vingcard continue to present electronic credentials as the standard hotel access model on their current hospitality product pages, with physical cards still in use but increasingly paired with mobile entry options.
