Talk:Keycard lock

For hotel room locks, are combinations routinely changed between guests? If so, how does the lock learn the new combination - wifi?
 * Most of these locks are networked. I am r000t (talk) 13:46, 19 October 2011 (UTC)
 * What might be their power source? I checked carefully for wires.  Through the hinges?  Or maybe they change hundreds of batteries each year? Gil (talk) 00:41, 16 June 2016 (UTC)

Types of Lock
Perhaps they should be categorised into different sensing mechanisms - RFID, Magnetic Strip, Mechanical? Willh26 (talk) 20:39, 13 March 2016 (UTC)


 * ✅ I have added 3 different categories of card lock - RFID is split into 2... passive (no power source required in card) and active (power source in card required). I have never seen an active RFID chip in a card, so have left this category out as a card would have to be pretty big to fit a battery in as well! Willh26 (talk) 08:33, 15 March 2016 (UTC)
