Lodging Entries that involve electricity during blackouts?

Most all door locks are batteries and no direct current.

I was in a hotel in Lisbon during a power outage a couple of years ago. There were emergency lights in the halls and the keycards still worked. I suspect they have batteries and/or a UPS that kicks in for these systems.

If hotel room doors with a keypad would need electricity, it would mean that the wire to power the keypad would somehow have to be inside the door. That’s very impractical and prone to damage etc. That’s why these keypads are all battery operated, so no problems there.

Batteries I'm sure, with a periodic replacement schedule, if the lock is in the door. You never see a 110 vac (or 240) power cord going into a door. If lock is on the wall... hope it's battery or battery backup.

Last week we got a key from a keypad lockbox on the wall at an old hotel. Got a room key and 2 little chocolates.

Excellent question! I assume anything to do with electrical security would have some kind of power backup.

This incident reminds me of the need to travel with some cash and not to rely on just credit card. In this situation cash is king.

These entry mechanisms are not affected by power outages.

I have one of those keypad entry mechanisms on my front door. It runs off batteries. (Trust me. I had to figure out where the key was when the battery died. ).

I’ve been in a lot of hotels where the batteries have quit working in those card readers. power was still on, but the key card won’t work because somebody has to come change the battery. Not so sure about periodic replacement of the replacement of batteries in most hotel card readers I’ve seen is based on guest complaint.
