I take things for granted until they don’t work.
Take for instance the under-appreciated key fab. I didn’t give it much thought until it didn’t work.
I pushed the unlock button, and there was no answering ca-chunk of the doors unlocking. I pushed the button harder because that seems to work with TV remotes.
Fortunately, the van unlocked, otherwise I would have had to actually insert the key and turn it! I nearly got carpal tunnel just thinking about it. I remember a time in the dark ages when my family actually owned a vehicle that didn’t have a key fab. If we wanted to unlock the van, we had to walk all the way over to the van and use the key. I know, first world problems.
