Very rarely, I sing the praises of some “new” invention.
Related to this, the greatest recent invention (already being supplanted) is the keyless REMOTE. Remote lock/unlock, etc, is fantastic. I got my 1st c.15 years ago, and since then they’ve started incorporating it right into the “key” itself - which is NOT so great. Highly expensive mechanical keys that you can’t just go and get copied. But the SEPARATE remote is great - I can still get an easy copy of my real key, and use my remote access features regardless.
When mine broke on my old 2010 Mazda 6 it was a $1000 dollar job at the dealer (local mechs wouldn’t touch it) or figure it out myself.
I found figuring out myself was like troubleshooting the space shuttle..
this thing would sense me approaching or leaving the car and lock/un-lock automatically.
it all broke....lucky for me it still sensed the fob for the push button start to work.
