I keep my key in a faraday pouch, so keyless entry is actually less convenient than just having a key...I do think that keyless entry and keyless start is a solution to something that was not a problem anyway.
You need to be in the car to drive it, and if you have the physical capability to drive then you're very likely to have the manual dexterity to insert a key and turn it.
I suppose not having to retrieve a key from your pocket/bag, press a button, then put it in the ignition and turn it will be a tiny bit more convenient, but is this extra layer of technology that is so open to exploitation worth it? I don't think so.
