IMO, your concerns about keyless starting are misplaced. Electronic systems are more reliable than mechanical systems. If you put a lot of keys on your key chain, the weight can lead to damage to the ignition cylinder. This won’t happen with a push button start system.
I have the push button start in my 2017 Honda Accord EX-L. The proximity feature for the keyfob also makes getting into the car or the trunk nearly effortless. All doors unlock when I put my fingers inside the driver’s door handle. I don’t have to fiddle with the key. This also works for my wife if she gets to the door handle first; she can open the passenger door if I’m next to the car. There is also a push button for the trunk. With my keyfob in my pocket, I can push that button and the trunk pops open.
One Of These Days Real Soon Now, my wife will start looking at a new car, and I will insist on this feature. It’s one of the biggest improvements between my 2005 Accord and the 2017.
