Just a matter of getting conditioned to the new technology. We have a pretty long standing habit of inserting and removing keys from ignitions to stop and start vehicles. At least I never lost the key, by the second day I was used to the keyless start and shutdown. I lost my key to my 09 Sonata about 3-4 years ago in Des Moines Iowa as I parked by a storm drain during a heavy rain and i dropped my FOB and key and they washed away down the drain. Luckily after waiting in a cafe for about an hour for the rain to stop there was a Hyundai dealer about 5 blocks away so I brought my registration and had to buy a new fob and key and it was about $260.00 for key and programming. I have ordered key fobs online for about $40 to $60 but at that time I did not have that luxury so paid what the dealer asked. I suppose these new keyless remotes probably cost much more than $260.00. At any rate I sure would not want to lose one.
