I too thought the $1000 for the keyless was useless as I did the dynamic steering, but both have turned out to be among the best of the upgrades I've done (and I've done more or less all of them but one!).. The best part of the keyless is your wife will not have to fumble for her keys when she's out and about and that is a security issue when you think about it.
