What’s wrong with this headline?

I see only five problems in it and a sixth in the subhead:
1) It’s illiterate. “… your teen …” refers to one person while “… them …” is plural. You can write around this sort of thing quite easily. Since the photo shows a girl you could change “them” to “her” and nobody would mind except old school purists who know that the neutral objective form of the third person singular in English is “him.” (The French have no problem with this. Is it possible that we’ve become more politically nitpicky than the French?) You could change “teen” to “teens”. You could recast the sentence with no pronouns. But I’d be tempted to change the concept of the ad to show a Mom with a son or daughter (or both) and use their names.
2) The headline is in the form of a command. It’s a bad idea to order people around.
3) It’s vague: keys to what? which card? Didn’t Amex long ago establish that “the card” is the American Express card?
4) No clear benefit to the reader.
5) The headline is unnecessary. The subhead does a much better job all by its lonesome.
6) The asterisk at the end of the subhead is annoying. People get suspicious when they see asterisks.
Otherwise it’s a great.
