Waste of Money?
I don't think so - there are other advantages: allows you to intentionally leave your keys in the vehicle [out of sight], if you don't want them in your pocket, for jogging or something. Also allows others - wife, etc., access to the vehicle while separated, antique shows, etc., a true convenience item if you want to get in your car @ home, & your keys are in the house. There probably aren't many of us who haven't ever accidentally locked ourselves out of a car. :cursin: It is a nice feeling to know you have a car which you cannot lock yourself out of!
And Tweak, I have seen them in the aftermarket. Some of them look pretty good, the only prob I would have is where to put it.
I think the only acceptable place [for me] would be, like some Exploder's, on the B-pillar, vertically, but I'm not sure that's doable on 4Rnr. Not sure I could take the Dremmel to my truck anyway! Let us know if you pursue.
