Locking gas cap or locking gas lid??

Was thinking about that the other day. I don't know why they went away from locking door. I know it's lazy but I don't like taking keys out to unlike. I forget almost every time to grab em lol

 

I just bought a Gates and tried it on and seems to work nicely. Just trying to figure out how to get the old one off without breaking its little attachment in case I want to put it on later. Any tips on that? My biggest concern is vandalism. The more modded out your truck gets, the more of a target it is. My 2006 taco was stock except for aftermarket wheels and tires and a Coachella sticker on the back window. I don't have any enemies. Someone slashed my tires while I was rock climbing. It was singled out from a whole parking lot full of vehicles. People are dicks.
