Good question. We created a device (that we call a "Fuel Vault") that we can install in your car's "gas flap." We'll require that you leave your car's gas flap popped open for your first fill-up so that we can install it. After that, we'll be able to get into your gas flap anytime. It doesn't require any permanent modifications to your car, and can be removed anytime.
Locking gas doors are pretty pointless these days, unless you're worried about someone giving you the sugar-in-the-gas-tank treatment. All cars made for the last several years have anti-siphoning measures built into the line to the gas tank.
Interesting, thanks. My understanding was wrong -- I thought the automakers were using actual metal mesh screens to block the passage of siphons. Apparently (according to the GasTapper video I just watched on YouTube) you can just ram the smaller hose right through the obstruction.
And thank you. I wasn't even aware gas tanks had security measures, let alone gadgets to circumvent it until your comment piqued my interest. Pretty interesting.
Crowbar. It's super high tech. Seriously though, I'd like to know too. everything I can think of is either expensive/time consuming (syncing generic new wireless keys, copying physical keys), potentially damaging to the car, or require the provisioning of something that you leave plugged into the obd-2 port. That latter one you could do with 15$ in parts and a cavalier disregard for the cars security, so that could be it?
