Different way of immobilising car...?

[hogweed]

Here’s a different one. When I park my car at Bristol Airport, nice and close to the car park check in office, they move it to a different county by the time I get back – so I have to drag my suitcase in the rain about ¼ of a mile over the rocks, boulders, puddles and pools of mud they call a car park, to where they’ve parked it.

No, the “Silver Zone” car park doesn’t like to waste money on a courtesy bus, surfacing or anything else which might benefit the customer – that’s how monopolies work.

Anyway, my old M3 had the facility to enter a code which disabled the car, which was VERY handy. Of course, they whinged at me every time I came back, but at the end of the day, my car was still where I’d left it, only 100 yards from the check in.

So… what would be the easiest way of “secretly” immobilising the motor when I leave it there? I’m thinking a hidden switch under the dash or something maybe, but I wouldn’t know which connection to break – I’m nervous about “partially” cutting power or something by accident, and ending up in some sort of scenario like I’ve seen mentioned here before when people repeatedly try to start the car with a flat battery etc. and it knocks the key code out or something evil.

I’m not much of a lateral thinker – so there may be something really obvious I haven’t thought of!

Cheers all
