Right ok Dave, couldnt remember as I drove somebody eles's Corca C a while back (real basic 1000 model) and dont remember having to do the double unlock thingy,
Anti Hijack?, they do come out with strange features sometimes, my Veccy C, late one without the rear Hatch key lock, if it doesnt get used much, and the Battery gives up, normal thing unlock with Key, lift bonnet, lock car with Door Pins, remove Battery to Charge overnight, and the Boot is unlocked during that period without the Battery. I know what the answer is, just a pain having to get another Battery out and Jump Leads to sort it just to lock the Boot, but then youve got the Power Sounder issue over night, so I just tend to leave the Boot unlocked.
