Yup, but if you have access to the interior of the car then you also have access to the ODB2 port and you can teach it that the key transponder you just taped to the pickup ring is legitimate.
Professional outfits will just disable the alarm and lift the car, but the real problem will be when cheap kits start circulating allowing 20-30 recidivist sociopaths to raise mayhem by stealing any scooby they want.
FWIW: the most stolen cars are not the high performance ones. Those attract too much attention. Hardened car theives steal boring econoboxes that noone looks twice at.
