You got a bad copy. There are no electronics in the door lock. There is a pickup coil that "polls" the key chip when placed in the ignition. The mechanical properties have nothing to do with the chip, and vice-versa.
My 2004 Jeep Wrangler had a security chip in the key. Did just what you're trying to do. Worked great. It would unlock the door & ignition, but wouldn't start the ignition. I always pulled the key at rest stops if I wasn't going to be right next to the Jeep. Just to remove the temptation.
As mentioned, the keys are supposed to be wire brushed on key cutting tool (like a bench grinder with a wire wheel) to knock off the burs & flashing. Should be very smooth. Suggest taking it back, or getting one elsewhere. FWIW, I had mine made at Home Depot. It was so automated it took the skill portion out of the job... which made the average worker capable of making a decent key.
