I bought a blank shell for my car key and moved the keypad over. I dug out the little square black chip, moved that over too. I snapped the new key together, tested the keypad (it’s alive!) and took the old metal key (my new one hasn’t been cut yet) along with the new components into my car. I try turning the engine on, and it’ll crank briefly, then give up. Conversely, when I bring my existing, working car key out, it fires up just fine.
Is there a trick to this? I found a video that said “make sure you have the chip in ‘the right way’” (though they neglected to say what is right, so I dug it out and flipped it over for good measure - no difference.
The smart chip can’t possibly know that the key it’s attached to isn’t cut yet, can it? I just don’t want to run out and spend my time getting the new key cut (the $2 cutting fey is negligible) if that isn’t going to solve my problem.
