Just found this. They make a Cobalt key for approx 20 dollars. I'm guessing this as cheap as it gets. Anyone out there found a cheaper one?
My understanding is that I can order the key online and then bring it to a hardware store (along with my original key) to have it cut. I can then program the new key by inserting into the ignition per instructions in the owner's manual.
My understanding is that the duplicate key can be programmed as follows:
Insert the original key in the ignition and turn the key to the "ON" position. Do not try and start. Just the ON. wait for all dash lights to turn off. It usually takes about 5-10 seconds. Then after the lights turn off, turn off the ign and remove the key. Insert the cut key and do the same. Do not try and start, just turn to the "ON". After the lights are off turn off the ign and remove the key
