I've seen Youtube videos where they have you do things like putting the key in and out of the ignition and closing and opening the driver's door in a certain sequence to put the car in programming mode (the locks should cycle to indicate you're in programming mode). However, I'm at a loss about getting the lock/unlock/trunk/panic buttons on the keys to work. I managed to program the engine immobilizer with Techstream to accept both keys. My master key is falling apart so I decided to buy two replacement keys from Amazon.
