Well, so far we've seen Sari's Key... 1. Heal the Autobots. 2. Revive Dead Autobots. 3. Open secured doors. 4. Enhance weapons. 5. Somehow added on Bumblebee's Boosters. 6. Command machines. 7. Disrupt Teacherbots. So given how the toys look and how the key is used in the series, how long untill Hasbro makes some Autobots with Cyberkey gimmicks and have them come with Sari's Key to unlock them? Don't get me wrong, I'm not saying that Hasbro is going to do such a thing, Just that they have in the past and could do so again given this series' story.
