Ever Wonder what data is stored in your key?

While the key doesn't charge with comfort access, when you plug in the key, it stores some vital data so your Service Advisor doesn't need to write it down (saves time and improves accuracy)...

So plug it in before you take in for service.....

It is my understanding that you don't have to plug it in to transfer the actual service details. I have had mine never plugged in. On a recent visit to the dealer it had the correct (and accurate) data stored on the key.

I have seen the SA's go back to the car and plug it in to fetch the data. It would be a whole other level of using RFID technology to send and receive data in these keys (other than the rudimentary ID / Key Fob commands).

As long as a turn off the car and the restart it, my key updates. I do this each time I drop off the car.
