Keyless Access and Kessy need more power.

However, neither the key nor the display shows the car that the battery is discharged slightly. After about two years of use of the new car, I should take the key but in your hand and press the button to open because Kessy no longer worked. VW workshop could not find the problem, because the battery was still 3.07 V. But that is enough for Kessy does not determine or Kessy chip shuts down to save power. In the description there is nothing to it. Energizer button cell had over 3.2 V and Kessy went back. NoName would be absolutely wrong. Only brand button cell as Energizer should be used here.
