[[!meta title="Nico's Porsche Taycan Experience - replacing the key battery"]]
## Introduction
This article is part of the series of
[Nico's Porsche Taycan Experience](/blog/nico-porsche-taycan-experience/).
## The key
Like in any modern car, the key of the Porsche Taycan communicates
wireless with the car for opening and also that it is being present in
the car.
Like any other key, the battery needs to be replaced, when it's empty.
## Replacing the battery
However, unlike other cars, the Porsche Taycan has a weird quirk. When
you replace the battery, go back to the car, the message you get in
the car is "battery low, please replace battery".
The first though one has is, "Wait, what, did I just add the old
battery again?" and "Ohh, did I throw away the new battery?".
So replacing the battery the first time makes you replace it at least
twice, because when you go back to the car again, the messages
persists.
So what happened? Did I buy a pack of (almost) empty batteries?
## Delayed status update
No, the first replacement was already correct. The Porsche Taycan just
needs a few days (!) until it recognises that the battery in the key
has been replaced. This is one of the strangest experiences I had with
a car, but that's how it is with the Porsche Taycan.
The various Porsche Centers confirmed that this is normal.
