If the key on your Porsche Panamera (2017–present) — the 971 — has lost its range or shows a low-key-battery message, the coin cell inside is almost certainly flat. It’s a quick swap with a CR2032.
Battery First — What You Need
- A CR2032 coin cell.
If the key is dead you can still start the car: hold the key against the ignition switch as you operate it. The pull-out mechanical key blade unlocks the driver’s door.
Replacing the Cell
- Pull out the mechanical key from the fob.
- Remove the key cover, then the button-cell cover.
- Renew the cell with a CR2032 (correct polarity).
- Refit the button-cell cover, the key cover and the mechanical key.
Lost Key or Adding a Spare
A cell swap keeps the existing coding. A new key must be programmed by a Porsche centre.
If a Fresh Cell Doesn’t Help
- Check the polarity — an upside-down cell won’t work.
- Hold the key to the ignition switch to drive in the meantime.
- Still flagging? A keyless-entry fault can store a code — look it up on autodtcs.com.
