Porsche Key Fob Battery Dead, Spare Key or Keys Locked in the Car?

Porsche cars in Singapore

Porsche owners in Singapore, from the 911 to the Cayenne and Macan, expect careful, damage-free work, and that's how we work. We work on Porsche models including the 911, Cayenne, Macan, Panamera and Taycan.

A typical Porsche call

This is the kind of Porsche call we often get: A Macan owner wants a spare key but doesn't want to leave the car at the dealer. They send us the model year and a photo of the key, and we tell them honestly before booking whether it's a remote key we can clone or a smart key that needs the dealer.

What's different about Porsche keys

Porsche Entry & Drive works from your pocket on many models. The car-shaped fob still holds an emergency key for the driver's door. Porsche keys are car-shaped remote fobs, and many models offer keyless entry and start. Most fobs contain an emergency key for the door.

Porsche key fob battery dead? How to get in and start

1. Get in: Press the release on the car-shaped fob to free the emergency key, then use the driver's door lock.
2. Start the car: On models with an ignition on the left of the steering wheel, insert the fob or the ignition handle as normal. On keyless models, your manual shows the backup spot to hold the fob before pressing start.

Details vary by year, so check your manual. Still stuck? Call us. Key locked inside instead? See keys locked in the car.

Porsche key battery: CR2032

The car-shaped Porsche key used on the Macan, Cayenne, Panamera and 911 takes a single CR2032. Turn the key over, release the emergency key and pull it partway out, then press it away from the key body to lift off the back cover. Fit the new cell + side up; if the cover won't close, the cell is the wrong way round. If your key doesn't open this way, don't force it: check the handbook.

Locked out of a Porsche

Tight panel gaps and expensive paint are exactly why the wedge-and-rod tricks from online videos are a bad idea on a Porsche. We use non-destructive entry tools made for modern cars, and we check the log card and your NRIC before we start.
