How to Replace the Battery in a New Porsche Key?
2 Answers
The method to replace the battery in a new Porsche key is: 1. Slide the button on the back to the right to remove the mechanical key; 2. Open the back cover and replace it with a new battery. Taking the 2020 Porsche 911 as an example, it is a 2-door, 4-seater hardtop sports car with body dimensions of: length 4519mm, width 1852mm, height 1298mm, and a wheelbase of 2450mm. The 2020 Porsche 911 is equipped with a 3.0T twin-turbocharged engine and an 8-speed dual-clutch transmission, delivering a maximum power of 283 kW and a maximum torque of 450 Nm. Its drive system is rear-engine, rear-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension using multi-link independent suspension.
I often change my car key batteries myself. For the newer Porsche keys, it's not difficult but requires caution. Locate the tiny notch on the edge of the key, then gently pry open the cover using a credit card or plastic tool—avoid metal to prevent scratches. Remove the old battery (usually a CR2032 coin cell) and note the orientation with the positive side facing up when inserting the new one. When closing the cover, press firmly until you hear a click to ensure it's secure. Test the remote lock and unlock functions afterward. My tip: keep a spare key handy just in case. The whole process takes under five minutes, saving you the hassle and cost of visiting the dealership. Regularly check battery levels—replace it early if the indicator light dims when pressing buttons to avoid being stranded. DIY is fun and builds handy repair skills!
