How Long Does the Porsche 911 Key Fob Battery Last?
2 Answers
The battery in a Porsche 911 key fob typically lasts for three years. The method to replace the battery is as follows: 1. Use a flathead screwdriver to pry open the key fob casing. 2. Remove the battery from the circuit board. 3. Install the new battery and close the casing. Taking the 2020 Porsche 911 as an example, its body dimensions are: length 4519mm, width 1852mm, height 1298mm, with a wheelbase of 2450mm, a fuel tank capacity of 64 liters, and a curb weight of 1450kg. The 2020 Porsche 911 features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 3.0L twin-turbocharged engine, delivering a maximum horsepower of 385PS, a maximum power output of 283kW, and a maximum torque of 450Nm, paired with an 8-speed dual-clutch transmission.
As a long-term Porsche 911 driver, I've found that the key fob battery typically lasts about 1.5 to 3 years, depending on usage. If you frequently press the unlock button or operate it from too far away, it drains much faster. For my daily short commutes with just a few button presses per day, I don't need to replace it within two years. However, once during a winter ski trip, the key suddenly failed, forcing me to use the mechanical key inside to open and start the car – quite a hassle. I recommend replacing the battery immediately when you notice the indicator light dimming or the remote becoming less responsive, rather than waiting for it to die completely. Changing it yourself is super easy – just buy a CR2032 battery and do it at home: pry open the key casing, remove the old battery, and insert the new one. Preventive replacement is always better than dealing with problems – a small expense saves a lot of trouble.
