2 Answers
Method for replacing the key battery of Volvo S90: 1. Use a cross screwdriver to unscrew the screws and gently pry open the key shell; 2. There is a square hole on the side of the key. After opening it, replace the old battery with a new one, paying attention to the correct orientation of the battery's positive and negative poles; 3. Install the shell by first inserting one corner, then gently closing it to ensure there are no gaps. The Volvo S90 is a luxury sedan under the Volvo brand, equipped with a new generation 2.0T turbocharged engine across the lineup, featuring a hybrid power system. It utilizes ISG to recover braking energy, effectively reducing fuel consumption and carbon emissions, while also providing smooth and stable starting effects to enhance driving comfort.
I've been driving a Volvo S90 for several years and often change the key fob battery myself. The process is quite simple: first locate the small latch or screw position on the back cover of the key, usually pry it open with a small screwdriver or fine tool, but don't use too much force to avoid cracking. Inside is a CR2032 coin battery - pay attention to the positive/negative orientation of the old battery (usually positive side faces outward). After removing it, directly replace with a new battery, then snap the cover back on and firmly press to test the lock/unlock functions. I recommend using original manufacturer batteries to avoid leakage, and clean the internal contacts with a dry cloth to prevent oxidation. Key fob batteries typically need replacement every two years - watch for flashing light indicators and address promptly. DIY saves money and time, and practice makes perfect. The whole process takes less than ten minutes - safe and efficient. Developing this maintenance habit makes car usage more worry-free.
