In 1976, the Peugeot Group acquired 89.5% of Citroen's shares and established PSA Holding Company to merge Citroen and Peugeot. In 1991, Citroen formed a joint venture with China's Dongfeng Motor Corporation to establish Dongfeng Peugeot Citroen Automobile Company Ltd., mainly producing passenger cars and light trucks.
I think changing the battery for a Citroën car key is quite simple. I've done it several times myself. I drive a Citroën C4, and the key is the flat remote type, usually using CR2032 or CR2025 batteries, which you can easily buy at supermarkets or online for just a few yuan each. When replacing, first carefully pry open the back cover with a coin or a small screwdriver—don't use too much force to avoid damaging the plastic clips. Note the positive and negative orientation when removing the old battery, and ensure the new battery is inserted with the positive side facing up or aligned as indicated by the label. Press the back cover firmly until you hear a click. Test the lock and unlock functions to ensure they're responsive; if there's no reaction, it might be due to poor contact or incorrect installation. The battery typically lasts about two years, and daily care like avoiding water exposure or excessive heat can extend its lifespan. It saves both money and time—doing it yourself takes less than ten minutes, saving you unnecessary trips to the repair shop.
