What is the battery model for Citroen C5 car key?
2 Answers
Different models of Citroen C5 car keys use different battery models. For example: the second-generation C5 car key uses a CR1620 button battery, while the third-generation C5 car key uses a CR2032 button battery. The method for replacing the car key battery is as follows: Eject the key and place it flat on a table with the logo facing upward. Insert a small screwdriver into the two small holes on the side of the key, then pry the key open upward. When removing the old battery, use a small screwdriver to insert above the battery, press down on the battery, then flip the key over and forcefully pry out the battery. When installing the new battery, first tilt the battery and use the lower part of the battery to press against the elastic small claw inside the key slot, then install the entire battery part.
The battery model for the Citroën C5 car key is typically a CR2032 coin cell. I used to drive an older C5, and when the key battery aged, it would respond slower or stop working—replacing it with this model fixed the issue. Sharing my experience: last winter, my car wouldn’t lock when parked, and after checking, I found it was a battery problem. I bought a CR2032 from the supermarket and replaced it. The steps were simple: use a small screwdriver to pry open the key casing, pop out the old battery, insert the new one ensuring the positive side faces up, and test the function—it worked immediately. I recommend checking regularly and replacing it every two years to avoid trouble on the road. Avoid buying cheap batteries to prevent waste. After replacement, keep the key dry and clean to extend its lifespan by several years.
