What is the battery model for Volkswagen car keys?
2 Answers
The battery models for Volkswagen car keys are CR2016 and CR2025. Below are situations indicating that your car key battery needs replacement: Shortened remote control range: If the key only responds when very close to the car door, this is likely due to a drop in battery voltage, which weakens the remote control's signal transmission capability, resulting in a shorter operating range. Occasional malfunction: If you need to press the button multiple times to unlock the door or get a response, this often indicates that the remote battery is nearly depleted. Dim indicator light: Observe the indicator light on the key. If it appears dimmer than usual or flickers when you press the button, this also suggests the battery is running low.
The battery in my Volkswagen car key was recently replaced, and the model is usually CR2032, which is that small, round coin-shaped button battery. Once, the car key stopped working—pressing the buttons had no response—so I opened the key casing myself to check and found the battery was nearly dead. CR2032 batteries can be bought at supermarkets or online for just a few bucks each, and replacing them yourself is easy. However, be aware that different car models might have slight variations—for example, both the Passat and older Golf models use this type, but the latest models might differ. I’ve also heard that the battery life is about 1-2 years, so it’s good to check occasionally to avoid being stuck when you’re out. Be gentle when replacing it to avoid damaging the contacts—last time, I almost cracked the plastic casing while handling it.
