The steps to replace the battery in a 2017 Passat car key are as follows: 1. Press the mechanical key button on the remote key to release the mechanical key; hold the mechanical key end with your right hand, with the Volkswagen logo on the remote key facing upward. 2. Use your hand to pry open the battery cover from the opposite side of the raised edge, exposing the battery. 3. Insert a toothpick into the notch on the edge of the battery and gently pry it out. The battery is a 3V CR2032 alkaline battery. 4. Insert the new battery into the battery slot, close the battery cover, and gently press the cover to ensure it is securely fastened. 5. CR2032 alkaline batteries are available in many brands at supermarkets, with little price difference. It is recommended to purchase a well-known brand.
I'm the kind of person who enjoys fixing things myself, and changing car key batteries is a piece of cake for me. The 2017 Passat's key design is quite common, mostly the foldable remote type, which uses a CR2032 coin cell battery. First, locate a small notch or gap along the edge of the key, usually near the keyring area. Use a coin or a small flathead screwdriver to gently pry open the cover—don't use too much force to avoid breaking the plastic casing. Once opened, you'll see the battery compartment. When removing the old battery, note the orientation of the positive and negative terminals—the standard installation has the positive side facing up. Insert the new battery, ensure it's aligned correctly, then gently snap the cover back into place. Finally, don't forget to test the unlock button to see if the lights flash normally, just to avoid any issues when driving. The whole process takes at most 5 minutes, saving you dozens of dollars at the repair shop while picking up a handy skill. That's the joy of DIY—keeping some tools at home for these tasks is super convenient. However, if the key is too tight or you're unsure about the battery model, checking the manual or looking up reference images online is more reliable.
