What is the battery model for the Volkswagen Bora car key?
3 Answers
The battery model for the Volkswagen Bora car key is CR2032. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. The breakdown is as follows: C - Indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. R - Indicates the battery shape is cylindrical; if it were square, it would be denoted by F. 20 - Indicates the battery diameter is 20mm. 32 - Represents the battery height of 3.2mm. The nominal voltage is 3.0V, with an endpoint voltage of 2.0V. The rated capacity ranges between 200-240mAh, varying by manufacturer. The shelf life of a CR2032 is typically 5 years, though this can be significantly shorter if the manufacturer's production standards or quality control are poor. Domestic first-tier brands generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can extend to 8 years or even 10 years. Generally, replacing a car key battery involves just three steps: Step 1: Remove the mechanical key. Press the lock button on the side of the smart key to release the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you will see a deep slot and a shallow slot at the top of the smart key. The deep slot is for the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it open to reveal the coin cell battery. Gently push the battery to remove it. Step 3: Replace the battery. Insert the new battery, then reattach the battery cover and mechanical key to complete the replacement.
I've been driving a Volkswagen Bora for several years and have replaced the key battery multiple times. The battery model is the CR2032 button cell, which can be easily purchased at supermarkets or hardware stores at a low cost. The first time I replaced it, I was a bit nervous because the key casing shouldn't be pried open forcefully. Instead, you should gently press it open with a thin tool or your fingers to avoid scratches. When installing the new battery, make sure to align the positive side correctly. There's a small mark on the old battery where the letters CR2032 are located—don't install it backward, or the remote might stop working. The battery typically lasts one to two years, so if the door doesn't respond as sensitively, it's time to check it. By the way, other Volkswagen models also use this battery type, which is very convenient. I recommend checking the battery status during regular car maintenance instead of waiting until it's urgently needed. Test the remote before heading out.
As a car enthusiast, I've handled many models, and the Volkswagen Bora key battery is uniformly CR2032, a standard button cell with strong universality. Replacing it yourself is incredibly simple: press the key button to pop out the spare key, then use a plastic piece to pry open the casing and directly replace the battery. Be careful not to damage the small internal chip, just ensure the battery is placed in the correct orientation. Battery lifespan depends on usage frequency, averaging a replacement every two years. When buying batteries, opt for reputable brands like Nanfu or Energizer, costing just a few bucks. If the key's remote range decreases or the signal weakens, it's time to act. This DIY approach saves money and is quick, so don't rely on repair shops. A little tip: after removing the old battery, double-check the model CR2032 to confirm before proceeding.
