2 Answers
The method for replacing the battery in a Subaru BRZ key is: Use a small flat-head screwdriver to pry open the car key. There will be a small gap on the edge of the key, which can be gently twisted to pry open. After prying out the old battery, replace it with a new one. Taking the 2020 Subaru BRZ as an example, it is a sports car with body dimensions of: length 4240mm, width 1775mm, height 1320mm, and a wheelbase of 2570mm. The 2020 Subaru BRZ is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 200PS, a maximum torque of 205Nm, and a maximum power of 147kW, paired with a 6-speed automatic transmission.
As a DIY enthusiast, changing the battery in my BRZ key fob is actually quite simple. There's a small gap on the back plastic cover of the key—just gently pry it open using a small flathead screwdriver or a thin tool, being careful not to apply too much force to avoid scratching the casing. Once opened, you'll see a round coin battery, model CR2032, which can be bought cheaply at any supermarket. When removing the old battery, be cautious not to touch the metal contacts—use your fingernail or a tool to carefully lift it out. When inserting the new battery, make sure the positive side (the side with the text) faces upward and is properly aligned in place. Before closing the cover, wipe the contacts as dust or oxidation might affect connectivity. Press the cover firmly until you hear a click, indicating it's secured. Finally, walk to your car and test the lock/unlock buttons to ensure they work. If they don't, the battery might be inserted backward or there's poor contact—reopen and check. Typically, the battery lasts one to two years, so keep a spare in your car for emergencies. The whole process takes about five minutes, and even beginners can easily learn it on their first try.
