To replace the battery in a Tiida car key: Use a tool to open the key casing from the side seam, remove the old battery, and replace it with a new one. Taking the 2021 Tiida as an example, it is a compact car with body dimensions of 4393mm in length, 1766mm in width, and 1539mm in height, with a wheelbase of 2700mm and a curb weight of 1180kg. The 2021 Tiida is equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 122PS, a maximum torque of 155Nm, and a maximum power of 96kW, paired with a 5-speed manual transmission.
I drove a Tiida for several years, and replacing the key battery was a routine task. First, locate the key casing, which usually has small clips on the side. Use a coin or a small screwdriver to gently pry it open. Remove the old battery and check its model—the Tiida typically uses a CR2032, which you can buy for a few dollars at the supermarket. When installing the new battery, make sure the positive side faces upward to avoid reversing the polarity and rendering the key non-functional. The whole process takes less than two minutes, but handle it gently to avoid damaging the plastic casing. After replacement, test the remote function: walk up to the car and press the unlock button to see if it responds normally. If issues persist, the contacts might be dirty—clean them with a cotton swab and try again. It's advisable to check the battery every one or two years. Pay attention to weakened key signals as a sign to replace the battery—this saves money and ensures safety.
