Steps to replace the battery in a Tiida remote key: 1. Open the smart key shell from the side seam; 2. Remove the old battery and insert the new one, then close the cover. Taking the 2021 Tiida as an example, its body dimensions are: length 4393mm, width 1766mm, height 1539mm, wheelbase 2700mm, and fuel tank capacity 50L. The 2021 Tiida is equipped with a 1.6L naturally aspirated engine, with a maximum power of 90kW and maximum torque of 155Nm, paired with a 5-speed manual transmission. It adopts a front suspension type of MacPherson independent suspension and a rear suspension type of torsion beam non-independent suspension.
That time my Tiida's remote key fob stopped working—pressing the buttons had no response—so I guessed it was a battery issue. Find a small screwdriver or similar tool, insert it into the gap of the key fob shell, and gently pry it open. Don't use too much force to avoid damaging the plastic parts. After opening it, you'll see a small coin cell battery, usually a CR2025 model. Take it out and check that the positive side is facing up. Go to a supermarket or electronics store to buy a new battery, making sure to get the matching model and a reliable brand like Panasonic or GP Duracell for better durability. When installing the new battery, ensure the electrode direction is correct with the convex side facing up, then press it firmly in place and close the shell. Test the unlock and lock functions—if they work smoothly, you've succeeded. The whole process takes about ten minutes and saves money. It's best not to wait until the key fob completely fails; check it when the buttons start responding sluggishly. Don't throw old batteries away carelessly—dispose of them in a recycling bin for environmental reasons. Batteries should be replaced every two years to keep the key fob functioning smoothly. If you're unfamiliar with the process, searching for a video tutorial online can make it easier—just be careful not to damage the shell when prying it open.
