How to Replace the Battery in a Tiida Car Key?

Steps to replace the battery in a Tiida car key: First, take out the spare mechanical key, then pry along the gap of the remote key shell to open it. Once the shell is opened, you can replace the battery. When opening the key shell to replace the battery, be careful not to damage the key's chip. The Tiida is a compact car under Nissan, equipped with a 1.6-liter naturally aspirated engine. The engine, coded HR16, has a maximum power of 93 kW, a maximum torque of 154 Nm, a maximum power speed of 5600 rpm, and a maximum torque speed of 4000 rpm. This engine features a dual continuous variable valve timing system and uses an aluminum alloy cylinder head and block.
Last time I replaced the battery for my Tiida's key fob, I learned that the key is locating the shell's snap-fit positions. First, use a thin tool like a credit card to gently pry open the gap on the back of the key—don't apply too much force to avoid scratching the casing. Once opened, you'll see a round coin cell battery, typically a CR2025 model. Use a toothpick to gently lift it out, and be sure to note the battery's orientation (positive/negative sides). Insert the new battery in the same orientation until you hear a click, indicating it's properly seated. Finally, press the shell firmly back together and remember to test the unlock button's response. Though the process is straightforward, using the wrong battery model would make all your efforts futile, so I always double-check the battery type beforehand.
As a long-time Tiida owner, I've replaced the key battery three times. First, prepare a CR2025 button cell battery, which you can easily find in supermarkets. There's a thin slit on the side of the key - insert a small flathead screwdriver and gently twist to pop open the back cover. You'll see a metal battery slot inside; use your fingernail to pry out the old battery, being careful not to let the spring plate fly away. Insert the new battery with the metal side facing down and press it gently until it clicks into place. When closing the cover, first secure the bottom before pressing the top, ensuring even gaps around the edges. The most time-consuming part is actually finding the tools - I later attached a mini screwdriver to my keychain, and now the whole process takes just five minutes. After replacement, test the buttons a few times to confirm normal remote control range.
