What is the battery model for Nissan Sylphy car key?

[MacBradley]

Nissan Sylphy car key uses a CR2025 battery. The remote key utilizes the wireless remote control function of the central locking system, allowing you to unlock and lock the doors from a distance without inserting the key into the lock. Remote keys can be categorized into three types based on their operation methods: active mode, passive mode, and coil induction mode. The Nissan Sylphy is equipped with a 1.6-liter inline 4-cylinder naturally aspirated engine, paired with either a 5-speed manual transmission or a CVT (continuously variable transmission). It delivers a maximum power of 93KW, maximum horsepower of 126PS, and maximum torque of 168NM, with multi-point fuel injection as the fuel delivery method.

I previously drove a Nissan Sylphy, and the common battery model for the key is CR2025. I replaced it once myself: the key wasn't working well, the remote range became shorter, and upon opening the back cover, I found the battery was drained. I bought a CR2025 from the supermarket, replaced it, and it worked fine again—just remember to install it with the positive side facing up. The key shell is a bit tight, so don't pry it open forcefully; use a small tool to gently open it. The battery typically lasts about one and a half to two years, and it drains faster in winter. Before replacing, check if the buttons are dirty or clogged to avoid unnecessary effort. It's a good idea to keep a spare battery in the car for emergencies, especially before long trips. Opt for reputable brands like Panasonic or Sony for stable quality and leak-proof performance.

Having played with cars for over a decade, I know the Sylphy's key fob mostly uses CR2025 batteries. These batteries operate at 3 volts—don't mistakenly buy CR2032 instead. Replacement is straightforward: pry open the key fob shell, remove the old battery, align the new battery's electrodes correctly when inserting, then snap it shut. Be careful to avoid short circuits or moisture exposure. Battery lifespan depends on usage frequency; with frequent unlocking, you might need replacement in under two years. I've found supermarkets or online purchases offer them cheaply, just a few bucks. If the remote fails, try the spare key first; if both malfunction, it could signal a receiver issue requiring deeper diagnostics.

As a seasoned driver who has been driving a Nissan Sylphy for seven or eight years, I've replaced the key battery with CR2025 a few times. It's quite simple—just buy one from a convenience store, open the key, and replace it. Be careful not to press the key cover too hard to avoid cracking it. If the battery is left unchanged for too long, the remote might respond slower, affecting your efficiency when heading out. DIY replacement is more convenient and cost-effective than visiting a dealership, and it also helps you get more familiar with your car's details. During regular maintenance, check the battery status to avoid last-minute panic when it dies completely.
