What kind of battery is needed for the Nissan Murano Z52 key?

In the keys Nissan Murano Z52 uses a standard type battery CR2032 with a voltage of 3 V. This is a lithium “tablet” with a diameter of 20 mm and a thickness of 3.2 mm. It is important to choose a high-quality analogue, since cheap batteries often have a lower capacity and discharge faster.

Characteristics	Meaning
Battery type	CR2032 (3V)
Recommended Brands	Duracell, Energizer, Panasonic, Maxell
Service life	2–4 years (depending on frequency of use)
Cost	from 50 to 200 rubles (depending on the manufacturer)

Some owners try to save money by buying batteries from unknown brands or using rechargeable batteries like ML2032. However, this is fraught with problems:

• ⚡ Rechargeable batteries have a lower voltage (2.4 V instead of 3 V), which can lead to unstable operation of the key.
• 🕒 Cheap batteries discharge 2-3 times faster, especially in cold weather.
• 🔧 Low quality components may leak and damage the key board.

If you live in a cold climate, choose batteries marked "Arctic" or "Extreme" - They tolerate low temperatures better.

Preparing for Replacement: Tools and Precautions

To replace the battery in the key Murano Z52 you will need:

• 🔧 A flat screwdriver with a thin tip (or a plastic pick for disassembling cases).
• 🔋 New battery CR2032.
• 🧲 Small magnet (optional, for removing the metal cover).
• 📸 Smartphone for photographing the process (in case you have to assemble the key in reverse order).

Before you begin disassembly, consider a few important points:
