The situation when Nissan Murano stops responding to pressing the remote control button, familiar to many car owners. Most often, the problem lies not in complex electronics, but in a banal battery discharge. In body models Z52 (generation from 2014 to the present) a compact but reliable key fob is used, which requires periodic replacement of the energy source.
The process of replacing the battery in the key Nissan Murano Z52 does not require contacting an official dealership and does not require complex tools. If you see that the indicator on the remote control is blinking dimly or the signals have stopped coming to the car, you need to diagnose and replace it as soon as possible. Ignoring this problem may result in the engine being unable to start if the backup battery also dies.
Signs that the battery needs to be replaced
Determine what battery in the key The Nissan Murano Z52 requires replacement based on several characteristic symptoms. The first and most obvious sign is a significant decrease in the range of the key fob. If earlier you could open the car from a distance of 15-20 meters, now you need to get close to the door handle.
The second alarm is a change in the behavior of the LED indicator on the remote control body. When you press any button, the LED should flash brightly. If the flash becomes weak, rare or completely absent, this is a sure sign of a discharge. In some cases, the vehicle's on-board computer may display a message on the dashboard display indicating that the key's charge level is low.
Sometimes the problem manifests itself chaotically: the button only works the third time or only when pressed hard. This indicates that the voltage has dropped below the critical threshold required for stable operation of the radio module. You should not wait for complete failure, as in a critical situation this will lead to loss of time and nerves.
It is important to distinguish between a low battery and a malfunction of the button itself. If the problem persists after replacing the battery, the contact pads may have oxidized or the microchip may have failed. However, in 90% of cases, replacement power supply resolves the issue instantly.
Choosing the right battery type and tools
For correct operation of the key fob Nissan Murano Z52 It is necessary to use a strictly specified type of battery. The manufacturer recommends a lithium battery form factor CR2032. This is a standard 3 volt flat cell that is widely available and available at any electronics or auto parts store.
Do not try to save money and buy cheap analogues from unknown brands. Cheap batteries often have a low capacity, which will lead to the fact that after a month you will have to disassemble the key again. It is best to give preference to trusted manufacturers, such as Maxell, Duracell, Energizer or Panasonic.
For the replacement process itself, you will need a minimum set of tools. You don't need screwdrivers or soldering irons. A flathead screwdriver with a thin blade or, even better, a special plastic tool for opening electronics housings is enough to avoid scratching the plastic.
- New battery CR2032 (preferably with a margin according to the release date);
- Thin flathead screwdriver or plastic card;
- A clean rag for wiping the body;
- Gloves (optional, to protect from hand grease).
⚠️ Attention: Before purchasing, be sure to check the production date of the battery. Lithium cells lose capacity over time, even without use. Do not use batteries produced more than 2-3 years ago, as they may already be discharged.
- Every year
- Only when it stops working
- I don't remember
- Never changed
Preparing to open the key fob case
Before you begin physical impact on the body, you need to prepare your workplace. Choose a flat surface with good lighting. The loss of small parts, such as a spring or the case itself, in the dark can result in long searches or damage to the mechanism.
Examine the keychain Nissan Murano for visible cracks or defects. In models Z52 The design is quite strong, but if opened incorrectly, the latches can be damaged. Find a special connector or slot designed to separate part of the case. It is usually located at the bottom of the key fob or on the side, near where the metal key plate is attached.
If you have a spare key fob, it's best to use it for training, but in most cases this is not necessary. The main thing is to act carefully and not use excessive force. Nissan plastic is quite soft and easily deformed under excess pressure.
Make sure the key is turned off and not in programming mode. Just take it out of your pocket and place it on the table. If you're concerned about damaging the key's paintwork with a screwdriver, use a plastic card or your fingernail, although a metal tool is faster and more reliable.

Step-by-step instructions for replacing the battery
The opening process itself begins with the separation of the mechanical key. In the keychain Nissan Murano Z52 There is a small locking button. Click on it and pull the metal key out. After this, you will see a recess in the housing where you can insert the tip of a screwdriver.
Insert a thin flathead screwdriver into the slot and gently turn it like a lever. The body will split into two halves. Do not forcefully yank or break parts as this may break the internal latches. Work smoothly, moving around the perimeter if necessary.
Once the case opens, you will see a circuit board with a microchip and a battery. Battery CR2032 held in a special socket. Lightly press the latch or pry the edge of the battery with a screwdriver until it pops out. Make a note or take a photo of which side it was installed on (the plus side usually faces up).
Install a new battery, observing the correct polarity. Press it firmly until the latch clicks. After this, carefully connect the two halves of the case and check how the latches close. Make sure there are no gaps between the pieces and that the metal key button is in place.
- Open the case by pressing the release button and pulling out the key;
- Insert a screwdriver into the groove and carefully separate the halves;
- Remove the old battery and install a new CR2032;
- Connect the case and check the operation of the buttons.
⚠️ Attention: When removing the old battery, be careful not to touch the board contacts with your fingers. Sebum can oxidize the contacts and cause poor contact with the new battery. If you do touch, wipe the contacts with a dry cloth.
What to do if the case does not open?
If the body does not give way, do not use force. Check that you have pulled out the mechanical key completely. Sometimes the latch requires additional pressure. If the groove is not visible, try to find the joint between the front and back covers and carefully move a screwdriver around there until one of the latches opens.
Health check and synchronization
After replacing the battery, it is not necessary to carry out complex synchronization procedures with the car. In most cases Nissan Murano recognizes the new key automatically. Just press any button on the key fob and check if the signal works (the turn signal blinks or a beep sounds).
If the car does not respond, check whether the battery is installed correctly. It often happens that it does not stand up completely or is skewed. Take it out and reinsert it, making sure it fits snugly. Also check if the contacts inside the compartment are jammed.
In rare cases, if replacement does not help, a reprogramming procedure may be required. This is done through the system Immobilizer. This usually involves pressing buttons quickly in a specific sequence or using diagnostic equipment. However for Z52 This procedure is rarely needed.
If the key fob works, but intermittently, the problem may be radio interference or a malfunction of the car's antenna unit. In this case, replacing the battery will not help, and a visit to a specialist will be required to diagnose the transceiver module.
In most cases, after replacing the battery in the Nissan Murano Z52 key, synchronization with the car occurs automatically without additional actions.
Troubleshooting common problems and errors
Sometimes users are faced with the fact that after replacing the battery the key fob still does not work. One of the most common causes is incorrect installation polarity. Lithium cells have clearly marked poles: “+” (plus) and “-” (minus). There are usually markings on the board indicating which side the battery should be on.
Another common problem is contact oxidation. If you have not changed the battery for a long time, the electrolyte waste could damage the metal contact inside the compartment. In this case, it is necessary to carefully clean the contacts with alcohol or an eraser, removing plaque and carbon deposits.
It is also worth paying attention to the integrity of the button itself. If the button mechanism is broken or jammed, the signal will not be sent even if the battery is good. Check the movement of the buttons: they should be pressed softly and return to their original position without jamming.
| Problem | Possible reason | Solution |
|---|---|---|
| Key fob doesn't respond | Wrong polarity | Turn the battery over |
| Short range | Low quality battery | Replace with branded CR2032 |
| The button is not pressed | Mechanical failure | Repair or replacement of the remote control |
| The indicator is not lit | No contact | Clean contacts with alcohol |
| Only one button works | Jammed mechanism | Disassemble and lubricate the mechanism |
⚠️ Attention: Do not use expired batteries. Even if they appear intact, their internal resistance may be too high for the key fob transmitter to operate correctly, resulting in unstable operation of the keyless entry system.
If you have lost the key or it is completely broken, do not try to solder the contacts yourself if you do not have experience. It is better to immediately contact an auto electrician, since damage to the microchip will make the key irreparable without flashing it.
Tips for extending the life of your key fob
To avoid needing the next battery replacement in six months, follow simple operating rules. Do not drop the keychain on hard surfaces. Impacts can damage the solder joints on the microchip or deform the housing, allowing moisture to get inside.
Avoid getting the case wet. Although keychains Nissan have a certain degree of moisture protection, prolonged exposure to water (for example, if you put the key in your trouser pocket and wash them) can lead to oxidation of the board. If the key gets wet, dry it immediately and, if possible, disassemble it for ventilation.
Do not store the key fob near powerful sources of electromagnetic radiation. Although modern chips are fairly secure, constant interference can speed up battery drain and disrupt electronics performance. Also, do not leave the key in areas with extremely high or low temperatures.
Check the condition of the housing regularly. If you notice that the plastic has darkened or become brittle, this is a sign of aging of the material. In this case, you should think about buying a protective case that will protect the case from abrasion and shock, extending the life of your keychain.
Can I use a different type of battery?
It is strictly not recommended to use batteries of a different size or voltage (for example, CR2026 or CR2016). They may be thinner, which will cause poor contact, or have a lower capacity, which will drain them quickly. Use CR2032 only.
