Trunk release button on Nissan Qashqai J10: location, diagrams and repairs

Owners Nissan Qashqai J10 (first generation, 2007–2013) are often faced with the problem of finding the trunk opening button - especially if the car was purchased second-hand or the documentation is lost. Unlike later models, where the trunk control is integrated into the key fob or center console, the J10 the system has its own characteristics. This article will help you figure out where the button is, how to use it, and what to do if it stops working.

We will look at all possible ways to open the trunk - from a standard button in the cabin to an emergency mechanism in case of breakdown. You will also learn about typical faults associated with the electric drive and microswitches, and find step-by-step instructions for self-diagnosis. If you are planning to upgrade the system (for example, install an electric drive or a contactless sensor), there are also such recommendations.

Where is the trunk release button in the Nissan Qashqai J10

B Qashqai J10 The trunk release button is located not on the center console, as in many modern crossovers, but in a less obvious place. Main options:

• 🔑 On a key clip (if an original key fob with a trunk button is installed - an option for top-end trim levels).
• 🚗 Under the steering wheel on the left — on the light control panel, next to the fuel tank opening button (in some versions).
• 🪑 On the driver's door — in the block of glass control buttons (rare, but found in restyled models 2010+).
• 🔧 In the trunk — mechanical latch under the casing (emergency option).

The most common option is a button next to the hood release lever (to the left of the steering wheel, under the instrument panel). It can be hidden behind a plastic plug or combined with another switch. If there is no button at all, it's probably yours Qashqai J10 equipped only with mechanical opening (lever under the trunk trim).

To accurately determine the presence of a button, check:

1. Vehicle equipment (in documents or on a nameplate under the hood).
2. The presence of a wire to the trunk lock drive (can be seen by removing the trunk door trim).
3. Reaction to pressing the key fob (if there is a trunk button, pressing the unlock button for a long time may trigger the lock).

Diagram of operation of the electric trunk drive

B Nissan Qashqai J10 with an electric trunk, the system works according to the following principle:

1. The signal from the button (or key fob) is sent to body control module (BCM).
2. The BCM checks the status of the doors (all must be closed) and sends a command to trunk lock actuator.
3. The electric motor of the actuator is activated, the rod moves the latch, and the trunk door is unlocked.

If the trunk does not open, the problem may lie in one of the circuit elements:

Component	Typical fault	How to check
Button in the cabin	Oxidation of contacts, broken wire	Ring the tester when pressed
Keychain	Low battery, damaged transmitting module	Check the operation of other key fob buttons
Fuse F37 (10A)	Burnout due to short circuit	Visual inspection, replacement with a known good one
Lock actuator	Gear wear, motor jamming	Listen to the sound when you press a button (click/buzz)
Wiring	Open or short in the trunk door harness	Testing with a multimeter

In 80% of cases, the malfunction is associated with oxidation of the button contacts or wear of the actuator - these elements are most vulnerable to moisture and mechanical stress.

How to open the trunk if the button does not work

If the electric trunk drive fails, use one of the alternative methods:

Remove the trunk door trim (unscrew the 4 plastic clips)

Find the mechanical cable or latch lever (usually on the right)

Pull the cable down or move the lever to the left

If necessary, lubricate the mechanism with WD-40-->

Detailed instructions for mechanical opening:

1. Open the tailgate (if it works) or fold down the rear seats to gain access to the trunk.
2. Remove the plastic trim from the trunk door. To do this, carefully pry it off with a flat-blade screwdriver, starting from the bottom corner. The clips are fragile - do not use excessive force!
3. Under the casing you will see a metal cable or plastic lever connected to a latch. Pull the cable down or move the lever left (depending on design).
4. If the mechanism is jammed, treat it with lubricant WD-40 or equivalent, then try again.

⚠️ Attention: Do not use brute force to open a jammed trunk - this may break the plastic parts of the latch. If the cable breaks, the entire lock mechanism will need to be replaced.

If the trunk opens but the power transmission still does not work, check:

• 🔋 Fuse F37 (10A) in the fuse box under the steering wheel.
• 🔌 Connector on the actuator (often oxidizes due to moisture).
• 📡 Signal from the key fob (bring it close to the back door and press the button - if it works, the problem is in the antenna).

Diagnostics and repair of the trunk button

If the button in the interior does not respond to pressing, follow these steps:

1. Check power:
   • Remove the button from the panel (by carefully prying it off with a screwdriver).
   • Disconnect the connector and check the voltage at the contacts with the ignition on (there should be 12V).
2. Ring button:
   • In ohmmeter mode, check the contacts for closure when pressed.
   • If the resistance does not change, the button is faulty.
3. Clean contacts:
   • Use alcohol or a special contact cleaner.
   • In case of severe oxidation, clean the contacts with fine sandpaper.

If the button works, but the trunk does not open, the problem may be:

• 🔌 Broken wire between the button and BCM (body control unit).
• 🔧 BCM malfunctions (rare, but requires diagnostics with a scanner).
• 🚪 Jammed actuator (you need to remove the trunk trim to check).

To replace the button, select an analogue according to the catalog number:

• 28521-JM00A — original button for Qashqai J10 (2007–2010).
• 28521-JM00B — for restyled models (2010–2013).

Analogues: Febi (22310), Hella (8ZL 355 309-741).

Modernization of the trunk opening system

If the standard system does not suit you, consider upgrading options:

• 🔄 Electric drive installation (if it was not there from the factory). You will need:
  • Lock actuator (28550-JM00A).
  • Button to interior (28521-JM00A).
  • Wiring and relay (can be taken from the donor).
• 📱 Contactless opening (motion sensor under the bumper). Popular kits:
  • Valeo (for Nissan with CAN bus support).
  • Hella (universal, requires configuration).
• 🔑 Key fob programming (if the trunk button is not activated). To do this you need a diagnostic scanner (for example, Launch X431) and access to BCM.

⚠️ Attention: When installing a proximity sensor, be sure to disconnect the standard trunk limit switch in BCM, otherwise the system will conflict. This will require diagnostic software (for example, Nissan Consult III).

Common repair mistakes and how to avoid them

When independently repairing the trunk button or drive, owners Qashqai J10 The following mistakes are often made:

• 🔧 Damage to trim clips when removing the panel. Use plastic puller, not a screwdriver.
• ⚡ Short circuit when checking the wiring. Always disconnect the battery before working.
• 🔄 Incorrect assembly actuator. After repair, check the stroke of the rod - it should move smoothly, without jamming.
• 📡 Ignoring key fob encoding. After replacing the actuator, the key may need to be retrained.

To avoid problems:

1. Before disassembling, take photographs of the location of the connectors and fasteners.
2. Use dielectric grease for contacts (for example, Liqui Moly Kontaktreiniger).
3. After repair, check the operation of the trunk manually - without connecting the electrics.

What to do if after repair the trunk opens spontaneously?

This is a sign short circuit in control circuit or malfunction BCM. Turn off the fuse F37 and check:

1. Integrity of insulation of wires to the actuator.

2. Condition of contacts in the connector BCM (pins 24 and 25 are responsible for the trunk).

3. Setting up the alarm (perhaps it conflicts with the standard system).

If the problem remains, diagnostics with a scanner is required (errors B210D or B210E indicate a malfunction BCM).

FAQ: Answers to frequently asked questions

Is it possible to open the trunk of a Qashqai J10 without a key if the battery is dead?

Yes, there are two ways:

1. Mechanical cable — remove the trunk door trim and pull the cable manually (described above).
2. back door — if it opens separately, you can fold the seats and get to the trunk from the passenger compartment.

If the battery is completely discharged, recharge it or use the jump charger to open the trunk with a button.

Why does the trunk button only work when the ignition is on?

This is normal behavior for Qashqai J10 — in the trunk button circuit there is a relay that is activated only when the ignition is on (or in the ACC). If the button stops working at all, check:

• fuse F37 (10A).
• Relay K3 in the fuse box (responsible for comfort circuits).
• Settings BCM (the parameters may have gone wrong).

How to turn off the beep when opening the trunk?

The sound signal (beeping) when the trunk is open can be turned off through the on-board computer menu:

1. Click the button TRIP on the dashboard.
2. Go to Settings → Sound signals.
3. Select trunk and set the value OFF.

If there is no such item, the signal is turned off by software through the diagnostic connector (a scanner is required).

Is it possible to install a trunk button on the key fob if it is not there?

Yes, but this will require:

• Buy a key fob with a trunk button (for example, 285E3-JM00B).
• Program it via BCM (need a scanner Nissan Consult or Launch).
• Check compatibility with your version BCM (Dorestayl and Restayl have different firmware).

The cost of reflashing the key fob is about 1,500–2,500 rubles. in the service.

What should I do if the trunk opens but does not close?

The problem is usually related to:

• Jammed actuator — lubricate the mechanism or replace the drive.
• Faulty limit switch — the door position sensor may give a false signal. Check the connector for corrosion.
• Broken cable - in this case, the door does not lock in the closed position.

For a temporary solution, you can close the trunk manually by pressing the latch on top, but this will not eliminate the cause.
