Why the trunk won't open on a Nissan Note and how to fix it: a complete guide

trunk Nissan Note stopped opening and you don’t know what to do? This problem occurs among owners of both the first generations (E11, 2004–2012), and restyled versions (E12, 2012–2020). The reasons may lie in mechanics, electrical, or even simple user error. In 80% of cases, the malfunction is fixed without visiting a service center - you just need to know where to look.

In this article we will analyze all possible scenarios: from a jammed lock to failures in body control module (BCM). You will learn how to open the trunk in emergency mode, which parts most often fail, and when you should really go to the dealer. And for the owners Nissan Note with electric trunk — a separate section with diagnostics of relays and fuses.

1. Primary diagnostics: mechanical vs electrical

Before disassembling the machine, determine the type of problem. If the trunk does not open either from the button on the key or from the interior button, but clicks are heard - the problem is mechanical. If there are no sounds, the electrician is to blame.

Do a quick test:

• 🔑 Try opening the trunk mechanical key (if there is a keyhole). If it works, the electric drive or control unit is faulty.
• 🚗 Press the trunk open button on the dashboard (next to the light switch). Lack of response indicates wiring or fuse problems.
• 🔋 Check if other electrical functions are working (e.g. central locking). If not, the battery is at fault or BCM.

Pay special attention Nissan Note 2013–2016 model years - these models often fail microswitch in trunk lock, which blocks the opening signal. You can replace it yourself in 20 minutes.

2. Mechanical faults: what breaks most often

Mechanical failures usually occur clicks without opening or complete locking of the lock. Here are the top 3 problems:

1. Jammed drive cable. B Nissan Note The cable stretches or breaks over time, especially if the trunk was opened with force. Check its tension - if the cable sags, it will need to be replaced (part number: 72501-4M000 for E11).
2. Wear of plastic gears in the electric drive gearbox. A characteristic sign is the humming of the motor, but the lid does not lift. Gears are sold in a repair kit (for example, 72510-4M001).
3. Seal deformation. The rubber around the trunk becomes dull over time and prevents closure. Run your hand around the perimeter - if you feel resistance, lubricate the seal with silicone grease.

Critical feature: Since 2014, Nissan Note E12 has been equipped with locks with a plastic rocker arm, which breaks at sub-zero temperatures. If the trunk stops opening in winter, with a 95% probability it is to blame.

⚠️ Attention: Don't try to open the trunk Nissan Note using a screwdriver through the gap - this will damage the seal and may break the plastic guides. Use only emergency rope (see section 4).

3. Electrical problems: fuses, relays and BCM

If the trunk does not respond to any button, start by checking the electrical system. B Nissan Note The following are responsible for opening the trunk:

• 🔌 Fuse F37 (10A) in the mounting block (located under the steering wheel on the left). He is also responsible for trunk lighting - if it does not work, the fuse has blown.
• ⚡ Relay R12 (in the same block). If the relay malfunctions, the trunk may open every once in a while or may not respond to a signal from the key fob.
• 📶 Body Control Module (BCM). If other electrical functions (windows, mirrors) also do not work, BCM requires diagnosis.

How to check fuse and relay:

1. Remove the cover of the mounting block (unsnap the 2 latches from the bottom).
2. Remove fuse F37 with tweezers and inspect for broken thread.
3. Swap relay R12 with a similar one (for example, with a fan relay). If the trunk works, the relay is faulty.

For diagnostics BCM you will need a scanner (for example, Launch CReader). Errors B210E or B2178 indicate problems with the trunk control circuit. In this case, only flashing the unit or replacing it will help.

4. Emergency trunk opening: step-by-step instructions

If the trunk is jammed and access is needed urgently, use emergency rope. B Nissan Note it is located behind the rear parcel shelf (on models with a subwoofer, under the trim).

1. Open the rear door and lower the seatbacks

2. Remove the plastic plug on the rear shelf (snap off the 4 clips)

3. Find the orange rope with the loop and pull it down

4. Lift the trunk lid manually-->

On models E12 (2012–2020) the cable can be hidden under the skin. In this case:

1. Remove the plastic trunk sill trim (unscrew 2 screws Torx T20).
2. Pry up the trim on the left side (driver's side) - there is an emergency lever there.
3. Pull the lever towards you until it clicks.

⚠️ Attention: On Nissan Note with the system Intelligent Key After an emergency opening, an alarm may sound. To turn it off, insert the key into the ignition and turn it to ON.

5. Diagnostics and replacement of the trunk lock

If the emergency release works, but the trunk still does not open with the button, the problem is in the lock. On Nissan Note Two types of locks are installed:

• 🔒 Mechanical (on basic versions E11) - breaks less often, but requires regular lubrication.
• ⚡ Electromechanical (on E12 and trim levels with Intelligent Key) - more difficult to repair, but more reliable.

To replace the lock you will need:

1. Disconnect the battery terminal (negative).
2. Remove the trunk trim (unscrew 6 pistons and 2 self-tapping screws Torx T25).
3. Disconnect the lock connector and unscrew the 3 mounting bolts (10 mm).
4. Install a new lock (part number for E12: 72500-4M025) and reassemble everything in reverse order.

After replacement it may be necessary learning key (if you have Intelligent Key). To do this:

1. Вставьте ключ в замок зажигания.
2. Поверните в положение ON 6 раз подряд (с интервалом ≤ 2 сек).
3. Нажмите кнопку открытия багажника на брелке — должен прозвучать сигнал.

6. Prevention: how to avoid problems with the trunk

To the castle Nissan Note lasted longer, follow simple rules:

• 🧴 Lubricate the seal silicone spray every 6 months. This will prevent freezing in winter.
• 🚿 Wash the trunk from the inside once a season - dirt and sand get into the lock mechanism.
• 🔋 Check fuse F37 at every maintenance. Its burnout often signals the beginning of problems with the wiring.
• 🔑 Don't slam the trunk - this deforms the hinges and accelerates wear of the gas stops.

For owners Nissan Note E12 with electric trunk, check required contacts on the lock connector once every 2 years. Oxidation of contacts is the main reason for spontaneous opening or blocking.
