A situation where it suddenly stops opening trunk by car Nissan Note first generation (E11 body), occurs quite often and causes serious discomfort among owners. This problem can be caused by either a simple battery discharge or a serious failure of the electric drive or mechanical jamming of the lock. Owners Nissan Note E11 Often they are faced with the fact that the button on the lid does not respond, and an attempt to open the door through the interior or with the key does not produce results.
Understanding the design of the trunk access system will help you quickly isolate the problem and possibly avoid a costly service visit. In most cases, the problem lies in worn contacts, a blown fuse, or a broken lock rod. However, sometimes a more in-depth diagnosis of electronic control units is required to return the vehicle to functionality.
Typical causes of opening system failure
The most common reason why trunk Nissan Note E11 refuses to open, is a failure of the electrical actuator (servo drive) of the lock. Over time, the motor inside the mechanism wears out, the brushes wear out, and it stops transmitting force to the latch. There is also a common problem with broken wires in the corrugation connecting the trunk lid to the body, which occurs due to constant vibrations and opening and closing.
Another common culprit is the lock control unit itself, where contacts may oxidize or solder joints may come loose. Owners Nissan Note Sometimes they complain that the button on the door works with a delay or does not work at all, while the central locking responds normally. This indicates a local malfunction in the luggage compartment control circuit.
Mechanical factors should not be ruled out: misalignment of the cover, dirt and ice getting into the lock mechanism in winter, or simply jamming of the drive cable. If you hear the characteristic buzz of the motor when you press the button, but the door does not budge, the problem is most likely in the mechanics or in the latch itself, which has lost its mobility.
Diagnostics via button on the lid and key fob
The first step in diagnosis should be to check the vehicle's response to commands from different control sources. If you have a key fob, try pressing the trunk release button on it. If the door opens, then the problem is localized in the button on the trunk lid itself or in the wiring going to it. If there is no response from any button, you need to look deeper for the problem.
Pay attention to the beeps when pressed. If you hear a quiet clicking sound from the relay, but the motor does not start, there may be a power problem. In some cases lock drive may be blocked due to the activation of the anti-tamper system if a shock sensor or motion sensor inside the cabin has activated the blocking.
It is important to check the condition of the button itself on the lid. It often sticks or the contacts inside it oxidize. To check, you can carefully disassemble the plastic cover around the button and measure the voltage with a multimeter when pressed. Lack of voltage will indicate an open circuit or a faulty button.
Electrical and fuse problems
Electrical diagram Nissan Note E11 protects the trunk release system via a separate fuse. If it's burned out, none of the buttons will work. The location of the fuse box may vary depending on the year of manufacture, but most often it is located in the passenger compartment under the instrument panel or in the engine compartment. It is necessary to find a diagram in the documentation and check the fuse responsible for central locking or trunk.
A common problem is broken wires in the rubber corrugation between the body and the trunk lid. At this point, the wires are constantly bent, and over time the copper core breaks, although the insulation may remain intact. This leads to the fact that the signal from the button on the lid simply does not reach the lock. It is difficult to detect this visually; a continuity check of the circuit is required.
It is also worth checking the ground (negative terminal) on the lock mechanism. Contact oxidation or poor contact with the body can result in the motor not receiving enough current to operate. In winter, moisture that gets into the connectors freezes and blocks the electrical contact.

Mechanical unlocking and emergency access
If the electrics have completely failed, and you urgently need to get things out, you will have to resort to mechanical opening methods. The most reliable way is to get to the lock from inside the cabin. IN Nissan Note E11 The rear seats fold down to provide access to the rear parcel shelf. By removing the shelf and prying up the trim, you can gain access to the lock mechanism.
There is usually a special lever or cable inside the mechanism that mechanically unlocks the latch. You will need to peel back the trim, find this lever and pull it with your hand or a screwdriver. This action simulates the operation of a motor and will allow you to open the trunk lid. Be careful not to damage the plastic trim clips.
If you have access to the trunk (for example, through the folded seats), you can try to manually turn the lock mechanism. Sometimes WD-40 lubricant helps if the problem is jamming due to dirt. Spray lubricant into the lock slot and wait a few minutes, then try opening the trunk with the key.

Step-by-step instructions for replacing the button and lock
If diagnostics show that the problem is in the button on the lid, replacing it will not take much time. Remove the decorative trim around the button, unscrew the mounting screws and disconnect the connector. Install the new button and check operation. This is the simplest and cheapest repair that you can do yourself.
Replacing the entire lock assembly requires more effort. It is necessary to remove the trunk lid trim, unscrew the bolts securing the mechanism and disconnect all connectors. Then remove the old lock and install a new one, after checking the functionality of the new unit. After installation, be sure to adjust the lid gaps so that it closes tightly.
During the work process, it is important to be careful when working with plastic elements. The plastic on older cars becomes brittle and breaks easily. Use special blades to remove the trim so as not to scratch the body or break the fasteners.
How to remove the trunk lid trim?
To remove the trim, you need to find all the mounting bolts (often hidden under decorative plugs). Then carefully pry the plastic clips around the perimeter with a blade. Do not use excessive force as the clips may break. After removing the trim, disconnect the wiring connectors before removing the panel completely.
⚠️ Attention: When removing the trunk lid trim, be extremely careful with the manual opening cable, if it is provided by the design. Its breakage may make it impossible to open the trunk from the inside in the future.
Software glitches and adaptation
Sometimes the problem lies not in the hardware, but in the software of the control unit. Failures in the controller's memory can lead to it "forgetting" commands to open the trunk. In such cases, resetting the settings or flashing the unit can help. However, this is a complex procedure that requires special equipment.
In some cases, a simple procedure of “rebooting” the electrics helps. To do this, you need to disconnect the negative terminal of the battery for 10-15 minutes. After connecting the terminal back, the system is reinitialized and the lock can be removed. It's worth trying before you get into the machinery.
If you have a diagnostic scanner, connect it and check for errors in the system immobilizer or central lock. Errors may indicate a specific node that requires attention. Fixing software errors often solves the problem without replacing parts.
Before disconnecting the battery, make a note of all radio station settings and clock time, as they may reset to zero after a power reset.
Cost of repairs and selection of spare parts
The cost of repair depends on the cause of the problem. Replacing the button on the lid is inexpensive since it is a simple part. Replacing the entire lock assembly will be more expensive, especially if you order original spare parts. Similar parts from other manufacturers or from disassembly may cost much less, but their reliability is lower.
If the wiring needs to be replaced, the cost of the work will increase due to the difficulty of accessing the wires in the corrugation. In this case, it is often easier to install new wires than to restore old ones. The cost of an electrician’s work also depends on the complexity of access to the nodes.
When choosing spare parts, pay attention to the manufacturer. Original parts Nissan usually last longer but come at a high price. High-quality analogues can be a good compromise. Avoid the cheapest Chinese copies as they often break down after a short time.
| Detail | Original (approximate price) | Analog (approximate price) | Service life |
|---|---|---|---|
| Opening button | 3,500 rub. | 1,200 rub. | 5-7 years / 2-4 years |
| Lock assembly | 12,000 rub. | 4,500 rub. | 7-10 years / 3-5 years |
| Actuator (motor) | 6,000 rub. | 2,000 rub. | 8-10 years / 4-6 years |
| Fuse | 100 rub. | 50 rub. | Indefinitely / Indefinitely |
⚠️ Attention: When purchasing a used lock from disassembly, be sure to check its functionality before installation. Opening a closed trunk if the new lock does not work will be extremely difficult and expensive.
Regular lubrication of the lock mechanism and checking the integrity of the wiring in the corrugation can prevent 80% of problems with opening the trunk.
Prevention and operating tips
To prevent the problem from returning, it is necessary to carry out regular preventive maintenance. Inspect the condition of the wire corrugation and, if necessary, change it or install new wires. Timely replacement of worn parts will save you money and nerves in the future.
In winter, be sure to clear the lock of ice and dirt before attempting to open the trunk. Use special lubricants for locks that do not freeze at low temperatures. Regular oil can thicken and block the mechanism.
Don't ignore strange sounds when the lock is operating. If you hear creaking or clicking noises that were not heard before, this is a sign that the mechanism needs attention. Timely diagnosis will help avoid complete breakdown.
