The situation when Nissan Note The first generation (E11 body) refuses to open the rear lid, which is one of the most common and unpleasant problems for owners of this hatchback. Most often this happens suddenly: you press a button on the key, pull the handle on the door, but the mechanism remains motionless, leaving you without access to the luggage compartment.
The reasons for this behavior can vary from a banal dead battery to the failure of a complex electromechanical lock assembly. In some cases, the problem lies in a break in the traction, and in others, in a failure of the controller software. There is no need to panic, as there are several proven methods for diagnosing and temporarily or permanently solving this problem, allowing you to regain access to the cargo compartment.
The main reasons for failure to open the trunk on a Nissan Note
The first step in solving a problem is to understand the nature of the problem. On the model Nissan Note E11 The opening mechanism is implemented through a combination of electric drive and mechanical traction. If you hear a clicking sound but the door won't budge, the problem is most likely mechanical. If there is silence, then you should look for the reason in the electrical part of the circuit.
A common culprit is wear on the plastic rod bushings or the breakage of the steel cable itself. Over time, the plastic becomes brittle and breaks, losing the connection between the lever on the door and the lock itself. The lock core may also jam due to dirt or moisture, which blocks the rotation of the mechanism when mechanical action is attempted.
Electronic components are also prone to failure. Lock controller may fail due to oxidation of contacts in the connector, which is located in a high humidity area. Sometimes the problem lies in the switch on the door, which stops transmitting the signal to the drive. One should not rule out the discharge of the main battery, since at low voltage the electric drive may not work, although the mechanical part will be in good working order.

Diagnostics of the electrical circuit and control unit
If, when you press a button on the key, you do not hear the characteristic sound of the drive electric motor, you need to check the presence of power. Start by checking the fuse that controls the central locking system and trunk release. In the mounting block Nissan Note it is usually designated as TRUNK or has a corresponding lock icon.
Use a multimeter to check the continuity of the circuit. Check whether voltage comes to the electric drive connector when the button is pressed. If there is voltage, but the motor does not spin, it means that the internal winding of the motor itself is faulty. electric motor drive. In this case, a complete replacement of the unit is required, since repairing the engine in the field is practically impossible.
Another option is a faulty button on the key or in the door. The button on the key fob may have oxidized contacts, and the button on the door handle may break off inside the plastic. Try opening the trunk using the second button on the key, if there is one, or through the keyless entry system (if it is installed and working).

Mechanical emergency opening methods
When the electrical system completely fails, you have to resort to mechanical methods. The most reliable way is to get to the lock from inside the cabin. To do this, you must remove the rear seat trim or rear parcel shelf to gain access to the rear of the lock. On many modifications Nissan Note This can be done by folding down the rear seats and putting your hand through the gap between the backrest and the door.
Inside you will see a plastic lever for the locking mechanism. You need to find plastic rod, which comes from the door handle, and try to manually move the mechanism to the “open” position. Often this lever just needs to be pulled towards you or to the side with force. If you see a cable that is just dangling, it has become unhooked from the lever and can be snagged with pliers.
If access from the interior is not possible due to the body structure, you can try removing the trunk door trim. This is a more labor-intensive process, since it is necessary to dismantle the plastic panel covering the inner cavity of the door. Under it you will find all the mechanics of the lock and will be able to directly influence the locking rod by opening the cover from the inside.
☑️ Tools for emergency access
Repair of traction and replacement of worn elements
After you have managed to open the trunk, you need to eliminate the cause of the breakdown so that the problem does not recur. If you find a break in the rod, do not try to glue plastic or use electrical tape - these are temporary measures that will not withstand the load. The best solution is to replace the entire rod assembly.
To replace, you will need to remove the decorative panel of the trunk door. Unscrew the screws and carefully unfasten the plastic clips. By removing the panel, you will have full access to the mechanism. Disconnect the old rod by pressing the plastic clips and install the new one. Make sure that it clicks into place with a characteristic sound and has no play.
Sometimes the problem is not in the rod itself, but in the guide sleeve. It can be so worn that the cable simply does not transmit force. In this case, it is enough to replace only the bushing or lubricate it and the lock mechanism with a thick lubricant, for example, lithol or a specialized silicone spray. This will reduce friction and extend the life of the mechanism.

How to remove the trunk door trim of Nissan Note E11?
To remove the trim, you need to find two screws at the bottom of the panel (often under the plugs), unscrew them, and then carefully pull the panel towards you, snapping the clips. Be careful not to break the plastic clips as they are very fragile. After removing the panel, disconnect the backlight connector and the opening buttons.
Checking and replacing the lock assembly
If all of the above methods do not help, and the locking mechanism does not respond to either electrical signals or mechanical stress, it is most likely faulty trunk lock assembled. The drive gear could be jammed inside it or the winding of the motor could burn out, which cannot be replaced separately.
When replacing a lock, it is important to pay attention to the condition of the rod that enters the body. It should move freely. Before installing a new lock, it is recommended to lubricate its hinges and internal mechanisms. Also check the condition of the rubber seal to avoid moisture getting into the new unit.
Installing a new lock requires care. It is necessary to correctly align it with the eye on the body so that the door closes tightly and without distortion. After installation, be sure to check the operation of the mechanism both from the button and from the key, making sure that it is securely fixed and easy to open.
⚠️ Attention: When purchasing a new lock, make sure it is compatible with your year of manufacture Nissan Note. In some cases, connectors or mounting locations may vary slightly even within the same E11 body.
Specifics of operation of the electric drive and sensors
Electric trunk drive Nissan Note works in conjunction with a keyless entry system and position sensors. If the system “thinks” that the door is already open (due to a faulty sensor), it will not send a command to the motor. This is a common problem when the lock sensor contacts become oxidized.
To diagnose the sensor, you need to check the resistance at its contacts. When closed, the resistance should be close to zero, and when open, it should be infinite. If the sensor shows incorrect values, the control unit can block the opening command, believing that the door is already slightly open.
Sometimes resetting the body control module (BCM) can help. To do this, you can disconnect the battery for 15-20 minutes. This will clear temporary errors and may restore operation of the drive if the problem was software. If the error returns immediately, it means there is a hardware problem.
| Symptom | Probable Cause | Recommended Action |
|---|---|---|
| Silence when pressing a button | Fuse or motor burnt out | Check fuse, replace motor |
| I hear a click, the door doesn't work | Broken traction or jamming | Replace the rod, lubricate the lock |
| Difficult to open | Door skewed or dirty | Adjust hinges, clean lock |
| Works only from the salon | The door button is faulty | Replace button or wiring |
Prevention and operating tips
To avoid a recurrence of the situation, carry out regular maintenance of the mechanism. Once every six months, clean the seals and insides of the lock from dust and dirt. Use special aerosol cleaners that wash away old grease and remove moisture.
After cleaning, be sure to apply new lubricant. Best to use silicone grease or graphite lubricant. They are not washed off with water and do not attract dirt as much as lithol. Avoid using oil as it leaks quickly and collects dust.
Also monitor the condition of the battery. A deep discharge of the battery can lead to malfunctions of the lock electronics, which sometimes requires reflashing the control unit. If you park outside in winter, periodically lubricate the seals so that they do not freeze to the body, which creates additional stress on the mechanism.
Before the onset of winter frosts, be sure to treat the trunk door seal with silicone grease. This will prevent the door from freezing to the body and eliminate the risk of damage to the lock when attempting to open it roughly.
Regularly lubricating the lock mechanism and checking the integrity of the linkage is the most effective way to prevent the trunk from jamming on your Nissan Note E11.
When to turn to professionals
If independent attempts to open the trunk are unsuccessful, or you are not confident in your abilities, it is better to contact a specialized service. Failure to do so can result in damage to the lock, broken wires, or deformation of the door trim, resulting in more expensive repair costs.
Professionals have access to diagnostic equipment that allows them to accurately determine the cause of the problem. They can quickly find broken wiring, check signals from the key, and perform replacement parts in minutes. In some cases, flashing of the control unit is required, which cannot be done without special software.
It is especially important to contact specialists if you have an alarm system with auto start or a complex keyless entry system. Independent manipulations can disrupt the operation of these systems and lead to the car being locked. Entrust complex electronics to qualified technicians.

⚠️ Attention: If you see that the lock is deformed or there are signs of forced entry, do not try to open it yourself. This can worsen the damage and make it impossible to repair without replacing the entire tailgate.
Should I replace the entire lock or repair it?
Replacing the entire lock is often more cost-effective and safer than trying to repair the old one. Repairs may take a long time, and the reliability of the repaired unit is not guaranteed. A new lock will ensure durability and proper installation.
Why doesn't the trunk open even if the battery is charged?
If the battery is charged, the problem may be oxidation of the contacts in the lock connector, a malfunction of the button on the key, or a break in the wiring inside the door corrugation. It is also possible for the mechanical part of the lock to jam due to dirt or wear.
How to open the trunk of a Nissan Note if the linkage is broken?
You need to remove the rear parcel shelf or rear sofa trim to get to the lock mechanism from the interior. Locate the lock lever and manually move it to the open position by pulling it towards you or to the side.
Is it possible to open the trunk using an app on a smartphone?
The standard Nissan Note E11 model does not support opening the trunk via the mobile app. This requires a specialized alarm system or a keyless entry system with additional modules.
What to do if the trunk opens by itself?
This may indicate a malfunction of the lock sensor or a malfunction of the controller. It is recommended to check the sensor contacts and, if necessary, replace the lock or reprogram the control unit.
How much does it cost to replace the trunk lock on a Nissan Note E11?
The cost depends on the type of spare part (original or analogue) and the complexity of the work. On average, replacing a complete lock with labor will cost from 3,000 to 7,000 rubles, depending on the region and service.
