Nissan X-Trail T31 (2007–2013) is one of the most popular crossovers on the secondary market, but owners often encounter problems with the trunk locking. Either the battery is dead, or the drive is broken, or the key is lost - there are a lot of reasons. In this article we will look at all possible ways to open the trunk, including emergency ones, and we will also tell you how to diagnose and eliminate typical faults.

It is important to understand that the design of the rear door T31 different from newer generations (T32 And T33). There is no electronic button on the door (as in T32), but there is a mechanical lock and an emergency opening cable. If this is your first time encountering such a problem, do not panic: in 90% of cases, the trunk can be opened without the help of a car service.

1. Standard methods of opening the trunk

Let's start with the basic methods that should work if the system is working properly. These methods are suitable for everyday use and do not require disassembling the car.

Method 1: Button on the key (central locking)

• 🔑 Click the button opening the trunk on the key fob (usually indicated by a trunk pictogram or inscription TRUNK). On X-Trail T31 This is a separate button, not a combination with a hold.
• 🔋 If there is no reaction, check the battery charge in the key. On keychains Nissan element used CR2032.
• 🚗 Make sure that the car does not have an alarm (some security systems block the trunk from opening).

Method 2: Button in the cabin

• 📍 Look for the button on the panel near the driver's seat (usually to the left of the steering wheel, under the air deflector). On T31 it can be combined with the central locking button.
• 🔄 If the button does not respond, check the fuse F30 (10A) in the cabin unit - it is responsible for the electric drive of the trunk lock.

Method 3: Mechanical key

• 🔓 Insert the metal key from the kit into the lock on the trunk door (under the handle). Turning clockwise will open the lock.
• ⚠️ Attention: If the key does not turn, do not apply force - this may break the cylinder. Lubricate the lock WD-40 or graphite lubricant.

2. Emergency opening of the trunk from the passenger compartment

If the electronics fail (the battery is dead, the fuse is blown, the drive fails), you can open the trunk from inside the cabin through the folding rear seats. This method works for everyone X-Trail T31, regardless of configuration.

Step by step instructions:

1. Fold the rear row of seats (pull the hinges on the backrests or press the buttons in the trunk, if available).
2. Get into the luggage compartment and move aside the trim near the lock (it is attached to plastic clips).
3. Find emergency opening rope - it is usually bright orange or red, attached to a lock.
4. Pull the rope down or to the side (direction indicated on the label). The lock should click.

If the cable is not visible or is broken, you will have to remove the trunk door trim. To do this:

• 🔧 Unscrew the two screws at the bottom of the casing (under the rubber seal).
• 🕳️ Carefully pry the clips with a plastic spatula, starting from the corners.
• 🔍 Under the casing you will see the lock mechanism. Try manually moving the latch with a screwdriver.

3. Opening the trunk when the battery is dead

One of the most common problems is dead battery. In this case, the electronics do not work, but mechanical methods remain available. Here's what to do:

Option 1: Recharge the battery

• 🔌 Connect the charger or “light” from another car. 5-10 minutes are enough for the central locking to work.
• ⚡ If the battery is completely dead, try opening the driver's door with the key and starting the engine.

Option 2: Use a hidden button

On X-Trail T31 there is one under the trunk handle hidden mechanical button. To activate it:

1. Press the trunk handle (as if you were opening it normally).
2. At this moment, press small ledge under the handle (it is located closer to the license plate).
3. If the lock is working properly, it will open.

4. Diagnosis of trunk lock faults

If the trunk does not open in any of the ways, the problem may lie in mechanics or electrical. Let's look at typical breakdowns and their symptoms:

Symptom	Possible reason	Solution
The button on the key does not work, but the central locking works	The trunk lock drive is faulty	Check the fuse F30, use a tester to measure the voltage on the drive (should be 12V when the button is pressed)
Mechanical key does not turn	The lock is frozen or dirty	Treat the larva WD-40 or disassemble the lock for cleaning
The trunk opens but does not close	Broken latch or worn hinges	Adjust the hinges or replace the latch (part number 80520-4M000)
The click is heard, but the door does not open	The emergency opening cable has become frayed or has come off the fastening.	Disassemble the casing and check the integrity of the cable

Critical malfunction: if the alarm goes off when the trunk is opened, but the door does not lock in the open position, the limit switch microswitch is broken. Replacing it will cost 1,500–2,500 ₽ (article 36410-4M000).

How to check the trunk lock actuator with a multimeter

1. Remove the trunk door trim.
2. Locate the drive connector (usually black, with two wires).
3. Connect the multimeter in dial mode: when you press the open button, a sound signal should be heard.
4. If there is no signal, the problem is in the wiring or the central locking control unit.

5. Disassembling the trunk lock: step-by-step guide

If you've tried all the methods and the trunk still won't open, you'll have to disassemble the lock. This is an extreme measure, but it will help avoid costly repairs in the service.

Required tools:

• 🔧 Phillips screwdriver (PH2).
• 🔨 Plastic spatulas for removing trim.
• 🔗 Set of socket wrenches (for dismantling hinges).
• 🧴 Lubrication LIQUI MOLY LM47 or similar.

Instructions:

1. Remove the tailgate trim (as described in section 2).
2. Disconnect the lock drive connector (if equipped).
3. Unscrew the three bolts securing the lock (two on top, one on bottom).
4. Remove the lock and inspect it for damage. Most often the plastic rod or spring breaks.
5. Lubricate all moving parts and reassemble in reverse order.

⚠️ Attention: When disassembling the lock, do not lose it small spring inside the mechanism - without it, the lock will not lock in the closed position. If the spring is broken, replace it with a similar one (for example, from a lighter).

6. Prevention of problems with the trunk lock

To avoid problems in the future, follow these simple guidelines:

• 🔑 Lubricate the lock regularly (1-2 times a year). Use graphite lubricant or WD-40 Specialist (not regular WD-40!).
• 🔋 Check the battery charge before long-term parking. On X-Trail T31 critical voltage - below 11.8V.
• 🚿 After washing the car dry the castle compressed air to avoid corrosion.
• 🔧 Check once a year emergency opening cable tension. If it is sagging, tighten it.

If your Nissan X-Trail T31 often stands outside in winter, install lock heating (for example, from Webasto or Hella). This will prevent the mechanism from freezing at temperatures below -20°C.
