Where is the trunk release button on a Nissan Tiida?

The location of the button depends on the year of manufacture and vehicle equipment. In most cases, it is located in one of three places:

• 🔑 On the ignition key (remote opening) - in versions with central locking.
• 🚗 Under the steering wheel on the instrument panel — to the left of the driver, next to the headlight dimmer.
• 🪟 On the inside of the trunk lid — mechanical latch for emergency opening.

On Nissan Tiida J32 (2004–2012) the button is usually built into the key or located on the instrument panel. In restyled versions (2008–2012) it was moved closer to the steering wheel. On Tiida C11 (2012–2019) in top trim levels, the button can be duplicated on the key fob remote control.

If you can't find the button, check:

• 🔍 Instructions for use — it contains a diagram of the location of controls.
• 🔧 Panel under the steering wheel — sometimes the button is hidden under a plastic plug.
• 📱 Multimedia system — in some versions, trunk opening is available through the menu Settings → Comfort.

How to use the trunk button: step-by-step instructions

It would seem that it could be simpler - I pressed the button and the trunk opened. But in practice the owners Tiida are faced with the following nuances:

1. Remote opening (from key fob):

   Press and hold the trunk button on the remote control 2–3 seconds. If the trunk does not open, check the battery charge in the key fob or the synchronization with the car.

2. Button on the instrument panel:

   Press once and a click will be heard and the trunk will open slightly. If the button does not respond, check the fuse F37 (10A) in the block under the hood.

3. Mechanical latch (emergency opening):

   Open the rear door, fold down the trunk trim and pull the cable or lever manually. This will work even if the battery is dead.

Important: if the trunk opens jerkily or with a delay, this may indicate lock drive wear or contact oxidation.

Common trunk button malfunctions and their causes

If the button stops working, there may be several culprits. Here are the most common:

Malfunction	Possible reason	How to fix
The button does not respond to pressing	Oxidation of contacts, broken wire, blown fuse	Clean contacts, check fuse F37, test the circuit with a multimeter
The trunk opens with a delay	Worn lock drive, weak battery	Lubricate the lock mechanism, check the battery voltage
The button works, but the trunk does not open	The lock is jammed, the drive cable is broken	Disassemble the trunk trim and check the mechanism
Remote opening works every other time	Dead battery in the key fob, interference from the alarm	Replace battery, reprogram key fob

Critical fault: If the trunk does not open either with a button or mechanically, do not try to use force - this may break the lock. In this case, it is necessary to disassemble the rear panel of the passenger compartment to gain access to the emergency release cable.

⚠️ Attention! If after replacing the battery the button on the key fob stops working, you need to synchronize the remote control with the car. To do this, insert the key into the ignition switch and turn it to position ON, then press the trunk release button on the key fob 6 times.

How to repair the trunk button yourself

Many problems can be fixed without visiting a service center. Let's look at step-by-step instructions for the most common cases.

1. Cleaning the button contacts

If the button on the instrument panel does not work well or works only once in a while, the contacts are most likely oxidized. You will need:

• 🔧 Screwdriver (for removing the panel)
• 🧴 Alcohol or contact cleaner
• 🧻 Cotton swabs

Step by step instructions:

1. Disconnect the negative terminal of the battery.
2. Remove the plastic trim under the steering wheel (carefully pry it off with a screwdriver).
3. Disconnect the button connector and clean the contacts with alcohol.
4. Reassemble everything in reverse order.

2. Replacing the fuse

If the button does not work at all, first check the fuse. On Nissan Tiida The fuse is responsible for the trunk F37 (10A)located in the block under the hood (driver's side).

How to check:

• 🔍 Take out the fuse and inspect it for burnout.
• 🔋 Replace with a new one (10A only!).
• 🔌 If the fuse burns out again, look for a short circuit in the circuit.

What to do if the fuse is intact but the button does not work?

In this case, the problem may be a relay or a broken wire. Test the circuit with a multimeter from the button to the lock drive. If the resistance tends to infinity, there is a break somewhere. Most often, the wires fray in the corrugation between the body and the trunk lid.

3. Repair of the trunk lock drive

If the button clicks, but the trunk does not open, the problem is in the lock mechanism. For repair:

1. Remove the trunk lid trim.
2. Check the integrity of the cable and plastic drive gears.
3. Lubricate the mechanism WD-40 or silicone grease.
4. If the gears are broken, replace the drive (part number for Tiida J32: 28530-4M000).

⚠️ Attention! When replacing the lock drive, do not use cheap analogues - they often fail after 1-2 months. Original spare parts last 3–4 times longer.

Emergency trunk opening if the button is broken

Situation: the button does not work, the key fob is empty, and there are food or tools in the trunk. What to do?

There are three ways to open the trunk manually:

1. Through the salon:

   Open the back door, fold back the trunk trim and pull the emergency release cable (usually red or orange).

2. Through the lock with a key:

   On some versions Tiida There is a key hole under the license plate. Insert the key and turn counterclockwise.

3. Disassembling the casing (extreme case):

   If the cable is broken, you will have to remove the plastic panel inside the trunk to get to the lock mechanism.

Video instructions (if visualization is needed):

There are many videos on YouTube on emergency trunk opening. Nissan Tiida. For example, search for "Nissan Tiida trunk emergency open". Please note: on restyled models (2010+), the cable may be hidden deeper.

Troubleshooting the trunk button

To ensure that the trunk release button lasts a long time, follow these simple recommendations:

• 🔋 Regularly check the battery charge in the key fob — a weak signal may not work the first time.
• 🧴 Lubricate the lock mechanism 1-2 times a year with silicone grease.
• 🚿 Avoid moisture on the button and contacts (especially in winter).
• 🔧 Check fuses at the first sign of trouble.

It is also worth periodically testing the emergency cable - pull on it to make sure that it is not jammed. If the cable is tight, lubricate it WD-40.

On models with electric lock (Tiida C11) monitor the condition of the wiring in the corrugation between the body and the trunk lid. Over time, the wires fray, which leads to an open circuit.

Frequently asked questions (FAQ)

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