Trunk release button on Nissan Tiida: location, setup and repair

Nissan Tiida is a popular compact car that is valued for its reliability and practicality. However, even such a time-tested car may have operational issues. One of the common problems of owners is trunk release button. Where is it? Why does it sometimes not work? Is it possible to reconfigure it? In this article we will look at all the nuances of working with the trunk button on Tiida (including models C11 And C13), and also give practical advice on troubleshooting.

If you are faced with the fact that the trunk does not open with the key fob or interior button, do not rush to go to the service center. In 80% of cases, the problem is solved on its own - just know where to look and what to check. We have collected all the relevant information, including hidden functions, which are not written about in the official manual, and typical mistakes of owners leading to breakdowns.

Where is the trunk release button on a Nissan Tiida?

Depending on the year of manufacture and configuration Nissan Tiida the button can be located in different places. Let's consider all possible options:

• 🔑 On the alarm key fob - standard solution for most configurations. Usually this is a separate button with an open trunk icon or the inscription TRUNK.
• 🚗 Under the steering wheel on the control panel - in some versions (for example, Tiida Latio) the button is built into the light or heating control unit.
• 🪑 On the center console next to the gearshift lever - typical for models 2007–2012. Often combined with the fuel tank opening button.
• 🔧 Locked in the trunk — mechanical button or lever for emergency opening (available in all versions).

The most common option is a button on a key fob. If it is not there, check the equipment of your car: in basic versions Tiida the button may be missing, and the trunk can only be opened with a key. In this case, it is possible to install an additional module (we will discuss this below).

Important! On restyled models Tiida (after 2010) the button on the key fob can be hidden under a cover. To find it, press the top of the key fob - the plastic panel will move, giving access to additional buttons.

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

Using the button seems intuitive, but there are nuances that affect its operation. Let's break down the process step by step:

1. Opening from the key fob:

   Press and hold the trunk icon button (usually 1-2 seconds). Some key fobs require a double press. If the trunk does not open, check:

   • 🔋 Battery charge in the key fob (if discharged, the signal may not reach).
   • 📶 Distance to the car (maximum range of action is 10–15 meters).
   • 🚪 All doors and hood are closed (on some models the lock is activated when the doors are open).

Opening from the salon:

Press the button on the control panel (if there is one). Some trim levels require you to turn on the ignition first. If the button does not respond, check the fuse F27 (10A) in the cabin fuse box.

Emergency opening:

If the electronics fail, use the mechanical button on the trunk lock. It is located under the plastic cover (open it with a screwdriver). As a last resort, you can open the trunk from the passenger compartment by folding the rear seat (if it folds).

Attention: on Nissan Tiida C13 (2012–2016) when you hold down the key fob button for more than 5 seconds, an alarm is triggered. This is not a breakdown, but a function of protection against accidental pressing.

Why the trunk button does not work: main reasons

If the button stops responding, there may be several reasons. Let's look at them in order - from the simplest to the most complex:

Reason	Signs	Solution
Low battery in key fob	The button does not work, but the central locking works intermittently	Replace the battery (type CR2032)
Fuse failure	The button in the cabin does not work, the key fob only opens the doors	Check the fuse F27 (10A) and F30 (15A)
Problems with the lock actuator	I hear a click, but the trunk does not open	Lubricate the mechanism or replace the actuator
Oxidation of contacts	The button works every once in a while, especially in wet weather	Clean the contacts on the button and in the control unit
Malfunction in the body control module (BCM)	None of the buttons work, but the fuses are good.	Diagnostics with a scanner is required (for example, Launch X431)

The most common problem is contact oxidation in a button or control unit. This is especially true for cars older than 5 years. To check, disconnect the button connector and inspect the contacts: if they are green or black, they need to be cleaned.

⚠️ Attention: If, after replacing the battery in the key fob, the trunk button stops working, but the central locking functions, then the key fob requires reprogramming. You can do this yourself (instructions below) or in a service.

How to reconfigure or add a trunk release button

If your Tiida is not equipped with a trunk button, you can install it yourself. Also, sometimes it is necessary to reconfigure an existing button (for example, after replacing the battery or control unit). Let's consider both options.

Installing an additional button

To install you will need:

• 🔧 Illuminated button (for example, from Nissan Note - fits the connector).
• 🔌 Wires with a cross section of 0.5–0.75 mm².
• 🔨 Soldering iron or terminals.
• 📖 Connection diagram (can be found in the repair manual Tiida).

The connection is made to the body control unit (BCM). Basic steps:

1. Remove the center console (unscrew the bolts under the cup holders and around the gearshift lever).
2. Find the connector B220 on BCM (usually grey).
3. Connect the button to the contacts 1 (mass) And 14 (signal).
4. Lay the wires and secure the button in a convenient place (for example, next to the heated glass button).

Important: After installation you may need keychain training, since the control unit recognizes the new button as an additional device.

Reprogramming the key fob

If the trunk button on the key fob stops working after replacing the battery or resetting the settings, follow this procedure:

1. Закройте все двери и багажник.
2. Вставьте ключ в замок зажигания и поверните в положение "ON" (не заводите двигатель).
3. В течение 5 секунд нажмите кнопку открытия багажника на брелке 6 раз подряд.
4. Выключите зажигание и выньте ключ.
5. Проверьте работу кнопки — она должна срабатывать.

If the procedure does not help, then the key fob requires complete reprogramming via a diagnostic scanner. This can be done in the service or yourself using an adapter ELM327 and programs Nissan Consult.

What to do if the key fob is not programmed?

If after 3 attempts the button does not work, check:

- Condition of the immobilizer antenna (located around the ignition switch).

- There are errors in the BCM unit (a scanner is needed).

- Compatibility of the key fob with your Tiida model (restyled versions use different frequencies).

Typical mistakes of owners and how to avoid them

Many problems with the trunk button occur due to improper use. Here are the most common mistakes and how to prevent them:

• 🚫 Using non-original batteries in the key fob. Cheap analogues discharge quickly and can damage contacts. Use only batteries CR2032 from trusted brands (Duracell, Energizer).
• 🚫 Pressing the button when the hood is open. On some versions Tiida this leads to a failure in the control unit. Always close the hood before using the key fob.
• 🚫 Ignoring warning signals. If a double beep sounds when you press a button, this means that the system is locked (for example, due to an open door). Do not try to open the trunk by force - this may break the actuator.
• 🚫 Self-repair of the actuator without diagnostics. If the trunk does not open, first check the fuses and contacts. In 60% of cases the problem is not in the actuator, but in the electrics.

Advice: Once every six months, clean the contacts of the key fob and the buttons in the interior with alcohol. This will prevent oxidation and extend the life of the elements.

What to do if the button is broken: repair or replacement

If the button is physically damaged (for example, a cracked housing or a contact has fallen off), it will need to be repaired or replaced. Let's consider both options.

Button repair

Most often they break:

• 🔘 Microswitch - wears out over time. Can be replaced with a similar one (suitable for buttons) Nissan Almera).
• 🔌 Contacts - oxidize or move away. Just clean it and solder it again.
• 🔦 Backlight - LED burns out. Replace with any suitable size LED (voltage 12V).

For repair:

1. Remove the button from the panel (carefully pry it off with a screwdriver).
2. Disassemble the case (usually it is glued or snapped together).
3. Check the integrity of the tracks on the board and contacts.
4. Replace the broken elements and put the button back together.

Replacing a button

If repair is not possible, buy a new button. Original article for Tiida C11 — 28520-4M000, for C13 — 28520-4M010. Analogs from:

• 🔧 Nissan Note (backlit button, art. 28520-4M020).
• 🔧 Renault Megane 2 (by dimensions and connector).
• 🔧 Dacia Sandero (budget option, but without backlight).

The cost of the original button is from 1,500 to 2,500 rubles. Analogs will cost 2–3 times less. When replacing, be sure to disconnect the battery to avoid short circuit.

⚠️ Attention: When purchasing a button from AliExpress or other sites, check the reviews. Often you come across buttons with incompatible connectors that require re-soldering the contacts.

Hidden functions of the trunk button on Nissan Tiida

Few people know, but the trunk button is on Tiida can perform additional functions if used in a certain way. Here are some useful lifehacks:

• 🔄 Reset central locking settings. If you hold the trunk button on the key fob for 10 seconds, all user settings (for example, automatic closing of windows) will be reset.
• 🔐 Activation of the "jack" mode. Press the trunk button 4 times in a row with the ignition off - the alarm will turn off for 15 minutes (useful when washing or repairing).
• 🚨 Alarm test. When you press the trunk button and the door close button, the buzzer sounds and the headlights flash at the same time (functionality check).
• 🔋 Checking the charge of the key fob. If the LED on the key fob flashes red when you press the trunk button, it's time to change the battery.

These functions are not described in the official instructions, but work on most Tiida (especially on versions with Nissan Intelligent Key). Before use, check on your car - some combinations may differ depending on the year of manufacture.

FAQ: Frequently asked questions about the Nissan Tiida trunk button

Is it possible to open the trunk if the battery is dead?

Yes, there are two ways:

1. Use the mechanical button on the trunk lock (open the plastic trim with a screwdriver).
2. If access to the trunk is blocked, open the rear door from the passenger compartment by folding the rear seat (if it folds).

You can also recharge the battery through the cigarette lighter from the jump charger to use the electric button.

Why does the trunk button only work when the ignition is on?

This is a feature of some configurations Tiida. In basic versions, the button in the cabin is connected via a relay, which is activated only when the ignition is turned on. To fix this, you need:

1. Find relay K30 in the fuse block.
2. Resolder it, giving a constant "+" instead of a control signal.

It is better to entrust this work to an auto electrician, since improper soldering can damage the control unit.

How to turn off the beep when opening the trunk?

The sound signal can be turned off in two ways:

• 🔧 Via the on-board computer menu: go to Settings → Sounds → Trunk alarm and turn off the option.
• 🔧 Programmatically via a diagnostic scanner: in the block BCM disable the option Trunk Alarm.

If your configuration does not have such a menu, the signal is turned off only through the scanner (for example, Launch CReader).

Will the trunk button from Nissan Juke fit on Tiida?

No, the buttons are not compatible. U Juke different connector and case shape. However, you can use the button from Nissan Note (2010–2016) or Renault Megane 2 - they match the fastenings and electrical circuit. Before purchasing, check the connector with your original button.

What should I do if the trunk opens by itself?

Spontaneous opening of the trunk is usually associated with:

• 🔋 By shorting in a button (contacts are most often oxidized).
• 📡 Interference from other key fobs (for example, if there is a car nearby with the same signal frequency).
• 🤖 Failure in the BCM block (reflashing required).

First check the button: disconnect it and see if the trunk will open. If the problem persists, you need to diagnose the control unit.
