<em>Nissan Tiida</em> hatchback trunk button: where is it located, how to repair and replace

Trunk release button on Nissan Tiida A hatchback may seem like a small thing, but its malfunction can cause a lot of inconvenience. Especially if the trunk refused to open at the most inopportune moment: in the rain, with your hands full of shopping, or when you urgently need to get tools. In this article we will look at where exactly the button is located on different modifications Tiida, how to diagnose a breakdown and what to do if it stops working - from simply cleaning the contacts to completely replacing the mechanism.

Owners Nissan Tiida Models from 2007–2013 (restyled and pre-restyling versions) often encounter typical problems: the button gets stuck, does not work the first time, or does not respond at all to pressing. The reasons may lie in the wear of plastic parts and in electronics - oxidation of contacts or broken wiring. We have collected proven solutions that will help you save on service costs and restore functionality yourself.

Where is the trunk button located? Nissan Tiida hatchback

Depending on the year of manufacture and configuration Tiida, the trunk opening button can be located in three places:

• 🔑 On the ignition key — in most configurations (except for basic ones), the button is integrated into the remote control. It is usually indicated by an open trunk icon and is located next to the central locking button.
• 🚗 On the dashboard — to the left of the steering column, under the headlight adjustment lever. In some versions, the button is combined with the hood opening lever (pressed down or to the side).
• 🪟 On the trunk door — a hidden button under a plastic cover (requires pressing with a key or a special lever in case of battery discharge).

On Nissan Tiida 2011–2013 (restyling) the button on the instrument panel is often made in the form of a small slider with a trunk icon. In pre-restyling models (2007–2010), it can be round or square, with or without backlight. If the button is missing on the panel, check the package contents: in basic versions Tiida Visia it might not have existed in the first place.

To determine the exact location, use diagram at the end of the article or check the instruction manual for your modification. If the button does not work in any of the listed places, the problem may lie in central locking control unit or fuse.

Typical trunk button malfunctions and their causes

According to statistics from service centers, 70% of trunk button failures are Nissan Tiida due to mechanical wear or electrical problems. Here are the most common symptoms and their possible causes:

Symptom	Probable Cause	Remedy
The button does not respond to pressing	Contact oxidation, wire breakage, microswitch malfunction	Cleaning contacts, checking wiring, replacing microswitch
The button gets stuck or works only once	Worn plastic guides, dirt ingress	Disassembling and cleaning the mechanism, lubrication
The trunk opens spontaneously	Short circuit in wiring, control unit malfunction	Electrical diagnostics, replacement of unit or wiring
Button backlight does not work	Burnt out LED, open backlight circuit	Replacing the LED or restoring the contact

Buttons on Tiida with a mileage of more than 150,000 km - plastic parts dry out and contacts oxidize due to moisture (for example, after washing or rain). If the button stops working after battery replacement or disconnecting terminals, the problem may be in resetting the control unit. In this case it will help key retraining (procedure described below).

⚠️ Attention: If the trunk does not open either with the button or with the key, do not try to force it open. B Nissan Tiida hatchback trunk lock is connected to the central locking, and rough intervention can damage the mechanism or set off the alarm. Use emergency opening method.

How to fix the trunk button with your own hands: step-by-step instructions

If the button on the instrument panel stops working, but the trunk can be opened with the key, the problem is most likely in the button mechanism or wiring. Let's look at how to diagnose and fix a problem without visiting a service center.

Required tools:

• 🔧 Screwdriver with Phillips bit (PH2)
• 🔧 Plastic spatulas for removing the panel
• 🔧 Multimeter (for checking contacts)
• 🔧 WD-40 or alcohol for cleaning
• 🔧 Heat shrink tube (in case of broken wires)

Step 1: Removing the button

Remove the decorative trim of the instrument panel (carefully pry it off with a spatula from the driver's door side). The trunk release button is usually secured with two latches or screws. Disconnect the wiring connector and inspect the contacts for oxidation or breaks.

Step 2: Diagnose the problem

Connect the multimeter in dialing mode to the contacts of the button. When pressed, a sound signal should be heard (the circuit is closed). If there is no signal, the problem is in the microswitch (replacement is required). If the circuit rings, but the trunk does not open, check the wiring from the button to the central locking control unit (located under the dashboard on the driver’s side).

Step 3: Cleaning and Repair

Clean the contacts with alcohol or WD-40, remove oxides with fine sandpaper (1000+ grit). If the plastic guide buttons are worn, lubricate them with silicone grease. If the wires are broken, restore the connection using soldering and heat shrinking.

Step 4: Reassembly

Reinstall the button, connect the connector and check operation. If the problem persists, it may be faulty trunk lock actuator (the motor that opens the lock). Its diagnosis requires removing the trunk door trim.

Replacing the trunk button: original vs analogues

If the button cannot be repaired, it will have to be replaced. For Nissan Tiida The hatchback fits both original parts and analogues from third-party manufacturers. Here's what you need to know before purchasing:

• 🔍 Original button (article 28521-4M000 or 28521-4M00A) costs from 1,200 to 2,500 rubles. Suitable for all modifications Tiida 2007–2013 The kit includes mounting clips and a seal.
• 🔍 Analogues from Denso or Mitsuba will cost 600–1,000 rubles. The quality is comparable to the original, but the warranty is shorter (6–12 months versus 2 years for official parts).
• 🔍 Universal buttons (for example, from Hella) are cheaper (300–500 rubles), but may not fit in terms of connector or size. Wiring needs modification.

Critical point: when buying an analogue, be sure to check the connector with the original. On Tiida 2011+ years use a 4-pin connector, and on pre-restyling models a 3-pin connector (without backlight). If you mix it up, the button will either not work or will burn out when connected.

Where to buy:

• 🛒 Official dealers Nissan (2 year warranty, but high price).
• 🛒 Online spare parts stores: Exist.ru, Autodoc, Emex (there is a filter by VIN code).
• 🛒 Disassembly (2-3 times cheaper, but without guarantee). Check functionality before purchasing!

⚠️ Attention: When replacing a button with an analogue one with a different pinout, do not connect the wires at random. A short circuit can damage the central locking control unit (repair cost starts from 5,000 rubles). Use the connection diagram from section below.

What to do if the trunk does not open: emergency methods

Situation: the button does not work, the key does not work, and there are important things in the trunk. Don't panic - in Nissan Tiida The hatchback has emergency opening methods.

Method 1. Mechanical lever inside the cabin

In most modifications Tiida behind the rear parcel shelf (under the trim) there is an emergency release cable or lever. To get to it:

1. Fold down the rear seats (the levers are located in the trunk near the backrests).
2. Remove the plastic plug on the rear shelf (it is secured with clips).
3. Find the cable with the red or orange handle and pull it down.

Method 2. Opening with a key through the lock on the trunk door

On some versions Tiida (especially pre-restyling ones) there is a hidden lock under the trunk handle. To open it:

1. Remove the plastic trim above the license plate (it is secured with 2-3 clips).
2. Under the trim you will see a hole for the key - insert and turn counterclockwise.

Method 3. Powered directly from the battery

If the problem is in the electronics (for example, the battery is dead or the fuse is blown), you can supply power to the lock actuator directly:

1. Remove the trunk door trim (screwdriver PH2).
2. Locate the actuator connector (usually black or gray, with 2 wires).
3. Connect to the 12V terminals from the battery (for a short time!). The lock should work.

What to do if none of the methods helped?

If the trunk does not open even using emergency methods, the reason may be a mechanical locking of the lock (for example, after an accident or corrosion). In this case, the intervention of a car mechanic will be required. Do not try to drill out the lock - this will lead to expensive door repairs.

Retraining the key after replacing the battery or button

If the trunk button on the key stops working after replacing the battery, resetting the terminals or installing a new button, you need it retrain. This procedure synchronizes the remote control with the central locking control unit.

Instructions for Nissan Tiida 2007–2013:

1. Close all doors and trunk.
2. Insert the key into the ignition and turn to position ON (do not start the engine).
3. Within 5 seconds, press the central locking button on the key 6 times (with an interval of no more than 1 second).
4. Turn off the ignition and remove the key. The buttons should work.

If the procedure does not work:

• Repeat the steps, holding the trunk button on the key for 2 seconds on the sixth press.
• Check the battery charge in the key (if it is low, relearning is not possible).
• If the key does not synchronize, the control unit may be faulty (diagnosis with a scanner is required).

💡

Relearning the key resets all previously programmed remotes. After the procedure, you will have to rebind all the keys (maximum 4 pieces).

Prevention of breakdowns: how to extend the life of the trunk button

So that the trunk button is on Nissan Tiida lasted longer, follow simple recommendations:

• 🚿 Avoid moisture — after washing, check whether water is leaking through the trunk door seals. Oxidation of contacts is the main cause of breakdowns.
• 🧴 Lubricate the mechanism once a year with silicone grease (do not use WD-40 - it dries out and sticks!).
• 🔋 Keep an eye on your battery — at low voltage (less than 11.5V), the central locking electronics are unstable.
• 🔑 Do not press the button too hard — plastic guides crack over time.

If you often transport heavy loads, check the fastening of the trunk lock cable - it may fray or come off the guides. It is also useful to clean the button contacts on the instrument panel once every six months (just remove it and blow it with compressed air).

What to do in winter:

• Before frost, treat the trunk lock liquid silicone lubricant (not graphite!).
• If the button sticks in the cold, warm it up with a hairdryer (do not overheat the plastic!).
• Do not use hot water to defrost the lock - this will lead to corrosion.
