trunk Nissan Almera Classic (in the B10 body, also known as Samsung SM3 in some countries) is one of those parts that seems simple until it stops working as intended. Owners often encounter problems: the button on the key does not work, the lock is jammed, or the mechanical opening cable is broken. In this article we will look at all possible ways to open the trunk - from standard to emergency, and also tell you how to avoid breakdowns in the future.

Feature Almera Classic is that its trunk can be locked both electrically (via the central locking) and mechanically. This means that even if the battery is dead or the remote control is broken, you still have a chance of success. The main thing is to know where to look for hidden levers and how to properly manipulate the lock without damaging it. We have collected instructions that are suitable for models 2006–2012, as well as for restyled versions with a redesigned rear door.

1. Standard methods of opening the trunk

Let's start with the most obvious methods, which should work in 90% of cases. If your Nissan Almera Classic is working, one of these methods will definitely help.

Method 1: Button on the key. On the original keychain Almera Classic there is a separate button with an image of an open trunk (usually located at the bottom). Press it once - if the central locking is working, the trunk will open. If the button does not respond, check the battery in the remote control: even with a low car battery, the key fob should give a signal at a distance of up to 5 meters.

Method 2: Button in the cabin. Next to the driver's seat, on the panel to the left of the steering wheel, there is a small button with a similar symbol. It duplicates the function of the key fob and also controls the electric drive of the lock. If the button does not press or “falls through,” the spring may have broken—in this case, only disassembling the panel will help.

  • 🔑 Check the battery in the key: Even if the car starts, the weak signal may not reach the trunk antenna.
  • 🚗 Try opening it from the passenger side: Sometimes the central locking antenna picks up the signal better on the right.
  • 🔄 Press the button twice: on some versions Almera Classic The first signal will unlock the doors, and the second will unlock the trunk.

Method 3: Mechanical key. In the trunk lock Almera Classic There is a hole for a physical key - it is hidden under a plastic plug to the right of the handle. Carefully pry off the plug with a flathead screwdriver, insert the key and turn counterclockwise. If the lock does not turn, do not force it: the mechanism may be rusty or jammed.

Method 4: Emergency opening cable. B Nissan Almera Classic There is a cable that allows you to open the trunk from the passenger compartment. It is located behind the rear parcel shelf (if you have a sedan) or under the door trim (for hatchbacks). To get to it:

  1. Fold down the rear seat (if possible) or remove the trim panel under the window sill.
  2. Find the plastic hatch with the inscription EMERGENCY or a red ring.
  3. Pull the cable down - this will unlock the lock.

Attention! If the cable is torn or missing (this happens after unqualified repairs), do not try to pull the pieces - this may damage the lock mechanism. In this case, proceed to the next method.

Method 5: Disassembling the trunk trim. If all the previous methods did not work, you will have to remove the inner panel of the trunk door. To do this:

  • 🔧 Unscrew the two screws under the closing handle (they are hidden under the decorative plugs).
  • 🕳️ Carefully pry up the trim around the perimeter, starting from the bottom corner.
  • 🔍 Find the lock mechanism and manually slide the latch (it is usually plastic, white or gray).

⚠️ Attention: When disassembling the trim, do not use sharp objects - you can damage the heated glass wiring or parking sensors (if installed). If you are not confident in your abilities, it is better to contact the service.
