Damage to the trunk release mechanism on a car Nissan Almera Classic - This is a common problem that many owners of this model face. Over time, the cable drive stretches, and the plastic bushings of the mechanism wear out, making it impossible to open the cover from the inside or outside. This is especially acute in winter, when the mechanism freezes or jams due to dirt and lack of lubrication.
Operating a car with a broken lock creates serious inconvenience, turning a simple trip to the store into a complex logistical task. You'll either have to open the trunk through the cabin by crawling through the rear seats, or resort to drastic measures to access the space behind the rear seat. Timely diagnosis and replacement of the trunk lock Nissan Almera Classic will allow you to avoid expensive body repairs and restore the ease of use of the car.
The main reasons for failure of the trunk lock
The most common cause of mechanism failure on the model Nissan Almera Classic is wear on the lock drive cable. The cable connecting the opening handle in the interior with the lock itself stretches over time, and its tension becomes insufficient to operate the latch. In this case, when you press the lever, you do not feel resistance, and the lid remains tightly closed.
Another common problem is corrosion and contamination of the inside of the mechanism. trunk lock. In the conditions of Russian roads, where reagents are used, the metal part of the lock quickly becomes covered with a layer of rust and dirt. This leads to the fact that the moving elements stop moving freely, and the mechanism jams even with a working cable.
Sometimes the problem lies not in the lock itself, but in the plastic opening handle located on the trunk lid. Brittle plastic may crack or break when exposed to low temperatures or mechanical force. In this case, the lever simply scrolls idle, without transmitting force to the drive cable.
It is also worth noting that on some copies Nissan Almera Classic There are factory defects in the assembly of the mechanism when the bushings are installed skewed. This accelerates the wear of the rubbing pairs and leads to rapid failure of the unit. The most critical situation occurs when the cable is frayed inside the protective braid, which requires a complete replacement of the drive.
Diagnosis of faults and selection of spare parts
Before purchasing a new unit, it is necessary to accurately determine the nature of the failure. First, try opening the trunk by pressing the lever in the cabin, and at the same time ask someone to press the button on the trunk lid. If the mechanism is triggered by external influence, but not by the internal lever, the problem is definitely in the cable or interior handle.
If the lock does not open on either side, most likely the problem is in the latch mechanism itself or its jamming. In this case, you will need to remove the trunk lid trim for a visual inspection. Pay special attention to the condition lock cylinders and plastic clips.
When choosing spare parts for Nissan Almera Classic You have two options: purchase an original lock or choose a high-quality analogue. The original part (OEM number often starts with 80xxx) is expensive, but guarantees an exact match of all fasteners and durability. Alternative options from brands like Masuma or Kaga may be cheaper, but their quality often leaves much to be desired.
The table below shows comparative characteristics of popular lock options for this model:
| Part type | Average cost | Service life | Compatibility |
|---|---|---|---|
| Original (Nissan) | 8,000 - 12,000 rub. | 5+ years | 100% |
| Analogue (Masuma) | 3,500 - 5,000 rub. | 2-3 years | 95% |
| Analogue (Kaga) | 2,500 - 3,500 rub. | 1-2 years | 90% |
| Used from disassembly | 1,000 - 2,000 rub. | Unpredictable | 100% |
⚠️ Attention: Do not buy the cheapest Chinese analogues without a brand, as they often do not have the necessary backlashes for correct operation, which leads to distortion of the mechanism after the first winter.
Preparation for dismantling and necessary tools
The process of replacing the trunk lock with Nissan Almera Classic does not require sophisticated equipment, but accuracy is key here. You will need a set of screwdrivers: a flat head for prying up the clips, a Phillips head for unscrewing the bolts, and a 10 or 12 mm socket wrench. Also prepare new lubricant for the mechanism, it is best to use silicone or lithium.
Before starting work, you must disconnect the battery terminal to avoid a short circuit when disconnecting the electrical connectors if your lock has an electric drive or an opening sensor. This is a standard safety precaution for any work on vehicle electrical systems.
You will also need a plastic spatula to remove the trim to avoid damaging the decorative plastic or scratching the paintwork. If you don't have such a spatula, you can use an old plastic card wrapped in soft cloth.

Step-by-step instructions for replacing the lock
You need to start work by removing the trunk lid trim. Unscrew all visible screws, usually they are located under the plastic plugs in the handle area and at the bottom along the perimeter. Carefully pry the clips around the perimeter of the trim and remove it, without using excessive force so as not to break the fasteners.
After removing the trim, you will have access to the lock mechanism. Disconnect the drive cable by pressing the lock on the end of the cable. Be careful, the spring may spring back sharply. Then unscrew the three nuts securing the lock itself to the body from the inside of the cover.
Pull the old lock out through the service hole in the lid. At this point, it is important to carefully disconnect all electrical connectors, if any. Install the new lock in the reverse order, after lubricating all moving parts. Make sure the cable is properly tensioned and not twisted.
Before final assembly, check the operation of the mechanism. Ask an assistant to press the handle in the interior while you watch the latch operate. If the mechanism works smoothly, you can begin to install the casing back.
☑️ Preparing to replace the lock
⚠️ Attention: When installing the cable, make sure that it is not bent at a sharp angle, as this will cause it to wear out quickly and break again in the near future.
What to do if the lock is jammed tightly?
If the lock is jammed and the trunk will not open, you can try carefully inserting a flat-head screwdriver through the gap between the lid and the body to release the latch. However, this is a risky method, as it can damage the paintwork or the mechanism itself. A safer option is to remove the rear seat and get to the lock from inside the cabin by unscrewing the bolts securing the lock through a hole in the upholstery.
Troubleshooting lock cylinder problems
Sometimes the problem lies not in the lock mechanism itself, but in the cylinder (cylinder) that is responsible for opening it with the key. If the key turns with difficulty or does not turn at all, the cylinder must be lubricated or replaced. To do this, you need to remove the decorative trim on the trunk lid and unscrew the locking screw of the cylinder.
Before replacing, try treating the cylinder with a penetrating lubricant, such as WD-40, and turning the key several times. If this does not help, you will have to remove the larva and replace it with a new one. It is important to choose a cylinder that matches your key, or recode it to fit an existing key.
When installing a new cylinder, make sure that it fits tightly in its seat and does not play. Any loose movement may result in the mechanism not operating when the key is turned. Also check the condition of the plastic bushing on which the cylinder rotates.
Before removing the lock cylinder, take a photograph of its position relative to the body so that during reassembly you do not confuse the orientation and damage the mechanism.
Setting up and adjusting the mechanism
After installing a new lock, it may need to be adjusted. Sometimes the trunk lid closes too tightly or, conversely, does not lock completely. To adjust, you need to loosen the bolts securing the latch to the body and move it slightly in the desired direction.
If the lid is difficult to close, move the latch closer to the center of the car. If it does not lock, move it to the side opposite the center. After each movement, tighten the bolts and check the operation of the lock.
Also pay attention to the rubber stops (buffers) on the body. If they protrude too much, they may prevent the lid from closing tightly. In this case, they can be shortened a little or pressed inward. A properly adjusted lock should close with a characteristic click and not let water into the interior.
Adjusting the position of the latch is the final step, which ensures that the trunk lid fits snugly and there is no vibration when the car is moving.
