Disassembly of the boot lock ŠKODA Fabia 2: instructions with photos and tips

Trunk lock on ŠKODA Fabia 2 (2007-2014 release) — a node that sooner or later requires attention: whether it is replacing the larva, cleaning the mechanism or eliminating the jamming. Many owners are afraid to disassemble this element on their own, for fear of damaging the wiring or plastic parts. However, with the right approach, the procedure takes no more than 30-40 minutes and does not require special skills.

In this article you will find step-by-step instructions with photos, a list of necessary tools, as well as common mistakes, which newcomers allow. We will figure out how to dismantle the skin of the trunk lid, disconnect the electrical wiring and remove the lock without risking damage. microswitch or lock-drive. We will pay special attention to the nuances for versions of the electric drive and mechanical lock.

Preparation: Tools and Safety Precautions

Before starting work, make sure you have everything you need on hand. Wrong tool - the main cause of broken clips and stripped bolts. Here's what you'll need:

• 🔧 10 mm socket wrench or socket - to unscrew the lock lock bolts.
• 🔨 Plastic puller or flathead screwdriver - for dismantling the skin (metal screwdriver can leave scratches!).
• ⚡ Multimeter If you need to check the electric drive circuit (optional).
• 📸 Smartphone for photography — fix the location of the wires and clips before disconnecting.
• 🧲 Magnetic pallet or bowl - so as not to lose small parts (springs, washers).

Important: if your Fabia 2 equipped remote-controlled central locking systembefore the disassembly disconnect the battery (with the negative terminal removed). This will prevent short circuits from accidentally closing the contacts. For mechanical locks, this is not necessary, but is recommended for safety.

⚠️ Attention: On models with electric-powered (optional 3Z6 837 015) the radio and on-board computer settings may be reset after the battery is disconnected. Write down the codes in advance or prepare instructions for their recovery.

Removing the trunk lid trim

The casing is attached to plastic clips and two bolts (under decorative stubs). To take it off:

1. Open the trunk and Keep the lid in the open position. (Ask for help or help with your work).
2. Remove decorative plugs The stains are on the sleeves (the sleeves). Put a flat screwdriver on them.
3. Unscrew two bolts Torx T25 (or Torx T30 on restyled versions).
4. Gently pull the trim towards you, starting at corners. The clips should come out with a characteristic click.

If the clips do not budge, do not use excessive force - they're easy to break. The cavity between the lining and metal of the trunk lid is often clogged with dust. When there is strong resistance, check if the edge of the skin is caught by the lock drive cable or lighting.

After removing the casing you will see:

• 🔌 Wiring connector (if the lock is electric).
• 🔗 Power-driven cable (For versions without electric drive).
• 🛠️ Two or three lock bolts (depending on the year of manufacture).

Disconnection of the wiring and the drive cable

At this stage the main thing is do not mix up the connectors And don't damage the wire insulation. If your castle electric, proceed like this:

1. Click on connector lock (usually black or gray) and carefully pull the pad from the nest. Don't pull the wires!
2. Check the contacts for availability oxidation or corrosion. Clean them if necessary WD-40 or contact spray.

For lock-lock:

1. Find tether-holder (usually white or yellow in color).
2. Clutch it with your fingers or pliers and pull the rope out of the groove.
3. If the cable is jammed, Don't pull him. - lubricate the connection silicone grease Try again in 5-10 minutes.

⚠️ Attention: On some Fabia 2 After 2012, the trunk lock drive cable is integrated with child safety blocker. When it is disconnected, the safety lock may work. F37 (10A) in the fuse block. If the lock does not work after assembly, check this fuse!

Where is the fuse box located?

On the ŠKODA Fabia 2, the fuse block is located to the left of the steering column, under a plastic cover. The F37 is responsible for the central lock chain and the backlight of the trunk.

Dismantling of the trunk lock: bolts and fastenings

The lock is attached to the trunk lid two or three bolts (depending on the configuration). Here's how to unscrew them:

Lock type	Number of bolts	Key size	Features
Mechanical (until 2010)	2	10 mm	Bolts can be boiling - use penetrating lubricant.
Electric (2010–2014)	3	10 mm + Torx T20	The third bolt is hidden under the plastic cover of the micro-switch.
Facelift (2012–2014)	3	10 mm	Bolts can have anti-corrosion coating – do not apply excessive force.

After unscrewing the bolts, the lock should easily exit the seat. If he "stuck"Don’t knock on it with a hammer – it can hurt. larva or microswitch. Instead:

• 🔧 Carefully tuck the lock with a flat screwdriver from different sides.
• 💧 Apply penetrating lubricant (for example, Liqui Moly LM-40) around the perimeter of the anchorage.
• ⏳ Wait 10-15 minutes and try again.

On the restyled versions of the Fabia 2 (after 2012), the trunk lock can be integrated with the opening sensor. When dismantling it, do not pull the sensor wires - this can tear off soldered contacts on the board!

Disassembly of the lock: larva, springs and micro-switch

If you need larva, clean the mechanism or check outThe lock needs to be disassembled. For this:

1. Place the lock on a clean surface (for example, on the white sheet of paperSo as not to lose the little details.
2. Remove plastic cover on the back, with a screwdriver.
3. Remove larval spring (They can fly out, hold your finger!)
4. To replace the larvae, press on retainer (usually a metal brace) and pull it out of the body.

When cleaning the mechanism, use:

• 🧴 Lock lubricant (for example, CRC 2-26 or Würth HHS-K).
• 🧹 A hard-pile brush to remove dirt.
• 🪛 Compressed air (Cylinder) to blow dust from hard-to-reach places.

If the castle does not lock in closed position, the problem may be:

• 🔄 A worn-out spring - it needs to be replaced.
• 🔧 Deformed fixator - try straightening it out with pliers.
• ⚡ Faulty micro-switch Check it with a multimeter (resistance should be 0-1 ohms in a closed state).

Installation of a new lock and reverse assembly

The assembly is performed in reverse order, but there are several critical points:

1. When installing electric lock First connect the wiring connector, then lock the lock with bolts. This will prevent the wires from being over-bending.
2. For mechanical lock First insert the cable into the groove, then secure the lock.
3. Check before fixing the skin. lock-work It should open/close smoothly, without creaking.

When the skin is installed:

• 🔧 Start with top clips Then, slowly, and slowly, pull it down.
• 🔊 You should hear flat-click If any angle is not fixed, check whether the wire or cable interferes.
• 🔩 Twisting the mounting bolts, but don't overtighten - this can deform the plastic.

⚠️ Attention: After assembly, check trunk tightness. If the skin is installed incorrectly, water can penetrate into the cabin through the seal. To check, pour the trunk lid with water from the hose and inspect the seal for leaks.

Common problems and their solutions

Even after proper disassembly and reassembly, malfunctions may occur. Here are the most common ones and how to eliminate them:

Problem	Possible reason	Solution
The lock won't open with the key.	The larva is jammed or worn out	Lubricate with graphite lubrication or replace the larva
The electric drive does not work with the key fob	Contact oxidation or wire breakage	Check the multimeter chain, clear the contacts
The castle opens but is not fixed.	The locking spring has broken or weakened	Replace the spring or the entire lock
Creak when opening/closing	Lack of lubrication or dirt ingress	Clean the mechanism and lubricate with silicone lubricant

If after replacing the lock The central castle has ceased to work., check:

• ⚡ Fuse F37 (10A) – it can burn when short circuit.
• 🔌 Connector connection Sometimes the contacts are not fully clicked.
• 📡 Set-up of the key fob After disconnecting the battery, reprogramming may be required (the instructions are in the manual to the machine).

FAQ: answers to frequently asked questions

Can I remove the trunk lock without removing the skin?

Technically no. The skin closes access to the lock mount bolts and wiring connectors. Attempts to reach the castle "blindly" lead to breakage of clips or damage to wires. The exception is if you only need to lubricate the larva (you can try to pour the lubricant through the slit, but the effect will be temporary).

What is the original trunk lock for Fabia 2?

Original articles depend on the year of manufacture and configuration:

• Mechanical lock: 6Y6 837 015 (before 2010) or 5J6 837 015 (after 2010).
• Electric lock: 3Z6 837 015 or 5J6 837 015 B (with a micro-switch).

Analogues: Febi Bilstein (number 27380), Hella (8GA 355 131-541).

What if the lock works after dismantling, but the trunk light bulb does not burn?

Most likely, when removing the skin was damaged. backlight connector Or the wire's broken. Check it out.

1. Integrity of the wire (often rubbed with a trunk loop).
2. Contacts in the connector -- they could have oxidized or moved away.
3. fuse F42 (5A) - he is responsible for lighting the trunk.

Can WD-40 be used to lubricate the lock?

Not recommended. WD-40 - this is water repellent liquidNot the lubricant. It will temporarily remove rust, but will not protect the mechanism from wear. For locks it is better to use:

• Graphite grease (for the maggot).
• Silicone grease (for springs and moving parts).
• Special lubricants type Liqui Moly Tischler-Fett.

How much does it cost to replace a trunk lock at a service center?

The cost of working in the car service depends on the region and type of lock:

• Mechanical lock: 1,500-2,500 rubles (excluding details).
• Electric lock: 2,500-4000 rubles (as wiring is required).

The castle itself will cost 3,000–6,000 rubles (original) or 1,500–3,000 rubles (analogue). Self-replacement This will save up to 70% of the cost.
