Removing the Škoda Octavia Tour door lock cylinder: instructions with nuances

Door lock Škoda Octavia Tour - a unit that sooner or later requires attention: be it a jammed mechanism, lost keys, or a planned replacement of a worn-out cylinder. Unlike salon work, where it is enough to remove the casing, dismantling the cylinder door lock requires accuracy and knowledge of the design features of the model. For example, on Octavia Tour In the pre-facelift version (2004–2013), the fastening of the cylinder is different from the facelift version (2013–2023), and incorrect handling of the fastener can lead to damage to the door or electrical wiring.

In this article - step-by-step algorithm removal of larvae taking into account generations Octavia Tour, a list of necessary tools, as well as unique pitfalls, about which even the official manuals are silent. For example, why on some versions an alarm may sound after dismantling the cylinder or how to avoid damage to the door sealing rubber. The material was prepared based on the experience of car mechanics and reviews of owners, so there is no “water” here - only specific actions and proven advice.

Preparation: Tools and Safety Precautions

Before you begin, make sure you have on hand:

• 🔧 Socket wrench by 10 mm (to remove the door handle on some versions)
• 🔨 Flat head screwdriver with a thin tip (for prying off clips and fasteners)
• 🔗 Wire hook or a special cylinder remover (for models with hidden fastening)
• 📸 Smartphone - to photograph the location of parts before dismantling
• 🧤 Gloves (optional, but recommended for protection from sharp metal edges)

Important: if your Octavia Tour equipped electric central locking, before starting work disconnect the negative terminal of the battery. This will prevent a short circuit if the wiring is accidentally touched. On models with keyless access (for example, Octavia Tour 3rd generation) after disconnecting the battery, it may be necessary key resynchronization - we will talk about this at the end of the article.

⚠️ Attention: On versions with electric windows after removing the door trim do not press the glass buttons - this can lead to distortion of the mechanism or breakage of the cable. If you need to lower the window, do it manually by gently pressing on it from above.

Step 1: Removing the Inner Door Trim

Sheathing on Octavia Tour attached to plastic clips and screws. Dismantling algorithm:

1. Remove decorative overlay on the door handle (pry it off with a flat-head screwdriver from the lock side). There is a screw hidden underneath that needs to be unscrewed.

2. Unscrew the screws hidden under armrest (on some versions they are hidden under plugs).

3. Carefully pry up the trim around the perimeter, starting from the bottom corner. The clips are fragile - if you pull too hard they will break.

On Octavia Tour 2nd generation (2004–2013) under the trim you will find moisture protection film. It needs to be removed, but not torn - it protects the electrical wiring from condensation. If the film is damaged, replace it with a new one after assembly (order number: 1Z6 837 701 for the left door, 1Z6 837 702 - for the right one).

Step 2: Accessing the Lock Mechanism

After removing the trim, you will have a view of the inside of the door. Lock mechanism on Octavia Tour located at the bottom, next to the window lift rod. To get to the larva:

• 🔧 Unscrew two bolts, securing the lock mechanism to the metal frame of the door (10 mm socket wrench).
• 🔗 Disconnect cravingsconnecting the lock with the internal opening handle. It is attached to a plastic clip - you need to squeeze it with your fingers and pull it out.
• 📶 If your model is equipped electric central locking, unplug the power connector (usually it is black with a latch).

On Octavia Tour 3rd generation (2013–2020) the lock mechanism may be partially closed door reinforcement - a metal plate with holes. It doesn't have to be completely removed, but sometimes you need to loosen one of the bolts for easier access.

⚠️ Attention: On diesel versions Octavia Tour (for example, with an engine 1.9 TDI) there may be a fuel line in the door. It is located towards the back of the door and has black corrugated protection. Do not confuse it with the lock wiring and do not deform it!

What to do if the bolts are soured?

If the lock mounting bolts cannot be unscrewed due to corrosion, use penetrating lubricant (such as WD-40 or Liqui Moly MoS2-Spray). Apply it to the threads, wait 10-15 minutes, then try unscrewing again. If the bolt still does not budge, try heating it with a hair dryer (do not overheat - 60–80°C is enough). As a last resort, you will have to drill out the bolt and replace it with a new one (M6 thread, length 20 mm).

Step 3: Dismantling the lock cylinder

Now you have come to the most important stage. Larva on Octavia Tour attached to the lock mechanism using retainer (usually a metal pin or plastic stopper). The method of dismantling depends on the year of manufacture:

Generation Octavia Tour	Type of fastening of the larva	Removal tool	Features
1st (1996–2004)	Metal pin	Thin screwdriver or hook	The pin may rust - pre-treat with WD-40
2nd (2004–2013)	Plastic retainer	Pliers or special puller	The latch is fragile - do not use excessive force
3rd (2013–2020)	Spring stopper	Screwdriver with magnetic tip	The stopper may fly out - hold it with your hand
4th (2020–present)	Combined (pin + latch)	Larva removal kit VAG	Care is required - there is a risk of damaging the shock sensor

General algorithm:

1. Insert the key into the cylinder and turn it to position "open" (this will unlock the latch).

2. On the back of the mechanism, find locking pin (it may be hidden by a rubber cap).

3. Press the pin with a screwdriver or hook while simultaneously pulling the cylinder towards you. If it does not give in, slightly rock it left and right.

On Octavia Tour 4th generation the larva can be equipped microswitch, which signals the position of the key. When dismantling, do not pull the wires - disconnect the connector in advance.

Common mistakes and how to avoid them

Even experienced car owners make mistakes when removing the cylinder. Here are the most common:

• 🔧 Broken trim clips — if you pull the casing without first unscrewing all the screws, the plastic clips break. Solution: buy spare clips in advance (item number 1J1 868 249 for Octavia Tour 2).
• 🔌 Wiring damage — on models with an electric lock, the wires leading to the actuator are often broken. Solution: Before dismantling, photograph the location of the wires and mark the connectors.
• 🚪 Door jamming after assembly — if the lock rod is installed incorrectly, the door will not open from the inside. Solution: check the rod stroke before complete assembly.
• 🔑 Loss of larva retainer — a small pin or spring may fall out and get lost. Solution: work on a clean surface or use a magnet.

Pay special attention Octavia Tour with system KESSY (keyless entry). On these models, the lock cylinder is connected to immobilizer antennalocated in the door handle. If the antenna wiring is damaged, the car may not start. Before operation, check that the antenna connector (usually white) is disconnected.

💡

On Octavia Tour 3 FL (facelift 2017) the lock cylinder can be equipped shock sensor for signaling. If dismantled carelessly, it triggers falsely. To avoid this, disable the alarm via the on-board computer menu (Settings → Security → Alarm: Off.).

Installation of a new cylinder and reassembly

Before installing a new larva:

• 🔍 Check if it matches key code with a code on the new cylinder (usually indicated on the packaging). On Octavia Tour larvae with codes are used VW 1J2 837 001 (for models up to 2013) and 5Q0 837 001 (for new versions).
• 🛠️ Lubricate the mechanism of the new cylinder graphite lubricant (don't use WD-40 - it attracts dust).
• 🔄 Make sure retainer in place and not deformed.

Installation proceeds in reverse order:

1. Insert the cylinder into the lock mechanism until the latch clicks.

2. Check the operation of the key - it should turn smoothly, without jamming.

3. Connect the rod and electrical wiring (if any).

4. Reinstall the lock mechanism and secure with bolts.

5. Put the trim back in place, starting with the top clips.

After assembly, check:

• 🚗 Does it work? central locking from the remote control.
• 🔑 Does the door open key on both sides.
• 🔊 Are there any extraneous sounds when opening/closing (creaks, hedges).

On models with keyless access after disconnecting the battery it may be necessary key resynchronization. To do this:

1. Insert the key into the ignition.

2. Turn it to position ON (don't start the car).

3. Press and hold the button LOCK on the key for 5 seconds.

4. Wait for the audible alert - synchronization is complete.

What to do if the larva does not come off?

If the larva does not respond even after all the manipulations, the following reasons are possible:

Problem	Possible reason	Solution
The larva does not extend	The retainer is stuck due to corrosion.	Apply penetrating lubricant and gently tap the mechanism
The key won't turn	Mechanism wear or debris	Try another key or drill out the cylinder (as a last resort)
The cylinder rotates, but does not come out	The lock inside the mechanism is broken	Disassemble the lock mechanism to remove debris

If the larva completely jammed and does not respond to the key, you will have to resort to radical measures:

1. Remove the lock mechanism completely (as described above).

2. Clamp it in a vice and drill out the cylinder with a drill with a diameter of 6–8 mm. Start drilling from the bottom where the pins are located.

3. After drilling, remove the remaining cylinder and install a new one.

⚠️ Attention: On Octavia Tour with aluminum doors (for example, models RS or Scout) Do not use a drill with a diameter larger than 8 mm - this may weaken the door structure. It is better to contact the service for a careful opening.

FAQ: Frequently asked questions about removing the cylinder on the Škoda Octavia Tour

Is it possible to remove the cylinder without removing the door trim?

Theoretically yes, but only Octavia Tour 1st generation, where access to the cylinder lock is possible through a technological hole in the end of the door. On newer models, it is necessary to remove the trim - otherwise you will not get to the fastenings of the lock mechanism.

What lubricant should I use on the new larva?

Use graphite lubricant (for example, Liqui Moly Graphit-Spray) or special lubricant for locks (Abro Lock Ease). Do not use WD-40 or lithol - they attract dust and clog the mechanism over time.

What should I do if the central locking does not work after replacing the cylinder?

Most likely, you damaged the wiring or did not connect the actuator connector. Check:

• The integrity of the wires (especially the black and brown ones responsible for power supply).
• The connector is connected correctly to the actuator (it should click).
• fuse F37 (10A) in the fuse box - it is responsible for the central locking.

If the problem persists, check the central locking setting using a diagnostic scanner (for example, VCDS).

How do I know which grub is suitable for my Octavia Tour?

The larvae differ in:

• Model generation (before 2013 or after).
• Door type (driver, passenger, rear).
• The presence of a central lock (if there is one, the cylinder must have a connector for the actuator).

The most reliable way is to remove the old cylinder and compare its part number with the catalog ETKA or EPC. For example, for Octavia Tour 2 FL (facelift) the cylinder with the article number is suitable 1Z6 837 001 B.

Do I need to reprogram the keys after replacing the cylinder?

If you only replaced mechanical larva (without electronic chip), no reprogramming required. However, on models with KESSY or immobilizer The key may need to be synchronized with the new mechanism. To do this:

1. Insert the key into the ignition.
2. Turn it to position ON.
3. Click the button LOCK on the key and hold for 5 seconds.

If the key is not synchronized, contact the service to diagnose the immobilizer.
