How to open Daewoo Matiz without a key: from the trunk lock to the services of a car mechanic

Forgotten houses, lost or broken keys in the lock Daewoo Matiz block access to the car, especially when it comes to models M100 (1998–2005), M150 (2005–2011) or M200 (2011–2015) — their door mechanisms and locks require a special approach. Unlike cars with electronic access systems, you cannot do without mechanical impact, but with the right actions you can do without broken glass or a damaged lock.

In this article we will look at 7 working ways open Daewoo Matiz without a key - from simple (for example, through the trunk) to emergency (using improvised tools). Each method is accompanied step by step instructions, warnings about possible risks and complexity assessment. Important: some methods are only suitable for certain modifications - for example, for cars with central locking or without it. We will also tell you how to avoid damage to the body and electronics, and when it is better to call immediately car mechanic.

1. Opening through the trunk: the safest way

If you have Daewoo Matiz in the back hatchback (and this is most models), the trunk often becomes a “lifeline”. The thing is that the back door is on Matize connected to the salon via folding rear seat. This allows you to reach the front door opening mechanism from the inside.

How it works:

• 🔧 If the trunk is not locked, open it with a key (if the key is lost, but there is a duplicate) or a master key.
• 🪑 Fold the back seat - on most Matizov it folds forward, freeing passage into the salon.
• 🚪 Place your hand over the front door lock lever (usually located next to the driver's side door release handle).
• 🔓 Pull the lever up or towards you - the door will unlock.

⚠️ Attention: On models M200 (2011–2015) with electric locks This method may not work if the battery is low. In this case, you will have to first light the car or use another method.

2. Using a wire or "ruler": driver's door method

A classic method that works on most older cars, including Daewoo Matiz M100/M150. The idea is to insert a flexible tool (wire, plastic ruler or even an unbent hanger) between the door and the body to press mechanical lock button inside the cabin.

Step by step instructions:

1. Take a wire with a diameter 2–3 mm (a bicycle cable or antenna cable will do). Make a small hook at the end.
2. Pull back the top corner of the driver's side door (where the glass meets the weatherstrip). To do this, you can use a flathead screwdriver wrapped in a cloth to avoid scratching the paint.
3. Insert the wire into the slot and guide it down towards the locking mechanism. On Matize it is approximately at the level 10–15 cm from the top edge of the door.
4. Hook the lock button or lever and pull up. If you hear a click, the door is unlocked.

Critical nuance: on models with electric windows (optional for M150/M200) there is less room for maneuver - you will have to act more carefully so as not to catch the glass mechanism.

3. Disassembling the door panel: for the patient and careful

If the previous methods do not work, you can try removing the inner door trim to get to the lock mechanism. This method takes time and care, but allows you to open the car no damage.

What you will need:

• 🔧 A screwdriver with a flat blade (or a special tool for removing clips).
• 🔦 Flashlight - lighting is required, as the mounts may be hidden.
• 🧲 Magnet - so as not to lose the fastening clips.

Procedure:

1. Remove the decorative trim on the door handle (usually it is secured with latches).
2. Unscrew the screws hidden under the cover (on Matize there are usually 2–3 pieces).
3. Carefully pry up the door panel trim, starting from the bottom corner. The clips are fragile - do not pull too hard!
4. When the trim is removed, you will see the lock mechanism. Pull the cable or press the locking lever manually.

⚠️ Attention: On models M200 with electric locks It may be necessary to disconnect the battery terminal (if it is discharged and is blocking the mechanism). Only do this if you are confident in your skills - unplugging it incorrectly may reset your settings ECU.

Model Matiz	Difficulty in disassembling the panel	Time (approx.)	Risk of damage
M100 (1998–2005)	Low (3–4 clips)	10–15 minutes	Minimum
M150 (2005–2011)	Medium (5 clips + screws)	15–20 minutes	Medium (risk of breaking clips)
M200 (2011–2015)	High (electronics, 6+ mounts)	25–30 minutes	High (may touch wiring)

4. Emergency methods: when all else fails

If all the previous methods did not work, and the keys are needed urgently, you will have to resort to more radical measures. It is important to understand that these methods can damage your vehicle, so only use them as a last resort.

Options:

• 🔨 Breaking glass. On Matize cheapest to replace - rear side window (cost of a new one: from 3 000 ₽). Before breaking, cover the glass with tape to prevent fragments from scattering throughout the cabin.
• 🔧 Drilling the lock. If the key breaks inside the cylinder, you can drill it with a drill with a thin drill bit (3–4 mm). After this, the lock will have to be replaced (price of a new one: from 1 500 ₽).
• 🚗 Towing to a mechanic. If the car needs to be moved urgently, order a tow truck or towing (the service will cost 1 000–2 500 ₽ depending on the region).

What to do if the alarm goes off?

If the alarm goes off when you open the door, don't panic. Try:

1. Insert the key into the ignition (if you get to the interior) - on many Matizah this turns off the siren.

2. Press the button Valet (usually hidden under the dashboard or in the glove compartment).

3. If the alarm is not standard, look for the control unit - it is often located behind the dashboard. Disable it by removing the battery terminal (but this will reset all settings!).

5. Professional help: when to call a specialist

If you are not confident in your abilities or are afraid of damaging your car, the best way out is to call car mechanic or lock picking service. Specialists use professional tools (for example, car master keys or pneumatic wedges), which reduce the risk of damage to a minimum.

How much does it cost?

• 💰 Opening the door without damage: 1 500–3 000 ₽.
• 🔑 Making a duplicate key for a lock: 2 000–4 000 ₽ (depending on the key type).
• 🔧 Replacing the lock cylinder: 3 000–6 000 ₽ (with work).

6. How to avoid problems in the future

To no longer find yourself in a situation where the keys to Matiz lost or forgotten, follow these simple rules:

Preventive measures:

• 🔑 Duplicate key. Always keep the spare key in a safe place (for example, in magnetic box under the car or from loved ones).
• 📱 Electronic key. For models M200 can be installed keyless entry (set price: from 8 000 ₽).
• 🔋 Battery monitoring. A discharged battery can block the central locking. Check the charge every 2–3 months.
• 📋 Documents for the car. Keep copies PTS and STS in cloud storage - this will speed up the production of new keys.

FAQ: Frequently asked questions about opening Daewoo Matiz without a key

Is it possible to open Matiz without a key if the trunk lock is broken?

Yes, but it's more complicated. Try:

1. Remove the rear light (it is secured with 2-3 screws) and insert your hand into the hole towards the locking mechanism.
2. Use a wire through the gap between the trunk and the body (similar to the door method).
3. If the trunk is on electric drive, connect the power directly to the battery (electrical skills required!).

⚠️ On M200 The rear bumper often interferes with access - you will have to partially dismantle it.

What to do if the key in the ignition switch is broken?

Do not try to remove the fragment yourself - this may damage the larva. Better:

• Lubricate the lock WD-40 or silicone grease.
• Carefully pick up the fragment with thin pliers or extractor for broken keys.
• If it doesn't help, call a locksmith. Cost of retrieving the wreckage: 1 000–2 000 ₽.

How to open Matiz if the battery is dead and the central locking does not work?

There are two options:

1. Mechanical: use wire or disassemble the door panel (see sections 2 and 3).
2. Electric: connect donor battery or starter charger directly to the terminals under the hood. After this, the central locking should unlock.

⚠️ On M150/M200 with immobilizer may be required key retraining after disconnecting the battery.

Will the wire method work on a Matiz with tint?

Yes, but it will be more difficult. Tinting reduces the visibility of the locking mechanism, therefore:

• Use narrow beam flashlightto highlight the gap.
• Take flexible wire (for example, from an antenna) - it bends better at the desired angle.
• If the tint is very dark, try the method with disassembling the door panel.

Is it possible to insure risks when opening a Matiz?

Yes, if you have a policy CASCO with option "Emergency Commissioner". Many insurance companies (eg. Ingosstrakh, RESO) include the service in the contract car opening if you lose your keys. The cost of the technician’s visit in this case is covered by insurance.

Check with your insurer:

• Is autopsy included in your policy?
• What is the payout limit (usually 3 000–5 000 ₽).
• Do I need to keep receipts from the locksmith for compensation?
