Chevrolet Spark Radio Code — Unlock It Online
Your Chevrolet Spark radio is showing a code prompt after a battery change, flat battery, or any power interruption. It's a common situation — and the fix is straightforward. This guide explains how to find your radio's serial number, get the correct unlock code, and enter it so your stereo starts working again.
Why Does the Chevrolet Spark Radio Lock?
Chevrolet (and its predecessor Daewoo, which underpinned the early Spark models) equips its factory radios with an anti-theft protection system. Any interruption to the power supply — a new battery, a flat battery, or the removal of the radio unit — causes the system to lock. The radio displays CODE and won't operate until the correct unlock code is entered. The code is unique to each unit's serial number and is required to restore normal function.
Finding the Serial Number on a Chevrolet Spark Radio
Method 1: Button Combination
- Switch the ignition on so the radio powers up (it should display CODE).
- Press and hold preset buttons 1 and 6 simultaneously for two to three seconds.
- The serial number will appear on the display. It is typically an alphanumeric string of eight or more characters.
- Note it down precisely, including any letters at the start.
Method 2: Physical Label
- Using DIN extraction tools, release the head unit from the dashboard and slide it partially out.
- Look on the casing — top, side, or rear — for a white sticker bearing the serial number and barcode.
- Record the number exactly as printed.

Entering the Code on a Chevrolet Spark
- Power the radio on so it displays CODE.
- Use the preset buttons (1 to 4) to enter each digit of the code. Each press of the button increments the digit for that position.
- Once all four digits are set correctly, confirm the code by pressing the seek or scroll button (sometimes labelled with an arrow or the number 5).
- The radio should unlock and begin operating normally.
Chevrolet Spark Generations: What You Need to Know
| Generation | Platform Code | Years | Market Notes | Typical Radio Type |
|---|---|---|---|---|
| Spark I | M200 | 2005–2010 | Sold as Matiz in some markets; built on Daewoo Matiz II platform | OEM AM/FM/CD, basic cassette on early examples |
| Spark II | M300 | 2010–2015 | Fully revised; also sold as Daewoo Matiz Creative in some regions | OEM CD/MP3, some with Bluetooth |
The M200 generation shares its platform heritage with the Daewoo Matiz II and uses similar radio security procedures. The M300 brought a fresh design and updated electronics, but the fundamental radio unlocking process remained consistent across both generations.
Troubleshooting Chevrolet Spark Radio Problems
The display shows WAIT after I entered a wrong code
After incorrect code entries, most Chevrolet Spark radios enter a timed lockout. Turn the ignition off and wait at least one hour. After the wait period, the radio should allow another attempt. Do not try to guess the code — each wrong entry extends the lockout.
I see ERR on the display
ERR confirms the code entered was incorrect. The most common cause is a misread serial number. Double-check the serial — pay attention to characters that look similar, such as 0 (zero) vs O (letter O), and 1 (one) vs I (letter I). Then re-order with the corrected serial number.
The radio shows LOCKED and won't accept a new code attempt
A permanently locked state (as opposed to a timed lockout) means too many wrong codes were entered. At this point, the unit typically requires a dealer or specialist to reset it using diagnostic equipment.
My Spark was imported — will the code process work the same way?
Yes. Radio codes are tied to the serial number of the physical unit, not the country of registration. The procedure is identical regardless of where the car was originally sold.
The radio has no display at all
Before assuming a radio issue, check the fuse for the radio circuit. A blown fuse will prevent the radio from powering up entirely, making code entry impossible until it is replaced.
Frequently Asked Questions
Is the Chevrolet Spark radio the same as the Daewoo Matiz radio?
The M200 Spark (2005–2010) is closely related to the Daewoo Matiz II and the radios may share the same security algorithm. The serial number lookup process is the same for both.
How long does it take to receive the unlock code?
After you submit the serial number through our online service, the code is typically emailed to you within minutes. The service is available 24 hours a day, seven days a week.
Do I need the code again after every battery change?
Yes — any power interruption will trigger the radio lock. Keep your code in a safe place outside the vehicle so you can re-enter it quickly whenever needed.
Can a Chevrolet dealer provide the code?
Since Chevrolet's withdrawal from European markets, dealer support can be limited. Our online service can retrieve codes from the serial number without needing any link to manufacturer records.
