Why Did This Happen?

Car radios have built-in anti-theft systems that activate when power is interrupted. This prevents thieves from using stolen radios in other vehicles. The system locks when:

  • Battery disconnected or replaced - Most common cause (dead battery, new battery installation)
  • Battery terminals cleaned - Power interruption triggers lock
  • Fuse replaced - Radio fuse change causes reset
  • Electrical work performed - Any work requiring battery disconnect
  • Jump start with wrong polarity - Can trigger radio lock
  • Long-term storage - Battery drain over time

Step-by-Step: How to Unlock Your Radio

📋 Complete Process:

  1. Find Your Radio Serial Number

    Check radio label, press buttons 1+6, or check car documents

  2. Order Your Radio Code

    Enter serial on our dashboard - INSTANT for VW/Audi/Skoda/SEAT/Nissan

  3. Receive Your Code

    5 minutes (INSTANT brands) or 5-60 min (Mercedes)

  4. Enter Code in Radio

    Use preset buttons to input 4-digit code

  5. Radio Unlocked!

    Radio works normally - drive and enjoy music again

How to Enter Radio Code (Universal Method)

Once you have your 4-digit code (example: 1234), enter it using radio preset buttons:

  1. Turn on ignition and radio - Display shows "SAFE" or "CODE"
  2. Press button 1 repeatedly until first digit appears
  3. Press button 2 repeatedly until second digit appears
  4. Press button 3 repeatedly until third digit appears
  5. Press button 4 repeatedly until fourth digit appears
  6. Press and hold button 5 or 6 to confirm (some models: press "OK")
  7. Radio unlocks immediately!

⚠️ Important:

You have 10 attempts maximum. After 10 wrong codes, radio enters "SAFE 2" mode and locks for 1-2 hours. Always verify your serial number is correct before ordering!

Before ordering a code, check these free options:

1. Check Car Documents

Owner's manual, service booklet, or radio code card in glove box

Will disconnecting battery again reset the radio?

Yes, radio will lock again. Write down your code and keep it safe! Or save it in your phone/glove box.

Can I unlock radio without the code?

No safe way. Attempting to bypass the security system can damage your radio permanently. Always use the official code.

How many times can I use the same code?

Unlimited! Once you have the code, you can use it every time your radio locks. Keep it safe.
