A radio unlock code, also known as an anti-theft code is a unique numeric unlock key that restores access to your car stereo after it has been locked.
This factory security PIN is triggered when the radio is disconnected from power.
Car manufacturers use this security system to prevent stolen radios from being reused.
If power is interrupted, the radio stops functioning and requires the unlock CODE before it can function normally.
Once the valid numbers combination is entered, the stereo is restored to normal operation.

Exception: 2013-2014 Honda Odyssey and Pilot models do NOT require a radio code. All other Honda and Acura models do require the anti-theft code after power loss. Your 4-digit or 5-digit code is permanently linked to your radio's unique serial number.
Start by inspecting the vehicle handbook. The code is often found on a detachable slip or written directly on a dedicated panel.
You can also search the glovebox or trunk, where dealers or previous owners may have placed a sticker with the code. Some also search for it behind trim pieces or inside the fuse box.
If you have the original factory-issued code slip, that's the simplest place to find the code - it usually includes both the serial number and unlock key.
There are a few options - but they depend on your situation.
