WE'LL FIND THE RIGHT CALCULATOR.
You do not need to know who manufactured your radio. Find the serial number, enter what you see below, and DUBB45 will point you to the correct calculator.
FIND MY CALCULATOR ↓FIND YOUR SERIAL NUMBER
Look for SERIAL, S/N, or a code beginning with letters such as TM9, T0MYD, T00BE, TxxQN, or TxxAA. It may be in the radio settings or printed on the radio label.
TYPE WHAT YOU SEE
Paste the whole serial if you have it. The finder only uses the serial pattern to choose the correct calculator.

The large red characters are what matter. You don't have to identify the radio by appearance.

Take a clear photo of the radio sticker or send the full serial and part number. We'll help you choose the correct calculator instead of guessing.
BEFORE YOU START
Where do I find the radio serial number?
Check Settings → System Information first. If it is not displayed, the OEM label is normally on the top, side, bottom, or rear of the radio chassis.
Are these calculators actually free?
Yes. DUBB45's listed radio-code calculators are free to use with no account, credit card, or software installation.
Why did my radio suddenly ask for a code?
This commonly happens after battery replacement, a dead battery, power loss, radio removal, radio replacement, or installation of a used unit.
Should I keep trying codes if one doesn't work?
No. Verify the serial and calculator type before repeated attempts. Some radios enter a timed lockout after incorrect codes.
