Frequently asked

How do I find my radio serial number?

Remove the radio from the dash and look for the OEM sticker on the top, side, bottom, or rear of the unit. Some radios also show the serial number in the settings or system information screen.

Are these calculators really free?

Yes. No account, no credit card, and no software install. The calculators run on the DUBB45 server and return your code through the page.

Why does my radio need a code?

Factory radios may lock after battery replacement, power loss, radio removal, radio replacement, or installing a used unit. The code resets the anti-theft lock.

What if my radio type is not listed?
