The only way to unlock the radio without you having a code is the Volvo service center. They have instrumentation that they attach through the computer brain and unlocks the radio.

connect a battery charger to it while the key is on

there is a security system that will call for a code if the battery goes dead or is changed out. call a volvo dealership with the vin # of you car and they may be able to get it with that..they may need the numbers of the radio which means pulling it out enough to read the #'s, and give both numbers to them and they can give you your code

If you do not have the code. look in owners manual some times it is written in there or there is a card with code on it. if not you need to go to a volvo dealer and they can get the code for you. You may have to pay them for it.

The SC-816 is made by MITSUBISHI and the code cannot be calculated for free from anywhere on the Internet.

Try your Volvo Main Dealer....or a Decoding service who will plug it into a laptop to read/recode the memory chip (EEPROM)

Howver many Volvo Dealers offer the code for free provided you can quote the car VIN number and the radio serial number

you have to go to a volvo dealer and they contact the manufacturer to get code

There is no default code, the are unique to the radio. You will have to go to the dealer to get this code.

Turn the ignition on 1st position. Engine off. Ensure headlights are off to avoid battery drain. Turn power to radio on, 'Off' appears. Leave like this for approx 2 hours. It should then ask you for the code again.

Call your Volvo dealer with the VIN number. They can give you the code and advise if you can reset it yourself or if you will have to take it in.
