It seems like everyday someone is writing in with the problem of loosing
the radio code or having changed a battery and now their radio comes up
with "safe" or "code".
the registered owner of the vehicle
needs to call the dealer and with the V.I.N. # ready for them (and in some cases,
the radio serial number) to get the serial number of the radio it will have to be removed in some cases and in other it can be brought up on the screen of the radio. the dealer will know this and how to advise you to do so. request the code and procedure. Once you have
this code and procedure, write the code and steps down in the owners
handbook or other item that stays with the vehicle.
no master code that works for all radios. how it works is the dealer has a computer program that will generate the code from the serial # inputed into it. so each radio has it's own unique code.
hope this helps everyone with this issue , for you will have saved the code
and have it handy for that next battery change.
The procedure for clearing the code is below, but first you must understand that you must have the remote to do this procedure. Kenwood has designed these radios so that the only way to clear the code is by using the remote. I know this because I work at an authorized Kenwood service center and have done this procedure many times.
If you do not have a remote, or you can not buy or borrow one, the only other way to clear the code would be to take it to an authorized Kenwood service center and they will do it for a small fee. The shop I work at charges $25 for this, but it is up to each shop as to how much they want to charge.
Here is the procedure:
1. While “– – – –” is being displayed, press [ >>I ] key for at least 3 seconds while pressing [AUTO] key. This makes “– – – –” display disappear.
2. Using the remote controller, input “KCAR”.
Press remote controller  key 2 times (Input for “K”) and then press [ >>I ] key.
Press remote controller  key 3 times (Input for “C”) and then press [ >>I ] key.
Press remote controller  key once (Input for “A”) and then press [ >>I ] key.
Press remote controller  key 2 times (Input for “R”) and then press [ >>I ] key.
3. The security is released and the unit enters the STANDBY mode.
4. If a wrong code is input, the unit goes into the Code Request mode.
Since this is the only way and it is the correct way to clear the code, I would very much appreciate a FixYa! rating. It is the only reward we get for offering people like yourself this free information.
Let me know if you need any further help, like needing to know where you can buy a remote or whatever other questions you may have.
You need to leave you radio with pwr on for about 60 to 90 minutes,then the display will show CODE and you can try again,if you don't have the right code or nobody hasn't programmed any code try this number which is a master code for this model code 0100
A volvo dealer can look up your radio code if you provide the VIN. The problem is that then you have to follow the instructions in your user's manual to actually input the code, and the manual seems to be a poor translation from Swedish to English.
So you have to get a Volvo dealer in a headlock and force the correct instructions out of them. If you do this before I do, please let me know!
