I HAVE A HM-5064A CD TURN RADIO DECK.WHICH I WAS TOLD THAT ITS A PHILPS.

Need to go to the dealer with your VIN number and proof of ownership if radio is factory installed. If aftermarket you need to contact the manufacturer.

Ok do the following to get the code to unlock the unit.
GM DELCO THEFTLOCK RADIO UNLOCK CODE:
1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down.
2. After doing step one and writing down the code, immediately press
the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over).
3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if
you're
calling for Chevy, Pontiac, Cadillac, etc... When you here him tell
you
to press "2" for Pontiac, press 206010 and hit the # key. He'll ask
you
for the 6 digit code that you've written down. Enter that and press
the
* key. He will then give you a code, and the option to get additional
4
digit codes, but one should be sufficient.
4. Follow the normal procedure in your owners manual for unlocking the
radio with your new code...press the hour set button on your radio
until
you get the first two numbers of the code, then press the minute set
button until you've entered the last two numbers. Immediately press
the
AM/FM button once the correct code is entered and the code SEC or
"secured" will be displayed on the display screen. Now, just turn the
radio on, and your ready to roll.
There is an additional step you can take to remove all codes from the
radio and start from scratch by entering your own personalized 4 digit
code so that it won't get you in a pickle again! Just repeat step 4
and
you should get a display screen that reads ---. This means the code is
out, and you can now program your own code. Of course, once you
receive
the 4 digit code from the GM recorded message, just keep it in a safe
place, because you can use that same code again and again should you
have any more problems with it in the future. Good luck, and yes, it
does work

Normally the Audio (Radio CODE) is noted in the owner's manual. If you don't have it, you must contact Hyundai Motor America and give them the Vehicle VIN number... they may then (possibly) be able to give you the CODE.

There is a 4 digit code that you must enter to get the radio working again. You should have a plastic credit card sized card with the 4 digit code printed on it; if you don't have this card and the number is not written down anywhere on the owner's manual then the number should be on the back of the radio itself. When you turn on the radio the info screen should ask you to enter a code.....if you can't find the code in any of the places I listed I believe you can get it from the dealer. Hope this helps!

You should be able to enter the 4 digit code via the radio. If the radio has been replaced, you may need to recover the radio's serial number: Porsche Boxster: Online Lost Radio Code Recovery Tool

Turn on radio - the word SAFE will appear in the display. Press th P.SCAN and RBDS buttons simultaneously and hold them down until "1000" lights up in the display.Release buttons.Do not, under no circumtances, continue holding them down or press them once again. This will cause the radio to consider the number 1000 to be the input code.Use station buttons 1,2,3,and 4 to enter the code number on your Radio Card. Use the button 1 to enter the first number 2 for the second number 3 for the third number and 4 for the last number.Once you have entered the code and it shows on the display,press the P.SCAN and RBDS buttons down again simultaneously and hold them down until the word SAFE appears in the display.Release buttons. Soon afterwards a frequency will be displayed.

if you can remove the radio and take down the radio chassis number i can generate the four figure code,but i need the RADIO chassis number and not the car one

Here is the answer to the best of my knowledge. This applies to any body that has the need to get the code from the dealership and requires to pull out the radio and look up the serial number. The process is very simple, just follow these steps and you'll be on your way to listening to your radio again. First of all don't think you need to unscrew anything. The wood panel sorounding your stereo snaps out by pulling on it or using a flat screw driver at the corners. Once you have taken the panel out, you can see that the radio is held in by 2 hooks. Push up and pull forward slightly. You don't have to pull out the entire radio because you can see the serial number on the top surface very easyly. Write down the number next to where it reads s/n. Once you have the serial number, call the local dealership and give them your serial number. They will in turn give you a four digit code number that you will enter on your radio. One thing to note is that if you have entered the wrong code number 3 times, your radio would lock up and it would read "OFF". To unlock it, simply park your veichle in a safe place and leave the radio on for about 1 hour (no engine running just click the ignition switch to operate the radio). After one hour, the radio resetes and will aks you again to enter the code. start entering one number at a time using the first 4 buttons. Example, if your code is 4538, you would push button 1 four times to get to the number 4, you would push button 2 five times to get to the number five and so on.. After you have entered the correct code, push the cd button and there you have it. I hope this helps.

I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:
