Hello,
Radios have a theft-proof system that freezes the radio if
power is
interrupted. It was designed that way to prevent theft of the radio. The
downside is your radio will be locked if you disconnect the
battery for any reason, or if the battery dies.
When you restore power, it will say ‘CODE‘ on the
display.
Take care.
Thanks jumuah,
Yes, I can enter the code, but it is not accepted.
I've read that if you add 1212 to the last 4 digits of your serial, which in my case is 1403, giving a code of 2615, which matches the code stated in the car's paperwork. Might be useful for you if someone has lost their pin but has the serial in the future.
I guess it must just be a problem with the stereo itself, but I was hoping there was a way around it (like a magic master code or something). I will take it to an car audio electrician tomorrow to see what can be done.
first I used a flexible blade to pry off the black plastic frame... then, I used two metal rulers as the slides on either side and a screw driver under the unit to pry it loose so I could grab the unit with my fingers and slide it towards me. Getting to see that serial number (top right corner of stereo - just under bar code) isn't easy though as the unit doesn't come all the way out -- it helps to have somebody around to write the serial number as you peer into the darkness and read it out. Then, I added 1.2.1.2 (in that order) to the last four s/n digits (example: 6724 + 1212 = 7936) to get the code (7936) that unlocked my stere and saved me $90 (Hyundai dealer's proposed charges).

Im having the same problem! Everything described i have tried. Nasties at Hyundai dont help. I just want my radio back
I had the exact same problem as you and equally Hyundai customer service
(not the nice people from Hyundai who actually attempted to fix the
problem with me) said there must be a problem with the unit and that I
should take it to be repaired.
Well, that's not the problem.
There is no problem with your head unit. It is Hyundai who are at fault.
They never tested their original pincode in the first place. So they do
not even know the correct pincode. The serial number is correct,
however the serial number does not provide the pincode despite what
Hyundai say. Reply back if anyone needs further details from me.

Hi Adam, I have the exact same problem! any luck?? I have no idea what to do I have tried everything
Security code chip was fried and couldn't be repaired unless it was taken back to Hyundai. Had to get a new stereo in the end.
Oh.. how annoying is that. Okay no worries adam, thanks for your help :)
The electrician I took it to said that the security chip in it was fried and that it couldn't be fixed because Hyundai won't supply the replacement part.
