Can you post (or PM) your car VIN, the radio serial number and the security code you tried? We could check if the three match, perhaps the radio isn't original and your code is incorrect.
It typically takes 15 minutes before you can enter the code again if wait first appears after 3 incorrect code entry attempts. But this time gets longer if the code is again entered incorrectly three times. Eventually some radios need 24 hours for a new attempt. Would be easier to remove the radio from the car and power it up from a good lab power source, no need to keep the car ignition on for hours.
