To turn off the anti-theft radio system on a 1995 Hyundai Elantra, you typically need to enter the radio's security code. If you have the code, turn on the radio and follow the prompts to input it. If you don't have the code, you may need to consult the owner's manual or contact a Hyundai dealer for assistance, as they may require proof of ownership to help reset the system.
To set the radio code for a 2005 Hyundai Elantra, first ensure the vehicle is in the "On" or "Run" position without starting the engine.

If you don't have the code, you may need to consult your owner's manual or contact a Hyundai dealer for assistance.
