Hold the power button and the AS button until the display shows 10 SAFE, 9 SAFE, etc. If the display stays stuck on SAFE, this likely means that the radio code has been entered incorrectly 10 times in a row - we call this a "hard lock". Try leaving the ignition and radio on for at least an hour then press AS and the power button again. If the lock still hasn't cleared, the only way to bypass it is to physically take the radio to a specialist with the right hardware tools needed to reset the lock in the radio's EEPROM chip. However, this is a much more expensive process and it can sometimes work out cheaper to buy a new radio. For this reason you should get in touch with us as soon as possible instead of wasting your code entries.
