You will need the access code, its usually in your handbook if not try trhe dealership (they sometimes make a charge for it)

Nothing will happen until the countdown timer has finshed, though (that sorts out the fuse problem, if the timer is working the fuse is fine)

It does depend on the car make and the radio though, and if you have buttons on the radio, IF you do have buttons AND the number just input them, should work, IF not its a trip to the dealer and ask them to reset it for you (thats what I ended up doing, took 10 minutes, and a fiver)

Is it your car and your radio.Then you must have the code or as Boris says if we knew the model we may be able to help.

In the past there have been many people looking for codes ,and I bet some of them are not been particularly honest,just looking for codes for stolen radios,if your puker ,then good luck
It all depends on the make and model, but there should be a section regarding the radio in the vehicle handbook. If you change the battery you must always reset the stereo with the code.
What make is it?? and while its counting down you can't reset anything in this countdown mode... have you the 4 digit code for it?? e-mail me for help if you want ive just been all through this myself!!!
