My battery died, so I needed to jump start my battery. When my car started again, my screen was asking for a four digit password. I think I entered the wrong number in one too many times, so now the...

  • You can try to disconnect the battery again for 5 minutes and then reconnecting it and see if that brings your screen back up. If it does not then your radio has gone into PUK mode. PUK mode is what happens when the wrong code is entered to many times. It's a lock that can only be overridden by contacting the manufacturer of your radio. This is a security feature. Good luck.

My Toyotas battery went flat so now the radio is not working, it is displaying "SEC". I need to put in a 3 digit code. I do not know what the previous/old code is, so that I can cancel it and...

This is a security code that is specific to that radio for anti-theft reasons it comes up every time that radio loses power. It should be written in your manual or there should be a radio card that you received with the car that has the code on it. If you can't find this you're going to have to pull out the radio and get the serial number off of it and contact the toyota dealership for the security code.

My battery went out when it snowed and when i tried to get a jump it knock the radio out and now all it says it code it there a code for the radio or is it fried

I suspect that when you jumped it, the leads were perhaps reversed momentairly by accident and the theft deterrant chip in the radio got wiped. That chip holds the information necessary to instruct your radio how to operate, and if say some thief stole your radio that chip would erase itself after being away from the battery for 30 minutes. I suspect that your battery may have completely gone flat and the radio chip erased itself, if the reversal did not happen. That chip can be reprogrammed, but it has to be done by the dealer, as they are the only ones who are supposed to have the equipment to program the chip. It cost 25-50 bucks to have it done.

If you have to replace your battery, connect a nine volt battery between the battery connectors if the battery replacement is going to take longer than 30 minutes. This will hold the memory in your computer as well as the radio.

My radio on my 2007 chevrolet aveo stop working. It is dead. It is like there is no power.

This happened to me and the next time I beeped the horn the radio came back on. Then for a long time radio would only come on if you beeped the horn. Battery has since gone dead, when I jumped it the radio now works fine. I am convinced wires are crossed and radio still sucks juice from the batttery even when the car is off. Battery stays charged and starts car if you make sure radio is off before shutting car off for the night. Am taking it to the dealer a.s.a.p. So long story short see what happens when you beep the horn.

Radio wouldn't work after the battery went flat and had to start the car from another car

check the radio fuse and the cig lighter fuse and if you have a second 12 outlet check that fuse also. most of the time thats the problem some time the deck can go bad after a car battery dies but hardly.

Delco factory radio display is saying loc

There is a code. This usually happens when the battery dies, when you disconnect the radio or disconnect the battery. Unfortunately only the dealer or delco repair shop can unlock it.
have a great day!

Radio sound stopped

You may have blown the fuse in the fuseholder for the radio power when jumping. Follow any wiores that come off the battery terminals and trace them to a fuse. Check that fuse and replace if needed. Also check fuse on back of radio.
