how can i change my car battery without losing my radio connection?

Question

anti theft makes a code necessary to restart the radio. do not have, dealer cannot get without $60.

Answer 1

if your lighter outlet has power regardless of key position, use a jump-start box to connect to it. if your lighter has no power with key out, you can hook the jump-start directly to the battery cables with clamps. NEVER DISCONNECT BATTERY WITH IGNITION SWITCHED ON!! most new cars also interpret battery disconnection as a theft attempt and will disable the ignition system, so if you don't know what you are doing, PLEASE take your car to someone that does. I can tell you horror stories about people that disconnected a battery without using an external power source and the price they paid to re-set the system.

Answer 2

I had the same problem. I don't think there is anyway that you change your battery without losing the connection with the radio. I drive a Saturn. At my dealer they reset the Anti theft code for free. Sorry for your luck. Next time set the code to 1111.

Answer 3

depending on the make model year, etc of the car. Some cars require a 9 volt battery that connects into the cigarette lighter or acc outlet that saves your radios memory. It has been a while since I have actually seen this. You used to be able to buy such an item at your local auto parts store or off of the Mac, Snap on, Matco etc. tool truck. Otherwise just hook jumper wires to an accessory battery.

Answer 4

Tap into your power wire and connect to a side battery for the time you are changing out the car battery and then just disconnect it.

Answer 5

Iv'e seen a device that you plug into the lighter jack that has a transistor battery. I saw it a Wal Mart. It keeps the memory powered up.

Answer 6

Buy a jumper pack. They sell them almost everywhere now. No car should be without one. They sell smaller ones for a fair price, and they can really get you, or someone you are helping, out of a jam.
