Radio Code

[Karl K]

Hi,

I have an 2001 RX 300 and need to replace the battery. I don't have the radio code.

What are my options?

Thanks.

Use the last 4 digits of the VIN.

If a code has never been applied No code is needed. There is no code from the factory.....

And it is the last 4 digits from the KEY code.

If you have one of those portable jump starters with a cigarette lighter adapter you can plug it into the cigarette lighter and turn the key on but don't start it up. When you disconnect the battery terminals make sure that you cover them as not to short the Positive side to ground and it should save your codes and your ECU memory.

Thanks guys, for the fast replies. I am new here and apreciate the help. The portable jumpstarter sounds like a great idea.

Thanks again.

I don't understand. If power has been disconnected the radio should require a code. How would you ever apply a code if one is never needed?

Interesting point about the key code. My RX is 6 1/2 years old and still going strong on the original battery. I asked the dealer at one time, expecting to change the battery as a preventative measure last winter, how to determine the radio code. I was told it's the last-four of the VIN. I still haven't changed the battery so I do not know which of us is right. Have you actually tried the last-four of the key code?

I haven't changed the battery yet but I have to soon. This thing is confusing. Not knowing if a code was ever put in I don't want to take a chance. If the last four digits of the VIN are used and everyone knows it, so does the thieve who is not supposed to know the code. Is't that what a code is for?

I think I am going to modify the system by adding a standby battery. All I have to do is find the color coding on the wiring at the fuse box.
