Anyone seen these?

I picked one up from harbor frieght with a similar design as it was under $10.00.

I need to work on my aribag system and I would like to disconnect the battery. Although I dont have my radio code...

Think this will work?

I am sure it will work. Unless you have a car that switches off the lighter with the key. But my A4, that isn't the case.

I just realized my radio has never locked my out...I have a 2000, but I'm not sure if that matters...huh, wonder if the 99's are different,. good luck with that!

you can disable the lockout feature.

How do you disable the lockout feature??

good question, I'm sure the info is out there some where. It came disabled on my car so I've never really looked in to it.

It would be cool if I could disable the lockout.

I read that the 9v maintainers can be bad for the ECU, and possibly ignite the airbags though. I am not sure why or how.. I am a little worried abou using it now.

Best bet would be to disable the lockout and disconnect the battery.

Any one know how?

I really don't think that is possible. Shouldn't ignite the air bags nor should it be bad for the ECU. Like I said, as long as the key isn't in the ignition and on then you won't get betting any power to those systems. Therefore the 9V battery will have NO effect on either of the two.

Cool. Sounds good.

The only question is, will it acutally keep the radio out of safe mode..?
