When the battery is replaced, does the imobilizer retain it's code or does it have to be reprogramed? Can the battery be purchased at Radio Shack or must it be bought at a Porsche dealer? Does any one know the battery number? thanks Mike W

 

What battery are you talking about. The remote battery?

If the remote battery - no worries, just replace it and all is well.

Replacing the car battery also doesn't affect the imobilizer.

Thanks Skip I was talking about the immobilizer battery. Do you know where I can get one. thanks

 

Mike,

Replacing the battery inside the remote will not cause a loss of the code. The battery is available anywhere. Its the same one used in a lot of overhead garage door openers. I think the number is "A23".

I have had best service life from the Duracell brand for this application.

 

Thanks Mike I will pick one up today.
