Hi, I am new to the board... I had the battery replaced to my switchblade remote for a '98 a4 and the keyless entry has stopped working. The dealer told me I needed to have it reprogrammed for close to $100... I remember having to recode the remote a few years ago by using the valet key in the ignition and typing a code into the stereo. I've tried some of the procedures I found on other sites, but nothing has worked. Can anyone help? Thanks.
