I have a 2008 Prius with an after-market HomeLink mirror. For almost 1 1/2 years it has worked fine, but starting yesterday the arm would not go up on the gate at my subdivision. Other residents could enter just fine, so something is wrong with the signal between my HomeLink and the arm. This same HomeLink also works my garage door opener just fine. The gate company can't see any problem (of course), so they are asking me to re-program the gate code. Question: if I can figure out how to re-program the gate code, will this mess up the garage door process? Thanks.
