Program 2007 Remote Transponder Key
 

Does anyone know how to program a remote transponder key for 2007 Camry LE? The kind of key with the four buttons on it. Local dealership wants to charge me $116. I already have the new key cut and it opens all the appropriate locks and turns the car over but will not start due to the immobilizer. Found a and tried that process but it did not work.

Who can save me $116??
