2009 FOB Reprogram
 

One of two of my remote FOB's was working intermittently (lock and unlocking), decided to open the the sealed FOB with a razor blade and replaced the VL2020 battery. FOB still works for starting and driving but no longer has remote operation. Tried a few suggestions I found online: inserting and removing several times within 10 secs. Pressing start without starting engine, again several times. Anyone advice most appreciated. Thanks!
