/en/qa/tag/rf-all Powered by Question2Answer /en/qa/87189/rf642w-will-not-start-2010-tahoe I have a really odd problem, I installed an EVO-ALL with GMT4 T-harness in a 2010 Tahoe and added a RF642W remote kit.  I can start the vehicle with 3X Lock, but not with the RF642W.  I have the RF kit option H2 selected, I got the visual on the EVO-ALL and the blue blinking light on the RF antenna that my remotes got paired with the EVO-ALL, but they still do not work.  just for the heck of it I changed it to option H1 and was able to start the vehicle with the lock button on the RF642W, but was unable to shut the vehicle back off.  I am not sure why I can not get any reaction from the my RF642W remote with the option H2 selected.  Also, this vehicle also had a factory remote start installed, I douibt that has anything to do with it but just thought I would let you know.  Any ideas?
