/en/qa/tag/ex-one Powered by Question2Answer /en/qa/123001/ex-one-was-just-working-now-it-doesnt-and-wont-program Bought a 2015 Tacoma where the Ex-one didn&#039;t work. I diagnosed as a split wire, repaired the wire, programmed the fobs, and got it to work. On and Off, Door Lock and everything worked. Then I unplugged it to run it through my dash, and once everything was back together, now nothing works. I can&#039;t even press the valet/programming button to enter programming mode. When I turn the key in the ignition, the yellow light comes on, but that&#039;s it. I have tried touching a paperclip to both valet switch terminals to check if it&#039;s the button that is malfunctioning but the red light still never goes on.<br /> <br /> What would cause the whole box to suddenly stop working??<br /> <br /> Again, I try to press the valet button, and the red light never comes on to progress through programming mode. Is there a button combination on the fobs? Or a factory reset on the receiver that I can push with a pin? Have I accidentally put it into &quot;valet mode&quot; with a button combination?<br /> <br /> I do not have the manual because I bought the truck used, and there is no support on this website, and the Fortin troubleshooting app seems to be an incomplete app, where most buttons don&#039;t work, and on one screen where it asks me to choose a diagram, the only options are &quot;yes&quot; and &quot;no&quot;...
