key fob doesnt work at all when evo-one installed 2009 toyota venza

Question

installed evo-one and t-harness toy 1 on a 2009 toyota venza g-key and followed instructions but for some reason when I plug the evo-one in the key fobs wont work at all to unlock or lock car either if the car is running or not.

When I unplug the evo-one from wiring harness the key fob works fine any ideas much appreciated.

Thanks

Follow the Programming instructions carefully.   When you plug in the EVO make sure you have your keys 10 to 15 feet away from the car. So it doesn't see the transponder key.   Plug in the connections in the proper sequence.  Since you have tried to program it before, you may have to reset it, and start over.  Make sure your have the latest Software Update for your EVO.
