After installing and properly programming my Evo one unit, in factory turn-key option, it appears to operate correctly for a short period of time. If the vehicle sits for any length of time it appears that the unit at some point deactivates and does not respond to the key pressing on the key FOB. All standard factory operations are functioning as they should, however the remote start does not. Disconnecting the car's battery does bring this back online for a period of time, however once more does revert to inoperable status. The car does not have a factory immobilizer, and from what I can determine all correct connections have been made. Thanks in advance!
