Symptom: The installer is unable to program the bypass kit's onboard transponder into the vehicle's BCM (Body Control Module).

Cause: In the majorority of these cases the remote starter timing is not fast enough to enable the vehicle's ignition and the bypass kit's transponder output so the vehicle's BCM times-out in the middle of the installation programming procedure.

Solution: The vehicle and bypass kit will need to be 'hot-wired' near the end of the programming sequence in order to enable the Bypass kit's output before the BCM times-out. In most cases (referring to most bypass kit programming procedure) once the second key has been removed the vehicle's ignition will need to be powered up and the bypass kit's ground-out-while-running input will need to be grounded. In some cases the vehicle's 2nd ignition or accessory wire will also need to be powered up and furthermore on very select few models the key sense wire will also need to be grounded.
