The remote start by key FOB is only possible (authorized) after the first successful start using the phone app. 2. Remote Door Lock/Unlock Preconditions and Tips: Utilize the following table as a guide to successful operation of the control apps (cell phone) based door lock and unlock system. NOTE: Network/cellular coverage may influence response time from each command. Sending multiple commands in a short period of time is not recommended.

Vehicle ECU Initializations: Ensure the vehicle settings and initializations for door lock and remote engine starter are correct as per the repair manual. A. Make sure that “Communication Remote Engine Starter” in Techstream customized settings that is designed/intended for an add-on or aftermarket RES kit is set to “Not Available”. Customize>Others>Communication Remote Engine Starter > Not Available EXAMPLE: B. With the related DTCs cleared, perform the following registrations/initializations: i. Smart Key Live>ECU Communication ID Registration>Remote Engine Starter ii. Smart Key Live>ECU Communication ID Registration> I.D. Code Box/Steering Lock iii. Telematics>Remote Door Lock Setting NOTES: If settings are improper, related DTCs may include: B126A, B2779, U0198, and U1117. Performing these specific “initializations” can be safely done even if not needed. Make sure the Telematics initialization utility includes the words “door lock” as a general “initialization” titled utility may be unrelated and not supporting the door lock/unlock app. Make sure that any customized setting for remote door locks has the feature enabled. Do NOT use the Telematics “activation” utility for existing DCMs with established accounts. [This is only for new off-the-shelf DCMs when first installed into vehicles.] 4. Key FOB Remote Start Operation: Once the remote start from the key FOB is functioning after telematics enrollment and remote authorization, it should continue to operate even if the customer allows the remote services trial to lapse and not renew.
