SERVICE INFORMATION
This bulletin is being issued to inform dealers that some of the replacement remote keyless entry (RKE) key fobs under P/N 15186203 may not synchronize with the vehicle after following the procedure highlighted in the SI Document ID #660745. It has been found that the key fob software may be set in a new mode, which can cause a lack of synchronization. To exit the new mode, hold the unlock and panic alarm buttons simultaneously for ten seconds. This will place the key fob software in a learnable mode for individual truck synchronization. Next, complete the synchronization process as per the SI document. DO NOT dispose or return the inoperative key fobs until this procedure has been first attempted.
