Negative Response During Key Programming

WARNING: This page is about a different car, the 2020 Fiat 124 Spider. However, it is still accessible from the selected car via links, so may be relevant.

This occurs when the RFH is partially unlocked. This can be caused by performing the key programming procedure incorrectly. Follow the steps below to resolve.

  1. Navigate to the Powertrain Control Module (PCM) and select the "Misc Functions" tab.
  2. Select "PCM/RFH Replace".
  3. You will be asked to enter a PIN. This is the same PIN you retrieved in Dealerconnect on Step 1 of the Add Key procedure. Unlike the key fob programing, all vehicles will require the seven minute delay prior to the procedure being completed.
  4. Once the "PCM/RFH Replace" procedure is complete, the RFH will be unlocked. You can now continue programming a key fob starting with Step 2 of the Add Key procedure.
