Losing all your key fobs can be a stressful situation. Programming a new key fob when you don’t have an existing one requires specialized tools and knowledge. In most cases, it’s best to seek the help of a professional locksmith or dealership. However, here are the general steps involved:

4.3. Keyless Access Vehicles (All Keys Lost)

Wait: Wait for 10 minutes until the DIC reads “Press Engine Start Button Learn,” then press the ignition button. The DIC will again read “Remote Learn Pending. Please Wait.”
