2018 Buick Cascada Keyless Entry Remote Fob

Important Notice: The 2018 Buick Cascada offers two methods for programming smart key remotes. The first method is when you have two programmed keys, and the second method is when you have no programmed keys available.

Programming with Two Programmed Keys: To program a new key using two already programmed keys:

  • Step 1: Insert the original, already programmed key into the ignition and turn it to the ON/RUN position.
  • Step 2: Turn the key to the LOCK/OFF position, and remove it from the ignition.
  • Step 3: Quickly, within five seconds, insert the second original programmed key into the ignition and turn it to the ON/RUN position.
  • Step 4: Insert the new key to be programmed and turn it to the ON/RUN position within five seconds. The security light will turn off once the key is successfully programmed.
  • Step 5: To program additional keys, repeat Steps 1-5.

Programming Without Two Programmed Keys: If you do not have two programmed keys, follow this procedure to program the first key. This process will take approximately 30 minutes to complete. All keys you wish to program must be available during this procedure.

  • Step 1: Insert the new key into the ignition.
  • Step 2: Turn the key to the ON/RUN position. The security light will come on.
  • Step 3: Wait for 10 minutes until the security light turns off.
  • Step 4: Turn the ignition to the LOCK/OFF position.
  • Step 5: Repeat Steps 2-4 two more times. After the third cycle, turn the key to the ON/RUN position, and the key will be successfully programmed.
  • Step 6: Important: All previously programmed keys will no longer work with the vehicle after this procedure. These keys will need to be reprogrammed using the “Programming with Two Programmed Keys” method.
  • Step 7: To program the second key, turn the ignition to the OFF position, insert the second key, and turn it to the ON/RUN position.
  • Step 8: After both keys are programmed, any additional keys can be programmed by following the “Programming with Two Programmed Keys” procedure.
