How to Take Apart a Buick Key Fob that Has a Metal Key

  • Press the button that pops out the mechanical key. Depending on the type of key fob you have, this may be a chrome rectangle on the back or a round chrome button on the front.
  • If your key fob has a removable metal key, pull the metal key completely out while pressing down on the button. Skip this step if your key fob does not have a removable metal key.
  • If your key fob has a removable metal key, use the metal key to pry open the key fob case. If the key is not the removable type, use a small flat head screwdriver to pry open the case.
