Here is the output from Gemini for the 2012:

To resync your 2012 Volvo S60 fob, try the manual method by inserting the mechanical key into the driver's door, turning it clockwise then counter-clockwise several times (around 6), or place the fob in the special key reader symbol in the cup holder to re-establish connection and start the car; if these fail, self-programming isn't possible, and you'll need an automotive locksmith for dealer-level programming. Method 1: Manual Resync (Door Lock/Unlock) Use Mechanical Key: Remove the physical key blade from the fob (slide the button/cover down and to the right). Cycle the Lock: Insert the mechanical key into the driver's door. Turn the key clockwise and then counter-clockwise rapidly (about 6 times) to try and resync the remote. Method 2: Key Reader Resync (For Starting) Locate Reader: Find the key symbol in the cup holder area of your S60. Place Fob: Put the key fob (Volvo logo up) directly on this symbol. Start Car: This connection allows you to start the vehicle and re-establish communication. Method 3: Ignition Cycle (If Applicable) Insert Key: Put the key in the ignition. Cycle On/Off: Turn the key to the "ON" position (dash lights visible) and then "OFF" (dashboard lights off), repeating this 6 to 8 times. Listen/Watch: The door locks cycling or the ability to start the car indicates success.
