Before you begin, ensure you have your new, unprogrammed key fob for your 2008 Lexus RX 350. Follow these steps carefully to program your remote:

Key Insertion Sequence – Step 1: Within 5 seconds of opening the driver’s door, insert the key into the ignition and pull it out twice in quick succession.

Door Close and Open – Step 1: Immediately after removing the key the second time, close and then open the driver’s side door twice.
-
Key Insertion Sequence – Step 2: Insert the key into the ignition and then remove it once.
