Step-by-Step Programming Instructions
Follow these instructions carefully to successfully program your 2008 Toyota Sequoia key fob:
Preparation
- Ensure your 2008 Toyota Sequoia is turned off and the key is removed from the ignition.
- Open the driver’s side door.
- Make sure all other doors are closed and locked.
- The driver’s door should be unlocked.
Initial Key Insertion
- Insert your key into the ignition switch.
- Immediately pull the key out of the ignition. Do not turn the key at any point during this step.
Lock/Unlock Cycle – Round 1
- Within 40 seconds of removing the key, use the power lock switch located on the driver’s side door panel.
- Perform five lock/unlock cycles, starting with the lock action.
- Maintain a consistent pace, aiming for approximately one cycle per second (one cycle equals one lock and one unlock).
- After the five lock/unlock cycles, close and then open the driver’s side door.
Lock/Unlock Cycle & Ignition – Round 2
- Within 40 seconds of opening the driver’s door, use the power lock switch again to perform five lock/unlock cycles, starting with the lock action, at the same pace as before.
- Immediately insert the key into the ignition cylinder.
- Turn the ignition key to the ON position (just before starting the engine). Do not start the engine.
- Turn the ignition key back to the OFF position.
- Remove the key from the ignition.
Programming Mode Confirmation
- Within 3 seconds of removing the key from the ignition, the power door locks should automatically cycle (lock then unlock).
- This automatic door lock cycle indicates that you have successfully entered programming mode.
- If the door locks do not cycle at this point, return to Step 1 and repeat the entire process carefully.
Remote Programming
- Within 40 seconds of the door locks cycling automatically, take your new key fob remote.
- Press and hold both the lock and unlock buttons on the remote simultaneously for 1 second.
- Immediately after releasing both buttons, press and hold only the lock button for 2 seconds.
- Within 3 seconds, the door locks should cycle once. This single cycle confirms that the remote has been successfully programmed.
- If the door locks do not cycle, or if they cycle twice, repeat steps 1-4 in this “Remote Programming” section, as your remote may not have been accepted.
- To program additional remotes, repeat steps 1-4 in this “Remote Programming” section for each new remote you wish to program.
Completion
- Close the driver’s side door.
- Test each programmed key fob to ensure they are working correctly by locking and unlocking your 2008 Toyota Sequoia remotely.
By following these steps, you should be able to easily program your new key fob for your 2008 Toyota Sequoia. If you encounter any issues, double-check each step and ensure you are within the time limits specified.
