Lost your key fob or bought a replacement for your 2002 Toyota 4Runner? No need to rush to a dealership and spend a fortune. Programming a new key fob for your 2002 4Runner can be done right in your driveway with a few simple steps. This guide will walk you through the process, ensuring you can regain keyless entry convenience quickly and easily.
Step-by-Step Guide to Program Your 2002 Toyota 4Runner Key Fob
Before you begin, make sure you have all your key fobs that you want to program for your 4Runner, as you’ll need to program them all at the same time. Here are the conditions you need to meet before starting the programming sequence:
- You are inside your 2002 Toyota 4Runner.
- The key is out of the ignition.
- The driver’s side door is open, and all other doors are closed.
- The driver’s door is unlocked. The status of other door locks does not matter.
Once you have confirmed these conditions, follow these steps closely:
-
Initiate the Programming Sequence: Insert your key into the ignition, and then immediately remove it. Do not turn the key on.
-
Lock Cycle and Door Action (Within 40 Seconds):
- Cycle the power door locks five times using the power lock switch on the driver’s side door panel. Maintain a consistent, relatively fast pace for these cycles.
- After the fifth lock cycle, close and then open the driver’s side door.
-
Second Lock Cycle and Ignition Sequence (Within 40 Seconds):
- Cycle the power door locks another five times, again using the power lock switch and maintaining the same pace as before.
- Turn the ignition key to the “ON” position, and then immediately back to the “OFF” position.
- Repeat the previous step: Turn the ignition key to the “ON” position again, and then immediately back to the “OFF” position.
- Remove the key completely from the ignition.
-
Confirmation of Programming Mode: Within 3 seconds of removing the key, the power door locks should automatically cycle once. This lock cycle indicates that your 2002 Toyota 4Runner has successfully entered programming mode. If the locks do not cycle, return to step 1 and repeat the process carefully.
-
Transmitter Programming (Within 40 Seconds):
- Take the first key fob you want to program. Simultaneously press and hold both the “LOCK” and “UNLOCK” buttons for one second.
- Immediately after releasing both buttons, press and hold the “LOCK” button alone for two seconds.
- Within 3 seconds, the door locks should cycle once (LOCK then UNLOCK) to confirm successful programming of that key fob. If the door locks do not cycle, or if they cycle twice, it indicates that the remote was not accepted. In this case, repeat steps 5a and 5b for that specific remote.
- Repeat steps 5a and 5b for every additional key fob you need to program, including any existing remotes you were previously using. It’s crucial to reprogram all remotes at the same time to ensure they all function correctly.
-
Final Step: Close the driver’s side door. This action should finalize the programming sequence.
Congratulations! You have now successfully programmed your 2002 Toyota 4Runner key fob. Test each key fob to ensure it correctly locks and unlocks your doors. By following these steps, you’ve saved yourself time and money while regaining the convenience of keyless entry for your Toyota 4Runner.
