Is your 2002 Toyota 4Runner key fob not working like it used to? Perhaps you’ve replaced the 2002 4runner Key Fob Battery and now it needs reprogramming, or maybe you’ve just got a new remote. Luckily, programming your key fob for your 2002 4Runner is a straightforward process you can do yourself right at home. This guide will walk you through each step to get your remote working again in no time.
Here’s how to program your 2002 4Runner key fob:
-
Prepare Your Vehicle: Ensure your 2002 4Runner is ready by turning the ignition OFF and opening the driver’s side door, leaving it unlocked.
-
Initiate Programming Mode – Step 1: Insert your key into the ignition, but do not turn it. Then, remove the key from the ignition.
-
Enter Programming Mode – Step 2 (within 40 seconds):
a. Use the power lock switch on the driver’s door to perform five lock/unlock cycles. Begin with locking the doors. Maintain a consistent rhythm, aiming for approximately one cycle per second (a cycle is one lock and one unlock).
b. Close and then reopen the driver’s door. -
Enter Programming Mode – Step 3 (within 40 seconds):
a. Again, use the power lock switch to perform five lock/unlock cycles, starting with lock, at a pace of about one cycle per second.
b. Insert the key back into the ignition.
c. Turn the ignition to the ON position (without starting the engine) and then back to the OFF position. Do this once if you want to keep your currently programmed remotes and add a new one. Do it twice to erase all existing remotes and program a new one. Doing it three times will check how many remotes are currently programmed. Performing this step five times will erase all programmed remotes.
d. Remove the key from the ignition. -
Programming Confirmation: Within 3 seconds, the power door locks should automatically cycle lock and unlock. This indicates that your 2002 4Runner has successfully entered programming mode.
-
Program Your Remote (within 40 seconds):
a. Press and hold both the LOCK and UNLOCK buttons on your remote simultaneously for one second.
b. Press and hold the LOCK button for two seconds. The door locks will cycle lock and unlock again, confirming that the remote has been successfully programmed. -
Program Additional Remotes: If you have more remotes to program, repeat steps 6a and 6b for each additional remote.
-
Exit Programming Mode: Simply close the driver’s door to exit the programming mode.
-
Test Your Remotes: Finally, test all of your programmed key fobs to ensure they are working correctly. Programming is now complete! You should now be able to lock and unlock your 2002 4Runner with your newly programmed remote, even after a 2002 4runner key fob battery replacement.
