Step-by-Step Guide to Program Your 2002 Toyota 4Runner Key Fob
Follow these steps carefully to program your remote.
Preparation
Before you begin, ensure the following conditions are met:
- You are inside your 2002 Toyota 4Runner.
- The key is removed from the ignition.
- The driver’s side door is open, and all other doors are closed.
- The driver’s door is unlocked. Other door locks do not matter.
Programming Steps
Perform these steps within the given time limits for successful programming:
-
Key Insertion: Insert your key into the ignition, and then immediately pull it out. Do not turn the ignition on.
-
Lock Cycling and Door Action (within 40 seconds):
a. Cycle the power door locks five times using the power lock switch on the driver’s door. Do this at a reasonably fast and even pace.
b. Close and then open the driver’s side door. -
Lock Cycling and Ignition Sequence (within 40 seconds):
a. Cycle the power door locks five more times, just like in the previous step.
b. Turn the ignition key to the ON position, then immediately back to the OFF position.
c. Repeat the previous step one more time: Turn the ignition to ON, then back to OFF.
d. Remove the key completely from the ignition. -
Confirmation of Programming Mode: Within 3 seconds, the power door locks should automatically cycle (lock and then unlock). This indicates that you have successfully entered programming mode. If the locks do not cycle, return to step 1 and repeat the process.
-
Transmitter Programming (within 40 seconds):
a. Press and hold both the LOCK and UNLOCK buttons on the key fob transmitter simultaneously for 1 second.
b. Immediately after releasing both buttons, press and hold only the LOCK button for 2 seconds.
c. Within 3 seconds, the door locks should cycle once (LOCK then UNLOCK) to confirm successful programming of this key fob. If the locks do not cycle, or if they cycle twice, repeat steps 5a and 5b for this specific remote. This indicates the remote was not accepted. -
Programming Additional Transmitters: Repeat steps 5a and 5b for every key fob you need to program, including any existing remotes you want to continue using.
-
Final Step: Close the driver’s door.
Troubleshooting
If you encounter issues and the programming mode is not activated (locks don’t cycle in step 4), double-check that you have followed all the preconditions in the Preparation section and repeat the steps from the beginning.
