Is your 2002 Toyota 4runner Key Fob no longer working, or did you get a replacement that needs programming? Don’t worry, you can program your key fob yourself without a trip to the dealership. This guide provides easy-to-follow instructions to get your 2002 Toyota 4Runner key fob programmed and working in no time.
Step-by-Step Programming Guide for Your 2002 Toyota 4Runner Key Fob
Follow these steps carefully to program your key fob. Ensure you perform each step accurately and within the specified timeframes for successful programming.
Step 1: Initial Conditions
Before you begin, make sure of the following:
a. The key is out of the ignition.
b. The driver’s side door is open.
c. All other doors are closed.
d. The driver’s door is unlocked.
Step 2: Key Insertion
Insert your key into the ignition, and then immediately pull it back out. Do not turn the key on at this stage.
Step 3: First Lock Cycle Sequence
Within 40 seconds of removing the key, perform the following:
a. 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.
b. Close and then open the driver’s side door one time.
Step 4: Second Lock and Ignition Sequence
Within 40 seconds of completing Step 3, execute these actions:
a. Cycle the power door locks five more times, again at a consistent and moderately fast pace.
b. Turn the ignition key to the “ON” position, then immediately turn it back to the “OFF” position.
c. Repeat the previous step one more time: Turn the ignition to “ON” and then back to “OFF”.
d. Remove the key completely from the ignition.
Step 5: Confirmation of Programming Mode
Within 3 seconds after removing the key from the ignition in Step 4d, the power door locks should automatically cycle (lock then unlock). This automatic cycling indicates that you have successfully entered the key fob programming mode. If the locks do not cycle at this point, return to Step 1 and repeat the process.
Step 6: Transmitter Programming
Now you are ready to program your 2002 Toyota 4Runner key fob transmitter. Complete these steps within 40 seconds:
a. Press and hold both the LOCK and UNLOCK buttons on the key fob transmitter simultaneously for approximately one second.
b. Immediately after releasing both buttons, press and hold only the LOCK button for about two seconds. Within three seconds, the door locks should cycle once (LOCK then UNLOCK) to confirm successful programming of that transmitter. If the door locks do not cycle, or if they cycle twice, it means the remote was not accepted. In this case, repeat steps 6a and 6b for that specific remote.
c. If you have additional key fobs (including any old ones you wish to continue using), repeat steps 6a and 6b for each transmitter you want to program.
Step 7: Final Step
Close the driver’s side door. This action will finalize the programming sequence. Test each programmed key fob to ensure it correctly operates the door locks and other keyless entry functions on your 2002 Toyota 4Runner.
By following these instructions, you should be able to easily program your 2002 Toyota 4Runner key fob. Enjoy the convenience of your working keyless entry system!
