Is your 1999 Toyota 4Runner key fob malfunctioning, or did you get a new remote and need to program it? Don’t worry, you can easily program your key fob yourself without a trip to the dealership. This guide provides simple, step-by-step instructions for programming your 1999 Toyota 4Runner key fob, saving you time and money.
Programming Procedure for your 1999 Toyota 4Runner Key Fob
Before you begin, ensure you have all the key fobs you wish to program for your vehicle. Follow these steps carefully for successful programming:
-
Prepare the Vehicle: Make sure all doors are closed and unlocked. Open only the driver’s side door.
-
Key Insertion Sequence (Part 1): Within 5 seconds, insert your key into the ignition cylinder (do not turn it) and immediately remove it. Repeat this insert and remove key cycle one more time.
-
Door Cycling & Key Insertion (Part 2): Within 40 seconds of step 2, close and then open the driver’s door. Repeat this close and open door cycle one more time. Insert the key into the ignition (again, do not turn it) and remove it.
-
Door Cycling & Ignition ON/OFF: Within 40 seconds of step 3, close and then open the driver’s door two times, just like in step 3. Now, insert the key into the ignition and leave it there. Close the driver’s door. Turn the ignition to the “ON” position, then immediately turn it back to the “OFF” position. Do not start the engine. Remove the key from the ignition.
-
Confirmation of Programming Mode: Within 3 seconds, you should hear the power door locks cycle (lock then unlock automatically). This indicates that your 4Runner has successfully entered programming mode. If the locks do not cycle, return to step 1 and repeat the process.
-
Remote Programming: Within 40 seconds of entering programming mode:
- Simultaneous Press: Press and hold both the “lock” and “unlock” buttons on the key fob simultaneously for about 1.5 seconds.
- Single Button Press: Immediately after releasing both buttons, press and hold only the “lock” button.
- Confirmation: Within 10 seconds, the door locks should cycle once (lock then unlock) to confirm successful programming of that remote. If the locks cycle twice, it indicates a programming failure. In this case, repeat steps 6A and 6B.
-
Program Additional Remotes: Repeat step 6 for each additional key fob you need to program.
-
Exit Programming Mode: Open the driver’s door. This action should exit the programming mode.
-
Test Your Remotes: Test all programmed key fobs to ensure they are working correctly with your 1999 Toyota 4Runner.
Alternate Programming Procedure
If the standard procedure doesn’t work, try this alternate method, ensuring you have all remotes ready:
- Close All Doors: Ensure all doors, including the back door, are fully closed.
- Open Driver’s Door: Open the driver’s side door only.
- Key Cycle: Insert the key into the ignition and then remove it immediately.
- Lock/Unlock Switch Cycle (5 Times): On the driver’s side door panel, locate the power door lock switch. Press the “LOCK” and “UNLOCK” buttons alternately at 1-second intervals, repeating this cycle 5 times.
- Close and Re-open Driver’s Door: Close and then re-open the driver’s door.
- Lock/Unlock Switch Cycle Again (5 Times): Repeat step 4 – Press the “LOCK” and “UNLOCK” buttons on the door panel alternately at 1-second intervals, 5 times.
- Insert Key: Insert the key into the ignition switch.
- Ignition ON/OFF: Turn the ignition to the “ON” position, then back to “OFF”. Do not start the engine.
- Remove Key: Remove the key from the ignition.
- Programming Mode Confirmation: The door locks should cycle to confirm entry into programming mode.
- Remote Activation: Press and hold the “LOCK” & “UNLOCK” buttons together for 1.5 seconds; then press and hold “LOCK” until the locks cycle once to confirm programming.
- Programming Confirmation: The locks should cycle once to confirm successful programming. If they cycle twice, the programming failed.
- Program Remaining Remotes: Repeat the button procedure in step 10 to program any remaining key fobs.
- Close Driver’s Door & Test: Close the driver’s door and test all programmed remotes.
By following these procedures, you should be able to program your 1999 Toyota 4Runner key fob quickly and efficiently. If you encounter issues, double-check each step and ensure you are within the specified time limits.
