Lost your key fob or need to program a new one for your 2005 Toyota 4Runner? No need to rush to the dealership and spend a fortune. You can easily program your 2005 Toyota 4Runner key fob right in your driveway with a few simple steps. This guide provides two methods to program your remote, ensuring you get back on the road quickly and affordably.
Method 1: Standard 2005 Toyota 4Runner Key Fob Programming Procedure
This is the primary method for programming your 2005 Toyota 4Runner key fob. Ensure you have all your remotes at hand before starting.
- Preparation: With all doors closed, unlock and open the driver’s side door. Make sure all other doors remain closed throughout this process.
- Key Insertion Sequence (Part 1): Within 5 seconds of opening the driver’s door, insert your key into the ignition, and immediately pull it out. Repeat this insert and remove key cycle one more time.
- Door Cycling Sequence: Within 40 seconds of the key sequence, close and then open the driver’s door. Repeat this close and open door cycle once more. Then, insert the key into the ignition and pull it out again.
- Final Door and Key Sequence: Within 40 seconds, close and then open the driver’s door again. Repeat the close and open door cycle one more time. Insert the key into the ignition and leave it in the ignition cylinder. Close the driver’s door.
- Ignition Cycle: Turn the ignition switch 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, the power door locks should automatically cycle (lock then unlock). This indicates that your 2005 Toyota 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 the door locks cycling, perform the following steps on your remote:
- A. Simultaneously press and hold the LOCK and UNLOCK buttons for 1.5 seconds.
- B. Immediately after releasing both buttons, press and hold the LOCK button by itself.
If the programming is successful, the door locks will cycle once. If the locks cycle twice, it indicates the remote was not accepted. In this case, repeat steps A and B for that remote. Repeat step 7 for each additional remote you need to program.
- Exit Programming Mode: Open the driver’s door to exit the programming mode.
- Test: Test all programmed remotes to ensure they are working correctly.
Method 2: Alternate 2005 Toyota 4Runner Key Fob Programming Procedure
If the standard procedure doesn’t work, you can try this alternate method for programming your 2005 Toyota 4Runner key fob. This method is also sometimes recommended for Toyota Avalon models, but for 2005 4Runner, follow the “ALL OTHER VEHICLES” instruction in step 10b.
- Prepare Remotes and Vehicle: Ensure all doors are closed and have all your remotes ready. Open only the driver’s door.
- Key Insertion: Insert the key into the ignition switch, then immediately remove it.
- Door Lock Switch Cycle (Part 1): Press the LOCK and UNLOCK buttons on the vehicle’s door lock switch 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.
- Door Lock Switch Cycle (Part 2): Again, press the LOCK and UNLOCK buttons on the vehicle’s door lock switch alternately at 1-second intervals, repeating this cycle 5 times.
- Key in Ignition: Insert the key into the ignition switch.
- Ignition ON/OFF Cycle: Turn the ignition switch to the ON position, then immediately back to the OFF position. Do not start the engine.
- Remove Key: Remove the key from the ignition switch.
- Programming Mode Confirmation: The door locks should cycle automatically to confirm that the vehicle has entered programming mode.
- Remote Button Sequence:
- b. ALL OTHER VEHICLES (including 2005 Toyota 4Runner): Press and hold both the LOCK and UNLOCK buttons together for 1.5 seconds. Then, immediately press and hold the LOCK button until the door locks cycle.
- Programming Confirmation: The door locks should cycle once to confirm successful programming. If they cycle twice, the programming failed. Repeat step 10b.
- Program Additional Remotes: Repeat the button procedure in step 10b to program any remaining remotes.
- Exit and Test: Close the driver’s door and test all programmed remotes.
By following these steps, you should be able to successfully program your 2005 Toyota 4Runner key fob and regain full remote functionality without needing to visit a dealer. If you encounter issues, double-check each step and ensure you are within the time limits specified.
