Lost your key fob or need to program a new one for your 1999 Toyota 4Runner? No need to rush to a dealership and spend a fortune. You can easily program your 1999 4Runner key fob right at home with a few simple steps. This guide will walk you through the entire process, ensuring you get your remote working in no time.
Follow these straightforward instructions to program your 1999 4Runner key fob:
-
Prepare Your 4Runner: Begin by ensuring your 1999 Toyota 4Runner is ready for programming. The key should be completely OUT of the ignition. Make sure the driver’s side door is OPEN and UNLOCKED. This is crucial for starting the programming sequence.
-
Initiate Programming Mode – Step 1: Take your key and INSERT it into the ignition switch. Do not turn the key, simply insert it and then immediately REMOVE it. This action is the first step to get your 4Runner into programming mode.
-
Enter Programming Mode – Step 2: This step needs to be performed quickly, WITHIN 40 seconds of the previous step.
a. Locate the power lock switch on the driver’s side door. Perform 5 lock/unlock cycles using this switch, always starting with the LOCK action. Maintain a steady pace, aiming for approximately one cycle per second (one cycle consists of one lock and one unlock).
b. After the lock/unlock cycles, CLOSE and then OPEN the driver’s door. -
Enter Programming Mode – Step 3: Again, this step must be completed WITHIN 40 seconds.
a. Repeat the power door lock switch operation: perform 5 lock/unlock cycles, starting with LOCK and maintaining a pace of about one cycle per second.
b. INSERT the key back into the Ignition.
c. Now, you need to use the ignition switch to select the programming mode.- Turn the ignition to the ON position (Do NOT start the engine) and then back to the OFF position.
- Perform this ignition ON-OFF cycle ONCE if you want to retain any previously programmed remotes and add a new one.
- Perform this ignition ON-OFF cycle TWICE if you want to ERASE all existing remotes and program only the new remote(s).
- Perform this ignition ON-OFF cycle THREE times to CHECK how many remotes are currently programmed to your vehicle.
- Perform this ignition ON-OFF cycle FIVE times if you want to ERASE ALL existing remotes programmed to the vehicle.
d. REMOVE the key from the ignition.
-
Enter Programming Mode – Step 4: Within a very short window of 3 seconds after removing the key, listen and watch for confirmation. The Power Door Locks should automatically cycle LOCK and then UNLOCK. This lock/unlock cycle is your signal that your 1999 4Runner has successfully entered the key fob programming mode.
-
Program Your Remote: Now you are ready to program your key fob, and you have 40 seconds to complete this step.
a. Take the remote you wish to program. PRESS and HOLD both the LOCK and UNLOCK buttons on the remote simultaneously for 1 second.
b. After releasing both buttons, immediately PRESS and HOLD ONLY the LOCK button for 2 seconds. If the programming is successful, the Door Locks will cycle LOCK and UNLOCK once more to confirm that the remote has been successfully programmed. -
Program Additional Remotes: If you have more than one remote to program, you can program additional remotes at this time. Simply REPEAT Steps 6a and 6b for each additional remote you need to program.
-
Exit Programming Mode: To exit the programming mode, simply CLOSE the Driver’s Door. This action will signal the system to finalize the programming process.
-
Test Your Remotes: Finally, it’s time to TEST all the remotes you have programmed, including the new one and any previously working remotes. Ensure that the lock and unlock buttons are functioning correctly. If all remotes are working as expected, then the programming is complete.
By following these steps, you can easily program your 1999 4Runner key fob and regain the convenience of remote locking and unlocking. Enjoy the ease of having your key fob working again!
