Step-by-Step Programming Guide for Your 1999 Lexus ES300 Key Fob
Before you begin, ensure you have your new or existing key fob for your 1999 Lexus ES300 and that your vehicle is in a suitable location to perform these steps. Follow these instructions carefully for successful programming:
-
Start with Key and Door Status: Make sure your key is out of the ignition. Open and unlock only the driver’s side door. Ensure all other doors, including the trunk, are completely closed.
-
Ignition Sequence – Insert and Remove Key: Insert your key into the ignition switch, then immediately pull it back out. Do not turn the key, just insert and remove.
-
Locate Door Lock Switch: Find the power door lock/unlock switch on the driver’s side door panel.
-
Lock and Unlock Cycle (5 Times): Using the door lock switch, cycle the doors from LOCK to UNLOCK and back to LOCK five times in quick succession. Aim for approximately one second per lock/unlock cycle (LOCK and UNLOCK counts as one cycle).
-
Open and Close Driver’s Door: Open the driver’s side door, and then close it again.
-
Lock and Unlock Cycle Again (5 Times): Repeat the lock and unlock cycle using the door lock switch five more times, again aiming for one second per cycle. You need to perform steps 7 through 10 within 50 seconds of this step.
-
Insert Key into Ignition (Again): Insert the key back into the ignition switch.
-
Ignition ON/OFF Twice: Turn the ignition key to the “ON” position (just before starting the engine) and then immediately turn it back to the “OFF” position. Repeat this ON/OFF cycle a second time.
-
Remove Key from Ignition: Take the key out of the ignition.
-
Confirmation – Door Locks Cycle: If you have successfully entered programming mode, the door locks should automatically cycle (lock and unlock once) to confirm. This indicates the system is ready to learn the new key fob.
-
Program First Key Fob: On the first key fob you wish to program, press and release both the LOCK and UNLOCK buttons simultaneously.
-
Hold Lock Button – First Fob: Immediately after releasing both buttons, press and hold down only the LOCK button on the same key fob for about 2 seconds. The door locks should cycle again (lock and unlock) to confirm successful programming of this remote.
-
Program Additional Key Fobs (If Needed): If you have additional key fobs to program, repeat steps 11 and 12 for each additional remote.
-
Exit Programming Mode: Once you have programmed all desired key fobs, simply close the driver’s side door. This action should exit the programming mode.
Troubleshooting Tips
If you encounter issues programming your 1999 Lexus ES300 key fob, consider these troubleshooting tips:
