How to Reprogram a Lexus Key Fob

Updated April 17, 2017

If you have recently purchased a spare remote or just replaced the battery in your backup Lexus key fob, you probably need to reprogram the remote to work with your car. You can take the new or malfunctioning key to a Lexus dealer and have the key reset in no time for a charge ranging from £32 to £48. With just a little time and patience, however, you can do the reprogramming yourself and save some money.

  1. Close and lock all the doors of your Lexus, then unlock and open only the driver's door.

  2. Leave the driver's door open and insert the key into the ignition, but do not turn it. Remove the key from the ignition.

  3. With the driver's door open, lock and unlock the doors five times with the electric lock switch in the car. Take care to complete five lock/unlock cycles, ending on unlock.

  4. Close and open the driver's door.

  5. Repeat the lock/unlock cycle performed in Step 3.

  6. Insert the key into the ignition, and turn the car on. Turn the car off, and remove the key.

  7. If the locks did not cycle, start over from the beginning. If the locks do cycle on their own, meaning they lock and unlock at each door, press the "Lock" and "Unlock" buttons on the remote simultaneously for no more than two seconds.

  8. Press and hold the "Lock" button for one second. The locks should cycle once, which means your Lexus has accepted the new remote. If the locks cycle twice, the reprogram was not successful; start over from the beginning.

  9. Close and open the driver's door to complete the reprogram on the remote.

  10. Tip

    If your first attempt fails, try performing steps 7 and 8 from outside of the car, which may help improve the signal strength between the remote and the car.
