This step-by-step guide is most likely to help you if your Car Key works fine to start and drive your vehicle but the buttons on your Remote Fob have stopped working. If that’s the case, you may well be able to use the instructions to recreate the “bond” between remote central locking and your car. You should also try replacing the battery.

However, it probably won’t help you if your Car Key no longer starts the Car or if you have a new Car Key. If that’s the case, it’s simply a problem you cannot solve by yourself. All Car Keys made since 1995 need a transponder chip (normally made of clear glass and buried in the plastic part of the key) to be programmed into the vehicle they drive. Then, whenever the ignition is turned, the Engine Control Unit will recognise the Car Key as valid and allow the engine to fire into action. It also won’t help if your Remote Toyota Car Key fob has been physically damaged or smashed, particularly if the internal circuit board is broken.

TOYOTA FOB PROGRAMMING:

TOYOTA

Procedure:
1. The vehicle should be in the following condition-A. The key is NOT inserted
in the ignition, B. The driver’s door IS open, C. The driver’s door is
UNLOCKED.
2. Insert the Key into the ignition switch and then pull it out.
3. Press the Master Door Lock Switch 5 times from Lock to Unlock.
4. Close the Driver’s door then open it.
5. Repeat step #3.
6. Now select the mode by inserting the key into the Ignition Switch and
turning it to the “Run” or “On” position. The programming mode is determined
by the amount of times you go from “key off” to the “key on” position
and back before pulling the key out.
A. 1 time is the “Add” mode. This is used only on some models and it allows
you to add a remote to the already existing remotes. The ECU confirms this by
locking and unlocking the door locks automatically after you remove the key.
B. 2 times is the second mode which will erase all previously programmed remotes
and allow you to program new ones. The ECU confirms this mode by
locking and unlocking the door locks twice after you remove the key
C. 3 times is the third mode which tells you how many remotes are already
programmed to the ECU. It confirms this locking and unlocking the door
locks the amount of times applicable to the remotes coded. If no remotes are
programmed then the ECU locks and unlocks the door locks 5 times. The ECU
will hold up to 4 remotes at any one time.
7. Press the Lock and Unlock buttons on the remote simultaneously for 1.5
sec and then press either button by itself for 1 sec.
8. The ECU will perform the Lock/Unlock automatically to confirm that the
1st remote is stored by the ECU. Repeat step 7 immediately with another
remote and continue until all remotes are registered.
9. Shut the driver’s door and try all remotes.
