On Board Programming

Home > Services > Automotive > On Board Programming

On some vehicles with transponder chips there are on board programming procedures available. A on board programming procedure is a serious of actions with the vehicle that put it into learn mode to accept the addition of another key. Note most of the time you need a current working key. The most common manufacturers with on board programming are GM, Ford, Chrysler, Mazda, Toyota and Lexus.

Here are a list of vehicle models and their programming procedures:

1998 Mazda 626

The on-board programming procedures for the Mazda 626 should be used only if the preferred
methods are unavailable. The Mazda dealers use a New Generation Star Tester to originate and
add new duplicate keys to this model vehicle.
The ILCO RW2 or RW2, RW3, RW4/EZ-Clone should be used for these purposes by Ilco dealers.
The following procedures will require pre-programmed keys. Ilco transponder keys fo
Mazda are not available pre-programmed

 

Originate New Master Key or Add Duplicate Key

LOCK position. Repeat until this has been done five times. Do not let the lock sit for more
than one second in any position during this step.

flashing rapidly. Within twenty seconds turn to the LOCK position and leave it there for five
minutes. After this five minute delay, the security light should slow to a much slower rate.
3. Within twenty seconds, enter the code password.
4. The code password is obtained by supplying the vehicle’s Immobilizer Unit serial number to
Mazda. It is an eight digit number unique to each Immobilizer Unit.
5. While carefully watching the dash mounted security light, turn the ignition to the ON (RUN)
position. Count the number of flashes by the security light and turn back to LOCK when the
number of flashes equals the first digit of the password.
6. Within thirty seconds, turn the ignition lock back to ON (RUN) and count until the number of
flashes matches the value of the second digit of the password. Turn the ignition lock back
to LOCK.
7. Repeat until all eight password digits have been entered. Use caution and turn the lock
from one position to the other only when the security light is NOT illuminated. If a mistake
is made or the count of flashes is lost, wait forty-five seconds and start over.
8. When the security light stops flashing and stays illuminated, the password has been entered
correctly.
9. Start the vehicle and the security light should go off within two seconds.
10. Additional new keys may be added by inserting them and starting the car within twenty
seconds of removing the previous key.
11. Thirty seconds after the last key has been removed, the vehicle will end the program mode
and return to normal operating mode.
