2. [Select]
3. [46 – Cent. Conv.] or [35 – Cent. Locking] (whichever is applicable to the car)
4. [Adaptation – 10]
5. Enter channel “01” (May be channel “21” in some Audi models). [Read]
6. This will display the number of currently stored remotes in “Stored Value”.
7. Enter your total number of keys up to a maximum of 4(including any existing keys) in “New Value” [Test]
8. Verify that the number in “Test Value” is correct. [Save]
9. Then press and hold (for at least one second) the UNLOCK button on the fob, at which time it will be learned. If you’re programming more than one fob press and hold the UNLOCK button on the second fob for one second, press and hold the UNLOCK button on the third fob for one second, etc. You have a total of 15 seconds to do them all.

47. What if the procedure above does not work (neither Channel 01 nor Channel 21 are available)?

If the above procedure does not work (neither Channel 01 nor Channel 21 are available), follow this procedure:

1. Insert a working (old) key in the ignition and turn to the ON position (do not start car).
2. [Select]
3. [46 – Cent. Conv.] or [35 – Cent. Locking] (whichever is applicable to the car)
4. [Meas. Blocks – 08]
5. Enter group “003” (may be group “007” in some vehicles)
6. [Go!]

The value in field 2 shows how many remotes have been matched and in which memory positions (for example, “0001” indicates 1 transmitter in position 1).

1. Lock the car from outside using the new, unmatched key in the driver-side door lock. You may need to hold the key in the unlock position while you do the next step.
2. Press the UNLOCK button on the new key within 5 seconds often enough to reach next memory position (so, if the value in field 2 was 0001, you should press the new key’s unlock button twice, to put the new key in memory position 2)..
3. Wait 5 seconds and press the unlock button on the new key to unlock the door.
4. Turn the ignition key to OFF and remove the old key.
5. Press LOCK and UNLOCK with the new key.
6. Insert the new key in the ignition and turn to the ON position (do not start car).
7. [Select]
8. [46 – Cent. Conv.] or [35 – Cent. Locking] (whichever is applicable to the car)
9. [Meas. Blocks – 08]
10. Enter group “003”
11. [Go!]

The value in field 2 should now indicate 0011 in the example used, showing the old key still matched in position 1 and the new key matched in position 2.

48. Is it necessary to clear out existing matched remotes?

In some cases, it may be necessary to clear out existing matched remotes using the following procedure:

1. [Select]
2. [46 – Cent. Conv.] or [35 – Cent. Locking] (whichever is applicable to the car)
3. [Adaptation – 10]
4. Enter channel “00”
5. [Read] [Save]

When the prompt asks if you are sure you want to save a value of 0 to Channel 00, click [Yes]

After doing so, no remotes will be matched. You’ll need to follow the appropriate above procedure to match all of the remotes.

49. What kind of acknowledgement the car give you as each key is learned?

The car may give you some sort of acknowledgement as each key is learned (lights flash, horn beep, etc.)
