Help! Ecu Remote Reprogramming

[RichardMD]

Help!

I had the problem a month ago whereby my remotes stopped working and my Is200 didnt recognise them. I found some posts with reprogramming instructions. I got this to work.

However, its happened again and i cant get it reprogrammed.

Now, step 3 worked and locked/unlocked once. Step 4 doesnt work and locks/unlocks twice which suggests its failed. I have tried for an hour now!

There are discrepancies with some posts.....are the instructions below ok? Some say turn on the ignition in step 1, some say put the key in and dont turn!

I used the following:

The procedure is as follows:

1). With driver's door open put programmed key into ignition, do not turn, then remove it.

2). Within 40 seconds:

Press LOCK and then UNLOCK on driver's door switch 5 times at 1 second intervals.

Close and open driver's door.

3). Within 40 seconds:

Press LOCK and then UNLOCK on driver's door switch 5 times at 1 second intervals.

Insert key into ignition and switch ON and OFF:

once to keep original remotes,

twice to erase original remotes.

Remove key from ignition.

System will now lock and unlock:

once if originals kept,

twice if originals erased.

4). Within 40 seconds:

Press LOCK and UNLOCK buttons on remote simultaneously for 1.5 seconds.

Within 3 seconds press any button on remote for 1 second.

Locks should then lock and unlock once.

If locks lock and unlock twice restart procedure.

5). Within 40 seconds:

Repeat step 4 for additional remotes up to a maximum of 4.

To exit programming insert key into ignition or close driver's door.

Thanks!

mmmm.....took my time! varied it fast and slow......and applied the same technique to the reporgramming issue :D

Got there in the end! Its worrying that it will keep doing this....is there any permanent cure...?
