Hi Hi all i got a Valeo key of ebay can do noting with it just a we question if i get a 3botton key out of a smashed is200 can i reprogram it to work on my is200
I would say most probably...YES!!! but don't get the keys quoting canada codes. These have panic written on the "Lock"button. As yet no sequence I am aware of has been succesful on the European Lexus.
I am still trying to find out if the newer is200 (02-06) uses a different transponder than the older versions. (99-02)
As it appears that all the people having trouble coding the cars have newer cars.
Also...When i took my key to be cut the key cutter said he could program my transponder for me. When he tried the machine said the transponder was in-compatible with my key. It too is a Valeo key and I have an 52 car.
Working on confirmation for this but maybe following the above guides and variations you may get somewhere with the Valeo.
Good luck.
Ok so my findings after posting this earlier are...
1.The Valeo key that I possess will not or cannot be coded to my car.
I used this method as all others did nothing in my car...
Key Programming (Starter Chip)
1. Insert an already programmed master key into the ignition. Do not turn.
2. Press and release the gas pedal 5 times.
3. Press and release the brake pedal 6 times.
4. Remove the key from the ignition.
5. Insert the new key you want to program into the ignition.
6. Press and release the gas pedal one time.
7. Wait 1 minute. The security light will be blinking for this one minute. When it stops blinking your key is programmed (Be patient, it'll happen). To end programming step on brake one time.
NOTE: Look for your security light. This light will guide you during the programming procedure. The security light will go off at Step 1. It will remain off until Step 6. The security light will come on and start to blink after Step 6 until the key is programmed. If the security light comes on after Step 4 STOP the procedure and start over again.
If you perform this procedure too slowly your car will not go into programming mode. If you can not get your car to go into programming mode make sure you are using a master key and not a valet key. If you have a master key then you will probably need to perform this procedure more quickly.
Remote Programming
1. Close and lock all doors. Unlock and open drivers door.
2. Put key into ignition and remove. Do not turn it on.
3. Using the electric lock switch. Lock and unlock 5 times. (Lock, Unlock, Lock, Unlock, Lock, Unlock, Lock, Unlock, Lock, Unlock)
4. Close and open drivers door.
5. Using the electric lock switch. Lock and unlock 5 times. (Lock, Unlock, Lock, Unlock, Lock, Unlock, Lock, Unlock, Lock, Unlock)
6. Put key into ignition. Turn to "ON" , turn off and remove.
7. You will see the door locks cycle by themselves.
If the door locks do not cycle (lock and unlock) by themselves then the car isn’t in programming mode and you must start over.
8. On the remote, press and hold the LOCK and the UNLOCK button at the same time for no more than 2 seconds.
9. On the remote, press the LOCK button for no more than 1 second.
AT THIS POINT, the locks should cycle by themselves ONE time. This means the procedure was accepted.
IF the locks cycle twice it has failed.
The most common reason for programming failure is because the car didn’t receive a good signal from the remote. To fix this problem try these tips. 1) Stand outside of the car while you are performing steps 8 and 9. 2) Don’t hold the remote buttons down as long.
As long as the car is still in programming mode you can keep trying steps 8 and 9 until you complete the programming. If you wait too long and the car exits the programming mode then you must start over.
After you get the remote to program then continue on with step 10.
10. Close and open door to end programming procedure.
My valeo key would not code the doors nor ignition but.
2. I managed to code an old spare key with 2 buttons that I had from my celica. I managed to code it to start my car,
Still not tracked down a method to get my doors to unlock though.
So I know I am doing the sequences correctly but still no joy in a successful door and car starting key.
AN edit instead of bumping the thread back up.
I have had lots of trouble getting my head around the immobiliser problem until I blundered into this...
Turns out that there are "Two" different transponders. 4c and 4d.
If you look on the back of a new blank key from ebay member ejaz078 or similar it says..."CLBT/C/245/2002" on it. The "C" being the transponder chip id.
It also says on the back of said key that its a DENSO 1512v. This is in-fact A LIE!!! What it actually is, is a VALEO.
The "Valeo" Unit was suppied to the newer model cars. 2003 up I think. And the transponder chip fitted in this unit is a 4"D" chip. Totally uncompatible with our models. Mine being an 02 registered in 03
We really do need the DENSO unit as this is the one with the "4c" chip.
So if you get a key from ebay make sure you ask the seller to confirm that inside his case is a DENSO unit and NOT a VALEO.
I managed to get this info because I was curious to how I managed to code my Gen 7 Celica key to the system and not the Valeo. Turns out the Celica also uses the "4C" chip.
I have now swapped the transponder (a little rectangle with a corner cut off black lump about 8mm long and 4mm wide) out of my 2 button fob and put it in my 3 button fob. Just got to try to work the doors remotely with it now. Hmmm!
