Lexus IS200 Reprogramming Key Fob
Lexus IS200 Reprogramming Key Fob
Asi hopefully mines a master as i only got one 3 button key with it.
what happens if it is not the master and other way around it?
Big problems ! In theory you need a new ECU, and that's what Lexus will tell you
hock:But I think it's possible to find an auto locksmith who will somehow manage to program you a new key, but you'll have to phone around.

Just to add something on this, I have a master key but it's come out of it's plastic cover so I don't use it, anyway I went to run the car the other morning with it to clear the ice and left the missus with the non broken key, the master opened the doors fine but the car wouldn't start with it so it must need re-programming, had a similar problem when I first got the car, anyway my point is if you have a spare key but never use it still start the car with it on a regular basis so the car doesn't forget the key. Lexus told me the key has nothing to do with the imobiliser but from my experience it does.

Good point, when I got my car it seemed to have "forgotten" two out of the three keys.
Also Lexus are talking rubbish there as you say, there's circuitry in the key fob and by the key lock which work the immobiliser, you can see this from the flashing "Security" light going out.

(for a total cost of £40, that was both blank blades (a 2 button and a 3 button, getting them cut, and both transponders)Key Programming (so the key starts the car)
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. To end programming step on the 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 be come on and start 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 (so the buttons operate the locks)
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) YOU WILL NOTICE THE SECURITY LED FLASHES QUICKLY NOW
4. Close and open drivers door.
5. Using the electric lock switch. Lock and unlock 5 times again.(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, unlock) by themselves then the car isn't in programming mode and you must start over.
8. On the new remote. Press and hold Lock and Unlock button at the same time for no more than 2 seconds.
9. On the new 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. Don't start over just yet:
As long as the car is still in programming mode you can keep trying step 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.
(I did have to repeat steps 8 & 9 a couple of times leading me to believe this guide is very slightly inaccurate with regards the new fob presses, but third time lucky)
After you get the remote to program then continue on with step 10.
10) Close and open door to end programming procedure.
ENJOY
Having tried to program my 2 new keys without success, I googled, specifically IS300 key programming and found it varied very slightly from the guides already here, I shall post them as using the following guides instead, I successfully managed to do my keys (for a total cost of £40, that was both blank blades (a 2 button and a 3 button, getting them cut, and both transponders)

i think it will cost a fare bit to sort out a new master key
