Could some explain - what is the sequence to programming a key, for 1995 SC 400. I just bought this car and the key works everything, except the auto buttom lock. I have replaced the battery, but It did not help.

Thanks, mark.blend

Open driver door, keep it open and in the unlocked position

Put original key in ignition and pull out

Lock and Unlock the doors 5 times

Close the door and open the door

Lock and Unlock the doors another 5 times

Put the Master Key in the ignition, turn it on and then off and remove from the ignition

You should hear a confirmation beep within 10 seconds and the door locks should actuate

Push the button on the new key

Close the door and open the door

Push the button again on the new key

good luck
