This is for 155's so use at your own peril
New receiver proc:
1. Press the button on the receiver- does the LED flash? (the power for the courtesy light is seperate from the receiver power so this also shows that the receiver is powered correctly).
2.If the LED does flash, keep the button pressed down and then press the button on the key fob.
If the receiver LED lights continuously, the key code should have been memorised, so release the receiver button. The receiver LED should then flash 6 times to show that the procedure was carried out correctly. If there is a problem the receiver LED will flash 18 times.
3.Do this for all your keys.
If the above doesn't work (ie you get those 18 flashes) try:
1. Get your 4 digit key codes, there should be one per key.
2. Press the receiver button for approx 2 secs, the receiver LED should flash for the whole time that the button is pressed.
3. Release the button. After approx 2 secs, the receiver LED will begin to flash, this is the prompt to enter the first digit.
4. Press the receiver button the number of times corresponding to the first digit of the key code (eg the code is 4321, press the button 4 times). If there is a zero in the code, don't press the button at all for that digit, just wait for the the next prompt. Each time the button is pressed, the receiver LED should flash.
5. Approx 2 secs after the last push of the button, the receiver LED will flash to prompt for the second digit.
6. Carry on as above until all 4 digits are entered.
7. When all 4 digits have been entered, the receiver LED may do one of the following:
a. Stays on continuously. This means that the code was not found in the receiver memory. Try again, if it still doesn't work, then it looks like a new receiver is on the cards.
b. Flashes. Code has been recognised and the memory has been unlocked. You can now reprogram the receiver using the procedure used for a new receiver (ie the first procedure in this post).
Hope this helps
