Locating the override code

You will need a 5 digit code to program the remote into the alarm, if you do not have the code, locate the alarm brain (usually hidden somewhere under the dash) & remove the outer protecting case (if fitted) by unscrewing the four screws in each corner (which some times can be hidden by plastic inserts), once the cover is removed locate the sticker which is usually found on the plastic surround of the smaller of the two large wiring plugs. You will find the five digit code, the model number and a date code printed on the sticker.  If the code is 3 or 6 digits please contact the office.

To check if you have the correct code for programming follow these instructions:

  1. wait for the alarm to immobilise itself – IE the LED flashes slowly
  2. Turn the ignition on the LED will be constantly on,
  3. Turn the ignition off, the LED will now flash, count the flashes for the first number in the override code. For example if the first number is 3, count three flashes of the LED. When the LED has flashed the amount of times that corresponds to the first number of the code turn the ignition switch on.
  4. Turn off the ignition and count the flashes for the next number of the code and so on until all the numbers in the override code have been entered.
  5. If the code has been recognised the LED will flash very quickly for a few seconds, you are now in programming mode and the alarm is also disarmed.
  6. If the LED has not flashed quickly - start again from the beginning.
If the number is ‘0’ count 10 flashes of the LED.
