vehicle key to the alarm ::

Occassionally, and for no reason, the alarm fob may stop activating/de-activating the alarm. Obviously you may have a flat battery but this will be clear after the first point below...no flashing light means replace the battery! You may also have a faulty keyfob swithc or other internal key problem. the good news is this can be fixed, contact me for details of the people who can help for a small charge. If you key appears to work, try the instructions below before sending it off for repair...but you must have the four digit key code.

1.
|
Press
the button on the Rx for approx 2 secs. The LED should flash for
the whole time you hold the button. |
|---|---|
|
2.
|
Release
the button. After approx 2 secs the LED should flash once. This
is a request for the first digit. |
|
3.
|
Press
the button the number of times corresponding to the first digit, ie
if the first digit is 4, then give 4 presses. Every press should cause a brief flash. |
|
4.
|
Approx
2 secs from the last press, the LED should flash again to request
the second digit. |
|
5.
|
Continue
in the same way for the other 3 digits. If a digit is 0 then
don't press at all, just wait for another request flash. |
|
6.
|
Having
entered all 4 digits, the LED will either stay oncontinuously
meaning that either there has been an error entering the code, or the code is incorrect. Or the LED will flash, meaning that the code is good. |
|
7.
|
At
this point if the LED is flashing, hold the rx button down and press
the tx button.The rx LED should light continuously if the code has been memorised. |
|
8.
|
There
is a country setting procedure that follows but I'll omit this as it
defaults to EEC so don't do anything.
|
|
9.
|
The
rx LEd should now flash 6 times to show all is OK. If you get 18
flashes start again from point 1. |
|

|
Repeat
for key 2.

If
you do not have the correct code, check what the National Security Agency
have on record, (that the sticker you should have on the windows, or a dealer can check for you), as they are given all the key and immobiliser codes at the time of importation. |

If
none of the above works at all, then you are looking at a new roof receiver.
