Hi. I bought my A4 without the key fob for the alarm. It has a cobra alarm installed and i have the card with the code. I purchased a replacement fob from ebay and either the fob is the wrong one, the code is wrong or i am not using the correct procedure to put the code in. I got the instructions on how to do this from the cobra web site and i think i am doing it correctly. What i am asking is where do i go from here. Should i just get a whole new alarm system when there is a chance the alarm that is in it is perfectly fine or is there anything else i can try. Would getting one of these be of any use for the alarm? http://www.rclick.co.uk/product_info.php?cPath=50&products_id=269 Any help would be great.
