Hi guys. I am attempting to alter my PIN code on my alarm… According to the instructions the LED on the keypad lights once to confirm pressing the button – this is the case. However, a flashing led means that you have to start the sequence again. My LED flashes when I have entered the fourth digit of the existing PIN number (which I have found with the vehicles’ documentation). This means that I have to start from scratch and am not able to enter my new PIN. Does it suggest that the PIN I am entering is the incorrect one to the one I have ‘found’ (has the previous owner changed it?), or am I doing something stupid??
