About going into detail, understandable! Thanks for the reply Scotts90

Turns out I have a Scorpion SA30 system installed. Should I have a fob other than the standard 2 button land rover one? Can I just unplug it? Any help appreciated.

Hi Folks,Problem with the immobiliser on my Defender TD5 99'.Fitted new front LED spotlights yesterday. Disconnected battery using correct procedure. Disconnected old lights and wired in new lights. Reconnected battery before bolting new lights into place to check all was ok. Lights all working - no problems.Disconnected battery again using correct procedure and finished bolting lights into place. Checked connections one last time and all secure. Reconnected battery again.This time small blue light started flashing on top of the dash panel and when trying to start siren goes off and engine immobilised. Removed negative terminal and siren stops. When I reconnect the negative terminal there is no alarm only when I try to start engine.I've tried searching on the internet and these forums but it's a bit of mine field. Can any one explain to me what exactly is going on?Thanks in advance.Sam
