keener Posted December 3, 2009 Share Posted December 3, 2009 I have a Cobra alarm/imobiliser which is only a couple of years old. Today I locked the car with the key-fob but when I came to unlock it I pressed the button - nothing. Tried several times but no joy - thought I'd unlock with the key and neutralise the alarm with the little press thing and the contacts inside the car but no alarm sounded. Basically the imobiliser has kicked in and car wont start. Also, randomly, the clock has stopped and there's no 'bonging' noise when door is open and keys are in ignition. Also the little red led that flashes when the imobiliser is on is not lighting up at all. I called out Mr AA but he couldn't fix it despite trying all the resets he could find in his system. The car therefore got recovered to my house but is imobilised. I need any expert advice I can get! I'm based between Banbury and Oxford in Oxfordshire - can anyone recommend an alarm specialist who can help? A mobile one would be best as the car isn't going anywhere without help! I contacted the people who installed the alarm in Newcastle (when Jurgen imported it for me) who suggested that I need the 4 digit PIN code but I can't find it anywhere. I'm not even sure I had one but I have moved house since it was fitted and that's always a nightmare. I'm hoping I can either get the code from Cobra or bypass it somehow but feel free to put me right and point me in the direction of a good expert for help! Thanks in advance!

Meko Posted December 3, 2009 Share Posted December 3, 2009 Not a specialist at all, but my mate had a similar problem when he tried to programme a new fob. Imobiliser locked on, within about half an hour we had it disabled and the car started. We just pulled the dash apart, found the box and followed the cables back to the ignition where we disconnected them and re-wired the originals. Although!! it was a lot easier than we thought so there's a good chance it was a self install and not done properly which left it easy for us to do.

Matt Harwood Posted December 3, 2009 Share Posted December 3, 2009 I'm 99.999999999999999999999999999% sure this has nothing to do with the alarm.... At a guess, it sounds like the car battery is flat. The amount of people, including the bloody AA and RAC that blame immobiliers for flat batteries an dodgy starter motors is quite amazing The immobiliser, immobilises the engine, not the clock, and certainly not the bonging noise. The fact that the alarms LED isn't on, the remote didn't work, and the alarm didn't sound, screams a lack of power. Check the battery first. I'm fairly sure this is going to be the problem. Check the battery connections are good as well. Link to comment Share on other sites More sharing options...
keener Posted December 4, 2009 Author Share Posted December 4, 2009 Mr AA did check the battery as the first step. It's barely a year old and is fine so we moved on from there. He also checked that the key fob was emitting a strong signal which it was so not a battery issue there either. Basically when the key is turned it just goes click which is what it does when the imobilisers kicked in so that leads me to think it's deffo the root of the problem I was confused by the clock and 'bonging' and I thought it could be a fuse that powered all of them but I don't think that was the issue. However, my limited knowledge (especially poor in electrics) means I really need an expert to check the installation so I'm searching Yellow Pages now.

snake Posted December 4, 2009 Share Posted December 4, 2009 do the lights work? Link to comment Share on other sites More sharing options...
keener Posted December 4, 2009 Author Share Posted December 4, 2009 Yup, lights, radio, lights on dash all work! Link to comment Share on other sites More sharing options...
Matt Harwood Posted December 4, 2009 Share Posted December 4, 2009 I've been an auto electrician for 15 years + and specialised in car security. I've seen soooooooooooo many cases when the AA or RAC man says the battery is fine. Just turning on the lights isn't a good way to check the battery is OK. Obviously, I'm not there, so I can't say for absolute certain, but I would be truly gobsmacked if it is the alarm. Try charging the battery anyway, or carefully jump-starting it.

keener Posted December 10, 2009 Author Share Posted December 10, 2009 OK, so I took out the battery (new in Oct 08), fully charged it, replaced it and .... nothing. Still same problems, no 'bonging', immobiliser led not lit up, radio etc works, just a click when key is turned. Any ideas? Link to comment Share on other sites More sharing options...

keener Posted December 11, 2009 Author Share Posted December 11, 2009 (edited) It was a fuse. The one that does the interior light as well I think he said. Anyway, replaced it and the 'bonging' I missed so much started instantly - problem solved. The chap from JFK Automotive got it within 2 mins! I guess that's what expert knowledge from installing the systems gets you! BTW JFK were great. Good service and v quick to come out to me. http://www.jfkautomotive.co.uk/index.htm Thanks for everyones advice given above as well.
