Leegee87 Posted March 25, 2014 Share Posted March 25, 2014 Hi I have had my bonnet mechanism replaced and my sub and amp wired up by a mechanic friend of mine on my 2006 Focus ST-3 . Since then I have had some issues with the alarm, it seems to be when people use their key fob to unlock when in close proximity to mine it sets my alarm off. Note: this only seems to happen if their vehicle is a Ford. I have been searching for various solutions to the problem for a little while now to no avail. I don't know whether it is something to do with the battery being left disconnected whilst the sound system was wired up? I would really appreciate any help or suggestions as this is driving me insane, as you could imagine! Thanks (First post!) Lee Quote Link to comment Share on other sites More sharing options...
Preee Posted March 25, 2014 Share Posted March 25, 2014 First place to start is the bonnet, it may be the root cause seeing as your have changed someting on it. Other cause could be voltage leakage through the new amp. Does it completely power down when car is off? Check your bonnot sensor , should be two wires. Check your earth points on amp for voltage draining. I can't see how the other remotes are triggering but i guess it could happen , not sure if the systems have a detection if the signals are being scanned.

Leegee87 Posted March 25, 2014 Author Share Posted March 25, 2014 I thought it was the bonnet sensor at first so I bridged the connection and it has not resolved the issue. The amp does switch off completely when the car is off. I will check the earth points and report back. I agree, it does seem strange how other peoples key fobs set my alarm off, it's most frustrating as the other car in the family is a Ford!

Leegee87 Posted March 26, 2014 Author Share Posted March 26, 2014 I've disconnected the amp completely and the problem still persists It definitely seems to be other peoples keys that set it off. It's as though a Ford remote frequency it does not recognise causes the alarm to sound. Thanks Lee Quote Link to comment Share on other sites More sharing options...
Preee Posted March 26, 2014 Share Posted March 26, 2014 Perhaps , program reset all the keys to the car , it might block out all the other frequencies then. Quote Link to comment Share on other sites More sharing options...
Leegee87 Posted March 26, 2014 Author Share Posted March 26, 2014 I've reprogrammed both keys to the car and it still goes off. Could then new wiring have any effect on it? Thank you Lee Quote Link to comment Share on other sites More sharing options...

Preee Posted March 26, 2014 Share Posted March 26, 2014 Well i guess the wiring could have an effect on it , are you certain it only goes off when someone else locks their Ford Car. Only way to check the wiring is discoect it all and see if the alarm still goes off. Quote Link to comment Share on other sites More sharing options...
mick85 Posted March 26, 2014 Share Posted March 26, 2014 There is a radio frequency receiver in roof could be an issue have checked faults won't show light on dash Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
Leegee87 Posted March 26, 2014 Author Share Posted March 26, 2014 Yeah I'm pretty sure it is only Ford's that set it off. I've never noticed it going off with any other vehicles apart from Ford's. It seems as though something needs calibrating with regards the frequency so maybe that could be it. Where abouts is the receiver?
