C3 locking...again...

[alex666_slo]

Hello guys,

I found a lot written about C3 locking problems and mine 2006 also have issues with key fob.. With key it works like a charm. Not to lose to much time I just bought aftermarket remote loking system that shoud do the work by connecting it to pins 13 and 15 on PH2 connector.. but as locking/unlocking with key works I thought I would connect that same way as door key command is..

but... there is always a but... When I checked the wiring I noticed that there is only one pole swich for locking/unlocking and that makes me thinking.. how does it know wheater it needs to lock or unlock when signal is always pulled to GND?

I will do some measurmenst in upcoming days but if anybody worked with that I am open for suggestions.


As alternative I could just buy new keyfobs but I lost security card and If my info is right, I can't add them without it ass original also have immobilizer on PCB ... Correct?

thanks in advance Alex

Your dealer can provide the codes for a nominal charge, with proof of ownership / ID / Address etc.

They are solenoids and the polarity is reversed from locked to unlocked. The power and ground ends are swapped from mode to mode.
