Vauxhall Zafira B - Double Lock (Deadlock) - HCB_GB

Can anyone help me with my 2009 Vauxhall Zafira B 1.6 Design. My central locking double lock (deadlock) stopped working. It happens before but after fiddling with the key fob while it still in the ignition I manage to make it work again, but I forgot how I manage to do it and the sequence. I have a habit of opening the door first before pulling the key out off the ignition switch, I think that is the reason why my double lock(deadlock) system stopped working again. can anyone knows how to reset it to activate the double lock system again. Thank you

The deadlock system will only work if the electronics can "see" that all parameters are met.All doors ,boot and bonnet shut,and key out of ignition switch.The latter is where your problem could be,key detection switch at the base of the ignition barrel.There is no system to reset.It either works or doesn't.Also does your radio switch off when the key is pulled from ignition.?

Yes radio goes off few seconds after pulling the key from ignition. Worst things happend today. After driving my car, all my door wont open from inside and i was stuck, i mange to open the windows using my key fob and I managed to open the drivers door manually with key reaching out from the window. For some reason the drivers door started working again fully inside and out but all 3 passenger doors are locked and cant open it from in or out how strange that all 3 doors mechanism will stop working all in the same time and the left rear window wont open as well. But when you lock/unlock the door using the fob you can hear all doors clinch. Are this all issues regarding the wirings? I read some post in the net regarding vauxhall rear door wiring do snaps, but if that is the case is it possible that all 3 doors wiring snaps all at the same time? it is strange indeed. Or it is possible that the driver door wiring is the culprit as this wire controlls all the doors windows possibly lock as well. Just asking... Thank you

Wiring problems to the rear doors could be a possible fault.(not uncommon).It only needs one door to have broken/shorted wiring to cause locking faults to all doors.You need to carefully pull back the rubber boots that run from the pillar to the doors to inspect the wires.
