crimsonfly Posted September 1, 2015 Posted September 1, 2015 Ok, so we have a Citroen C8 (petrol, 2006). Its been a pretty good family car for the 6 of us and we've just got back from 3 weeks in Europe. Today though we could not get into the car: not by the remote (it doesn't function anyway); nor by either of the door locks. The doors feel 'dead-locked' and the key hits a wall of immovability when you try to turn it on either door. When the car was last locked (having been left unlocked for a few days) the wing mirrors stayed out - they normally retract electronically. I have replaced the key fob battery but to no avail. I'm guessing its either the car battery or a problem with the lock; but I thought a manual unlock did not require a charged battery and if its a lock problem, why both doors?How will we ever get back into our car?

paul.h Posted September 2, 2015 Posted September 2, 2015 Welcome to the forum. Did the key work in the locks before this problem ? If not then possibly you have the wrong key or if the locks are seized, something like wd40 sprayed in the locks and then the key used/turned backwards and forwards in the lock may gradually free it and unlock the doors. Once you have access in the car the remote will need to be initialised due to the new battery and the procedure for this will be in the handbook but will be something like put the key in the ignition and immediately press the lock button. When the mirrors did not fold, if the engine had not been run just before, was the car in eco mode when the doors were locked since this may have stopped them folding ? Quote
crimsonfly Posted September 2, 2015 Author Posted September 2, 2015 Thanks for the reply. I'll give the WD40 a try this morning and let you know. Fingers crossed! Quote
Simple Posted September 3, 2015 Posted September 3, 2015 (edited) This is a very weird problem, if you are not using the wrong key, and if the key is not damaged (or has some deposits on it), and if the locks have not seized (due to dirt or frost), then someone must have tried to pick the locks and damaged them or threw some dirt into them!!! Clean the key with a toothbrush or something similar, spray some DW40 or diesel (even better for this purpose), then try (both sides) carefully opening the locks.
