My locks are still knackered. Vauxhall charged me 80 sheets to tell me that the problem is either a motor or the main brain. (20 fault codes found). I am gonna change the brain and hope for the best - I think it is the brain at fault because when the car is unlocked, the petrol lock sometimes needs forcing and the pin thingy needs a push. Its as if the brin isn't sending enough power or somet - anyway.....ANYONE know how to change the brain (in the driver's footwell I think). Do I need to disconnect the battery or can I just unplug etc. Also, will my current key work with the new brain?
