Hello, I have a 2003 Corsa that’s started locking/unlocking itself. No idea how long it’s been happening, a neighbour alerted us today and I’ve now seen it for myself. The remote key is broken, so we have to use the actual key hole (is that the correct term?) on the car itself to lock/unlock. The car probably needs resealing as a lot of condensation is on the inside of the car of late, with the bad weather and all. The battery was replaced not too long ago (3/4 months?) Can anyone suggest why this is happening, or a solution? (That hopefully won’t break the bank!) Thanks in advance, Jason
