A few times lately I have been sitting in my 52 reg Mondeo with the key fob in the ignition and the electronic door locks have locked themselves. This has happened several times and seems mostly when I am near B/Ham Airport but this may not be relevant.
This morning I unlocked the car with the zapper then stood outside with my hands nowhere near the buttons and every couple of minutes it would lock itself. I did this repeatedly. Is it something to do with the battery of the key fob or do I have another problem?
