Hopefully nothing serious. Two starters would be frozen internals in the locks not allowing something to set properly or as I experienced with one about the age of yours last year was the bonnet switch not seating properly. It's up at the rear right, i.e. under the corner of the bonnet at the bit closest to the steering wheel. Basically its mounted on plastic and 'gives' with age. A short term fix is to tape a washer or 1p coin to the underside of the bonnet where it touches the button. This pushes it down an extra millimetre or so. Give that a try.
