Avensis No Start - Could It Be The Electronic Lock?

[tony_g100]

Hi, I have an 02 petrol Avensis 85000 miles, new Battery. A few weeks ago it just wouldn't start, no orange engine light on the dashboard. Left it a few days and it started and drove fine. Then it wouldn't start again. Again started fine after just sitting there for three days. Obviously I could check fuel pump, starter motor etc, but before I do I just wonder if this could be something to do with the electronic lock. I don't keep it locked on the drive, but randomly over the last year or two I sometimes come out and it's locked itself - same thing when I stop at the shops and don't bother to lock it - I come back and it's locked. Obviously that could be accidental clicking of an over-sensitive key fob, but it's happened too often, and I wonder if the electronics are not letting me start the car. Anyone experience anything similar, or have any thoughts?

Thanks

Tony
