As per above... Went to unlock and open the other day and nothing! Does anyone have any ideas? As always, any advice is most appreciated!

I had the problem on left front door - it was under warranty and they replaced the whole unit.

Then I had it on the left rear door, no warranty anymore. Left it alone and it started to work again after a few days, then a bit unstable for a couple of weeks and now been working for months without any problems. Didn't think about it anymore until I saw your post.

Try this - Lock the car, then pool and hold the lever while you press open on the key fob. This should unlock the door.
