Mike....whooooooooooah
I hear you, I just fell asleep on my nice new sofas this evening and forgot to log on. Right, don't panic I can offer a probable solution - but of course if you had used the 'search' facility you would have a probable answer

I have been here and done it - so to speak....
Here's a couple of questions you need to consider:
1. does the remote operate more satisfactorily at night?
2. during the day, if you surround the remote receiver with cupped hands such that the sunlight doesn't hit the IR receiver, will the remote operate now?
3. does the red or green light flash more times than it should and with irregular counts?
In summary (as both these threads conclude) if your remote operates better at night or/and with you blocking the sunlight entering the IR receiver you need to change the RED/GREEN IR receiver and key barrel (sold as one part). I replaced both of mine to a cost of around 300GBP so they're not cheap but was one of my best purchases two years ago! Here's some pccies of the barrel assembly
