Central locking, date reset and external boot catch broken

Believe it or not I think it's supposed to do that. I believe it's to do with the fact that its not being locked/unlocked by the fob but I'm not sure. The BSI powers down after 60 seconds so I'd say that has something to do with the door locking cycle. I know you meant a figurative "5 minutes" but you'll find it's closer to 60 seconds. You'll be able to hear a quite audible click from the glove box when the BSI powers down.
I have never heard of this before but it makes sense as a "fail safe" if your fob stops working. There are manual locking devises in each of the doors in case the battery fails but I never thought what you would do if just the fob failed? I've owned a C2 for 15 years (only just picked up two C3's) and never come across this. Interesting.
What is your regiment for locking the car when you are not in it?

It's good to know that's a feature and not a fault. I was starting to think I may have bitten off more than I can chew. I currently get out and lock the doors manually with the catch inside the doors. A bit of a pain but it gets the job done until I can fix the car. I've got a Haynes manual ordered and a key fob tester so I should know soon if the fault lies with the key fob or with the car. I'll update this thread as I find out more in case anyone else has a similar issue.

You could just take the key to Timpson's, who would probably test you fob for nothing.

However the central locking isn't working, but when I'm in the car with the engine running and I press the lock button on the dashboard all the doors look so I know the wiring and locking motor works fine. I've put a new battery in the key fob but that hasn't changed anything.

I've also noticed the date and time always resets to midnight 1st of January 2004 when I fire it up and that the external boot release button won't work untill I've fire the car up.

There appears to be no sputtering when I turn the engine on and it starts up fine every time (although I've only owned it a few days so take that as you will) so I think the battery itself is okay. Because of this I'm wondering if theres corrosion on the battery terminals that would be causing these issues?
The car has the stock radio so I'm pretty sure it's not a poorly fitted radio pulling power.

I know very little about cars, but this seems like a reasonable assumption to me. Is there something else I've missed that would be a more likely cause?
