I'm in! Couldn't get to the starter motor but I was able to reach the +ve terminal on the alternator once I'd removed the cooling duct. It took a few tries to find a good earth but the alarm blasting my ears was the giveaway. The doors unlocked and the button on the dash popped the boot. The battery...

Thank you Astromorg, Jim, Allan

Allan's suggestion sounds promising. I have the wiring diagram and I'm looking at fig. 03.1. So I connect +ve to the thicker cable on the starter motor and any bare metal for -ve? Can I use a charger or should it be a booster battery?

When I turn the key in the door the interior handle moves as it should but doesn't release the lock.

It's a 2003 XKR convertible, btw...

Exactly that. I can't unlock the doors so I can't open the bonnet. The boot key turns freely but doesn't release the latch.

Hi Chris

I'm interested to hear how you resolved this, as I have the same problem but with the added twist of a flat battery. Dearly hoping the solution doesn't require any drilling of holes...

Thanks, Andrew
