My Daughter has a 2009 Astra, the car battery has died and she was never given the Emergency key when she bought the car some years ago. Is there any easy solution to open a door or the Bonnet ??

Physical Key was missing when car was purchased...Hence problem.

2009 Astra ?The issue is the Car Battery has no power to operate the Central Locking system and I cant access any + pos connections to get a feed to the Battery.
Thanks Harry, I am beginning to think the internal door release method is the only option, I have found that nylon parcel binding ribbon very useful for this in the past.
As with a lot of modern cars, you dont need a key to start the engine, the Key Fob just needs to be near the car.

Vrs . That starter is well buried thenI may try that, I didn't think there was a direct path between the Starter Motor +ve and the Battery ? The other problem may be getting underneath, it is the VRS version, so full body kit, very close to the ground and I am 17 stone !!
VXR maybe?VRS?
