Key Operated Door Opener Required

[starmist]

Having tried to get into my 95 Griff today and found the battery as flat as a pancake, I also discovered that the key operated door opener was also u/s. Having got into the car with a coat hanger and plugged in my battery charger so I could get into the boot, I found that the plastic arm on the key lock is broken. It has the GM logo moulded into it, so I'm presuming it's a standard Vauxhall assembly.

Does anyone know if it's a boot lock or a door lock, and if it is possible to order one to suit my key?
