Ford ZX2 Escort 2000

[General]

Does anybody know why I can't use the keys of the car to open the trunk. The keys won't turn. THe only way i'm opening is it using the button under the steering wheel and somebody else has to manually lift the trunk. THe trunk release is electrical and it's not opening the trunk. Soon as you press it relocks the trunk, there has to be one person to press it and another to lift the trunk. Is the some kind of spring mechanisim that quickly lifts the trunk.
