Bonnet will not open with key

Not sure if the solution can be applied to 2006 focus, I have an European Mk2 Focus which also having the same problem. Here is what you can try.

To Open:
1. Jack up the car on the lifter.
2. Open bottom engine cover.
3. Loosen two (10mm) screws which secure the bonnet lock assembly. The screws located between air manifold and radiator.
4. Once the screws released, disconnect the alarm cable/socket connected to the lock assembly.
5. Try pull open the bonnet, it may require little force to pull the bonnet open due to a little white plastic link (~1" long, plus (+)shaped) is still connected between the lock assy. and cable assy. Failure to release bonnet lock is only caused by this plastic link!
6. Once the bonnet opened, the cable assy can be detached by pulling it from engine side out. Inspect the plastic link if it worn out.

To Install:
1. Attach lock and cable assy. Ensure the plastic link is properly inserted in its place between lock and cable assy. Test the mechanism with the car key.
2. Insert the whole assembly from engine side out.
3. Secure with two 10mm screws, reconnect alarm cable.
4. Reinstall bottom engine cover.

Hope this help. Sorry for my English.
