Changed Drivers entry door latch and now car won't start.

[zazoo]

Good morning all,

I recently changed my door latch on the drivers side and now the car won't start. The battery, alternator and kick are all good and just over a year old.

When I turn the key in the ignition, the lights, radio, control panel turn on. When I fully turn the key, it will not start the car.

I am based in Accra Ghana and have a local mechanic chap who try's his best but we just can't come around it.

When he uses his diagnostic machine we come up with the codes

1. EWS3.3 interface engine management-immobilized
2. CAN timeout transmission control unit

Initially I did get the car started after a few try's when the latch was changed and that was after the alarm system came on but now it's just not starting.

Any help from out here would be sincerely appreciated. Please help.
