Last week my bonnet latch light came on (I have a 06 ST3) so I bought a new one from ford and replaced it myself. Anyway, today my guages reported I needed to put more oil in (I recently had a new turbo fitted), anyway, when I tried opening the bonnet nothing happened? it wont open. I know I fitted everything correctly, I am totally lost, do I need to program the key or should it know when I started the engine after fitting the part.

Please advise??????
