2000 transit bonnet won't open no matter how hard i push the key any ideas?

If the bonnet of your 2000 Transit won't open despite applying pressure to the key, the issue may be with the latch mechanism or the cable connecting the latch to the release lever. Inspect for any visible signs of damage or corrosion around the latch area. You could try gently tapping on the bonnet while someone else pulls the release lever, which might help disengage a stuck latch. If these steps don't work, it might be best to consult a mechanic for further assistance.
