Bonnet release issues

[AldoVP]

It appears as though I have an issue with my bonnet release.

I've been able to release the bonnet in the usual method to check my oil.

I am unable to shut the bonnet fully. The first catch engages but the bonnet will not lock into place all the way down.

The lever in the passenger footwell no longer appears to have any resistance to it.

It seems to me therefore that there are two issues:
1) Why is the bonnet not locking into place after slamming/pushing down? And how to fix this issue (obviously I dont want to drive around with an unsecured bonnet)?
2) I'm assuming that the release lever in the passenger footwell is broken, if so how to fix it?

Thanks in advance

First thing to check is whether the latch is stuck in the open position (so that only the secondary catch is working), which might just be a case of lack of lubrication (and would explain why the lever doesn't have any resistance).

Thanks Dave.

Seems as though that was 100% the correct answer.
