Front hood not closing problem

Hello friends, I just joined you. My car is 2004 model 307 sw. I opened the hood to look at the oil and water and I couldn't close it again. anybody come in? thanks in advance

Sometimes the lock spindle rotates automatically and the hood does not close, as the need for the open pit is closed. This may also happen on other doors. Check that part, pull back, it will close

Sometimes it can happen, as our friend says, or there is a key problem, you may need to change it.

Check your latch from the inside. The cable pulled by the latch may be broken or twisted. If you pull it out, you cannot manually release the tongue.
