How to fix a stuck gear shifter on a Vauxhall Astra?

I'm having trouble shifting gears on my Vauxhall Astra. The gear shifter seems to be stuck and I'm not sure how to fix it. Any ideas?

It's possible that the gear shifter mechanism is jammed. Try to locate the release button underneath the shifter and push it while trying to shift gears.

Check the condition of the gear shifter cables. If they are worn or damaged, they may need to be replaced. It's a relatively simple DIY task.

It could also be an issue with the clutch. If the clutch is not engaging properly, it could make shifting difficult. Get it checked by a mechanic to fix any potential issues.
