Require locksmith help for a door lock issue in my flat

Hi there, I’m in a rental flat in Ireland and I’ve had a problem with my interior door lock. It won’t turn and the key seems jammed. I’m hoping to find a reliable locksmith who can assess the mechanism, open the door if needed, and replace or repair the lock if possible. I’d prefer someone who can bring spare parts and handle basic security updates to ensure the door is secure. Please let me know your availability, the approximate cost, and whether you need me to provide access details beforehand. Thanks!
