Need urgent door lock repair and security check in home

Hi there, I’m looking for a handyman to handle a quick locksmith task at my house. The front door lock is sticking and sometimes won’t turn, and I’d also like a quick security check on the main entry to ensure there aren’t loose fittings or worn keys. Please provide an estimate for locking mechanism diagnosis, possible cylinder replacement, and a safe, compliant fix. I’d prefer a professional who can explain the issue in plain terms and has good reviews. Some flexibility on timing, but I’d like the repair completed today if possible. Access is easy through the front hallway and I can wait with a coffee while you work.
