Need a locksmith for door/lock repair and possible replacement

I’m looking for a skilled locksmith to assess and fix a faulty door lock and handle at my property. The issue started after a jammed key and now the lock doesn’t engage properly. I’d like someone who can diagnose whether the lock needs repair or replacement, supply a compatible unit if needed, and ensure the door closes securely. Please include a brief inspection, any necessary drilling or alignment adjustments, and a clear estimate of costs. Access will be available during the day, and I’d prefer a same-day or next-day appointment if possible. Experience with standard UK door hardware and upgrades for security would be ideal.
