Called this company to have an additional lock fitted after security had been compromised. Jack quoted a price and a time. Job was done to full satisfaction on time. I would recommend as we all want a reliable tradesman that you can trust.

Excellent service. Really quick and efficient. We rang at 4 to change a lock and he was out within an hour. Couldn't ask for better!

Very impressed with Jack's service - my key jammed in the lock when I arrived home yesterday evening (with my cat in her carrier making the experience extra fun). I found Keystar after looking online for a well-reviewed local locksmith. Jack was with me in around 30 minutes. He had to resort to drilling the lock out but got me and my cat into the house within 15-20mins before replacing the entire lock. Professional, efficient and friendly - would recommend Keystar highly, and I have already passed his details on to a family member.
