Residential lock change

I recently purchased a home and was informed that the previous owner had lots of visitors who all had keys to the back door. I was worried that an uninvited guest may show up at any moment so I wanted to change the locks. I was referred to North York Lock and Key and after my experience I can see why they came so highly recommended. The technician arrived on time for the appointment and got right to work he changed the locks on the exterior doors and re keyed the locks on the inside of the home all within a few hours. The price was less than what was quoted and the customer service was see second to none. I will definitely recommend to anyone else who is in need of a professional Locksmith in North York!
