Your lock has more and more trouble closing?
You are right to take the lead. You want to perform a replacement of your cylinder or lock for several reasons.
In some cases, such as theft or loss of keys your insurance is likely to reimburse you. My services are carried out with invoice so you will not have any problem to get you reimbursed by your insurer.
For this it’s very simple send me the photo of your lock on the inside and outside and your key. Your lock may only need a small maintenance or adjustment. If so, I make a trip to your home to diagnose your needs. My trip is free and do not commit you to anything. I will do the quote on the spot.
