744 Polhemus Rd, San Mateo“We needed a repair on a door lock that is about 15 years old and no longer in production. Diamond sent out a locksmith who took a look at the lock and did some research to find a replacement part. The next day he came back with the replacement part and got the lock working like new. I appreciate the excellent customer service we received from Diamond Locksmith.“
“Kyle took care of an issue I had with a locking mechanism for my overhead rack. Great service!“
