"I have a 2019 Cadillac and the one key fob I had was torn. Tim responded immediately, two new fobs working perfectly! I would highly recommend him for locksmithing, especially new fobs for vehicles."
Eric Rycus"Locked ourselves out on the weekend. Everyone else wanted $300+. Roman showed up, worked for a solid hour to unlock our door, then made us a new key on the spot. Much less money."
Bradley B."The dealership was going to charge me $380 for a new key and keep it for a day. Tim got me a working key with programming for less than half that price in 30 minutes. They know what they're doing and literally saved my money."
