Lacey Sherrice

I would like to thank ARC Locksmith Service. I have been calling around looking for someone to replace the keys for my car and they are the only one that said that they can. They came out the same day and the customer service both on the phone and in person was excellent. I look forward to using them when I purchase my new home. Again thank you so much for everything. I highly recommend this company for all your needs as a locksmith.

Ed Donohue

Great company! Call them first! Rob took care of my car in about five minutes and was a really great, friendly guy. Worth the price of having your car unlocked and back on the road. Will recommend to everyone and use again need be! Thank you! I’ve used ARC twice now and they are the best in the business. Truly great guys at a very reasonable price.
