We decided to install extra deadbolts on both our entry doors just to be safe after we heard there was few breaking attempts in our neighborhood. Rafael from Denver Lock & Doors was the one who handle the project, he came out on time, installed the new locks and rekeyed all the existing locks to match the new key, all in about one hour. He also made us several copies of the new key and double-checked all keys were working right, excellent service from start to finish, highly recommend this company.
