one of the gates that AA Roosevelt Security System fixed for us started to get sticky and the key would not turn on one side. It had worked for weeks after, but anyways, called up AA Roosevelt, and the tech said he would come out and check it. He was running a tad late, but he called me in advance to inform me of that. How courteous! So he shows up fixes it, and even though to me, it was a separate service call, he said no charge! Best locksmith around, for sure.
