After moving into a new house we requested a rekey through our home warranty company (One Guard) and they sent out Arco. They were absolutely fantastic. The tech was super nice and you could tell he knew his stuff! (I think his name was Jordan?) He came in a unmarked personal car but dressed very professionally. The reason I am knocking them down a start is due to their availability. I had to wait about a week after scheduling to get the job done.
On a side note, here is something I thought they could have done strictly for customer service reasons. With my rekey service through my home warranty I get 6 keyholes rekeyed and 2 garage door openers. I don't have a garage but I have 7 keyholes. When the tech came I was kind of expecting them to do the additional key hole at no charge due to the fact I didn't have any garage door openers needed and it literally took an additional 30 seconds. They charged me $12 for one additional keyhole. The whole entire job took less then 10 minutes and it cost me $69 for the home warranty service fee, plus $12 for the additional keyhole. I'm not complaining, but seeing how easy and simple it was I'm shocked he charged me as that would have been one easy way to make me a huge promoter of the company!
