I called to ask for pricing. A lady said there would be $19 service fee and $15-$39 price for the lock. She failed to mention a labor fee. When the service guy came, it cost $35-$50 a lock, the service fee was $20 and there was a labor fee $12 per lock. I had called another company that I've used before but used Empire because it was closer. Next time I will use E and S in Charlotte because they don't have labor fees, are reasonably priced and give Realtor discounts. I'm sure I overpaid.
