Beware of Nationwide Call Centers
Many "locksmith" ads route you to out-of-state call centers that quote a low price, then send an unlicensed subcontractor who charges 3–5× more on arrival. Always get the full, total price upfront before anyone comes out — and confirm they're local and licensed.
We're a locally owned CT-licensed shop (CT #LCK.0000220) with a real address in Bethany. You talk to the owner, you get the real price, and a licensed tech shows up.
