What an automotive locksmith actually does
Modern car keys are not just cut metal. From roughly 2002 onward, every mainstream make embeds a transponder chip in the key head that the immobiliser checks before the engine cranks. From 2010 onward, proximity (smart) keys with rolling-code RF pairing became standard. Cutting the metal is now the easy part — the cost and complexity sits in the chip, the programming, and the OEM-level diagnostic tools needed to enrol a new key with the car's body control module.
That's why a dealer quote for a lost key on a 2020 Honda CR-V comes back at $750-$1,100. They're charging for an hour of bench-time on a tool they only use for that purpose. A mobile automotive locksmith with the same OEM-protocol programmer (Autel IM608, Smart Pro, Tango) does the same job in your driveway for $280-$420 — same chip, same software, same result.
