Established in 2022 as an automotive-only locksmith, Auto Key SD in Point Loma dispatches mobile service vans from its Rosecrans Street shop with transponder programmers, laser key-cutting machines, and ECU reflashing tools. On-site key replacement covers vehicles from 1990 through current model years using OBD-II diagnostic scan-tool access to immobilizer systems — the same late-model platforms serviced mechanically by Dragonfly Automotive on the peninsula. Transponder chip programming supports Texas Instruments, Philips Crypto, Megamos, and proprietary OEM protocols, eliminating multi-day dealer waits and tow-truck requirements. Ignition cylinder repair, proximity-key shell swaps, and Honda/Acura/Toyota ECU reflashing extend the service menu beyond basic key cuts, with dispatch available in English, Spanish, and Arabic. Roadside lockout response averages 20–30 minutes across San Diego County, including scenes where towing operators like C&D Towing Specialists have already secured the vehicle. All-keys-lost situations — requiring full immobilizer resets, new transponder pairing, and ignition-cylinder replacement at the vehicle's location — represent the shop's most technical mobile jobs.
