Fast, professional automotive locksmith services across San Antonio — car lockouts, key replacement, ignition repair, and transponder programming. Available 24/7.
From emergency car lockouts to high-security transponder programming — our certified technicians handle every automotive lock and key challenge in San Antonio.
Need a spare? We duplicate car keys on-site for virtually every make and model — from basic blade keys to transponder chip keys — fast, accurately, and affordably.
Modern vehicles require transponder chips to start. We program transponder keys, key fobs, and push-to-start remotes using OEM-grade equipment — ensuring your vehicle recognizes the new key first time.
Lost all your car keys? We create replacement keys from scratch using your VIN or lock cylinder — no original needed. Faster and significantly cheaper than the dealership.
Expert ECU and module programming for all makes and models. We use professional OBD-II tools to program or relearn immobilizer modules, BCMs, and other vehicle control units on-site.
Key stuck in the ignition? Ignition cylinder worn out? We diagnose and repair ignition problems on-site, replacing cylinders and extracting broken keys without needing a full engine teardown.
