Open 24 hours, 7 days a week · Licensed, bonded & insured
Modern vehicle keys are far more than a metal blade — they contain transponder chips, rolling-code remote circuits, and in many cases proximity sensors that talk directly to your car's engine control unit. Getting that communication right requires professional-grade diagnostic tools and genuine knowledge of each vehicle platform. That's exactly what our insured, trained mobile technicians bring to your driveway, parking lot, or roadside stop, available 24/7 every day of the year.

Frequently asked questions
Can you program a key fob on location without towing my vehicle to a shop?
Yes — that is the core of our mobile service. Our technicians arrive at your location with OEM-compatible programming equipment capable of handling most domestic and import vehicles right in your driveway, parking lot, or roadside. You do not need to tow to a dealership or wait for a shop appointment. Once ownership is verified, we program and fully test the remote before we leave.
How much does key fob programming cost, and is there a call-out fee?
We do not publish fixed dollar amounts because the final price depends on several real variables: your vehicle's year, make, and model; the type of key (basic remote vs. push-to-start smart key vs. transponder chip key); whether cutting is also required; the time of day; and travel distance within Bexar County. What we do guarantee is a firm, confirmed price before any work begins — no hidden charges added after the fact. Call (210) 512-4768 for an exact quote specific to your vehicle.
Do you program fobs for all vehicle makes, including trucks and motorcycles?
We program remotes and transponder keys for a wide range of vehicles, including domestic trucks and SUVs, Japanese and European imports, motorcycles with electronic immobilizers, and light commercial fleet vehicles common throughout the San Antonio area. If you are unsure whether your specific model is supported, call (210) 512-4768 and our dispatch team can confirm before you book.
What happens if my only key fob is completely lost — can you still get me into my car and make a new key?
Yes. A completely lost key situation is one of the more complex automotive locksmith jobs, but it is well within our capability. We first verify your ownership of the vehicle, then use specialized equipment to access the car without damage where the platform allows, cut a new key blade if needed, and program a new fob from scratch directly to the vehicle's security module. The process takes longer than a simple spare-key duplication, which is one reason we encourage every driver to have a backup fob programmed before losing the original.
Is your key fob programming service available late at night or on weekends in Bexar County?
Our emergency locksmith service operates 24 hours a day, 7 days a week, including holidays. Whether you are locked out at midnight near downtown San Antonio, stranded at a gas station off I-35, or dealing with a malfunctioning remote early Sunday morning, call (210) 512-4768 and a real dispatcher will answer and get a technician moving toward your location.
Do you also handle mortise locks and other door hardware during the same visit as automotive work?
Our technicians are trained across both automotive and residential/commercial services. If you need a mortise lock repaired or a door knob lock re-keyed at your home or business in addition to an automotive key programming job, we can often address both in a single dispatch. Just let the dispatcher know everything you need when you call so the technician arrives prepared with the right parts and tools.
