When Your Key Won’t Turn, We’ll Figure Out Why
Your ignition switch does more than just start the car. It activates your fuel and ignition systems, powers your electrical accessories, and keeps your vehicle secure. When it starts failing, you may not get a lot of warning before you’re stuck in a parking lot at the worst possible time.
At TrustRock Automotive in San Antonio, TX, our ASE-certified technicians handle ignition replacement, car key replacement, and transponder key programming for all makes and models. We’ve been family-owned and operated for over 33 years, and we’re not in the business of replacing parts you don’t need.
Before we recommend any repair, we run a full diagnostic on your ignition system to confirm what’s actually wrong. You’ll get an honest report and a clear explanation of your options that comes with no pressure and no guesswork.
Has your key fob stopped working? Maybe your ignition switch has gotten stiff or sticky? No matter the ignition issue, we have the tools and experience to take care of it. We promise efficient service and all of our work is backed by our 3-year/36,000-mile warranty on parts and labor.
Call us at 210-641-2929 to schedule an appointment or ask about same-day service.
Common Signs You May Have a Faulty Ignition Switch
Ignition problems often start small and get worse. If you’re seeing any of these, don’t wait for a full failure before you have us handle ignition repairs.
Car Won’t Start
You turn the key and nothing happens. There’s no crank or no click. This is one of the clearest signs of an ignition switch failure.
Key Sticks or Won’t Turn
A key that’s stiff, sticky, or hard to remove from the cylinder usually points to wear inside the ignition or a damaged key.
Vehicle Stalls While Driving
If the ignition switch is failing internally, it can cut power to the engine unexpectedly, even at highway speed.
Flickering Dashboard Lights
A worn ignition switch can cause intermittent power loss, which shows up as flickering gauges or warning lights that come and go.
Accessories Stop Working
Radio, air conditioning, and other accessories that only run in certain key positions may cut out if the switch is worn.
Key Fob Isn’t Working
If your car’s key fob has stopped responding or the vehicle won’t recognize a programmed key, we can diagnose and reprogram it.

Ignition Cylinder Repair
When the lock cylinder itself is worn or damaged, not just the switch, we repair or replace it and make sure everything works together correctly.
What to Expect When You Bring Your Car In
Our skilled technicians follow the same straightforward approach whether it’s a simple key replacement or a full ignition switch job.
Step 1: Full Ignition System Inspection
We start with a thorough look at your vehicle’s ignition switch, cylinder, wiring, and key—not just the part that seems broken. Ignition problems often have more than one contributing factor.
Step 2: Honest Assessment & Clear Estimate
Once we know what’s wrong, we explain it in plain terms and give you upfront pricing before any work starts. No surprises when you pick up your vehicle.
Step 3: Repair or Replacement Using Quality Parts
We use high-quality parts and back our work with a 3-year/36,000-mile warranty. Our technicians have the tools and training to handle both simple and complex ignition jobs.
Step 4: Testing & Verification
After the repair, we test the ignition system fully, including any programmed keys or fobs, to make sure everything works before your car leaves our shop.
