    We cut the mechanical blade to your car's code.

  3. 3

    Program the immobilizer

    We code the chip to your vehicle's immobilizer system.

  4. 4

    We verify the engine starts and runs on the new key.

What to expect when we arrive

Here is what a visit looks like in Sunnyvale: a friendly, licensed technician arrives on time, assesses the situation in front of you, and explains your options in plain language. We confirm the price you approved, complete the work carefully, and then test everything together so you are confident it is done right. We are happy to answer questions and offer honest advice — leaving you informed, not confused.

Signs You Need Transponder Key Programming

Not sure if this is the right service? These are the most common situations that lead Sunnyvale customers to call us for transponder key programming:

  • Your car needs a chip key programmed
  • A non-programmed copy won't start the car
  • You lost keys and need immobilizer coding
  • You want a programmed spare

Every transponder key programming job in Sunnyvale is a little different, and we approach each one on its own terms. Rather than forcing a one-size-fits-all fix, we assess your specific door, vehicle, hardware or situation and choose the approach that solves the problem cleanly, safely and for the long term.

Key Benefits

  • Immobilizer chip keys programmed on-site
  • Add-a-key and all-keys-lost programming
  • Transponder, remote head and smart keys
  • Correct blanks cut and coded to your car
  • Verified start — not just a turning key

We use quality parts and proven techniques, not the cheapest hardware we can find. When a job calls for new components, we fit dependable, name-brand products sized correctly for your door or vehicle, so the repair lasts and keeps you secure well into the future.

A little prevention goes a long way. Once we have handled the immediate need, we are glad to point out simple steps that reduce the odds of a repeat — a spare key kept somewhere safe, a small hardware upgrade on a vulnerable door, or a quick adjustment that keeps a lock operating smoothly. Our aim is a lasting solution and a customer who feels genuinely looked after, not a quick job and a future callback.
