Chevrolet Key Fob Programming San Jose — Silverado, Equinox, Tahoe & More
GM's Transponder System: Passlock, Passkey, and PK3/PK3+
General Motors has used several generations of transponder-based anti-theft systems across Chevrolet models. Understanding which system your vehicle uses determines how programming is done:
- Passlock (1996–2006): Resistance-based system using a sensor in the ignition cylinder. Found on older Malibu, Cavalier, and early Silverado. No chip in the key itself — the security is in the lock cylinder.
- Passkey III / PK3 (2000–2008): Transponder chip embedded in the key head. The BCM must recognize the specific chip frequency before allowing the engine to run. Common on Silverado, Suburban, Tahoe, and Trailblazer of this era.
- PK3+ (2003–2012): Enhanced version with rolling code technology. Used on Equinox (first gen), Impala, and 2003–2007 Silverado. Requires OBD-II programming — cannot be done via DIY self-learn.
- BCM-based Smart Key / PEPS (2013–present): Push-to-start models (Tahoe, Traverse, Camaro SS, Silverado High Country) use a proximity key paired directly to the Body Control Module via GM TECH2-compatible interface.
Our mobile unit carries programming coverage for all generations. Whether you're driving a 2005 Silverado with a PK3 blade key or a 2023 Tahoe RST with push-to-start, we have the tools and blanks on hand.
Chevrolet Models We Service Most in San Jose
These are the Chevy vehicles we see most frequently at job sites, shopping centers, and residential calls across the South Bay:
- Silverado 1500 / 2500HD / 3500HD: The most common work truck in the region. Contractors, plumbers, electricians, and landscapers rely on these daily. We service all cab configurations (regular, double, crew) and all trim levels from Work Truck through High Country.
- Equinox: One of the highest-volume calls we get — very popular in Silicon Valley for daily commuting. Key fob battery replacement and BCM reprogramming are both common needs.
- Malibu: Older PK3 models frequently need transponder key duplication. We cut and program on-site.
- Tahoe / Suburban: Large family SUVs common in Almaden, Willow Glen, and Los Gatos. Push-to-start smart key programming from $175.
- Traverse: Three-row family hauler. Smart key fob programming for 2018–2024 models.
- Camaro: Both V6 and SS variants. The Camaro's keyless entry is tied to the BCM — straightforward OBD-II programming once we have your ID and registration verified.
- Colorado / Blazer / Trax: Mid-size and compact options we service regularly.
Silverado on the Job Site — We Come to You
A locked Silverado at a construction site doesn't just strand you — it can shut down a whole crew's workday. We get calls from contractors across San Jose, Santa Clara, and Milpitas who can't afford to wait at a dealer or arrange a tow. Our response time to most South Bay industrial and job-site locations is 30–45 minutes.
We verify ownership on-site (title, registration, or work vehicle documentation), then program a new key or reprogram an existing fob while you're standing there. Trades customers with fleet vehicles should have the vehicle's registration or fleet documentation ready at the call.
What to Prepare Before You Call
- Vehicle registration or title in your name (or fleet documentation)
- Government-issued ID matching the registration
- VIN number (dashboard or door jamb sticker)
- Any existing working keys (speeds up the process)
- Your current location — we come to you

Losing your only key to a Chevrolet is more common than you'd think — especially with work trucks that get heavy daily use. We can generate a new key from your VIN using OBD-II access to the BCM. This process requires:
- Physical access to the vehicle (we can assist with lockout entry first)
- Proof of ownership verified on-site
- OBD-II port access (under the dashboard, driver's side)
