Last accuracy audit: 2026-07-06
On 2026-07-06 an internal audit cross-checked a sample of our model-year coverage against NHTSA vPIC's GetModelsForMakeYear endpoint and found that our per-model year ranges were generated as a uniform 2002–2024 span for every model, rather than each model's actual production run. That means some vehicle-year pages on this site describe model years that were never sold in North America (confirmed examples: a 2002 Kia Telluride page — the Telluride didn't exist before 2020 — and a 2005 Ford Maverick page — the modern Maverick launched for 2022). The interim fix live now is the disclosure paragraph at the bottom of every vehicle page, reproduced below. The permanent fix — regenerating coverage per model directly from vPIC — is planned but not yet shipped; see the status note at the bottom of this page.
What's independently verifiable today
| Field | Source | Confidence |
|---|---|---|
| Make & model names | NHTSA vPIC public API | High — names are real |
| Model-year coverage (which years exist per model) | Uniform 2002–2024 placeholder, not yet validated per model | Low — known issue, see above |
| Transponder chip family & frequency | Manufacturer datasheets (NXP, Texas Instruments, EM Microelectronic) and the OBD2 community immobilizer database | Moderate–High, generation-level accuracy |
| FCC ID(s) | FCC public radio equipment authorization database | Moderate — sourced but not verified per exact trim/VIN |
| OEM part numbers | Documented parts-catalog prefix conventions per manufacturer | Low — suffixes/full numbers are illustrative, confirm at a dealer parts counter before ordering |
| Aftermarket programmer compatibility | Published vehicle-coverage lists from Autel, Xhorse, AutoProPAD, Topdon, Smart Pro, Abrites | Moderate–High |
| Pricing ranges | Aggregated from public retail and dealer-parts listings | Directional — expect regional variance |
Why this matters more here than on a typical reference site
Getting a key fob wrong is expensive: a mis-ordered OEM part or a wrong-generation aftermarket fob is a $30–$140 mistake that still won't start the car. Most sites in this space don't disclose sourcing at all, which makes their tables look more authoritative than they are. We'd rather tell you exactly which fields are dealer-counter-safe today and which are directional, than let a clean-looking table imply certainty we don't have.
Status: fixing the coverage issue
The planned fix replaces the uniform 2002–2024 placeholder with real per-model year ranges pulled directly from vPIC's GetModelsForMakeYear endpoint (one call per make/year — roughly 322 calls across our 14-manufacturer directory), then rebuilds the model selector, sitemap, and year tags to match. This is a multi-hour data-engineering pass, tracked internally; it has not shipped yet. Until it does, treat any single vehicle-year page's existence as "this make/model may have used this fob hardware around this year" rather than "this exact model year was definitely sold."
