What this fob type means in practice
The Integrated Transponder Fob appears across 1396 model-year pages in our directory, spanning 14 manufacturers. A traditional metal-blade key combined with an RKE remote in a single "flip" or "head" assembly. Includes a passive immobilizer transponder chip. Most years are eligible for onboard pairing with one working key.
Programming difficulty
Integrated transponder fobs are the friendliest form factor for DIY pairing. Most model years allow onboard procedures: insert your already-paired working key, cycle the ignition through ON-OFF a specific number of times, then press a button on the new fob within a strict timing window. Total time investment: three to five minutes once the new fob is in hand.
What you'll spend
Aftermarket transponder fobs typically run $25–$60 for the assembled fob; OEM units from a dealer cost $120–$220 for identical hardware. The savings are substantial enough that even one DIY pairing pays for the time you spend reading our per-vehicle page.
Common chip families
Most transponder fobs use one of the established Hitag2 / DST-class chips: NXP PCF7936 / PCF7937, Texas 4D63 (40-bit or 80-bit) / 4D67, or NXP PCF7961 (Honda's ID46). Aftermarket programmer support is mature for all of these — the chip rarely limits which programmer you can use.
