Honda makes some programming easy and some equipment-only. Here's the breakdown by system.
Remote programming (many turn-key models)
Numerous Civic, Accord, CR-V and Odyssey models support an onboard remote sync using a driver-door/ignition sequence (a series of ignition on positions while pressing lock). The HON66/HO01 keyway is common on transponder and flip keys.
Transponder & Smart Entry
The immobilizer (transponder) side often needs equipment, and Honda Smart Entry push-to-start fobs (FCC families like KR5V2X, KR5V44, KR5TP-4, with Driver 1 / Driver 2 variants) require HDS or a capable aftermarket tool to register — particularly all-keys-lost.
Order the correct fob
