Early Honda and Acura keys can be duplicated by a cloning process, which is very economical. Later Vehicles, depending on model and year, switched to an encrypted transponder. Most of those can be cloned, but this is not as practical as programming extra keys to the car with diagnostic equipment. When using programming equipment, all keys must be present.

If all keys are lost, proper chip keys need to be originated, and the car must be programmed using diagnostic equipment. Exceptions are the '97 and up Preludes and the '96 and up RLs. With these, the immobilizer module can be reflashed, which is a service unique to specific locksmiths.

Some later models use proximity fobs (push button start) as either optional or standard equipment.

All Hondas switched to a sidewinder type key in 2003 (2002 for the CRV). Acura followed a few years later, dependent on model. We cut these keys every day.

We are able to duplicate and originate virtually all Honda and Acura chip keys.
