Acura RSX Key Replacement in Ventura County (2002-2006)

It depends on what you mean by 'program.' The remote buttons (lock, unlock, trunk) can be self-programmed using an ignition on/off sequence repeated three times, pressing the Lock button within four seconds each cycle. But here is the catch: every existing remote needs to be present during the process, or they get erased. And the transponder chip that actually lets your RSX start? That requires professional tools and a Honda immobilizer PIN. For the transponder side, call us at (805) 790-8162 and we handle it on-site.

Practically none. Both use the same standard blade transponder key with an Megamos 13 (ID13) chip and the Honda Immobilizer system. The Type-S sometimes came with a 4-button fob that adds a dedicated trunk button, but the programming process and chip are identical. We cut and program both versions on-site for $150 to $250, which is roughly half what the dealer charges.

Start with the CR1616 battery, but honestly, on these 2002-2006 fobs the membrane under the buttons wears out over time. If a fresh battery does not fix it, you likely need a replacement remote. We carry compatible fobs and can program them on-site anywhere in Ventura County. Just remember, if you self-program a new remote without all your other remotes present, the missing ones get erased from the system.

No. Same transponder chip, same immobilizer, same FCC ID, same programming method as the 2002-2004 models. The facelift brought updated headlights and some trim changes, but Acura did not touch the key system at all. The only minor difference is that 4-button fobs became more common on facelift models. We handle every RSX year the same way, whether you are in Moorpark or Ventura.
