What year ranges does this Acura RSX Key Fob guide cover?

This Acura RSX Key Fob programming reference covers only two clusters: 2002 and 2003u20132006.

Does this Acura RSX Key Fob guide program the remote only or also the transponder?

This guide addresses keyless-entry remote transmitter enrollment into the keyless receiver unit memory. It does not cover immobilizer transponder key programming or tool-based security work.

What indicates that Acura RSX Key Fob programming worked?

The primary indicator during enrollment is hearing the vehicle door-lock actuators. After exiting programming mode, confirm proper operation of each transmitter.

What if the Acura RSX Key Fob programming steps do not work?

Re-check prerequisites (doors and hatch closed, aiming at the receiver under the audio unit, and 1u20134 second timing). If failures continue, a mobile automotive locksmith can perform an on-vehicle verification and programming attempt.

How many transmitters can be stored for an Acura RSX Key Fob setup?

The receiver memory supports up to three transmitters. If a fourth code is stored, the first-input code is erased, so all remotes expected to work should be tested immediately.

Acura RSX key types & programming facts

All 2002-2006 Acura RSX models for the U.S./Canada market use a conventional metal ignition key with an integrated immobilizer chip and a separate keyless entry remote fob. Programming involves registering the new key’s transponder to the vehicle’s immobilizer using appropriate equipment, and separately programming the keyless entry remote through an onboard procedure that cycles the ignition and uses the remote buttons. The vehicle is not push-to-start, and keyless entry remotes are limited to lock, unlock, and panic functions.

Key types used on the RSX:

standard metal key with transponder immobilizer chip (separate keyless entry remote) (2002-2006)

Common fob FCC IDs: OUCG8D-355H-A, E4EG8D-444H-A — check the back of your fob; we confirm the exact variant on site.

How we validate this guide

Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.
