Is your 2002 Toyota Corolla key fob no longer working, or did you recently purchase a replacement remote? Programming your key fob yourself can save you time and money compared to visiting a dealership. This guide provides clear, easy-to-follow instructions for programming your 2002 Toyota Corolla key fob, specifically for vehicles equipped with the RS3000 security system.
Before you begin, it’s crucial to verify that your Toyota Corolla has the RS3000 system. This particular programming procedure is designed exclusively for the RS3000 security system, often installed at the dealership.
Identifying the RS3000 Security System
To determine if your 2002 Toyota Corolla uses the RS3000 system, look for a security indicator light on your dashboard. This light is typically represented by a red LED and may be labeled “SECURITY”. The presence of this light, as shown in the image below, strongly suggests your vehicle is equipped with the RS3000 system.

Programming a New Key Fob (Adding Remotes)
This procedure will guide you through adding a new key fob to your existing RS3000 system. Ensure you have your new key fob and your vehicle key ready before starting.
-
Locate the RS3000 ECU: The Electronic Control Unit (ECU) for the RS3000 system is usually found in one of several locations: behind the driver’s side kick panel (the plastic panel to the left of the pedals), under the seats, or in the trunk. You might need to remove the kick panel to access it. It could be under the carpet, but its outline should be visible.
-
Turn Ignition ON: Insert your Toyota Corolla key into the ignition switch and turn it to the “ON” position. This is the position right before starting the engine, where the dashboard lights illuminate.
-
Press and Hold Programming Button: Locate the programming button on the RS3000 ECU. Press and hold this button for approximately 3 seconds. After 3 seconds, the security light on your dashboard should turn on and remain lit for about 5 seconds.
-
Press Remote Button: Within 5 seconds of the security light turning on, press and release the top button on the first key fob you want to program. Upon successful programming, the security light will turn off, you will hear a chirp sound, and the exterior lights of your Toyota Corolla will flash once.
-
Turn Ignition OFF: Switch the ignition key back to the “OFF” position. The key fob programming is now complete for the first remote.
-
Program Additional Remotes (Optional): If you have additional key fobs to program (up to a maximum of 4), repeat steps 4 and 5 for each additional remote.
Erasing All Existing Key Fobs (Deleting Remotes)
If you need to erase all previously programmed key fobs from the RS3000 system, perhaps for security reasons, follow these steps:
-
Turn Ignition ON: Insert your key into the ignition and turn it to the “ON” position, just as in the adding remote procedure.
-
Press and Hold Programming Button (Initial Press): Push and hold the programming button on the RS3000 ECU for 3 seconds. The security light will illuminate for 5 seconds.
-
Release, Then Press and Hold Again (Second Press): Release the programming button, and then immediately press and hold it again for another 2 seconds. This time, the security light will turn off, you will hear a chirp, and the exterior lights will flash 3 times, indicating that all previously programmed remotes have been erased.
-
Turn Ignition OFF: Turn the ignition switch to the “OFF” position. The erasure process is now finished. None of the previously programmed remotes will function with the RS3000 system until they are reprogrammed using the “Adding Remotes” procedure.
