Are you looking to program a new key fob for your 2002 Toyota Corolla? This guide provides step-by-step instructions to program your 2002 Toyota Corolla Key Fob, specifically for vehicles equipped with the RS3000 security system. Whether you’re adding a remote or need to erase all previous remotes, follow these procedures to get your key fob working with your car again.
Identifying the RS3000 Security System
Before you begin programming your 2002 Toyota Corolla key fob, it’s crucial to verify that your vehicle has the RS3000 security system. This system is often referred to as a dealer-installed option, and the programming procedure outlined below is specifically for this type of system. Using this procedure on a different system will not work.
To confirm if your Corolla has the RS3000 system, check for these indicators:
-
Security Light Location: Locate the security indicator light on your dashboard. The position of this light is a key identifier for the RS3000 system.
-
Remote Appearance: RS3000 systems use a BLACK remote. It is important to note that black remotes are not interchangeable with gray remotes from other systems. Ensure your replacement key fob is a black remote to be compatible with the RS3000 system.
-
ECU Location: The RS3000 ECU (Electronic Control Unit) computer is another way to confirm the system’s presence. This computer is typically hidden but can be found in these locations:
- Behind the driver’s side kick plate under the dash. You may need to remove the plastic panel to access this area.
- Underneath the seats.
- In the trunk area.
- Often, it’s hidden under the carpet, but you might see its outline.
Once you have confirmed that your 2002 Toyota Corolla is equipped with the RS3000 system by verifying the security light and potentially locating the ECU, you can proceed with the programming instructions.

Programming a 2002 Toyota Corolla RS3000 Key Fob
There are two main procedures for managing your 2002 Toyota Corolla key fobs with the RS3000 system: adding a new remote and erasing all existing remotes. Choose the procedure that fits your needs.
Procedure to ADD a Remote
Use this procedure when you want to program an additional key fob to your 2002 Toyota Corolla RS3000 system. You can program up to 4 remotes.
-
Ignition ON: Insert your key into the ignition switch and turn it to the ON position. Do not start the engine, just turn the key to the position right before starting.
-
Press and Hold Programming Button: Locate the programming button, usually found on the RS3000 ECU. Push and HOLD this programming button for 3 seconds. After 3 seconds, the security light on your dashboard will turn on and remain lit for 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 wish to program. Upon successful programming, the security light will turn off, you will hear an audible chirp from the vehicle, and the exterior lights will flash once.
-
Ignition OFF: Turn the ignition switch to the OFF position. Programming for this remote is now complete.
-
Repeat for Additional Remotes: If you have more remotes to program, repeat steps 1 through 4 for each additional key fob. Remember, you can program up to a maximum of 4 remotes to the RS3000 system.
Procedure to ERASE ALL Remotes
Use this procedure when you want to clear all previously programmed key fobs from your 2002 Toyota Corolla RS3000 system. This is useful if you are concerned about security or have purchased a used vehicle and want to ensure only your remotes work.
-
Ignition ON: Insert your key into the ignition switch and turn it to the ON position, same as in the ADD procedure.
-
Press and Hold Programming Button (Initial Hold): PUSH and HOLD the programming button for 3 seconds. The security light will turn on for 5 seconds.
-
Release and Press and Hold Again (Second Hold): RELEASE the programming button, and then immediately PUSH and HOLD it again for another 2 seconds. After this second hold, the security light will turn off, you will hear a chirp sound, and the exterior lights will flash 3 times. This indicates that all previously programmed remotes have been erased from the system’s memory.
-
Ignition OFF: Turn the ignition switch to the OFF position. The erasure process is now complete. None of the previously programmed remotes will function with the RS3000 system until they are reprogrammed using the ADD procedure.
