Is your 1999 Toyota Corolla Key Fob not working, or did you get a new key fob remote and need to program it? You’ve come to the right place. This guide provides comprehensive instructions on how to program a 1999 Toyota Corolla key fob, specifically for vehicles equipped with the RS3000 security system. Whether you’re adding a remote or need to erase all existing remotes, we’ll walk you through the process step-by-step.
Identifying the RS3000 Security System in Your 1999 Toyota Corolla
Before you begin programming your 1999 Toyota Corolla key fob, it’s crucial to confirm that your vehicle has the RS3000 security system. This programming procedure is specifically for this “dealer-installed” system and will not work with other security systems.
The easiest way to check for the RS3000 system is to locate the security indicator light. Look for a small light, often red, on your dashboard. This security light is a key identifier for the RS3000 system.
Another important point to note is the type of remote. For the RS3000 system in your 1999 Toyota Corolla, you must use a black remote with a black remote. They are not interchangeable with remotes of a different color.
The programming process involves locating the RS3000 ECU (Electronic Control Unit) computer. This computer is usually hidden in one of several locations:
- Behind the driver’s side kick plate under the dash. You might need to remove the plastic panel to access it.
- Underneath any of the seats.
- In the trunk, possibly under the carpet.
You’ll be looking for a small box, and in order to proceed with the programming, you will need to locate the programming button on this ECU.
How to Program a New 1999 Toyota Corolla Key Fob (Adding a Remote)
Follow these steps to program an additional 1999 Toyota Corolla key fob to your RS3000 system:
- Locate the RS3000 ECU Computer: Find the ECU in one of the locations mentioned above (driver’s side kick plate, under seats, or in the trunk).
- Turn Ignition ON: Insert your key into the ignition and turn it to the “ON” position. Do not start the engine.
- Press and Hold Programming Button: Locate the programming button on the RS3000 ECU. Push and hold this button for 3 seconds. The security light on your dashboard should turn on for 5 seconds, indicating programming mode is active.
- Press Remote Button: Within 5 seconds of the security light turning on, press and release the top button on the first 1999 Toyota Corolla key fob you want to program. After pressing the button, the security light will turn off, you will hear a chirp sound, and the exterior lights of your Corolla will flash once to confirm successful programming.
- Turn Ignition OFF: Switch the ignition to the “OFF” position. Programming is now complete for this remote.
- Program Additional Remotes (Optional): If you have more remotes to program (up to a total of 4), repeat steps 2-5 for each additional 1999 Toyota Corolla key fob.
How to Erase All 1999 Toyota Corolla Key Fobs from the RS3000 System
If you need to erase all previously programmed remotes from your 1999 Toyota Corolla’s RS3000 system (for security reasons, for example), follow these steps:
- Turn Ignition ON: Insert your key into the ignition and turn it to the “ON” position. Do not start the engine.
- Press and Hold Programming Button (First Time): Locate and push the programming button on the RS3000 ECU. Hold it for 3 seconds. The security light will turn on for 5 seconds.
- Release, then Press and Hold Again: Release the programming button, and then immediately push and hold it again for another 2 seconds. This time, the security light will turn off, and you will hear a chirp sound and see the exterior lights flash 3 times. This indicates that all previously programmed remotes have been erased from the system.
- Turn Ignition OFF: Switch the ignition to the “OFF” position. Erasure is now complete. None of your previously programmed 1999 Toyota Corolla key fobs will function with the RS3000 system until they are reprogrammed.
