Is your 1997 Toyota 4runner Key Fob no longer working, or did you purchase a replacement and need to program it? This guide provides you with clear, easy-to-follow instructions to program your 1997 Toyota 4Runner key fob yourself. Whether you’re adding a new remote or need to reprogram your existing one, this procedure is designed to get you back on the road quickly.
Before you begin, it’s crucial to verify that your 1997 Toyota 4Runner is equipped with the RS3000 security system. This system, often referred to as the “dealer-installed” system, is necessary for these programming instructions to work.
Identifying the RS3000 Security System
The programming procedure outlined here is specifically for the Toyota RS3000 security system. To confirm if your 1997 Toyota 4Runner has this system, locate the security indicator light on your dashboard. This light is usually a small LED that blinks when the security system is active. The presence of this security light, as shown in the image below, indicates that your vehicle is equipped with the RS3000 system.
Important Compatibility Note: Ensure you are using a black remote with a black remote system. These remotes are not interchangeable with other systems or remote colors.
Programming a 1997 Toyota 4Runner Key Fob (RS3000 System)
Follow these steps to program an additional key fob to your 1997 Toyota 4Runner RS3000 system:
-
Locate the RS3000 ECU Computer: This computer is the brain of your security system. It’s typically found in one of several locations:
- Behind the driver’s side kick panel (the plastic panel to the left of the pedals). You may need to remove this panel to access the ECU.
- Underneath any of the seats.
- In the trunk area, possibly under the carpet.
The ECU is usually hidden but you might be able to feel its outline under the carpet.
-
Turn the Ignition ON: Insert your key into the ignition and turn it to the “ON” position. This is the position just before you would start the engine, where the dashboard lights are illuminated.
-
Push and Hold the Programming Button: Locate the programming button on the RS3000 ECU. Push and HOLD this button for 3 seconds. After 3 seconds, the security light on your dashboard will turn on and remain lit for 5 seconds.
-
Program the Remote: Within those 5 seconds while the security light is on, PRESS and RELEASE the top button on the key fob you wish to program. If programming is successful, the security light will turn off, you will hear a chirp sound, and the exterior lights of your 4Runner will flash once.
-
Turn the Ignition OFF: Switch the ignition back to the “OFF” position. The key fob programming is now complete.
-
Program Additional Remotes (Optional): If you have more key fobs to program, repeat steps 2 through 5 for each additional remote. The RS3000 system can store up to 4 remotes.
Erasing All 1997 Toyota 4Runner Key Fobs (RS3000 System)
If you need to erase all previously programmed key fobs from your 1997 Toyota 4Runner’s RS3000 system (for security reasons, for example), follow these steps:
-
Turn the Ignition ON: Insert your key into the ignition and turn it to the “ON” position, just before starting the engine.
-
Push and Hold the Programming Button (First Time): Locate the programming button on the RS3000 ECU. Push and HOLD this button for 3 seconds. The security light will turn on for 5 seconds.
-
Release, then Push and Hold Again: RELEASE the programming button, and then immediately PUSH and HOLD it again for another 2 seconds. If successful, the security light will turn off, you will hear a chirp, and the exterior lights will flash 3 times.
-
Turn the Ignition OFF: Switch the ignition to the “OFF” position. All previously programmed key fobs are now erased from the RS3000 system and will no longer function.
