Is your 2001 Toyota Tundra key fob not working, or did you get a new key fob and need to program it? This guide provides you with clear, easy-to-follow instructions on how to program your 2001 Toyota Tundra key fob for the RS3000 security system. Whether you’re adding a new remote or need to reprogram your existing one, this step-by-step process will help you get your keyless entry system working again quickly.
Before you begin, it’s crucial to verify that your 2001 Toyota Tundra is equipped with the RS3000 security system. This programming procedure is specifically for vehicles with this particular system. Using these instructions on a different system will not work.
To confirm if you have the RS3000 system, look for a security indicator light on your dashboard, similar to the one pictured below. This light is a key identifier of the RS3000 system.
Another way to confirm is to locate the RS3000 ECU (Electronic Control Unit) computer. This computer is usually found in one of several locations: behind the driver’s side kick panel under the dashboard, underneath the seats, or in the trunk. You might need to remove a plastic panel to access the kick panel area. Sometimes, it might be hidden under the carpet, but you should be able to feel its outline. The RS3000 ECU computer looks similar to the image shown here:
Important Note: It’s essential to use a BLACK remote with a BLACK remote system. These remotes are not interchangeable with other systems or remote colors. Ensure you have the correct type of key fob for your 2001 Toyota Tundra RS3000 system before proceeding with the programming.
How to Program an Additional 2001 Toyota Tundra Key Fob (RS3000 System)
If you are adding a new 2001 Toyota Tundra key fob to your RS3000 system, follow these steps:
-
Locate the RS3000 ECU Computer: As described earlier, find the RS3000 ECU computer in your 2001 Toyota Tundra. It’s crucial to access this unit for the programming process.
-
Turn Ignition to ON Position: Insert your key into the ignition switch and turn it to the “ON” position. Do not start the engine; simply turn the key to the position just before starting the car, where the dashboard lights illuminate.
-
Press and Hold Programming Button: Locate the programming button on the RS3000 ECU computer. PUSH and HOLD this button for 3 seconds. After holding for 3 seconds, the security light on your dashboard (the one you identified earlier) will turn on and remain lit for 5 seconds.
-
Press and Release Remote Button: Within that 5-second window when the security light is illuminated, take the first key fob you want to program. PRESS and RELEASE the top button on the remote. Once you press the button, the security light should turn off. You will also hear a chirp sound, and the exterior lights of your Toyota Tundra will flash once to confirm successful programming of that remote.
-
Turn Ignition OFF: Switch the ignition key back to the “OFF” position. Programming for this key fob is now complete.
-
Program Additional Remotes (Optional): If you have more 2001 Toyota Tundra key fobs to program (up to a maximum of 4), repeat step 4 for each additional remote. Make sure to do this within the same programming session.
How to Erase All 2001 Toyota Tundra Key Fobs from the RS3000 System
If you need to erase all previously programmed key fobs from your 2001 Toyota Tundra’s RS3000 system, perhaps due to security concerns or if you are starting fresh, follow these steps:
-
Turn Ignition to ON Position: Insert your key into the ignition and turn it to the “ON” position, just as you did for adding remotes.
-
Press and Hold Programming Button (First Time): Locate and PUSH and HOLD the programming button on the RS3000 ECU computer for 3 seconds. The security light will turn on for 5 seconds, just like in the add remote procedure.
-
Release, Then Press and Hold Again: RELEASE the programming button after the initial 3 seconds. Immediately PUSH and HOLD the programming button AGAIN for another 2 seconds. This time, when you hold it for the additional 2 seconds, the security light will turn off. You will hear a chirp sound, and the exterior lights will flash 3 times. These three flashes indicate that all previously programmed remotes have been successfully erased from the system’s memory.
-
Turn Ignition OFF: Switch the ignition key to the “OFF” position. The erasure process is now complete. None of the previously programmed key fobs will function with the RS3000 system until they are reprogrammed using the “Add Remote” procedure.
If you encounter any difficulties programming your 2001 Toyota Tundra key fob or prefer professional assistance, you can search for a local key fob installer in your area by entering your city or zip code in an online search engine. They can provide expert programming services to ensure your keyless entry system is working correctly.
