Is your Toyota Camry key fob not working? Or perhaps you’ve purchased a new key fob and need to get it programmed to your vehicle? You’re in the right place. Programming your Toyota Camry key fob can often be done at home, saving you time and money compared to dealership programming fees. This comprehensive guide provides step-by-step instructions for programming your Toyota Camry key fob, covering both factory-installed and aftermarket keyless entry systems. Whether you drive a model from the late 90s or early 2000s, this guide will help you get your key fob working again quickly.
Before you begin, it’s important to ensure you have the correct type of key fob for your Toyota Camry. This guide assumes you are working with a compatible key fob, possibly a replacement like this original factory Toyota fob. It’s also crucial to distinguish between a master key and a valet key, as programming procedures typically require a master key. A master key will typically have a Toyota logo and can operate all locks, while a valet key may not open the trunk or glove compartment.
This guide covers two primary methods for Toyota Camry key fob programming: one for factory-installed systems and another for aftermarket or dealer-installed systems. Choose the procedure that best matches your vehicle’s keyless entry system type.
Procedure #1: Programming for Factory Installed Keyless Entry Systems
This procedure is designed for Toyota Camrys that came with a factory-installed keyless entry system. These instructions are generally applicable to Toyota models from the late 1990s and early 2000s, including:
- Toyota 4Runner (1999-2001)
- Toyota Avalon (1998-2004)
- Toyota Camry (1998-2002)
- Toyota Highlander (2001-2003)
- Toyota Land Cruiser (1998-2002)
- Toyota MR2 (2000-2005)
- Toyota Sienna (1999-2003)
- Toyota Sequoia (2001-2002)
- Toyota Solara (1999-2003)
Follow these step-by-step instructions carefully to program your Toyota Camry key fob:
-
Start Preparation: Ensure your driver’s door is open, all other doors are closed, and the driver’s door is unlocked. Remove the key from the ignition.
-
Insert and Remove Key: Insert your master key into the ignition (do not turn it) and immediately pull it out.
-
Perform Door Lock Cycles (Within 40 seconds): Using the power door lock switch on the driver’s side door, perform 5 lock/unlock cycles, starting with the “lock” action. Maintain a consistent pace, approximately one cycle per second (one cycle equals one lock and one unlock).
-
Open and Close Driver’s Door: Close and then reopen the driver’s door.
-
Door Lock Cycles Again (Within 40 seconds): Repeat the 5 lock/unlock cycles using the power door lock switch, again starting with “lock” and maintaining a consistent pace.
-
Insert Key and Turn Ignition (Twice):
- Insert the key into the ignition cylinder.
- Turn the ignition to the “ON” position (Do NOT start the engine) and then back to the “OFF” position.
- Repeat this “ON” to “OFF” ignition cycle one more time.
-
Remove Key: Remove the key from the ignition.
At this point, within 3 seconds, the power door locks should automatically cycle (lock then unlock) once. This indicates that you have successfully entered programming mode. If the door locks do not cycle, return to step 1 and repeat the procedure, ensuring you perform the steps within the time limits.
-
Program the Remote (Within 40 seconds):
- Press and Hold Both Buttons: Press and hold both the “lock” and “unlock” buttons on your new remote simultaneously for 1 second.
- Press and Hold Lock Button: Immediately after releasing both buttons, press and hold only the “lock” button for 2 seconds.
Within 3 seconds, the door locks should cycle once again, indicating successful programming of your key fob remote. If the door locks do not cycle, or if they cycle twice, repeat steps 8a and 8b. This indicates that the remote was not accepted, and you need to try programming it again.
-
Program Additional Remotes (If Necessary): If you have additional remotes to program, repeat step 8 for each new remote.
-
Exit Programming Mode and Test: Open the driver’s door to exit programming mode. Test all programmed remotes to ensure they are working correctly. Programming is now complete.
Procedure #2: Programming for Aftermarket / Dealer Installed Keyless Entry Systems
If your Toyota Camry has an aftermarket keyless entry system, or one installed by the dealer that is not factory original, the programming procedure is different. These systems often have a separate ECU (Electronic Control Unit) programming receiver.
Locating the ECU Programming Receiver:
The ECU Programming Receiver’s location varies depending on the specific aftermarket system installed. However, common locations include:
- Underneath the Front Seats: For most vehicles, check underneath either the driver or passenger front seat.
- Behind the Driver’s Dash: In some vehicles, it may be located behind the driver’s side dashboard. You might need to gently pry out a small black faceplate (approximately 5″x3″) located behind the mirror control switch to access it. Consult your aftermarket system’s owner’s manual for the precise location if available.
Once you have located the ECU Programming Receiver, follow these steps:
-
Turn Ignition ON: Insert your key into the ignition and turn the ignition to the “ON” position (Do NOT start the engine).
-
Activate Programming Switch: Locate the programming switch on the ECU receiver. Press and hold this switch for approximately three (3) seconds. If you are successful, a Status Monitor LED (light) on the ECU should turn on for about five (5) seconds. This light indicates that the system has entered programming mode. Refer to your aftermarket system’s owner’s manual for the exact location and appearance of the programming switch and Status Monitor LED.

-
Program Remote: Press and release either the “LOCK” or “UNLOCK” button on the key fob remote you want to program. Upon successful programming, the Status Monitor LED on the ECU will turn OFF, and the vehicle will typically provide a signal, such as sounding the horn and flashing the exterior lights. This confirms the remote has been successfully programmed.
-
Program Additional Remotes: To program additional remotes, repeat steps 2 and 3 for each remote.
-
Exit Programming Mode: Turn the ignition to the “OFF” position to exit programming mode.
-
Test Remotes: Test all programmed key fobs to ensure they are functioning correctly, locking and unlocking the doors as expected. Programming is now complete.
By following these procedures, you should be able to successfully program your Toyota Camry key fob and regain keyless entry functionality. If you encounter difficulties, double-check each step and ensure you are using a compatible key fob and master key where required. For aftermarket systems, consulting the specific system’s manual is always recommended for detailed instructions and troubleshooting tips.
