Trying to program a new key fob?

I don't think there is a button on the ECM. It looks like there are two systems on this car which need to be identified.

Here are basic instructions with more detailed information below:

Start with the Car Off: Make sure your car is turned off with the key out of the ignition.

Insert and Remove the Key: Insert the key into the ignition and then remove it. This step is often repeated multiple times (usually twice) and needs to be done rapidly.

Close and Open the Door: Next, you typically need to close and open the driver's side door a couple of times. This step is also done in quick succession.

Cycle the Key in the Ignition: After the door step, insert the key into the ignition and turn it to the "On" position (right before starting the car) and then back to the "Off" position. This step might need to be done a couple of times.

Lock and Unlock the Doors: Use the door lock switch on the door to lock and then unlock the doors.

Push Remote Buttons: Finally, press and hold the button on the remote that you wish to program. You might need to do this for a few seconds until the car's locks cycle, indicating the remote has been programmed.

Turn Ignition to on: Once the locks have cycled, turn the ignition back to the "On" position to end the programming mode.

Test the Remote: After completing these steps, test the remote to see if it works.

Introduction

Difficulties during Remote Keyless Entry Transmitter Programming can arise due to confusion between Toyota Factory Wireless systems and Toyota Port/Dealer installed systems. This bulletin will assist in identifying the system/correct remote transmitters for each vehicle and provide the location of the most accurate programming procedure for each system.

Note:
Should a vehicle having both VIP and Factory systems available (as identified in the following Tables shown) be brought in without any remotes (or one non-working remote), use the following tips to help determine which type of wireless system (O.E. Or PIO/DIO) the vehicle has.

Look at the Trim Level of the vehicle. Higher-grade vehicles will tend to have O.E. Systems, while entry-grade vehicles will tend to have VIP. For example, the 2001 Camry XLE has Factory RKE, but the LE and CE grades have VIP.

Look for a "Status Monitor" with a glass breakage sensor and an LED externally installed into the dashboard or on the center console. Most VIP systems will have this.

Locate the ECU (refer to the applicable vehicle VIP Manual installation instructions for location). Once located, refer to the part label.

Attempt to perform the factory wireless programming procedure to get a response from the vehicle. Select the "confirmation mode" and see if any "Lock/Unlock" response is received, if so, the vehicle has a factory system.
