Car dealers often enjoy charging a lot of money for something a consumer can do easily. Programming a keyless entry system is no exception. Every Toyota is made with an onboard computer system that regulates the entire vehicle. The hardest trick is figuring out explain to the vehicle that you want to program a keyless system in it. The rule is this: You cycle your ignition switch to tell the car that you are going to program something to it. The car will automatically set itself to a programming mode, and from that point on it is just a matter of following the right sequence.
Instructions
1. Ensure the car doors are unlocked and open. Pull the key from the ignition.
2. Insert and remove the key from the ignition two times within five seconds. This will start the required sequence to reprogram the car's computer.
3. Close and open the driver's door twice within 40 seconds. This step has to be within that time, or the system will reset.
4. Insert the key into the ignition. Do not turn the key yet.
5. Cycle the key from lock to on. You will need to cycle this step one time for the add mode.
6. Remove the key from the ignition. Immediately grab the transmitter to complete the program.
7. Press both the lock and unlock buttons on your transmitter simultaneously for 1 to 1 1/2 seconds. Release the buttons afterwards.
8. Press the lock button within three seconds of releasing on the last step. This will complete the process. The door locks will cycle from lock to unlock if the process is done correctly. If there is a problem, the lock will cycle twice.
9. Open the driver's door. This will complete the process.
Tips Warnings
Check the batteries to ensure they are new. If you are programming multiple remotes, repeat the steps for each transmitter.
