2008 Toyota Highlander Key Fob Programming

[1Jesusfreak]

Can I program a 2008 toyota highlander key fob myself or do I have to take it to a dealer. If I can program it myself please could you please give me the proper instructions.

let me know if this works. it didn't for me.

I've been following the key insert and door opening sequence to program my key fob and can't get the car into program mode on my 2008 Highlander Sport. Is there some trick I'm missing? I can't get past step 10 after trying 30 times or more. Thanks in advance for your help.

Here's the sequence I'm following:

1. Start with the following conditions: You are in the drivers seat.
a. Key is out of the ignition
b. Driver door is open (all other doors closed)
c. Driver door is unlocked (other doors don't matter)
2. Insert and remove the key from the ignition twice within 5 seconds.
3. Close and open the drivers door twice within 40 seconds.
4. Insert the key into the ignition and remove it.
5. Close and open the drivers door twice within 40 seconds.
6. Insert the key into the ignition.
7. Close the door
8. Turn the key in the ignition on and then off.
9. Remove the key from the ignition.
10. The power locks should automatically cycle once to indicate that you have successfully entered program mode.
11. Within 40 seconds of the entering program mode.
a. press both transmitter lock and unlock buttons SIMULTANEOUSLY for a duration of from 1 to 1.5 seconds.
b. within 3 seconds, press the transmitter lock button for more than 1 second and release.
c. If the transmitter has been sucessfully programmed, the power locks will automatically cycle once. If they cycle twice, the remote has not been accepted.
d. If multiple remotes are to be programmed, repeat steps A-C.
12. Open the driver's door.

Thirdage2009,
Did you solve your problem? I need the same information as I bought a used 2008 Highlander Sport, and the used car dealer had only one key and fob. Thanks.
