This is what I found to reprogram the 2nd generation xb keys

I HAVEN'T TRIED THIS OUT YET BUT I FOUND THIS POST THAT SOMEONE HAD, LET ME KNOW IF IT WORKS BECAUSE I'M ORDERING A KEY IN THE NEAR FUTURE.....

Here are the procedures to manipulate the remote door lock system. As you can see they are hardly difficult programming exercises. Any competent mechanic should be able to do it in 20 minutes including time for paperwork, coffee, sharing a dirty joke with the next guy, and a cigarette break. Competence, in this case, means the ability to read and follow instructions, not even knowing anything about cars.

As with anything, try these at your own risk. If you accidently reprogram your engine to produce 200HP don't blame me!

There are four different modes you can use to program remote door lock functions.

Confirmation mode allows you to check the number of transmitters recorded.
Add mode allows you to add a transmitter without disturbing existing transmitters.
Rewrite mode allows you to replace all existing transmitters with new ones.
Prohibition mode erases all transmitters and turns off the remote door lock function.


Confirmation mode. To check for the number of remotes programmed into the car:

Start with the key out of the car, driver's door open and unlocked.

1.Insert key in ignition and pull out
2. Within 5 seconds, insert the key in the ignition and pull out again.
3. Within 40 seconds, close and open the driver's door twice, then insert and remove the key from the ignition again.
4. Within 40 more seconds, close and open the driver's door twice, then insert the key in the ignition and close the driver's door.
5. Turn ignition switch from LOCK to ON to OFF three times, leaving the key on for one second and off for one second each time.
6. Remove the key from the ignition lock.

The doors will lock and unlock themselves at about 2 second intervals. The number of times that the doors lock is the number of remotes that are programmed into the car. If the car locks/unlocks 5 times, there are no codes registered.


Add mode. To add a remote without disturbing existing remotes:

Start with the key out of the car, driver's door open and unlocked.

1.Insert key in ignition and pull out
2. Within 5 seconds, insert the key in the ignition and pull out again.
3. Within 40 seconds, close and open the driver's door twice, then insert and remove the key from the ignition again.
4. Within 40 more seconds, close and open the driver's door twice, then insert the key in the ignition and close the driver's door.
5. Turn ignition switch from LOCK to ON to OFF, leaving the key on for one second and off for one second.
6. Remove the key from the ignition lock.

The doors will lock and unlock themselves once.

7. Within 40 seconds, press the lock and unlock buttons on the transmitter at the same time and release.
8. Within 3 seconds, press either switch and release.

The doors will lock and unlock themselves once if the registration was successful. They will lock and unlock twice if the registration failed.

9. If you have other remotes to program, go back to step 7 within 40 seconds.
10. Insert the key in the ignition or open a door to complete registration.


Rewrite mode: To erase all remotes and add new ones:

Start with the key out of the car, driver's door open and unlocked.

1.Insert key in ignition and pull out
2. Within 5 seconds, insert the key in the ignition and pull out again.
3. Within 40 seconds, close and open the driver's door twice, then insert and remove the key from the ignition again.
4. Within 40 more seconds, close and open the driver's door twice, then insert the key in the ignition and close the driver's door.
5. Turn ignition switch from LOCK to ON to OFF twice, leaving the key on for one second and off for one second each time.
6. Remove the key from the ignition lock.

The doors will lock and unlock themselves twice, indicating that you are in rewrite mode.

7. Within 40 seconds, press the lock and unlock buttons on the transmitter at the same time and release.
8. Within 3 seconds, press either switch and release.

The doors will lock and unlock themselves once if the registration was successful. They will lock and unlock twice if the registration failed.

9. If you have other remotes to program, go back to step 7 within 40 seconds.
10. Insert the key in the ignition or open a door to complete registration.



Prohibition mode: To erase all codes and disable wireless door lock function:

Start with the key out of the car, driver's door open and unlocked.

1.Insert key in ignition and pull out
2. Within 5 seconds, insert the key in the ignition and pull out again.
3. Within 40 seconds, close and open the driver's door twice, then insert and remove the key from the ignition again.
4. Within 40 more seconds, close and open the driver's door twice, then insert the key in the ignition and close the driver's door.
5. Turn ignition switch from LOCK to ON to OFF five times, leaving the key on for one second and off for one second each time.
6. Remove the key from the ignition lock.

The doors will lock and unlock themselves 5 times at about 1 second intervals.
