I was having problems with the technique of turning the key 10 times within 15 seconds to get the security system into program mode. I finally decided that perhaps the 15 seconds begins as soon as you close the door rather than when you start turning the key. With this in mind I got into the seat, got the key ready, closed the door, and immediately started flicking the key. In about 10 seconds I got the honk for program mode.
Here's the entire procedure. If you don't get the honk in step 6 then go back to the beginning.
- Press remote UNLOCK button to deactivate alarm
- Open driver's door
- Enter vehicle
- Close driver's door
- Within 15 seconds of closing the door, turn the ignition key to the ON position and back to LOCK position 10 times
- Horn sounds once to indicate programming mode activated
- Within 45 seconds:
- Open driver's door
- Close driver's door
- Press the LOCK button or UNLOCK button on one of the remotes
- Horn sounds twice to indicate remote programmed
- Repeat steps 8 thru 11 for each additional remote
- Once last remote is programmed remove ignition key from lock
- Horn sounds three time to indicate end of programming mode
- Check operation of all remotes programmed
