I have a 2007 ST. I tried the instructions listed above and it doesn't work. I turn my key on and off 4 times and in the off position with the key in the ignition, it chimes.
Then I push the lock button on a remote and the headlights flash and the door locks cycle. I then try it for a second remote and nothing. I can only get this done for one remote and it's frustrating. Any suggestions?
**EDIT** Never mind, I'm good. I dug up my owners manual and got r done. The sequence was different than what was listed here.
