I am thinking that the transponder portion of the keys work with the car to set up program mode and learn the third key. But does that process also get the third key to be able to work as a remote too where the active transmitter unlocks the car when I push the buttons? If so that is cool!
My mind immediately went to a workaround fix idea, but this post makes me think my idea won't work.
The only problem with my keys is that the buttons don't seem to unlock the car anymore. Right now I am manually locking the car with the car button before closing the door. When I unlock the car, I use a manual key and then have to die on to the car quickly to get the key in to the ignition to stop the horn/alarm from sounding off. Sucks. (Especially the extra noise from my wife saying I'm waking up the baby!)
My thought was I could buy ANY old key and pull the guts out and put in to my old housing. I would start the programming mode per instructions with the housings open on my keys. I do the first two normally, but then put the third guts in to the first physical key housing for the last step. The car wouldn't know if that was a third while key system, or a third guts in the first key blade housing. I thought I was real tricky in this thinking, but this post makes me think keys can only be programmed to a car once???
Thank you in advance for your thoughts and advice!
