I just noticed when I open the door that the rest of the doors don't unlock. Before when you were in the vehicle eventually all the doors would lock, this doesn't work and I'm not sure when but all the doors would unlock. Either opening the door or taking out the key. Any help would be appreciated.

 

Do you have an owners manual?

 

Yes and I tried the key off and on four times but I don't get the chime and nothing changes.

 

My 06 also quit doing this. I cant get it to reset and once while at the dealer they reprogrammed it and it lasted a month then quit again. I have a friend with an 06 also and her vehicle started having all kinds of electronic problems including the unlock issue. Then her PCM went out. Thankfully, my PCM has not went out and my key unlock issues started 5 years ago. SO I really think its an electronic issue.
