I don't have a car alarm for my car. Ok.... My problem started at first i couldn't unlock my rear door. Noticed the power locks continue to cycle a couple times when unlocking with remote. Then the problem moved to driver door. It wouldn't unlock with remote. I couldn't even turn it with the key which was odd. The passenger door unlocked though. So I decided to just crawl out the passenger side as it looks as i am not the only one.... LOL... I tried prying the door openby jiggling the driver door handle inside with some force. It finally opened. Now I have no play on my driver door handle. It will open and close until I drive somewhere and it sticks again.... Through this forum I found out that spring people were talking about was broke. I was told that the driver door actuator controls all doors by a co-worker... Is that true? Would that be the problem in the rear door too? But as for the starting thing. Since I had it, I cannot start the vehicle without clicking the unlock on my remote. Even if you press unlock on the door, it doesn't matter.... It has to be from the remote. But now I lost the remote. So it looks like I have to replace that spring on the drive door, plus program a new remote. Thanks for all the help. But is that unlock to start feature common?
