Well one of my 2 remotes broke. so i ordered a replacement. when it arrived I learned it to the car and brain. But it does everything correctly except unlock the car. it will disarm the alarm but it will not unlock the doors like the other one. It arms and lock the doors, it remote starts the car, it just will not unlock it. It show it as disarmed and unlocked on the remote but i have to use the key. Any suggestions?
