My remote is stuck in
All you can do, for now, is to remove the battery, from the remote. This will at least allow for Non-remote operation. If that doesn't work, then the receiver is faulty, and you will have to bypass the unit, until it is repaired. Then you need to troubleshoot, your problem. Then you need to check, the button(s) aren't stuck, or some sort of contamination under the rubber buttons, and the switch "Fingers" on the board. They often get dirty and false trigger. Reset the master unit in the car, then code them again, and try it again. If it still will not work, then you will have to get it looked at by a professional, most likely you will need a new remote? But sometimes the receiver gets a spike from the cars power, and this causes it to go faulty.
