Every time we try to start the car the alarm goes off, can't lock the doors, tried jump starting in case it was the battery, didn't work, tried unlocking and relocking with the remote but it didn't work, tried unlocking and locking with the key still the same, any suggestions
Disconnecting the battery isn't going to do anything , Having the electronic control module that is in control of the alarm system _ BCM - body control module ,check for DTC'S - diagnostic trouble codes is the way to find the problem . Your best bet , take your vehicle to a qualified repair shop. You have no idea of the complexity of the electrtonics .
Have you tried disconnecting the negative terminal from the battery post and waiting about 20 minutes before reconnecting it.
