So my Grand Cherokee/ Laredo 2005 jeep's lock system has stopped working. It's like this, both the automatic lock system at the drivers seat and passenger seat have stopped locking/unlocking the car. Also my key's buttons don't unlock/lock the car. Rather I have to manually open the Jeep, this just happened suddenly I am not sure why..And by the way the automatic window buttons/ rest of the buttons on the driver and passenger seat are working fine. It's only the lock. Thank you for your time and answers!
