One day I forgot to turn off head light. So I must jump start my car. I found now when I park my car, I turn the key to off, the door lock **** does not change to open position. Usually when the key is turned off, the door lock open. I can open the door lock by press remote control open key twice. Before I only need to press one time. Now the lock-unlock switch on the left front door can work normally. Maybe there is a wrong signal store in the BCM(body control module). I try to clear the memory by loose battery's negtive terminal. But it does not work. Anyone can give some advice?

 

Do you have stock or aftermarket alarm?

 

it is an aftermarket alarm
