Drivers door won't unlock from outside with GM PK3 key nor with Keyless FOB
After market Anti-Theft Receiver installed in Chevrolet Venture 2005 by dealer after purchase; Keyless FOB stopped working; Did online research; put new battery in; red light flashes when you press button, GM PK3 key works to start car, no problem there; so battery good & working; CANNOT open drivers door from the OUTSIDE and don't dare lock door after you get out as key won't work in outside door lock cylinder nor will Keyless Fob open it. So you are locked out of your car! Does door actuator have anything to do with opening door? Receiver gone bad? Keyless Fob not programmed right? Need some other educated guesses here. Thanks. Sandie
