2004 trailblazer with electronic door locks how to open hood when you have a dead battery

SOURCE: electronic key won't work after dead battery???

If you have the Vehicle Owners Manual it will instruct you how to reset the Electronic Remote(s) as disconnecting the Battery or a totally discharged battery removes all power from the On Board Chassis Computers memory. Therefore you must reset the Remote(s) so that the On Board Chassis Computer can recognize them. If in Doubt, please consult your Chevrolet Dealer to rectify the problem.

SOURCE: the power door locks stopped

Sounds like body computer is malfunctioning or the module that controls the door locks lost it's program.Disconnect the battery for few minutes then reconnect and check.In some cases this resets the system computer and all starts working.But if that does not helps then problem has to be checked with the power door lock system.Either a power door lock actuator or the power door lock switch. Usually the most common problems with power door locks are the actuators. They are small electric motors used to lock and unlock the car doors when activated by a switch or remote. Like any electric motor sooner or later it will fail. Replacing an actuator involves removing the interior door panel for access. Some are part of the door latch and some are independent.
Either way, door lock actuators need to be replaced if they are buzzing, working only in one mode or are not working at all. if the problem is with the door lock actuator or just the switch. If a All the door locks, only work when locking and NONE of them work to unlock, then the switch is most likely the cause.
