This depends on if its a factory alarm or not,if its factory then try using the key to unlock the door if it doesnt work on the driverside then unlock the passenger side door this is due to a bad door lock switch on the driver door, if its aftermarket you nned to look under the dash and find the wire for the starter coming down the steering column, you will see a yellow wire i belive the wire will be cut in half and connected to two diffrent wires, cut it and connect it back together and it will start you will then need to look further for fuses on alarm wires and remove the fuses as the alarm module is bad, a good way to tell its a factory alarm is the trucks horn is the siren, if this is the case then its probably factory and door switch is bad in the lock so try pass/side lock.hope this is helpful.

SOURCE: Security System has locked. Car will not start.

Try locking and unlocking the car with the key and not the remote. Sometimes this will disengage the alarm.

SOURCE: Security system disengages fuel pump

There might be a problem if it wont start on the first try?, preventing the injectors from flooding the cylinders. I would not attempt to disengage this.

Most of the time on GM vehicles, a "no start" can be traced back to the anti theft security system. When this system starts to fail, it will actually disengage the starter. THE HARD PART IS DIAGNOSING IT. Check out this link for info and some "do it yourself" solutions.

Alarm system wont disengage


Disconnect the battery.
Check the wiring (especially under the dash on drivers side fire wall) for shorts, disconnections, or loose or open circuits.
If no wiring problems are evident re-connect the battery.
If the alarm immediately starts resounding then you may have a problem with the security (box) itself that may have to be replaced.

Disengaged the security system however now when I go to start it it blinks security and shuts off but only when I go to start when i turn off the ignition it stops blinking. Its as if it is still...


The security system is connected with the ECU and ABS module. You can't disengage the system, if this is the OEM System. Rebuilt it and your Granny will run as long as you've fuel in your tank.
