Question about Buick Cars & Trucks
Having the vehicle checked for codes should have been the first thing done . Security light on ,a code is stored in the control module that controls the anti-theft system ! This is if you want it fixed right !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
DTC B2957 Security System Sensor Data Circuit Low
DTC B2958 Security System Sensor Data Circuit High
DTC B2960 Sec Sys Sensor Data Incorrect but Valid
DTC B3031 Security System Controller in Learn Mode
DTC B3094 No Response from ECM/PCM Received
or you can do a by pass that may or may not work ! You could measure the resistance of the pellet on the side of the key , then go to radio shack a by a resistor of the same value ! Then find the wires under the dash that come from the ignition switch ! Solder the resistor into the harness side wires , not going back to ignition switch . The wires break or contacts inside ignition switch do . You could check resistance with ohm meter . Put key into the ignition switch , find those wires i said about before . Check resistance at the wires under dash , is it the same resistance as pellet ?

if the security light is on it could be the ign lock cylinder, it has two small wires attached to it and one may be broken and are the keys the ones that came with the vehicle

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

Sadly no, there is no fuse or bulb to replace. You either have to send the instrument cluster out for repair or replace it with a new unit from the dealer. You could also obtain a serviceable one from a salvage yard. Most shops should be able to replace the instrument cluster or advise who can repair it.
