try turning your steering wheel from left to right while you gently try removing the key. if that doesnt work and your car is a automatic with the shifter in the center console there is a cable running to the transmission that sometimes becomes loose causing the car not to be fully into the park position.
Let's get this straight , when you turn the key to the start position ,what happens ? Does the starter engage an spin the engine ? Or not . If you what help you need to give better descriptions . You turn the key on an the dash light come on , do the warning light's go off after a few seconds ? Is the anti-theft system light on an then goes off . Do the headlamps work , an shine bright ? Viewing a wiring diagram of the starter electrical circuits to see what it takes to make the starter spin the engine would also be a good idea . It just so happens the starter is computer controlled .
Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S terminal of the starter. Ground is supplied through the engine block.
Your best bet , have it towed to a qualified repair shop.
Circuit Description
This ignition system does not use a conventional camshaft position (CMP) sensor that detects valve train position. The ignition control module (ICM) detects when #1 or #3 cylinder has fired on the compression stroke using sensing circuitry integrated within each coil. The sensing circuit detects the polarity and the strength of the secondary voltage output. The higher output is always at the event cylinder. The ICM sends a CMP signal to the engine control module (ECM) based on the voltage difference between the event and waste cylinder firing energy. This system is called compression sense ignition. By monitoring the CMP and crankshaft position (CKP) signals, the ECM can accurately sequence the fuel injectors. If the ECM receives an intermittent CMP signal from the ICM, DTC P0341 sets.
Diagnostic Aids
• If DTC P0336 is set, diagnose that DTC first. An intermittent fault in the CKP circuit will cause the ECM to resync the cam and may set DTC P0341.
• An intermittent short to voltage on the CMP signal circuit can set this DTC. A direct short to voltage on the CMP signal circuit will set DTC P0340, as there will be no change in the cam signal input.
• The following conditions may set this DTC:
- High resistance in the #1 secondary ignition system
- Low resistance in the #4 secondary ignition system
- Corroded or loose #1 or #4 secondary ignition components
- Harness being routed too close to the secondary ignition components, relays, motors
If this DTC is determined to be intermittent, refer to Intermittent Conditions .

System OK
The locks don't work from any switch or just the driver's door switch ? The door locks are controlled by the BCM - body control module , that's were the clicking you hear is coming from there are no fuse's that are marked for the locks , fuse's for the BCM .
Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• BCM -- Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• BCM PWR 15A fuse -- Located in the BCM fuse panel, supplies power for the door lock system
The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.
Body Control Module (BCM)
Lower center of the I/P, just below the HVAC control assembly
Try pulling the steering wheel back and forth while trying to take the key out. Or, push forward and back on the shifter while it's in park, while trying to take the key out. This could be the steering wheel lock mechanism.
If you think it needs lubrication, try a LITTLE bit of graphite lubricant. Do NOT use WD-40.
What pump are you checking an fluid level ? Your vehicle has electric power steering an has no pump or fluid .
Your best bet , take it to a GM dealer , had recall on parts of the EPS , electric power steering (EPS) system .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
It could be the electronic power steeirng module . With the gauges dropping out like that , the module could be bring down the data bus . Don't know how much you know about automotive electronic's an how the insturment cluster know's what speed to set speedo at an how full fuel gauge is an rpm on the tach .
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM calculates the vehicle speed based on the class 2 message indicating the wheel reference speed from the electronic brake control module (EBCM) if:
• The ECM/PCM detects a malfunction in the vehicle speed sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM/PCM.
The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of class 2 communications with both the ECM/PCM.
012 GM Class II Communications
Checking the vehicle modules for DTC'S - diagnostic trouble codes is the first place to start .
The Power Steering Control Module (PSCM) receives a class 2 vehicle speed message from the Engine Control Module (ECM) via a class 2 serial data circuit. The PSCM uses this vehicle speed message, and other inputs, to determine the desired amount of steering assist.

Brake Fluid Level Switch
Try a auto salvage yard > Couple of buck's
Brake System Indicator
The instrument panel cluster (IPC) illuminates the brake indicator when the following occurs:
• The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination. If the vehicle is shifted out of park with the park brake engaged, the BCM activates an audible warning.
• The body control module (BCM) detects a low brake fluid condition (signal circuit is low). The IPC receives a class 2 message from the BCM requesting illumination.
• The IPC detects a low brake fluid condition (signal circuit is low).
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
could be no fuel pressure for the injectors
could be no spark and the apparent trying to start is from the compression ignition of the starter fluid
best have the fault codes read first to determine the area of failure
It shouldn't, they are separate systems. You may need to reprogram the key fob, (If that's what you meant by "keyless") but that can only be done by dealer on that vehicle. If the passlock gives you problems, you can bypass that.
