How do i get vehicle out of park?

Your Rendezvous has GM PasskeyIII

"When trying to start the vehicle if the engine does not
start and the SECURITY message comes on, the
key may have a damaged transponder. Turn the ignition off and try again."

So if the SECURITY is showing on message center then the key is not recognized and you will need to try a different transponder key.

If SECURITY is not showing, then set the emergency brake and move transmission selector to N(uetral), keep foot on brake and try to start.

Check engine light on ? Check for code's , Battery in good condition , connection's good , headlamps come on bright ? Instrument cluster light's come on ?

well it seams that Power disconnected, I mean do you have any security device kind of remote security device , it have power shut down from there for security reasons... so check it from there ...
best of luck if you have any further problem feel free to mail me .....my [email protected]

Sound like a SECURITY SYSTEM is armed; I suggest check in the Owners Manual to disarm...




When the PASS-Key III system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. The starter will not work and fuel will stop being delivered to the engine. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes.

When trying to start the vehicle if the engine does not start and the SECURITY light comes on, the key may have a damaged transponder. Turn the ignition off and try again.

If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty.

Hope this helps.

The steering wheel will not "lock" until you turn it about 45 degrees from center...this is normal. If your security light is flashing, there is a problem with your security system that is keeping you from starting the engine. Try this: Set the parking brake. Turn the ignition to the "RUN" position and wait about 10 minutes for the security light to stop flashing. When the light stops flashing, crank the engine without turning the key to the off position. If it starts, take the vehicle to get the security system checked. If it doesn't start, tow it. You probably need a new PassKey sensor.

If it is factory installed remote start lock the doors with the fab as you would to set the alarm then hold the start button at the top of the fab it should start.Please note that if the vehicle has a check engine light on the remote start function will be disabled and will not work.

The fab key activates the security system in the car, the ignition pass lock may need to be reset to your ignition key's. It Takes about 30 min to do. Try resetting the pass lock to read your ignition keys. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK. Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps. The ignition keys has a resistor value for the ignition to read and after a few years the resistance may change and the Pass Lock has a had time reading it's value so you have to reset the pass lock to read the keys again.

Any chance your vehicles have a security/alarm system. Disconnecting battery on some, will arm it sometimes & not allow it to run. Using key to unlock door, on driver & passenger side have been known to work on some vehicles, but if not, a call to dealer should help.

I had the same issue with my remote start on another vehicle, the part that bypasses the code on the key had to be reset. The way we figured it out was everything was normal except the vehicle did not start & the security light flashed rapidly.
