Question about 2003 Buick Rendezvous
Usually the flashing security light means the computer is not finding the right code in the key chip.
Is the key you are using programmed to the vehicle ?

On your Buick 94.
The problem is the ANTI THEFT SYSTEM..
If you have replaced the ignition switch.
If you are using a NEW KEY, the car won't start.
Because in the OLD KEY, is there a Resistence with a number of ohm's
The computer need the resistence to activate the the signals to operate the vehicle.
OK.. with the New Key and Old Key you can go to any Aloha Smith and they will remove the Chip from the Old Key to the New Key.
And the car must start and running.
But if you are using the Same Key that you have before the repair made.
I recomend to check the 2 Orange wires from the Ignition lock Cylinder to the steering column lower connectors.
Ok I hope this work for your problem.
Any moree info, I will glad to help you.
I'm a Mechanic and have all the repair information for all the cars.
Thank you for use fixya...

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

Pass key is the security system which disables the car if it is stolen. You need the remote or a key with a chip to start the car. go to a dealer, prove ownership with registration and they will be able to help you out

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
