Your key has a transponder in it and it needs to be programmed at a dealer. The on board computer is mated to the key and if you add a key, you must have all keys present and programmed at the same time. If you are close to a dealer you can give them the VIN number and they will be able to cut you a new key. Then if the shop foreman has time, he may come to your car and programme the key(s) for you. Other than that, you need to tow the car to a dealership. Hope this helps

2000 buick century security troubleshooting


Do you have the correct keys now? The dealership can cut the correct keys off of the VIN number if you have proof of ownership. Without the proper transponder in the key the security system will not allow the car to start.

How do I turn off the alarm on a 2000 buick century without a keyfob?


You can turn it off as long as you have the key. Just turn the ignition to "run" if that doesn't work start the car it should shut the alarm off within a few seconds.
I lost my fob and this worked for me.

I lost my transponder key for my 2000 Buick Century I have the ignition able to turn all the way start the engine but I need the resistance codes can I get them by attaching a meter to the two white


No you can't ,the resistance is in the pellet , not transponder , that's newer pass-key 3 .
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.
You need the key to measure the resistance !

The sensor on the key is not connecting i dont think do i need a new key or is it repairable in the house for a much cheaper price


The "correct" way to fix this is to replace your ignition lock cylinder.

With that said...

The system can be "bypassed" by measuring the resistance of the resistor pellet in the key and cutting the white wires coming down the steering column from the ignition switch and soldering a resistor of the same resistance to the wires.

I cant unlock my car with the remote or the key


The ignition key does NOT open the door lock on my 2004 Buick Century, but the Valet key does. I just thought that was how it was supposed to work.
