1995 Buick Park Ave Ultra Will not start

Your car has a system system known as VATS. If you do not have the correct value chip in the key, the car will not crank or start. Does the key you are using have a small black pellet in the blade of the key? It should have. If it is a key that used to work, there could be other problems. It is common for the wires that go from the plastic ears on the lock to break. There are more things that can be said, but the key question needs to be answered first.

That is really good advice, Dennis. I fought one of these for a year or two until I got fed up, and I bypassed the VATS system. Yes, some would repair them, but I was tired of the BS.

The precision resistor used to bypass the system cost less than a buck.

These GM models often have corroded internal connections on the battery cables. This is another thing to check, as well as the starter.

If the battery is down get it charged up or replaced. Does the anti theft or security light go out after key is on? Factory or add on alarm system? Chip in key system? If not turn key on for 15-20 minutes and see if it will go out and start. If no crank after battery is charged up jumper the started solenoid wire with 12 volt jumper and make sure the starter is working.
