Pass key light

I just put in new steering column in 95 buick roadmaster. Everything went great, except I can't get it to start. It has power. The pass key light is on... what does that mean? Will it not start because it's a different chip in the key or what? How can I fix it?

That's exactly why it won't start. You can either switch the ingition lock back to the original one so you can use the right key. Or, you can sync the new key with the computer. To do this you or someone else will have to use a gm tech-2 scanner, snap-on modis or an otc genisys scanner. Your local dealer or good repair shop should be able to fix you up. Now, there is another way. The passkey system works on resistance from the chip. In you steering colum there is a 2-wire plug going to the ignition lock. If you pull it out of the colum and cut the plug off. You can pop the chip out of the original key and solder the wires to it. Just make sure you don't heat the chip up to much. After doing this you can use any $10 standard gm ignition lock instead of the expensive ones that use a chipped key.

Security fuse 1999 pontiac bonneville

Need a little more info . Security fuse ????? Do you mean anti-theft ? The SECURITY light is lit on the instrument cluster ? Content theft or vehicle theft ?
Vehicle Theft Deterrent (VTD) Description
Ignition Key
The ignition key for vehicles which are equipped with the PASS-Key® II system consists of the following components:
• A typical square ignition key blank
• A resistor pellet
The PASS-Key® II ignition key has the same mechanical key cuts as a non-PASS-Key® II ignition key. You can not service the key blank and resistor pellet separately. There are 15 different ignition key assemblies, each with a different key pellet resistance value.
When you service the PASS-Key® II system, obtain all ignition keys. Verify the proper key code values withJ 35628-A Interrogator.
Steering Column (Ignition) Lock Cylinder
The steering column (ignition) lock cylinder that is used with the PASS-Key® II system contains a set of electrical terminals. The terminals are used to contact the resistor in the ignition key.
The wire routing for the contacts inside the steering column is very critical. When you service the lock cylinder, maintain proper wire routing.
When you replace a steering column lock cylinder, make new keys. The new keys must match the following items:
• The PASS-Key® II code of the PASS-Key® II system
• The mechanical cut of the new steering column (ignition) lock cylinder.

Measure the resistance of the pellet on the key , go to radio shack an buy a resistor of same value an solder into wiring harness .

pulling fuse won't work , power's the PCM as well . Plus software in the PCM won't let it start if it doesn't see input signal from the Theft deterrent module .Take an get it fix right .

I needed a new pass key for my 1995 buick roadmaster, and i got that but i noticed that the little computer chip is lose,so when i got ready to use the key i got the same problem car not starting....

First off when you had the new key cut did the use a tester to find the number of the chip in the original key, if the numbers don't match it will not start.If you did not have a key they would have to hook up the tester to the car to read the number programed in to the pass key module..With all that correct GM has had many many issues with the ignition cylinder ( not the ignition switch which mounts down on the steering coloum) .On GM cars their are two very fine wires (orange) going from the cylinder to the module one of these wires often break the same tester that checks the key number also checks this issue but without it all you can do is a visual inspection of the cylinder the wire brakes right at the cylinder I know it sounds like a lot but without the special testing equipment the the dealer has these are not easy to diagnosis... Good Luck

Passkey light in the dash flashes and the car wont start on a 95 buick roadmaster

pull the fuse from the fuse panel on the left side of the dash. It can be accesed by opening the drivers door and removing the panel that is the left end of the dash. Pulling and reinserting the fuse will usually solve this problem. The other issue could be in the key itself. The pass key is simply a resistor built into your GM key.

Pass key stays on1995 buick roadmaster car want crank

Short circuit probably not the problem. The pass key system is not being disabled making the car inoperable, thats why it will not crank. Either you are using a key that does not have the correct resistance(black chip in key) or if it is the same key you always used then the pass key sensor went bad. I believe it is in the steering column and a qualified mechanic could help you there.
