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 had to replace the steering colum and switch how do i reprogram it. its a 05 ford escape the door key is a different key thin the one on the colum?


Your best bet is to remove the lock out of the old one and put it in the new one. First look at the keys, If they have a small square on the back end, this is where the chip sits. You can pry them out and swap them. This will start the truck. Otherwise it is a dealer or lock smith.

How can I by pass the pass key code on my 99 pontiac montana


If you try to use a blank key chip in a vehicle that is meant to use a key with a chip installed, the chances are excellent that your vehicle will not start. The computer chip in the key mates with a piece of program code in your car's computer system. When the two halves are there, your Pontiac will start easily, however, if you attempt to bypass the coded key, your van won't start. For most drivers, this is not an issue, unless an ignition key is lost. If you lose the key you will have to replace it with a matching one which will prove expensive. It can cost up to $85 or more to replace this type of key in some cars because the key has to be encoded to work with your van. Unless you know someone with a blank spare for the same vehicle who will give the key to you, as well as someone who can program the key, then you will have to pay the freight on a new key and encoding. If you would like further information on this and other automotive issues, please take a look at <a_href="www.safecar.info">www.safecar.info</a>.

My 2005 buick rendezvous has been attempted to be stolen cant start it with key


if they tried to pull the wheel lock located in the steering colum. they may have damaged the key sensor that read you security codes off the key. which means you`ll need to replace the key sensor in the colum. Unless they pulled a wire off under the steering colum. look down the steering colum and up underneath and see if there are any plugs out. PS some cars are designed of extra accessories which case you may find a few plugs away from the colum that aren`t connected to any thing these won`t be the issue but.

I have a 1999 Jeep Grand Cherokee. The vehicle


sounds like the key is either worn down to where the ridges in the key wont push the tumblers inside the key lock cylinder into their proper place to move the cylinder into the starting position. Or your steering colum is locked and the wheel is moving freely as if it were not. So your solution would be to either have an expert look at it (estimated cost: 200$ low/400$high) or you can attempt to fix it yourself.
should you choose the "I'll fix it myself" method....try getting a new key made at a hardware store since keys wearout over time (ie:10years of turning that old key), this may solve the problem right away if the ridges are just worn on the key. Or the hard way, you need to get a phillips screwdriver and some jewelers tools and an 8mm or 10mm wrench/rachet+socket to disconnect the battery, then underneath the steering colum just under the ignition is a hole in the colum shroud/cover, from there you can disconnect the ignition key lock cylinder (the thing you put your key into). once you've removed the cylinder from the steering colum you should test your key again to see if you can turn the cylinder outside of the colum if you cannot then buy a new ignition key lock cylinder for about 15$-30$...problems solved.

Getting message that reads key pass failure..whats it mean? anad is it something i can fix myself or does it requre certified technicians to reapir it? Please advise.. Thank You Kindly


pass key is an anti theft system that gm uses your ignition key has a resistor in it. It is possible that this has gone bad you can go to the dealer to have them check the key out. If you need a new one they're usally around $20.00. if it is the ignition it's self you can by pass it. there is an orange wire coming from your steering colum inside it is two wires if you know the resistance of the chip in your key you can solder a resister between those two wires. and that will by pass it

Pass key light


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.
