It is all going to depend on what wires they cut or messed with. i would not reccomend taking it to the dealer, i suggest getting a wiring diagram ALL DATA has a good one time user program that would give a good diagram or ideal on where to start with the wires, note that they may have burned some wires up or shorted something out.

SOURCE: Need to see diagrams of the figs. 3-6 from a Chilton's manual...

My son came down and figured it out for me. Not sure what all he did but he had to make a few modifications by splicing the wires together after cutting the wires just under the dimmer switch...then a few adjustments were needed to get it to all work right.

SOURCE: need to bypass triad security system - car wont start

There are several configurations of the same security system. But one sure fire way to correct this issue is to get a bypass kit. Any shop that installs remote startups has the ability to bypass this system. Since the sytem measures the resitance of the key/lock and asociated wiring any shorting of those wires will make it very difficult to defaet without some expertise.

Sometimes the remote atart kit also includes the bypass, so you can get two for one here.

Good luck

How to bypass security system in my 2000 Pontiac Bonneville SSE supercharged

Hi the Bonneville most probably has the chip in the key ( GM calls this the vats system) this can be easily tricked by doing this. First u have to know the resistance on the key pellet get a meter and put one lead on each side of the little silver pellet on your key , set your meter on resistance, you will need to know this resistance , (note ) if u have a extra key you can just solder a wire to each side of the key again on the pellet and use this in the next step.
now if you don't have a key take the resistance readings to radio shack and get a resistor that matches close to the resistance readings you got from the key., NOW go under the dash of the car, look at the under side of the steering column for a orange wire (actually its two wires in an orange cover , cut this orange wire , split these wires and strip them . now solder the resistor on the car side of the two white wires in the orange cover, is doesn't matter which wires go where , if you are using the old key method wire the key to these wires basically you are looping the system to believing there is a resistor key in the ignition do not wire anything to the side going up to the steering wheel area these can just stay cut they have nothing going to them after u cut the wires , after the resistor is soldered into the car side of the harness the car should start and u can have regular keys cut

My mother has a 93 Pontiac Bonneville that will not start. It turns over, however there is an indicaiton on the dash board that says Anti-theft Device. How can we bypass this or get it to started?

Replace the ign lock cylinder. Or get new cylinder and plug it into the connector from the old lock cylinder at the lower part of steering column. Put old chip key in the new cylinder and hide under dash. Start car with a duplicate key from old key. No need to tear apart steering column ever again for this problem.

I have a 1998 pontiac bonneville. the cars security light is on and the car wont start.

I have the same car, had the same problem. If you know a little about the car heres a cheap fix. The problem is the key reader (i don't know the name of it) take off the panel below the steering wheel, look for a pink wire coming out of steering column cut it in half (careful yellow is air bag). Then take an ohms reader($20.00 @radio shack) read the resistance on the security piece on the key (little black piece) buy a pack of resistors from radio shack ($6.00) and piece together the same resistance that is on the key. I think you get a 10 or 20% variable so it does not have to be perfect. Mine was 1.83k. inside the pink wire is two white wires split them and loop around the resistance wire you made. use the wire coming from the toward the engine, not the one going toward the key. The car should start.And that gives the system a proper read.

Security light won allow startup

sounds like the 2 wires on the lock cyl are broken you have to remove steering wheel, lock plate and turn signal switch to get to the lock cyl then the 2 wires run from the key lock cyl to under dash so you will have to run them into the steering column you do need special tools to replace the lock cyl

Can someone please tell me for sure where the neutral control switch is on my car and if it can be tested before replacing it -2000 pontiac bonneville

Its on the trans, where the shift cable attaches. To Test it, have someone hold the key to the start position, and test if you have power to the switch. It should go in and out, usually the wire going OUT to the stater is PURPLE. Try to start the car in "N" and see if it then will crank. If you have power to the PURPLE wire , but the car doesnt crank, rap on the starter with a hammer and see if that gets it going, if so, replace the starter.

Security light flashing, does not turn over, do i replace ignition or ecm or both? Do i need new key if i replace ignition?

Chances are the wire going to ignition broke allowing the security to start flashing.this will keep the
car from cranking.On my 93 bonneville I went to Radioshack and got a 680 ohm resister,cut the 2 small
yellow wires on lower steering column under dash,soldered resister to the 2 yellow wires coming from harness.Cost of repair..$1. you can read the resistance on the key by using ohm meter on each
side of chip in key
