IMO no, it just plugs into the connector under the steering colum right? You could just put a resistor in the connector matching your nominal key pelet value.

cool. can you explain what im looking for and how to or is there a sticky

I work for ecklers, and they do work, but if you have a soldering gun and a basic knowledge of electronics, you can make your own. If you screw up something that goes to the BCM, get ready for a hard fight.

since when does a resistor produce a 50hz sqaure wave 5 volt signal???

2001NBMZ28

The resistor just matches the nominal key pelet value to the BCM. People have been bypassing VATS with a resistor for years.

When you use them as supporting hardware for a 555 circuit.

good one

remember the middle eastern guy from the famaily guy that was in the office peter worked with and he was learning sarcasm? try to imagine that voice right now.....

thats funny because that 2001 nbm guy dont know what he talking bout and only you (six speed) and me get it

im still having trouble. keys read 9.53k so i bought 2 4.7k resistors and plugged them in. nothing happend. the security light stopped blinking but no crank

use a multimeter and get the exact resistance. you have to be very close. if you purchased ±20% resistors you might be far enough off for it not to read.


i believe if you do a search on google there is a site out there that gives you the exact bands that it will tolerate


it is always possible to retrain your car to accept another key combo.

i used a multimeter and it read 9.53K on both keys. how can i retrain it?

Well.

I think your value should be 9530 ohms and not 9.53K ohms. Try that first because retraining the car is very very annoying.

robster

that is what it is, so....what now

9.53K is 9530 ohms

robster

ok, heres what i just did. i took and unplugged the connector, put the key in and checked the wires from the key cylinder with the multimeter. i believe i should have gotten the same reading as the key, but i got nothing. does this confirm a broken wire in the column area?

From the GM service manual for his vehicle

Body Control Module (BCM) Programming/RPO Configuration


Important
Any new BCM will automatically program to the resistance of the ignition key being used at the first ignition ON cycle. This can only be done once for the life of the module.
The BCM can only be programmed to one ignition key resistance. All ignition key resistances must match.

A new BCM is not programmed. Before the system will function properly it must be programmed to the code that matches the customer's keys.

Insert one of the customer's keys into the ignition cylinder and turn it to the ON position. Start the engine at this time in order to verify system operation.
Observe the SECURITY indicator lamp for the following conditions:

The indicator lamp lights steadily for approximately 5 seconds and then goes out. This indicates that the BCM is programmed properly.
The indicator lamp flashes at a rate of one flash per second until the ignition is turned OFF. This indicates that the BCM did not program and the system should be checked for a fault.

It looks like it will not learn a new key value

dang. im pretty sure theres a broken wire in the column or ignition switch

robster

i fixed it. thanks guys
