PostPosted: Sun May 29, 2011 5:56 pm    Post subject:  PassLock Security Light Bypass Reply with quote

My 2002 Impala left my daughter stranded three times with a flashing Security light in the last month. I did some research and decided that the resistor bypass was the most reliable and inexpensive solution.

It took me about two hours to take apart the dash and carefully double check everything I did, and take pictures. If I did it again... maybe 45-60 minutes (plus getting resistors).
I was lucky to have some resistors close to what I needed, so it cost me nothing but some time.

Here's what what I did:
Remove the dash to get to the ignition switch. I have more pictures, but I'm pretty sure there is a write-up to take the dash apart.
Here's one: http://impalahq.naioa.com/HowTo/Dash.html
Remove the two bolts from the switch, and pull it down so you can get to the wires.

Find the three wire bundle coming from the key-end of the switch. They are small white, yellow, and black wires. Other people say don't cut the white or black. I cut all three, so I could unwind them from the other wires. Also, cutting and reconnecting the black wire is much easier than stripping the insulation with a freaking exacto blade. (anyway, it's OK to cut all three for your convenience)

Reconnect the white to white and black to black.
Connect your Ohm meter to the key end of the cut yellow wire and the reconnected black wire.
Turn the key to on. Step on brake and put the shifter in reverse, so it won't start.
Turn the key to Start and release to On, and check your ohm reading. Try it a few times to verify the reading.
My "key" resistance checked at 1230 ohms and up to 1350 ohms.

I happened to have three resistors totaling about 1390 ohms. (At least according to my $10 meter).

I connected my string of resistors to the yellow wire from the wiring harness and the other to the reconnected black wire.

I put the car back in park and tried to start it. It started.
I tried it several times to make sure. But we also have to remember that this problem was very rare and random.

I finished trimming the wires and soldering the connections.
It still started OK.
I taped up all the connections. (I will not show pictures of that.... Not too proud)
It still started.

For fun, I diconnected the battery for a few minutes (while I check the oil, topped off the washer fluid, etc.). Reconnected the battery and started OK.

I'll keep my fingers crossed, and we see it lasts. According to everything I read, it should be OK, unless there is an issue with the BCM, BCM connections, or the wiring from the resistor to the BCM.

I hope this helps anyone else having PassLock problems.

And here is a picture of the best and fastest soldering "gun" in the world:


The best source of information I could find was:
http://www.bergerweb.net/grandamsecurityfix.htm
There is lots of good information there.

I took a quick look at the BCM to see if I could make the bypass there, and avoid digging into the dash. The BCM is under the dash, just left of the steering column. I unplugged the center plug, but it didn't seem to match the Grand Am BCM. It was easier working at the switch, instead of under the dash, anyway.

The bypass is still working fine. I haven't had a problem in almost a year.

Wow. If only I had known to do this when I was bashing my head into the steering wheel waiting out the 10 minutes of leaving the key in the on position to get it to start. This should be in the FAQ section for sure.

Thanks for the reply.
There's been a lot of views on this, and I been dieing to know if it helped anyone take the plunge... or if it scared everyone away.

Then again, This car is 10 years old. It's getting close to the time to let it go...

when i was looking for awnser on this, i couldnt find this link...... nor did anyone link it lol i was getting the light 1-3 times a day!
when i got my overkill tune i also got him to disable that, never had a issue since

I did this exact 'mod' on my SS. I wasn't really having a problem, but I was installing my viper alarm/remote start and this saved me from having to get the security bypass for the remote start to work. It was a cheap(free really) mod and has held up for 2 years now.

Great write up btw.

Thank you for taking the time to post this! This is good stuff. However, I believe I took the "lazy man's" way out. I avoided soldering by buying a terminal strip and resistor at Radio Shack and building a little circuit bridge.

I hope I can post this link. I take no credit, but good stuff as well!:
http://www.bergerweb.net/PasslockFix/

Why measure the resistance of your "old" reading, when the BCM can recalibrate itself to a "new" (reliable) resistance? I did the relearn trick, and it took 3 times, (which was a bit unnerving), but it popped off on the fourth try.

Buh-Bye issues. Total cost, $11.53. (Yeah, I mail ordered... I don't like going to Radio Shack. I find their in store service around here lacking.)

We can disable it using a tuner? Why didnt i know about this? lls How do i do it? I have a dhp tuner.

I would email overkill as he did this for me.

Here's a slightly easier way.

Once the ignition switch is dismounted, you can just turn the key, press in the lock for the key cylinder, pull it out of the starter switch, and then remove the Passlock connector from the starter switch. Then just push the lock cylinder back in.

The Passlock connector has female terminals, so you can just plug in your resistors directly into it.

100% reversible, no cutting, splicing or soldering (besides soldering the resistors together)! Very Happy

I was having the no start issue once a day and tried this and havenít had the problem in over a month. The hardest part was getting that d*** bracket off under the steering wheel. Thank You ZeeVert!!!

...

You are correct. Quite frankly, I was nervous about changing the resistance and decided to try and match the original resistance.

I've reached a year and a half with this fix, and no issues.
My Impala has over 160,000 miles, and it's all cleaned up and ready to sell.

So installing a remote starter on the car, would also 'fix' the problem?
