Passlock 101

You may possibly have the Ign. wires on the remote start hooked up to the wrong ign wires on the vehicle. 3) If the remote starter doesent work without the key, then you have the bypass box hooked up wrong or may not even be hooked up at all.

Thank you for replying! It is a 2004 chevy express van and the car does start and seems to work just fine but the security light comes on when I remote start and when I key start. Also the remote seems to work great most of the time but every once and a while it will not work untill I get within about ten feet of the vehicle?

Thank you in advance for any input!

Check the facts and try again!

I agree, using a quality bypass will eliminate alot of the problems. Also knowing how to integrate into the system correctly will eliminate the light from staying on.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

I will check over the week end and let you know but those seem like what I used ? The bypass I used is a 555l and the starter is a boa. Thank you for the quick responce!Check the facts and try again!

Great then you guys can help! If you search "passlock" on this forum you'll find an incredible amount of posts. Some if not most of these guys are using DEI modules. What are these guys doing wrong? Whats a common fix? Whats the difference between the Passlock systems. And how do you test for passlock wires? I talked to a guy dealing with a cavalier. Ignition isn't on the column and stuff... You have like 2 or 3 yellow wires how do you know which one is it? Why is it that sometimes the security light comes on only when remote started... or only when you start it with a key? I know we have some very knowledgable people here. But most important of all we have a combined experiance. If we can all share our experiances with Passlock we can learn from eachother. Tell the Snap-On guy I'm not here!

Ok, the first and major problem is that people don't solder there wires and they use a crappy ground, or don't solder the ground to the passlock ground. That is the number one problem, INSTALLER ERROR!!! To tell which wire the Rcode wire is, just use your meter. The wire will change voltage when cranking, not just to around 11-10 because the car is starting but more drastic. Again if the security light is turning on then the installer didn't hook the passlock bypass up correctly.Certified Security Specialist

well...to start things off, i've had no probs with a GM passlock system...i find them better then fords or dodge bypass modules, i use the plxr module and i've had no probs what so ever (unless i hit the program button after it's program'd and the key wasn't turnd...but that's my fault)  but personally, i'll put a remote start in a chev long befor a dodge remote start.

I usually don't have any trouble with passlock myself. But the thing is lots of people call me for installation help and 99% of the time it's a passlock issue. I would be saying how simple passlock is to work with too; but there have been times when I've done everything right and still ran into a dead end. Tell the Snap-On guy I'm not here!

I tried to use a PASS23 on a 2003 blazer...module blinked 4 times like it learned the code or whatever, but still didn't stay cranked. So I did the ol' school Omega bypass which is basically a VATS-type bypass once you learn the resistance value with the key on. Although it remote starts successfully, I still get a security light during remote start and after the driver inserts the key. But if you start it with key and not remote start, then no security light. I drove the car on the freeway about 5 miles after a remote start to see if the security light would cause any performance issues, but it didn't. So I just told the owner that the light would be on b/c the car wasn't started with the key, but it didn't hamper operation/performance of the vehicle. I now have a IBGMBP module that i'll try on the next GM passlock vehicle I get. I don't know about this PASS23...i was told it was supposed to replace the PLDATA2004 modules and what not, but now I see where it is for "some GM Passlock vehicles".

i have done well over onehundred vehicles with passlock II and not once have i had a security light stay on. i only use two different bypasses. the audiovox as-gm4 and a dei 555l. i work at a gm dealer and almost never ahve a car in service for a passlock issue. the passlock system is not usually to blame. as stated earlier by auxe installer error!
