94 z28 got a ? HELP :/
 

ok so my vats has locked me out of my car was starting fine running fine took my key to chevy dealership they said my key was bad. so i paid 28 bucks got new one put it in vats still locking me out. im no good on cutting wires & so on to do a vats bypass idk what to do >>> i seen this you plug in & it bypasses it will it work. guys need all info can get my car down

Re: 94 z28 got a ? HELP :/
 

If you know code 3 is the right one and you also know that this is really what your problem is, then it would work (but just as well as a less than a dollar resistor from Radio Shack). You don't have to cut wires to try a resistor.

Re: 94 z28 got a ? HELP :/
 

yea its code 3 they ran my vin to get it my other key was dead couldn't even get it to come up on multimeter to test to get a vats code. its gotta be the key the car was running fine i cranked it pull it up on ramps changed my oil put key back in it was dead security light flashing. & i put new key in nothing the security just statys on car hear fule pump come on but nothing.

Re: 94 z28 got a ? HELP :/
 

So the new key from the dealer, started your car so you could get it on the ramps, to change your oil. Then wouldn't start your car afterwards?

If that is the scenario, I doubt it's the new keys fault. I would hope the new resister in that key, wouldn't go bad, that fast.

Re: 94 z28 got a ? HELP :/
 

no my old key was the one was in it when i drove it up the ramps to do my oil. then i went to start it nothing took my old key to chevy dealership said my old key was dead pretty much. so today i bought a new key went to start it nothing just security light stays on. can hear fuel pump kick on all lights come on but nothing when i turn the key.

Re: 94 z28 got a ? HELP :/
 

got another ? my old key was dead no way to match it as ive seen people do with a multimeter. but mine wouldn't read at all guy at chvey dealership said can match it with my vin? can he do that get right code to my car even though couldn't get a reading from my older key im just trying go over everything.

Re: 94 z28 got a ? HELP :/
 

Got a new key from where?

They might be able to get it from the VIN, but they should also have a tool called an "interrogator" that they (or a locksmith with it) can get it from the car. Of course, they would need the car there to do it.

Re: 94 z28 got a ? HELP :/
 

i got the new key from the chevy dealership put it in nothing but security light stays on & yea cars been in yard since sat :/ i went ahead and bought Vehicle Anti Theft System Vats Bypass Keycode 3 |

Re: 94 z28 got a ? HELP :/
 

just super weird to me car started fine i pulled it up on ramps did my oil put key in nothing but the security light flashing. next day took to chevy dealership got new key put it in nothing but security light stays on not flashing. i just find it super hard that its something big car ran fine i could tell key was going out had car few months has the security pop on few times so im taking key was going bad.

Re: 94 z28 got a ? HELP :/
 

I think this is probably the first time I have ever heard of a key going bad. The thing is, if that was the problem, then getting a new key should have fixed it. I would have done more testing to determine just what the problem is. The key cylinder is the most common problem. If so, your bypass module should fix it (if it is the right value).

Re: 94 z28 got a ? HELP :/
 

yea it may take 20 years but they do die after time the two silver bars just wear out & stop making contact is from what i was told. i mean key want read at all at dealership so i went bought multimeter tested it myself nothing would show up on the old key so i tested new key it came right up. i did other simple test as pop battery cables off wait 15mins & few others i just find it hard to believe something went out it could have but my system has me locked out so im prying bypass works.

Re: 94 z28 got a ? HELP :/
 

it will be here fri hoping for thur just praying it works like killing me seeing car just sit there one big ? i asked could they look up my key threw my vin if they couldn't get a reading off old key as most do when replacing the key i say cause what if they gave me wrong key code ? next step wait i guess with bypass & go from there.

Re: 94 z28 got a ? HELP :/
 

good new & very bad news good new part came bad its still not working im lost at this point when i put key in nothing the security light stays on can here pump cut on but nothing. i have no idea what to but at this point i dont have money to take it to shop ive went over most thing no idea.

Re: 94 z28 got a ? HELP :/
 

Perhaps the module is the wrong value or there is trouble elsewhere. Take a resistance reading of the bypass module and then take a resistance reading at the TDM connector back toward the bypass module.

Re: 94 z28 got a ? HELP :/
 

that's what i bought im feeling that as well a code or something is not reading right i went to dealership the say calls for code 3 key so i by code 3 bypass. do test it with a multimeter ? what setting do i put it on 20k? & so you saying test the bypass i just got in the mail ? & witch other part do i test the orange cord that plugs into system or the other end sorry no good with the right names of the cords.

Re: 94 z28 got a ? HELP :/
 

if i go buy a pack of resistors i really dont wanna cut wires if i got to i can & can i just twist tie them together sick them in plug to test crank it ? or bad idea. also if my main key the very 1st key that went out will not pick up what key code i need was dealership right by looking it up on by my vin ? cause ive seen people on videos say once you do a vats bypass code keys don't matter?

Re: 94 z28 got a ? HELP :/
 

The bottom diagram in Shoebox's instructions show you that you do not have to cut any wires, just push the ends of the resistor into the harness connector:

This shows you the values you need to try:

4th Gen LT1 F-body Tech Articles

When you buy resistors, you need to connect them in series (end to end) to achieve a resistance within the range of low and high.

You seemed a bit confused about setting your ohm meter. You select the scale that will measure the resistor you are testing. Use the 20K (20,000 ohms max) range for resistors 9 thru 15. Use a lower scale for resistors 1 thru 8. Just make sure that the scale is higher than the resistor you are testing. You can't use a 2K (2,000 ohms max) scale to measure resistor #8. If that is the next scale on your meter below 20K, leave it on 20K for #8.

Re: 94 z28 got a ? HELP :/
 

All this info was available to you in the beginning. IMHO, I would have done some testing or trial with resistors for a couple bucks, before spending $20 on something that I was skeptical of. My first post said you don't have to cut wires.

I said before that I don't know if they really can get a key code from the VIN, but I believe that people that have lost their keys have provided their VIN and proof of ownership to a dealer to get new keys. So, it would seem legit.

Did you test the module to see if it is the resistance you requested?

Re: 94 z28 got a ? HELP :/
 

ok i tested my key got from dealership on 20k setting on multimeter it shows 0.66 & i just tested the code 3 bypass i just got in mail today it shows 0.66 matching the key. ok then i tested the cord you unhook the one that orange cord plugs into it comes up 7.2 something they didnt have my old key to go by cause it will not read at all just tried it 5times. instead of a code 3 would it be 13 cause of the other cord i tested tested under the dash? see if my old key would read i could bypass this headache.

Re: 94 z28 got a ? HELP :/
 

& sorry if it seems like im missing yalls info im not just so ill & bad storms coming trying get it done. but i have no way to know what code i started with cause my keys dead so i stuck multimeter to the end that the orange cord goes into & it showed 7.2 something witch on code chart is code 13 not 3.

Re: 94 z28 got a ? HELP :/
 

is there anyway to test for the old key reading other than the key ? cause code 3 aint working.

Re: 94 z28 got a ? HELP :/
 

a video if need one of me plugging it up into car trying to start write ill try beat the weather.

Re: 94 z28 got a ? HELP :/
 

You have a 660 ohm key and bypass module (based on your video).

Clarify which way you were taking the reading on the wiring...
The side with the orange sleeve is toward the key cylinder. If you take a reading there, do it with the key inserted (like detailed in the diagram in post #17). Reading should be the same as the key.
The opposite side of the connection is to the TDM. There is really nothing to read there, unless you want to take the connector off at the TDM and prove continuity to there. I suggested before to take a reading from the TDM connector back toward the bypass module to prove that is good. You need to know if that resistance reading is getting to the TDM.


The interrogator that I mentioned before is the only other way to determine the key resistance that I know of.

Re: 94 z28 got a ? HELP :/
 

gottttttttttttttttttttt it the stupid dealership gave me wrong key as i thought i went & got a shop to make the 1-15 code with resistors yes seem like a lot but it worked i went 1 by 1 & bam she fired up. :)

Re: 94 z28 got a ? HELP :/
 

i do got 1 more ? it was a 3.85 resistor ok that comes out to a code 10 key ok but my code 3 key worked as well as code 10 key but since the 3.85 code if i get the code 10 bypass just like one i got in mail today it will work ?

Re: 94 z28 got a ? HELP :/
 

Can you rewrite this, so I might be able to understand what you are saying?

Re: 94 z28 got a ? HELP :/
 

lol yea was typing fast hope yall safe its super bad weather here in nc >> said i got one more ? when i put the resistor & it finally cranked my car it was the 3.85 one that code shows that its a code 10 key. but my code 3 key was cranking it ? so if i got by another bypass since it was the 3.85 resistor that cranked it would it be right to by the code 10 bypass since my code 3 bypass didnt work.

Re: 94 z28 got a ? HELP :/
 

I don't know why you would have two different resistances working at this point. Not sure I would buy anything more until only one worked every time.

Re: 94 z28 got a ? HELP :/
 

that's what im saying im taking the dealership gave me wrong code when i tried the code 3 key & bypass code 3 i bought nothing happened. so i went to that 1-15 code chart took it to a shop got them to make me all 15 of the resistors to test the one that cranked it was a 3.85 one that pairs with with a code 10. so because the 3.85 one worked does that mean my key is a code 10 instead of a code 3 that the dealership said? if so ill just by another bypass but instead of a 3 code ill get a 10 code bypass? also i got them to make me a code 10 key free. i tried it 4 times b4 the weather hit cranked fine.

Re: 94 z28 got a ? HELP :/
 

The confusion stems from the fact that you claim it will crank with the #10 resistor, and also cranked with the #3 key the dealer sold you. Go back and read your post #27. That's what you said. It should not be possible for two different resistances to allow the starter to crank the engine. That's why Rob posted his response.

Re: 94 z28 got a ? HELP :/
 

ok here we go i had the code 3 key in it when it cranked up, ok but the resistor value when it started up was 3.85 witch goes with a code 10 even tho had code 3 key cranking it but when i had the code 3 bypass & the matching code 3 key it would not start? but i read once you do a resistor bypass & it kicks the car over you dont need a coded key ??? heard some1 say that in a bypass video? but i tried 1-15 resistors on that chart the 3.85 was only one to start it up ? witch comes up to a code 10.

Re: 94 z28 got a ? HELP :/
 

IDK, but that sentence (such as it is) maybe makes sense only to you. :confused:

Re: 94 z28 got a ? HELP :/
 

ill just shoot a video tomorrow make it easier.

Re: 94 z28 got a ? HELP :/
 

Reminder.... I can read your posts even after you delete them. No need to get mad because we can't understand your sentences. We are trying to help, but we cannot help if we can't understand your version of the English language. As I recall, we have gone through this before, and when you went into one of your rants, I simply stopped helping you, because I didn't appreciate what you had to say about me.

Here we go again.

Re: 94 z28 got a ? HELP :/
 

what are you talking about ???? that comment i deleted i had a lot more in it but for some reason when i posted it all my message didnt go threw so i just took it off, so b4 you think you know what i said ask cause i just didnt want to retype it all & no you jumped all over me in the past for no reason & sorry i wasn't raised to be punk & not to speak up sorry, but the post that i took off i was not being smart & i speak fine if anyone does no want to help me that's fine stay off my post ive thanked everyone that has helped me even you but for some weird reason you got a problem with me or what i post not sure.

Re: 94 z28 got a ? HELP :/
 

All I am asking is that you present your thoughts more clearly and with non-run-on sentence structure and punctuation. It only enhances your chances of getting help.

so its ok for you to talk to me anyway you want? but i cant speak up. you can private message me as well i don't even know how to send one? because your a Moderator doesn't give you the right to try & talk to people anyway you want, so take it how you want to. did i ask you to come on to my post ? like i dont get your problem at all. ive been nothing but cool to everyone but you just take a CAR WEBSITE WAYY TO FAR. its suppose be fun guys asking questions about their cars not someone trying to put people down.

Re: 94 z28 got a ? HELP :/
 

im over it tho Injuneer i have not one bit of hard feelings for you or the things you say or may not mean to say. shoebox you as well, all i was trying to do is get my car running witch i have. good luck guys.
