dam security light

measured my keypelet with multimeter reading was 9.55 is this right does this mean i need a resister of that value.

any feed back greatly appreciated thanks

 

you actually have VATS, passkey II is mostly in other GMs. if your resistor in your key read 9.55Kohms then yes you would have to get a resistor of that value and splice it in.

If you need anything else let me know.

These are the key values...9.55 is not there...probably 955 ohm's

GM No-Crank in vehicles with
Vehicle Anti-Theft System (VATS)
A No-Crank condition in GM vehicles with Vehicle Anti-Theft Systems may be caused by either a bad igintion key or a
problem in the ignition switch/VATS wiring harness. (Switch/harness assembly problems seem to be more common than
Test 1) Check the ignition key. Each key contains a resistance pellet. Remove the key and check the pellet’s resistance.
The chart below shows possible resistance values for ignition keys. If the key resistance matches one of the chart values,
go to Test 2. If the key’s resistance value doesn’t match one of the values in the chart, replace it with a new one. Your
GM dealer can provide part number information if you give him the VAT module identification number.
Test 2) Insert the ignition key in the ignition switch. Remove the lower dash bezel. Locate the two-terminal white connector
near the base of the steering column, and disconnect it. (See the next tip for a schematic.) Insert your ohmmeter
leads across the terminals of the connector half containing the white wires and measure the resistance. The resistance
value measured across the connector should match the key resistance. If it doesn’t, then the problem is in the switch/
harness assembly. Replace the assembly.

Experience suggests that VAT
ignition key failures are less
common than no-cranking conditions
caused by switch/harness
failures.
If you need to start a car to get it
into the shop, try this:
• Remove the ignition key and
measure the resistance of the pellet
• Drop the steering column bezel
and disconnect the white wire
connector.
Resistor Bypasses Ignition Key
• Connect your sensor simulator across the terminals of the harness connected to the VATS module and “dial in” a
resistance equal to the key pellet resistance, or simply insert a fixed resistor of the correct value.
This bypasses the key/harness and, in many instances, it will allow you to start the vehicle and drive it into the shop.

DL THE PDF for more info

 

thanks guys im doin this friday if any trouble ill bother yall thanks alot guys

 

Anyone have any info like that on the passkey II? My brother has a 98 Cutlass and he's having problems with the security system.

 

thanks guys i did the bypass and it work and knowing my luck i had another freakin problem starter

 

EDIT: DAMMIT I NEVER READ THROUGH, good to hear you got your problem solved.....before I made this post

stupid, stupid stupid...lol

955-ohms was mentioned, but 955-ohm isn't even within the values posted on the VATS ranges chart I would say it's probably a 9.55kohm reading, which would translate to 9530 ohms on the chart posted in the quote...This is a valid 1% resistor value; if it were me I wouldn't use anything but a 1% resistor for this application because the standard values for 5% and
10% are not close enough when the next-closest resistor is used and tolerances are considered. I suppose you could use two 5% resistors stacked (9.1Kohm and 430-ohm would give you the correct value and +- 5% would put it within the ranges, barely) but 10% will not work...Just save the trouble and make sure you get a 1%-tolerance resistor.

But 99tankta, my advice would be to take the reading again if you don't know the units. Just making sure you didn't buy the wrong resistor

 

FYI ... we DO have Passkey II ... PassKey II , VATS (vehicle anti-theft system) are the same thing.....

Passkey II uses a resistor in the key

 

whereas i understand what you are saying...passkey 2 and VAts are a little different to say the least. they are both resistance based....but not the same thing.

however both can be bypassed with just a resistor.
