NEW GM CHEVY CORVETTE VATS Ignition Key #14 UNCUT V.A.T.S 598524

Description: 598524FACTORY ORIGINAL CHEVY BOWTIE LOGO KEY DOUBLE SIDED VATS IGNITION KEY BLANK #14 V.A.T.S OHMS: #14 = 9.530FIT 1997-2004 CHEVY CORVETTE ATTENTION: EACH CAR CAN HAVE 14 DIFFERENT KEY VALUES (VATS)WRONG KEY VALUE WILL NOT START THE CAR THIS IS NEW BLANK KEY (UNCUT)NO PROGRAMMING NEEDED Not sure which value you need? If you have a meter with an Ohms setting, set it on 2OK and place one lead on one side of the pellet and one lead on the other. A value will be shown. Use the chart below to determine which number you need.If your Ohms value does not match the charts number exactly, round it to the nearest number. Example: Your key measures 1.18O Ohms. The blank you most likely need is the number 5 key as it is closer to 1.13O Ohms, than O.887 (4) or 1.47O (6) Ohms.

Hopefully, this will help elevatesome of that. VATS stands for Vehicle Anti-Theft System. It is commonly referred to as PassKey.Later versions include PassKeyII, PassKeyIII and PassLock (which uses no resistor "pellet"). GMfirst introduced VATS in 1985 on the Chevrolet Corvette, and after proving successful, was laterintroduced in other models in later years. Lets break it down even further: Operation: Operation is fairly simple, but lets discuss what all makes up the PassKey system.The most obvious part is the key. The ignition key as a little "chip" in it. This is a resistor"pellet". There are 15 possible resistances, therefore 15 different types of keys each with adifferent resistance. This reduces the likelihood of a potential thief from having the correctresistance resistor on hand. Then you have to have a special lock cylinder to "read" the key. Iuse the term "read" loosely, because it does anything but read the key. I will explain more later.Next is the VATS module. It does most of the security work. It is the "brains" of the system.The module is what actually "reads" the resistance, but has to do it via the contacts in the lockcylinder and the related wiring. Think of the module as a Multimeter, and the wires and contactsthe Multimeter Leads. The module reads the resistance and determines if the resistance is thecorrect value. The module will go into several modes, depending on what the module sees. Thereis "Tamper" "Normal" and "Fail Enable". Normal: Normal is when the correct resistance is seen during cranking and the module will groundthe Start enable relay, and send a "Fuel Enable" signal to the ECM. This basically "turns on" theinjectors. If the Fuel Enable signal is lost or not sent, the injectors will never pulse. The signal is aunique "Pulse Width Modulated" signal, which is a series of rapidly switched "on" and "off"voltages that would be near impossible to duplicate. Once the relay is grounded, voltage is allowedto the "S" terminal of the starter, and the ECM is told to pulse the injectors and the car starts. Tamper: This mode happens when the vehicle is cranked, and the resistance value as seen by themodule is not the same as the value stored in the module. When this happens, the module shutsdown for 4 minutes. Even if the correct resistance is then seen, the car will not start for the 4minute "time-out". The security light will also illuminate for the 4 minutes. The Start EnableRelay will not energize and the Fuel Enable signal will not be sent. HINT: if the key pellet is dirty,it will put the module in the "Tamper" mode. If your car fails to crank/start and the security lightcomes on, try cleaning the pellet, wait 4 minutes, and try again. Fail Enable: This mode is to help keep the motorist with the right key from being stranded. If afailure happens to the PassKey system AFTER a valid start, this mode is initiated. It allows thevehicle to be restarted, even with a failure present. The security light will remain illuminated to letyou know a failure is present. However, this also means that the car can be started w/o a key, andis vulnerable to potential thieves. Lets take a look at the basic setup. Diagnosis: If your car doesn't want to crank and the security light comes on, here are a few things that mayhopefully get you back on the road: First, make sure the pellet is clean. A dirty pellet will give a higher resistance than what the VATSmodule expects to see, and assumes it is the wrong key. Check all of your fuses. If a fuse is blown or missing, it can cause a security problem. Obtain a multimeter and measure the resistance of the key. Then remove the hush panel on the drivesside of the dash and find the wires that go to the lock cylinder (usually two thin white wires, sometimeswith orange insulation around both). Now measure the resistance at the two wires with the key in theignition. If it doesn't come within a few Ohms of the original key resistance, the lock cylinder is bad. If the resistance comes up OK, measure it again, this time while moving the key from "Off" to "crank"several times. Any fluctuation in resistance means a bad lock cylinder. This is the most common causeof failure. The wire are anchored to the stationary steering column, but attached to a rotating lockcylinder and over time, the wire breaks inside the insulation and usually becomes "open" in the crankposition. This is read by the module as an incorrect resistance. These are the basics of VATS diagnostics. If the problem is not found, it will have to be taken to areputable repair facility.
