Ignition key copying

[Karl]

The key copier guy told me there is a chip in my key (VATS) and I need a chipped key to replace

Are the keys specific to the LT5 or will any blank key off eBay work

Thank you.

There is like 14 different resistor chips , most dealers have the reader to get you the correct key , you can get it cut anywhere !

Use and Ohm meter and measure the resistance of the black pellet.

1 in 15 chance that it will work. you need to determine resistor chip value from your old key.

Use and Ohm meter and measure the resistance of the black pellet (resistance from one side of key to other across black pellet).

Take the key that works by a GM dealer and ask them to "DROP IT' in their VATS Interrogator. That will ID the resistance code.

Last year I paid $35 at
the local Chevy stealership
for one. Took them 5 minutes
to make it.
Could be lots worse, $325 and a lot of
BS (proof of ownership etc) for a replacement
key at the local Teutonic car emporium ☹️

ACE hardware has a chip reader in their key dept. They read my key & sold me spares that work perfectly.

Hi all, I tried copying my ignition key about a year ago as I only received one when I bought the car.

I determined resistor value from my old key and ordered a replacement online and got the key cut. Car fired up perfectly and drove it about 20 mins then turned off the car. Came back a few mins later, key in ignition but no start. Seemed to be a VATS issue from what I read so I left the car about 20 mins. Tried with my old key and it started fine.

Has this happened to anybody else? I have refused to use the copied key in case this happens again.

I bypassed my pellet by adding the correct resistance resistors to the wiring under the column. Made a few keys as spares. But as suggested just need to find out the resistance And order the correct key.
