Verifying Correct Key Code
WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This procedure is to replace a lost or broken key when another correct key is available.
Lost or broken keys must be replaced with a key that has proper resistance value. To determine resistance value or code, insert key into Interrogator (J-35628-A) and read key code. Use key blank matching this key code and cut it to match original key.
