Diagnostic Aids

WARNING: This page is about a different car, the 2009 GMC Envoy and 2009 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

For the J 43241  Keyless Entry Tester, inspect the keyless entry transmitter part number to determine that it is the correct model for the vehicle. See Special Tools . An incorrect transmitter may pass the test, but it will not activate the keyless entry system.
