Diagnostic Aids

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.

When using the J 43241 Keyless Entry Tester, first inspect the keyless entry transmitter part number to determine that it is the correct model for the vehicle. See Special Tools . An incorrect part number transmitter may pass the test, but it will not activate the keyless entry system.
When the vehicle key is in the ignition, the keyless entry functions are disabled from the keyless entry transmitter.
