- For the J 43241Β Keyless Entry Tester, inspect the keyless entry transmitter part number to determine that it is the correct model for the vehicle. See Special ToolsΒ . A wrong model transmitter may pass the test, but it will not activate the vehicle remote system.
- The keyless entry transmitter used in the 2 Way Advanced Remote Start System is unique to the system. When servicing or replacing a transmitter, ensure that the correct transmitter is used. The correct transmitter part number can be found in the Accessory section of the parts catalog. Attempting to replace an 2 Way Advanced Remote Start transmitter with a regular service part may result in a failure to program the transmitter.
