The toggling of the horn chirp (between enabled and disabled) can be performed with the use of the scan tool or by the customer.When using the scan tool, select:“TIPM”“Miscellaneous Functions”and then the desired function.Using a transmitter programmed to the Sentry Key Remote Entry Module, the status of the horn chirp may be toggled by the customer.The SKREEM is responsible for keeping track of the horn chirp status; thus this procedure does not need to be repeated for each transmitter programmed to the system.With the ignition switch in RUN position, press and hold the transmitter UNLOCK button for a minimum of 4 seconds to a maximum of 10 seconds.While holding the UNLOCK button for 4-10 seconds, press the LOCK button. A chime will be heard to indicate a successful toggle, at which time both buttons may be released.
