The horn chirp can be toggled using a DRB III® or by using a programmed Remote Keyless Entry (RKE) transmitter.
To DISABLE (cancelling) the horn chirp feature, press and hold the transmitter LOCK button for a minimum of five seconds. While pressing the LOCK button in, press the UNLOCK button. The horn chirp feature will not function until the above procedure is repeated.
