I just bought this Colorado and it does not have keyless fobs and I would like to have remote do0r lock function to work but am not sure if wiring is installed.<\/p>\n<hr \/>\n<h4>The keyless entry system<\/h4>\n<p>The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock\/unlock the doors when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the body control module (BCM). The BCM interprets the signal and activates the requested function. A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:<\/p>\n<ul>\n<li>Door locks<\/li>\n<li>Vehicle locator\/panic alarm<\/li>\n<li>Illuminated entry lamps<\/li>\n<\/ul>\n<p>The keyless entry system has the following components:<\/p>\n<ul>\n<li>Keyless entry transmitters<\/li>\n<li>BCM<\/li>\n<li>RF antenna<\/li>\n<\/ul>\n<h5>Keyless Entry Transmitters<\/h5>\n<p>The keyless entry transmitters are used to lock and unlock the vehicle door while away from the immediate are of the vehicle. Transmitters will operate at a distance of up to 20\u2009m (65\u2009feet), except Japanese and South Korean vehicles, which are limited to 4\u2009m (13\u2009feet). Up to 4 transmitters may be programmed to a single vehicle.<\/p>\n<h5>Body Control Module (BCM)<\/h5>\n<p>The BCM is a multifunction module that operates both the keyless entry system. When an RF message is received from a keyless entry transmitter, the BCM interprets this signal performs the specific function, i.e. door lock, door unlock, or vehicle locate.<\/p>\n<h5>RF Antenna<\/h5>\n<p>The RF antenna receives RF signals from the keyless entry transmitters and tire pressure monitor sensors. The antenna is basically a length of coax wire with the outer shield casing partially removed that is connected directly to the BCM.<\/p>\n<h5>Unlock Driver Door Only<\/h5>\n<p>Momentarily press the transmitter UNLOCK button in order to perform the following functions:<\/p>\n<ul>\n<li>Unlock only the driver door<\/li>\n<li>Illuminate the interior lamps for a determined length of time, or until the ignition is turned ON<\/li>\n<li>Flash the exterior lights, if enabled through personalization<\/li>\n<li>Disarm the content theft deterrent (CTD) system, if equipped<\/li>\n<li>Deactivate the CTD system when in the alarm mode<\/li>\n<\/ul>\n<h5>Unlock All Doors \u2013 Second Operation<\/h5>\n<p>Momentarily press the transmitter UNLOCK button a second time, within 5\u2009seconds of the first press, to perform the following function:<\/p>\n<p>Unlock the remaining doors.<br \/>\nLock All Doors<br \/>\nPress the transmitter LOCK button to perform the following functions:<br \/>\n\u2022Lock all vehicle doors<br \/>\n\u2022Immediately turn OFF the interior lamps<br \/>\n\u2022Flash the exterior lights, if enabled through personalization<br \/>\n\u2022Chirp the horn, if enabled through personalization<br \/>\n\u2022Arm the content theft deterrent (CTD) system, if equipped<br \/>\nVehicle Locator\/Panic Alarm<br \/>\nA single press of the panic button performs the following functions:<br \/>\n\u2022Pulses the horn three times<br \/>\n\u2022Flashes the parking lamps three times<\/p>\n<p>A press and hold of the panic button performs the following functions:<br \/>\n\u2022Illuminates the interior lamps<br \/>\n\u2022Pulses the horn and flashes the parking lamps for 30\u2009second or until the following conditions occur:<br \/>\n\u25e6The panic button is pressed<br \/>\n\u25e6The ignition switch is turned to the RUN position with a valid key<br \/>\nRolling Code<br \/>\nThe keyless entry system uses rolling code technology. Rolling code technology prevents anyone from recording the message sent from the transmitter and using the message in order to gain entry to the vehicle. The term \u201crolling code\u201d refers to the way that the keyless entry system sends and receives the signals. The transmitter sends the signal in a different order each time. The transmitter and the BCM are synchronized to the appropriate order. If a programmed transmitter sends a signal that is not in the order that the BCM expects, then the transmitter is out of synchronization. This occurs after 256 presses of any transmitter button when it is out of range of the vehicle.<br \/>\nAutomatic Synchronization<br \/>\nThe keyless entry transmitters do not require a manual synchronization procedure. If needed, the transmitters automatically re-synchronize when any button on the transmitter is pressed within range of the vehicle. The transmitter will operate normally after the automatic synchronization.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Keyless Entry Do all 2011 Colorado crew cabs come with the remote keyless entry wiring or only the ones with the remotes.
