About the Code Alarm CA1155e Elite

Secure your vehicle

Your car may have a keyless entry remote, but that doesn't mean you've got a security system built in as well. And even if you have a factory-installed security system, very few of them include a siren and a tilt/impact sensor, for instance — essential features if you want to stop a thief from smashing a window and taking what they want.

Secure your vehicle

Your car may have a keyless entry remote, but that doesn't mean you've got a security system built in as well. And even if you have a factory-installed security system, very few of them include a siren and a tilt/impact sensor, for instance — essential features if you want to stop a thief from smashing a window and taking what they want.


Code Alarm's CA1155e Elite keyless entry and security system protects your car and its contents with a tilt/impact sensor and more, and gives you the convenience of remote door locking. The dual-stage shock sensor system's siren chirps a warning with the first sign of trouble, then goes off full blast if the intrusion continues. The system includes:

  • a dual-stage tilt/shock sensor that detects unauthorized tampering
  • a powerful 125 dB weatherproof siren
  • two 4-button 1-way remote controls
  • remote door lock and unlock
  • two-stage door unlock opens driver's door first
  • a starter interrupt feature which shuts down ignition during unauthorized use
  • DBI port for direct interface connection
  • auxiliary output for additional user-defined functions

More features

Ignition-activated doorlocks, carjacking protection, and automatic rearming provide additional safety features. The CA1155e also has an override switch for valet parking, while the "silent choice" feature allows you to arm and disarm your car alarm without disturbing your neighbors. The car-finding feature will sound your alarm at low volume so you can find your car quickly in a crowded parking lot.

Important Note:
We offer an interface that can save you lots of time when you install a Code Alarm system in most vehicles. For a limited time, you can save $40 on the interface if purchased with this Code Alarm system. Chat or call us at 1-888-955-6000 to see if the interface will work with your vehicle.

If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this security system yourself. If not, please consider having your system professionally installed.

To ensure vehicle compatibility, please enter your vehicle information. Your order will be reviewed by our Car Experts group, who will contact you if further information or recommended accessories are needed.

Product Research

Alarm Features

Alarm Features

Overview: The Code-Alarm CA1155E Vehicle Security and Keyless Entry System, a part of the Elite Series line, will protect your vehicle and its contents, and can remotely lock or unlock your doors. The CA1155E comes with two remotes.

Remotes: The CA1155E comes with two 1-way, 4-button remote transmitters (CAT4P). The remotes have four buttons for lock, unlock, vehicle locator/panic mode, and trunk release. Each requires one CR2032 battery (installed).

Data Bus Interface (DBI) Port: The alarm's control module has a 4-pin Data Bus Interface (DBI) port, which allows you to plug in an optional FlashLogic FLCAN Transponder/Door Lock/Remote Start Interface directly into the system. These modules, compatible with many late model vehicles, can save considerable installation time by eliminating the need to find and splice various wires within the vehicle. Typical connections that are made with the interface include tachometer, brake, door locks, and ignition/starter.

Note: Even with the interface, there will be some required splicing into your vehicle's factory wiring.

125dB Siren: The CA1155E includes a siren which emits a single tone pattern at 125dB, which is equal to the threshold of pain in humans. Its compact size (2-3/4" x 1-5/8" footprint, 2-1/4" horn diameter) gives you additional mounting flexibility. The weatherproof design keeps the siren operating flawlessly in the harsh, under hood environment.

Silent Choice: The Silent Choice feature allows you to control the arm/disarm chirps from the remote control. When Silent Choice is activated, a second press of the "lock" button is required to activate an audible arming response from the vehicle. The system default is Silent Choice disabled, which means the alarm will chirp for arm and disarm on the first button press.

Active/Passive Operation: The system can be programmed for passive or active arming and door locking. Active arming/locking requires the use of the remote to arm the system or to lock the doors. When programmed for passive operation, the doors lock and the system is armed automatically 1 minute after the last door is closed.

Door Locks: The alarm can lock and unlock the vehicle's doors using the remotes. The alarm can be wired to work with positive or negative switching locks, reverse polarity, and positive or negative multiplexed door locks. Two door lock relays are built into the system.

Trunk Release: The CA1155E includes a trunk-release ground (-) output that can open a vehicle trunk or hatch (additional relay may be required, sold separately).

Built-In Sensors: The alarm housing features two built-in sensors:

  • Dual-Stage Shock Sensor: The included dual-stage magnetic shock sensor will respond with a warning chirp when there is a light impact to the vehicle. Harder impacts will fully trigger the alarm. You can bypass the shock sensor for one arm cycle, and will default back to normal operation the next time the system is armed. The shock sensor's sensitivity can be adjusted if needed.
  • Tilt Sensor: An internal digital tilt sensor can trigger the alarm if the vehicle is raised on a jack or towed. Settings include: 3 Degrees, 1 Degree, and Off

Starter Interrupt Output: When the alarm is triggered, the system will disable the vehicle by interrupting the circuit to the starter via a relay. As long as the system is in alarm mode, the vehicle's engine cannot be started, preventing a possible theft. The relay needed to install this feature is included with the alarm.

Auxiliary Output: The alarm features an auxiliary ground (-) output to operate optional accessories such as power windows or sunroof, or a powered sliding door. This output is capable of driving relays, and can be programmed to operate in various timing configurations (i.e. push and hold, latched, latched until ignition on, etc.).

Parking Light Flash: The CA1155E includes a built-in relay for activating your parking lights during arm/disarm and when the alarm is sounding. A Parking Light Output wire connects to the vehicle's parking light wire, while a Parking Light Input wire lets you connect to either power or ground, depending on the parking light circuit polarity.

Dome Light Delay: The alarm system can be programmed to delay arming after the Lock button is pressed (up to 60 seconds), for vehicles with a dome light delay or "theater dimming" feature. Once programmed, the system will "learn" the timing of the dome light delay and add 2 seconds before arming.

Personal Protection Alarm Mode: The alarm's Personal Protection or Panic Mode will activate an alert when you press and hold the panic button continually for three seconds. The transmitter's normal functions are suspended during panic mode, except to allow you to lock or unlock the doors. You can manually shut off the alarm with the transmitter, or the system will automatically stop after 30 seconds.

Real Panic Sound (RPS): During panic and alarm trigger modes, the horn and/or siren will sound in a randomized pattern. This draws more attention to the vehicle than alarms without this feature.

Progressive Car Finder: To assist you in locating your vehicle in a crowded parking lot, the Progressive Car Finder feature will sound the alarm and/or honk the horn five times at low volume. If you have not located the vehicle, the system will repeat the action at increasingly higher volumes (low, medium, high) with each press of the button.

Anti-Hijack Mode: The CA1155E features an Anti-Hijack mode which, when activated, provides a delayed and progressive alarm response, starting with siren chirping, to full alarm with flashing parking lights, to starter kill activation, rendering the vehicle disabled. Anti-Hijack mode can be a activated in the programming options.


FlashLogic Interface Module: The optional FlashLogic FLCAN Databus Interface Module communicates with your vehicle's Databus to provide plug-in capability for various functions of the Code-Alarm security system. Typical functions include tach input, door trigger, dome light supervision, factory alarm arm/disarm, trunk/hatch open, diesel glow plug input, remote start, and factory keyless entry controls. Compatibility and available functions vary depending upon year, make, and model of vehicle.

Note: Before installing, the FlashLogic module will need to be configured for your specific vehicle via web-update. Some splicing into factory wiring will be required.

Carlink Cellular: Activation of the CA1155E alarm and select features can be achieved with one of Code Alarm's optional Carlink smartphone interfaces. The ASCL6 lets you control the system over a 3G network via your smartphone using the CarLink app. The ASCLBTL is available for long-range operation, up to 1.5 miles, by using a supplied RF remote that gets paired to your Bluetooth-enabled smartphone. Your smartphone can operate can be up to 150' from the remote control and still control the CA1155E.

Door Lock Actuators: Power door locks can be added to a vehicle with manual door locks with a Door Lock Actuator, enabling you to lock/unlock your doors with the CA1155E's keyless entry feature. A Standard 2-wire Door Lock Actuator is available for normal manual door locks. For cable-driven door locking systems, a Motor Clutch-type Door Lock Actuator and a Cable Kit will be needed. You will need an actuator for each door you want to control.
