Our take on the Code Alarm CA1554

Even vehicles with keyless entry don't necessarily have a built-in security system. So go ahead and protect your investment with a security system that includes features like an impact sensor and 2-way communication with your car. Code Alarm's CA1554 security and keyless entry system protects your car and its contents with these features and more, and even adds remote door lock and unlock if your vehicle has a power door lock system. The system's 2-way remote features an LCD screen for instant feedback on the status of your alarm and car, even when it's out of sight.

Add security to your mobile lifestyle

Even vehicles with keyless entry don't necessarily have a built-in security system. So go ahead and protect your investment with a security system that includes features like an impact sensor and 2-way communication with your car. Code Alarm's CA1554 security and keyless entry system protects your car and its contents with these features and more, and even adds remote door lock and unlock if your vehicle has a power door lock system. The system's 2-way remote features an LCD screen for instant feedback on the status of your alarm and car, even when it's out of sight.

The system includes:

  • one metal-clad 2-way remote with LCD screen, plus one metal-clad 4-button 1-way remote
  • a dual-stage magnetic shock sensor that detects unauthorized tampering;
  • a powerful 125 dB weatherproof siren;
  • remote door lock and unlock;
  • a starter interrupt feature which shuts down ignition during unauthorized use.

Additional security features

The CA1554 provides additional peace of mind with ignition-activated door locks and carjacking protection. The system also features 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 starter interrupt function prevents hot wiring, so your car will stay where you parked it. You can expand your convenience and protection even more by adding optional sensors or actuators to the five auxiliary channels, so you can flash the dome light or open the trunk with your remote.

Lost in the lot?

Everyone knows how hard it can be sometimes to find your vehicle in a crowded parking lot. The Car Finder feature will sound your alarm or horn at low volume at first, and then progressively louder, so you can find your car quickly.

Alarm Features

Alarm Features

Overview: The Code-Alarm CA1554 Vehicle Security and Keyless Entry System, a part of the Professional Series line, will protect your vehicle and its contents, and can remotely lock or unlock your doors. It comes with two remotes.

Remotes: The CA1554 comes with one 2-way, 5-button LCD remote transmitter (CATLCD), and one 1-way, 4-button remote transmitter (CAT4). Both remotes operate at 433 MHz to give you a range of approximately 2500 feet. Additional remotes (up to a total of 4) can be programmed to operate the alarm. Details of the remotes include:

  • CATLCD 2-way LCD Remote: The illuminated LCD remote receives feedback from the alarm so you can check the status of your vehicle. Numerous icons indicate at a glance if the doors are locked or unlocked, the current alarm mode, and which triggers have set off the alarm. Additional convenience features include an alarm clock and a parking meter timer. The remote can also operate a second alarm system once the remote has "learned" all of the second system's codes. The LCD remote has 5 buttons for lock, unlock, vehicle locator/panic mode, trunk, and function. It requires one AAA battery (included).
  • CAT4 1-way Remote: The 1-way remote contains four buttons for lock, unlock, vehicle locator/panic mode, and trunk. Requires one CR2016 battery (installed).

Programmed Transmitter Notification: Each time the vehicle's ignition is turned on, the status LED (on the glass-mount antenna) will flash with the number of transmitters programmed into the system. This security precaution helps you identify unauthorized transmitters and prevent them from accessing your vehicle.

Glass-Mount Antenna: The included glass-mount antenna includes two LEDs and the valet switch built in. Typically, the antenna is mounted high on your windshield near the rear-view mirror, using the provided dual-sided adhesive pad. This location gives you optimal range for the remotes, high visibility for the status LEDs, and a convenient location for the valet switch/programming button.

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 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 interfaces 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 CA1554 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" footprint diameter, 3-3/8" 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. The Silent Choice feature requires a second press of the "lock" button to activate an audible arming response from the vehicle. This feature is set to 'off' as the default.

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.

Delayed Arming: For vehicles with a delayed dome light, the system can be programmed to delay arming up to 60 seconds after the lock button is pressed. Once programmed, the system will learn the timing of the dome light delay and add 2 seconds before arming.

Door Locks/Trunk Release: 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. In addition to unlocking and locking the doors, the system can also open the vehicle's trunk or hatch.

Note: When interfacing with any other type of factory door lock system besides negative switching locks, or when using aftermarket door lock actuators, two SPDT relays (such as 120E5000) will be needed. If your vehicle requires the use of a Data Integration module that controls your factory door locks, no extra parts besides the Data Integration module will be required.

Two-stage Door Unlock: The alarm's door lock function can be set to operate in two stages. The driver's door only is unlocked with one press of the unlock button. A second press of the button within 3 seconds will unlock the remaining doors.

Shock Sensor: The included dual-stage magnetic shock sensor will cause the system to 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.

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.

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.

Hidden Alarm Function: The Hidden Alarm function allows you to arm the system with the siren and horn output silenced if the system is triggered. The LCD remote will still indicate if the alarm is triggered during the Hidden Alarm function.

Progressive Car Find: To assist you in locating your vehicle in a crowded parking lot, the Progressive Car Find 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.

Carjack Mode: The CA1554 features a Carjack mode, which must be turned on in system programming. The Carjack mode 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.

5 Auxiliary Outputs: The alarm features 5 auxiliary outputs to operate optional accessories such as power windows or sunroof, or a powered sliding door. These 500mA 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.). You can access Aux 1 by pressing 2 buttons on the remote. For the additional Aux 2 through Aux 5 outputs, you will need to enter an Aux Mode, which will "shift" the transmitter functions from their standard operations to control the Aux outputs. Once you have entered Aux Mode, outputs Aux 2 through Aux 5 can be activated by pressing and holding one of the remote buttons for 3 seconds.


Universal Transponder Interface (UTI): The optional Universal Transponder Interface works with vehicles that use an "immobilizer" key system, allowing you to operate the alarm system without interfering with the vehicle's anti-theft features. The UTI works with vehicles that have a transponder or RF-based immobilizer, including the GM Passkey systems.

Digital Tilt Sensor: The optional Code-Alarm DUB1 digital tilt sensor can detect when the angle of your vehicle changes and trigger the alarm to protect you from tow trucks and tire or wheel thieves. After you have parked your vehicle, the DUB1 has a digital self-leveling feature to determine the angle of your parked vehicle. If that angle changes due to the vehicle being jacked up or towed, it will trigger a full alarm in the security system.

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 CA6154'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.
