Our take on the Code Alarm CA1153

by Buck Pomerantz
Code Alarm

We offer vehicle-specific interfaces that you'll need to complete your car security installation. Please identify your vehicle as we review every order to make sure you've got everything you need.

Upgrade your security

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 an impact sensor — an essential feature if you want to stop a thief from smashing a window and taking what they want.

Great features, powerful protection

Code Alarm's CA1153 keyless entry and security system protects your car and its contents with an impact sensor and more, and gives you the convenience of remote door locking. The dual-stage shock sensor chirps a warning with the first impact, then goes off full blast if the intrusion continues. The system includes:

  • a dual-stage magnetic shock sensor that detects unauthorized tampering;
  • a powerful 125 dB weatherproof siren;
  • Real Panic Sound randomizes siren/horn warnings to attract more attention
  • two metal-clad remote controls;
  • remote door lock and unlock;
  • a starter interrupt feature which shuts down ignition during unauthorized use;
  • DBI port for direct interface connection

But wait, there's more...

Ignition-activated doorlocks, carjacking protection, and automatic rearming provide additional reassurance. The CA1153 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. You can expand your protection even more by adding an optional sensor to the auxiliary input. 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.

Alarm Features

Alarm Features

Overview: The Code-Alarm CA1153 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 CA1153 comes with two 1-way, 4-button remote transmitters (CATX-MT). The remotes operate at 433 MHz with additional SAW filtering to give you excellent range with less RF interference. The remotes have four buttons for lock, unlock, vehicle locator/panic mode, and trunk release. Each requires one CR2016 battery (installed). Additional remotes (up to a total of 4) can be programmed to operate the alarm.

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 (220FLCAN) 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 CA1153 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. 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.

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. Two door lock relays are built into the system. In addition to unlocking and locking the doors, the system can also open the vehicle's trunk or hatch.

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 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 that alarms without this feature.

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 CA1153 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.

Auxiliary Output: The alarm features an auxiliary output to operate optional accessories such as power windows or sunroof, or a powered sliding door. This 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.).


FlashLogic Interface Module: The optional FlashLogic Databus Interface Module (220FLCAN) 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.

Universal Transponder Interface (UTI): The optional Universal Transponder Interface (UTI) 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 CA1153's keyless entry feature. A Standard 2-wire Door Lock Actuator (220DA1) is available for normal manual door locks. For cable-driven door locking systems, a Motor Clutch-type Door Lock Actuator (220DA2) and a Cable Kit (220CLBK) will be needed. You will need an actuator for each door you want to control.

1-way Remote Transmitter: Up to 4 remote transmitters can be used with the CA1153 security system. Additional CATX-MT 1-way 4-button remotes can be purchased and programmed to operate your system.

Good solid basic alarm that does every thing I want. The manual could be a bit clearer, but understandable with some study.

4 answers
  • hello .. if it is a good alarm although I have not the car where the install but satisfied with the months that the use [ LUIS H   Feb 17, 2014 ]
  • Yes. But you have to activate as it is not a factory pre-set. This alarm has many options and auto arming is one of them. [ JEHU   Feb 14, 2014 ]
  • It is available but not a factory default. You have to program as an option under " programming options". [ JEHU   Feb 14, 2014 ]
  • yes. if you forgot to lock your car the system arms itself after like a minute or so. but the car is still open, so if someone goes to open a door the alarm will go off......if you hit the alarm lock on the key the car lock everything locks up. [ SHARON   Feb 13, 2014 ]
