Remote Start Car Alarm

Remote Start

Allows a vehicles engine to activate without physical contact from the user. This feature is useful for warming up your vehicles engine and transmission to operational temperatures. In cold climates you can have your interior hot or in warm climates you can cool it down before use. All of this can be done while in the comfort of your home or office.

Keyless Entry

Keyless Entry

Performs lock and unlock tasks without physical contact with the vehicle. Power door locks can be controlled from several feet away or even within a building using a remote fob. The fob emits a radio frequency that is digitally encoded to prevent frequency stealing so no one can enter into your vehicle without your wireless transmitter.

Dual Zone Shock Sensor

This shock sensor utilizes warning chirps for minor disturbances and will trip the alarm if it detects more serious impacts or disruptions. Most dual zone shock sensors have adjustable sensitivity to reduce false alarms or warnings.

General Features

Security System Type
This indicates whether the product is a security car alarm product, remote start module, or a combo unit that offers security with remote start features.

Security: This means that the car alarm system is just that. No bells and whistles, just a car alarm system.

Remote Start: when installed, this allows the user to start a vehicle from a remote location. Remote start modules and security with remote start alarms often require an additional vehicle specific bypass module to complete installation.

Security with Remote Start: This means that the system incorporates both features listed above.

Security with Remote Start
Car Alarm
If "Yes", the system will have alarm security features to help prevent vehicle theft and tampering. Remote start modules without alarm features will have "No" for this value.
Remote Start
If the alarm or remote start module has "Yes" for this value then the system has an electronic device that allows you to start your vehicle by remote control without actually being inside the vehicle or using the key. The remote start system supplies the vehicle with power and simulates a start just as if you were inside using the key. Select vehicles require additional accessories or immobilizer/bypass modules to use the remote start feature.
Keyless Entry
Keyless entry allows you to remotely lock, unlock, and open the trunk of a vehicle if that is equipped with power door lock motors (actuators) and power truck motor (solenoid). Door lock controls via the remote are found on nearly all of today's car alarms.
2-way Paging
Alarms with 2-way paging inform the user via remote vibrating/audible/visual alert when the alarm is triggered. The pager must be within range to receive the transmitted signal.
Number of Remotes
The number of remotes included with the alarm system purchase.
Number of Buttons on Primary Remote
The amount of buttons on the Primary Remote generally equals the number of functions that you can use your remote for. Some remotes have auxiliary buttons which can perform more than one task per button.
Main Transmitter Type
LCD and OLED transmitters display various screen savers, warnings, alerts and other features on the face of the remote, rather than first generation button-only transmitters. They provide more information typically and other features.
Sidekick Remote Transmitter Type
Some car alarms and remote start systems come with more than 1 transmitter, which is referred to as the "sidekick" transmitter. Most LCD/OLED systems come with a button-only sidekick transmitter, while select units come with an additional LCD/OLED transmitter.
LED/Display Color
The color of the LED indicator(s) on various items such as button-only car alarm transmitters, various chargers, cell phone accessories and other products.

For OLED or LCD car alarm remotes/transmitters the display color refers to the color(s) of the screen.
Number of Vehicles Supported
Some higher end car alarm systems can support multiple vehicles. This is the number of vehicles that the works with.
Number of Auxiliary Outputs
The number of auxilary outputs that the car alarm system supports. These outputs are left over from the total number of channels. They can be used to add on other options or additional features to a vehicle.
PC Programmable
Custom, advanced programming options through one or more of the following: PC, Pocket PC, PALM Pilot, Valet SW or Remote Transmitter allows for advanced controls of your alarm's functions.
Smartphone Compatibility
These are the types of smartphone systems that the car alarm system is compatible with.
GPS Tracking
These car alarms enable a user to track the position of the vehicle using GPS satellites.
Professional Installation Recommended
This will indicate whether or not we recommend going to a professional installer for this item. Some items have complex installations that should only be done be professional certified installers.
System Type
This refers to the type of remote start system, whether it is an add-on or a complete kit.
Complete Kit
Replacement Remote Transmitter
Car alarm replacement remotes are used when you damage or lose your original remote that came with your alarm. Programming of the replacement remote is required and must be done on site where the alarm is installed in the vehicle. Some remotes can be used as an additional 2nd or 3rd remote on a car alarm system.
Optional (Accessory required and sold separately

Convenient Features

Panic Mode
Panic mode allow the user to be able to set off the alarm from the remote.
Trunk Release
The trunk release option allows for integration and control of the trunk latch. Additional parts may be required.
Valet Mode
Valet mode is a car alarm setting that adjusts system to less sensitive settings when allowing a valet to park your car and similar settings.

Alarm Features

Paging Range
The maximum distance that the car alarm system will work with the wireless remotes.
1,500 Feet
Number of Car Alarm Channels
The total number of channels that the car alarm system supports. These channels can include locking and unlocking doors, opening the trunk, remote start, and many other options.
Most car alarms come with a siren that can be installed. The siren will sound when the car alarm is triggered the alarm goes off.
Shock Sensor
The shock sensor is designed to trigger an alarm on light or heavy impacts and vibrations (standard sensor included with most alarms).

A dual zone shock sensor is a feature of proximity and shock sensors only. Zone 1 ( light impact on shock sensor and short motions(adjustable) on proximity sensor) will trigger warn away chirp to warn intruder that car has an alarm without setting off the full alarm. Zone 2 (heavy impact on shock sensor and extended motions(adjustable) on proximity sensor) will trigger the alarm to “go off”.

Dual Zone Shock Sensor

Remote Start Features

Cold Start Timer
Great for those on a set schedule who need their vehicle to warm up at a specific time every morning for example.
Turbo Timer
Some remote start systems have turbo timer feature which allows the vehicle to run for a specified amount of time after exiting vehicle. In turbocharged vehicles this prevents hot oil in the engine from choking up in the lines. Hard driving can raise engine oil temperatures to dangerously high levels. Proper cool down is essential for a healthy turbo and engine.
Compatible with Diesel Engines
This means that the remote start system will work with diesel engines.
Engine Start Intervals
Some remote start systems offer feature to protect your engine. The engine start interval feature will start the car at particular time intervals or when the engine has reached a certain temperature. This feature prevents the engine block from freezing.
Compatible with Manual Transmissions
This means that the remote start car alarm is compatible with manual transmissions. Please see the item description, manual, or your professional installer for more information as to how this feature will work with your specific vehicle.

Dallas, TX

great item for winter

December 24, 2013

I just recently got the crimestopper sp-402 with remote start and its great. Its my first car alarm and I installed it my self. With the Manual its pretty easy to install. The only think that sucks is the range if you have window tint just find a good place to mount the anntena. I got my alarm at a pretty good price compared to the other alarms and it seems the pirce went up a little but its still worth the buy.

Woodville, OH

Great Brand! Great Support! Cannot beat Crimestopper!

February 8, 2014

I purchased a Crimestopper SP-402 Car Alarm with Remote Start. Their design is much the same to the Car Alarm with Remote Start (CS-2011RS IV) I purchased back in 2006.... Still on my car today without a single problem! It was a great system then and the SP-402 is a better system for today. I installed my own system back then and today. It takes a little bit of common electrical understanding to install yourself. The instructions are great and so is the Crimestopper support. Just contact Crimestopper with purchase of new system and they will e-mail you a wire diagram chart for you specific car.

Great price for quality product!

November 27, 2013

Installation was easy with the instruction manual. Very responsive unit and tapping into the horn for feedback helps to ensure the signal was sent properly. I would recommend this unit to anyone looking for a remote starter.

i have a 1995 ford tarus gl, and I would like to know if I purchase the crimestopper sp 402 will it include everything needed to work on my car? thank you MR. RAGSDALE
A shopper on Feb 22, 2017
Best Answer: It should have everything. I am about 99% positive that vehicle doesn't need a bypass module which would be the only thing the unit wouldn't have with it. So you should be good to go. Now, if your vehicle had a factory keyless entry system, it will be negative triggered locks, if it didn't, then they are 5 wire locks and u will need 2 relays. But that is something you will have to look at when doing the install if you do not have the stock remotes for the factory keyless entry.

does this unit work with a 2004 nissian sentra?
Mister J on Feb 5, 2017
Best Answer: i got that same one for my 2006 chevy i.pala ss and its has the bypass for the remote start i have all power everything in my car so i do not see why it would not work for your car as long as you have power locks ot if you even have the remote start or not you will need the bypass as well iam sure for it to work with the remote start system but as for just an alarm it should be fine

My crimestopper alarm system light which is located on the left of my steering wheel on the dashboard became lit (which means my alarm is active) while I was in the car. The blue light will not go off even after the car has been parked and shut off. Any solutions to this problem ?
shawn c on Oct 12, 2015
Best Answer: You have the valet button on.when the light is on steady that means the valet option is active. You must switch it back to the normal mode.
