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.

LCD Remote

LCD Remote

Receive visual confirmations from your vehicles security system or remote start system. Features such as remote start, lock/unlock, arm/disarm and trunk release will appear on the remote’s screen with its current status. An LCD remote can display warning icons when the doors, trunk or hood are open. If your vehicle is tampered with, some remotes display what part of the vehicle was affected.

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

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. These sensors let would-be thieves know that your vehicle is equipped with an advanced alarm system and to keep away.

Dedicated Trunk Release

Dedicated Trunk Release

This unit comes with trunk release capability and remote control integration for OEM alarm or add-on trunk release systems. Pop your trunk using your remote transmitter for convenience and ease of use. Carrying a handful of groceries? Arms tied up with luggage? Pop the trunk without using your key so it’s open and waiting for you when you arrive.

2-Way Paging

2-Way Paging

Send commands to your remote start or alarm system and receive confirmation that those commands were carried out. Obtain updates on your vehicles security status and get driver pages on the remote. If your vehicle is being tampered with, your remote transmitter will warn you and set off the vehicles alarm.

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.

Keyless Entry 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

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.

Some higher end car alarm systems can support multiple vehicles. This is the number of vehicles that the works with.
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.

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”.

good product.

April 8, 2012

I recommend your product to my friends because it's very helpful. Two of my cars have your alarm with the option to start with my remote control. I live in Seattle where most early morning and night were cold. So before you get in to your car it's been warm and ready to roll.

Got the job done at the right price

January 15, 2013

My first install of a car alarm and starter. It worked great right out of the box. Easy to setup and get used to.

Only Con I found is that the two remote eats up batteries and the battery cover broke after the 2nd time of taking it off.

installed on 2000 honda Odyssey

September 1, 2011

This system works great. Only complaint is the life of the 2 way remote battery, 1 AAA seems to die often. using bypass module to simulate key in ignition. Installed myself but it can be tough to do.

Awesome Bang for your Buck

October 29, 2011

This product is pretty simple. Me taking my time, no rush, and first time ever installing remote start it took me 5 hours. Everything works, keyless entry, remote start, the door sensor and shock sensor and trunk release. Still debating if i want the the hood pin installed. But the remote start feature, when you read the manual on how to program the system to remote time and long siren, the different branch modes thats adjustable. The system can learn the true RPM time so it can start the car everytime the first time. My car starts the first time even when it's extremley cold. The tru rpm tech mode allows it to do that which is great. The horn/siren is loud when it goes off. All 2 way pagers has a delayed reaction when the alarm goes off and you want to shut it off because it first sends the pager a signal on what cause the alarm to go off. But the single pager is instant. Oh, the 2 way pager can be programmed to automatically start your car at a program timed every day. That's a great feature. And it shows a timer for how long the car has been running. I tested this pager to remote start in the city to easily remote star at 1/4 mile measured distance. This alarm is loud. And an added feature is you can set from the antenna inside the car to turn of the alarm with a code if you need to get in the car without the keypad. The key is to make sure you learn how to enter the program branch mode so you can make the alarm learn the cars TACH. the tach/rpm wire is normally on if the wires plugged into the coil pack where your spark plugs are. The car learns the real time rpm in 1 second! So you don't have to worry about it killing your starter. It will start it better than you, trust me. Maybe i'll post a video review if someone wants to learn how to program the system to customize it. Install the shock sensor where it's easy to get to because you can dial in the sensitivity! that's all i can think of.

Works great, have installed dozens of these in the past year, have not had any problems, very easy installation compared to other brands, the tachless mode works perfect every time. No need to waste time hunting for the tach wire. And excellent price.

Great Value

January 11, 2015

It works great, good distance. The install was a little challenging. The instructions were good for the unit, however, spent some time researching my vehicle's wiring diagrams. Will need to purchase relays, they don't mention that .

is it compatible with all vehicles, specifically 2013 ford expedition el?
denise d on Dec 18, 2014
Best Answer: Hello Denise,

Yes, kits like the 4000RS are fairly universal. However, the "Vehicle Specific" part will fall within the Remote Start Feature; to access that feature your vehicle calls for the Bypass suggested on the page, the Omega OL-MDB-ALL.

what is the data bus port used for?
josh m on Oct 27, 2014
Best Answer: The Data bus port will be used to plug an external data immobilizer bypass. This module is required if your vehicle is equipped with an immobilizer. However, most of them can be used without the data bus port, but that means that it requires you to make the connections instead of just plugging a connector.

This has a data bus port does that mean I still need to buy a bypass module?
Chris I on Nov 4, 2014
Best Answer: Hello Chris,

It looks like no users have chimed in, so we will. The Bus port is meant For the Bypass, it does not imply it Has one. Use the link below to determine if the OL-MDB-ALL will work for your vehicle.
