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.
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.
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.
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.
Built-in Bypass Module
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.

Convenient Features

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.

Remote Start Features

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.

Installed in my nissan versa with intellikey

October 27, 2014

I just finished installing this into my Nissan Versa with intellikey. I haven't done any work on my car before and as such made sure I had a 4 day weekend to do the install. I overestimated and was able to get it done in about one day's time. The manual is fairly clear with the exception that the bypass unit (MDB ALL) indicated that the Ground and Neutral wiring from the unit isn't needed if you use D2D mode. This is incorrect. Other than that everything works well and the range is easily a mile.

Excalibur's technical support is excellent. Phone support was right there for me Monday morning to troubleshoot my last connections and get me running. Sonic Electronix on the other hand left me wanting a bit. When I originally got the MDB ALL it wasn't programmed. This resulted in me mailing back the unit and having to wait a while until I had another free weekend. On top of that the support staff gave me the number for Metra installation support (Metra makes stereo equipment, not remote starters). Sorry Sonic, you dropped the ball.

With this type of install if you are someone who has done electrical work on your vehicle or you have done highly detailed electrical work of any sort this is something you can tackle. If you've never worked with electrical systems before and are not familiar with soldering, wire tying, heat shrink, or electronics in general you probably should just head to a pro.

Why did you choose this?
Sonic Electronix Store
I needed a simple remote start for my Nissan with intelikey. This has worked great for me over the last 6 months.

is this compatible with a jeep tj?
A shopper on Dec 7, 2014
Best Answer: Hello,

Yes; Kits like the 251-EDP are Universal. This is why the description omits a Vehicle Compatibility list.

Depending on the Year of the vehicle, you may also require a bypass. That is easily established by putting in your vehicle information into the fit guide below.

We encourage you to contact the manufacture to ease any concerns.
