Effortless and Intuitive

Viper's new Responder LE transceiver is a vehicle security and remote start system. The 2-Way remote controls are sleek and sophisticated as they feature an industrial design, made to fit the user's hand comfortably. With an effortless and intuitive single-handed operation, the hidden GhostLight LEDs confirm your every command. Not only do the GhostLights confirm your commands, it will check the vehicle temperature as well.

The Responder LE remote is a state-of-the-art system with features you can access with ease, starting with the new paging-only Silent Mode2 feature. This allows users to turn off the siren and receive notification on the remote only. With Silent Mode2, the vehicle silently alerts the user that the alarm has triggered. The remote has simple new universal icons with soft touch surfaces for comfortable handling.

Responder LE will help protect your vehicle and its contents, start the engine with the push of a button, and confirm all commands with GhostLight LEDs. And it will do it all with ease, style and a one-handed operation.

Remote Start Car Alarm

Remote Start

Allows a vehicles engine to active 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

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.

Great Value!

Great product, I did have it professionally installed. It has worked great, well worth the price. Range on remote is great. The only con is- cant use door lock on truck, must use alarm key pad or alarm will sound upon returning.

good product

I would definitely recommend this product for the price. The only thing negative I have to say about it is make sure you either know how to hook them up or know someone who will do it for cheap (thats if your cheap like me) because going to a sound store is going to cost you a good piece of change.

customer courtesy

I called regarding a remote start/ alarm. I was very pleased with the price of the item and the friendliness of the service that was given. Every detail was explained regarding any questions that were asked. I am really satisfied with everything. Crystal ex.2194 is the best. She really knows her job. Thank you for everything.

Great buy

I already have the viper 5701 in my truck and love it had it installed after my wife's suburban got stollen out of our drive in a nice area. After we bought her a new truck she wanted a security system in it. An 03 expedition. & was going to be a couple hundred more to have it installed in her expedition so I looked around and found it at sonic. Its been installed for about 6 months now with no issues. It is a great buy, if u have knowledge and experience installing electronic systems in cars. If not u should have it done by a pro. I'm experienced and had wire scimatics for my vehicle it took me about 10 to 12 hours to install it

It's a Viper :)

This alarm is another great product of DEI. everything works great as advertised. I put this alarm in my 2001 Ford Explorer and installation was as easy as finding the right wires. The remote start feature worked great over the winter. I also have the field disturbance sensor with the window automation feature installed. The only cons are the range of the 2 way remote and sometimes the response of the remote. When I push unlock or lock it will not work sometimes. No other problems. I am happy with my alarm.

Good buy with great value

It is a very good fit to my need, having a remote start and long range (less than a mile) control is a good feature for this model.
