Description


Never Go Back

When it comes to your vehicles security and safety, Python doesn't hold back. The Python 991 is a revolutionary way to secure you vehicle, while also receiving cutting edge convenience. 2-Way paging, remote start, a one mile transmitter range, priority icons, and 2 vehicle support are just a few of the feature packed security system. The Python 991 just about does it all!

 
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.

Rechargeable Remote

Rechargeable Remote

Going through batteries can end up being a costly endeavor. A rechargeable remote allows for more powerful transmitters and additional functions such as touch screen remotes and full color displays. These transmitters will remain at a consistent voltage during the discharge cycle to keep all functions working. With hundreds of recharges available, you save money on replacement batteries.

One Mile Range

One Mile Range

Operate functions of your alarm or remote start system and receive notifications from up to a mile away. Utilize necessary vehicle functions from great distances for convenience and versatility. Forget to lock your car? Lock it from in your office, at the mall or in class. Know if your vehicle is being tampered with wherever you are.

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.

Great Choice!

I was impressed with the product. It actually looked better in person than in the pictures. I was also able to track my shipment up until it's arrival. All pros no cons.

Python 991 AWESOME!!!!!

This system by far is the best. Though my installer had quite the time installing. He didn't have much experience but he finally got it installed. Love all the different features. The range on this thing is unbelievable. So far I haven't had any problems on starting up my car. Been did it through a few solid cement walls at 2500ft +. Haven't tried it at a mile yet. But that I am sure it wouldn't disappoint me. Remote is fairly easy to use once you get the hang of it. I use only the 2way since my car requires smart key in place of a key. Also 2way remote has a little plastic film on it to protect it from any scratches. I've kept the plastic on mine. Great product for Money!! Won't be disappointed!! I know I am not!!! Shipping was decent. Have bought from Sonic before!! I am sure as hell going to come back for more of my needs!!!!

Awesome remote starter

I would recommend this product to a friend because this product is great and easy to use, especially during the winter time. I only brought this product because I do not wanna go outside and start my engine. A good think about this product is it comes with two remote, the LCD remote has up to a mile range, well if there nothing blocking it signal. Another good thing is it has alarms too and when someone try to break
Into your car u would know because ur LCD remote inform u. The bad thing about the product is the LCD remote get scratch real easy so buy a protecter for it. Also, the second remote without the LCD does not have a mile range. Overall I think this is a great product

Great system for an unbelievable price!

This security system is worth any dollars you spent on it. I installed on my Lincoln Navi and so far didn't find any flaws in it.
