Well, Let Them Try

Some say the only purpose of a car alarm is to let you know someone has broken into your car. While that alone is a good reason to have an alarm we also expect a bit more. An efficient alarm system should try to prevent theft and ward away anyone who actually breaks in. The AutoPage C3-RS727A-LCD 2-way remote start car alarm makes a great addition to any vehicle with or without a factory alarm system. The alarm system comes with a dual stage shock sensor that detects movement outside and inside the vehicle. If movement is detected the included siren will activate to ward off any possible thieves. With 4 available channels you can add more security components to your system such as a tilt sensor, glass break sensor, window roll up module, etc.

The biggest advantage of the AutoPage alarm system is the LCD remote control. This 2-way AM/AM transmitting remote displays the state of your vehicle, which most factory car alarms don’t have. From the remote you can see the internal car temperature, time, if the doors are locked or unlocked, any attempted break-ins, if your car is turned on (if remote start is connected) and much more. If you remote start your car the 2-way LCD remote transmitter will give you a visual conformation that the engine is running, a run timer and countdown timer.

For those of us with diesel engine vehicles this alarm has a diesel setting with a warm up function. If you turbo charged your car often times you have to let it idle for a few minutes to give it a chance to cool off, the auto page alarm comes with a turbo timer that automatically shuts the vehicle down after a few minutes. The AutoPage C3-RS727A-LCD 2-way remote start car alarm offers a host of useful features and works on virtually all vehicles. For functionality, peace of mind and protection AutoPage has you covered!

Keyless Entry

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.

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.

great buy

January 24, 2010

I really liked the price of this alarm. My friend got one for $250 and he works at the place he got his from. It is easy to use and i like how the alarm shows what is going on with your car. I have not had any problems with this alarm. I am thinking of getting another one for my other car. Words of advice keep the instruction manual and read it often.

Does it all

June 2, 2009

Really happy with this Autopage system. Although, being not one to work on a modern car's electrical system I had a professional install it. Really happy with the operation. Did take getting some use to with having to override the factory alarm, but it really does do it all.
