Notable Features of the AVITAL 5303L Review

1) Remote Start 

The remote start feature on the Avital 5303L system allows you the freedom of starting a vehicle’s engine without the need for a key or for physical contact. 

It is convenient for adjusting the temperature of the cabin and engine of the car, which means in cold climates you can increase the heat and in hot climates, the temperature can be brought low.

With this feature, all this can be done from a remote location. Apart from the convenience, this is also important for the personal security as it reduces the time used to warm up the car engine.


2) Two-way LCD Remote

This remote allows you to receive visual and audio alerts and notifications from their vehicles in real time. The two-way LCD remote also enables you to start the car engine remotely, arm or disarm the car alarm system, lock or unlock the car door, control the car trunk, etc. 

This remote can also show, in color, specific parts of the car that are being affected or tampered with. All of this is possible because of the two-way paging technology incorporated in this remote.

3) Keyless Access Enabled

This feature allows you to lock and unlock the car doors, without having physical contact with the vehicle or without the use of a key. This is possible because the one-way remote sends a digitally encoded message as a radio frequency.

This frequency can only be detected by a specific vehicle and that prevents car thefts.

4) Shock Sensor Feature 

The car alarm system is fitted with a dual zone shock sensor. Using beeps and chirps, this feature warns the car owner about minor disturbances, but once it senses any serious disruptive activities the alarm is tripped.

The sensitivity of this dual shock sensor is adjustable so as to reduce the occurrence of false alarms but still sensitive enough to warn mischievous elements away.

With a Nuisance Prevention Circuitry (NPC®), the Avital 5303L is equipped with an anti-false alarm technology that is neighborhood-friendly.

5) Trunk Release Feature

The Avital 5303L system comes with the ability to enable keyless trunk release without any physical contact. This is done by using the one-way remote which sends the appropriate command through radio signals to the vehicle.

A feature like this is quite convenient especially when you have been shopping and have no hands free.

6) Compatible with Directed® SmartStart 

A really handy feature is the compatibility of the Avital 5303L device with the Directed SmartStart software. This feature allows car owners to connect to their Avital car security system through a mobile application on their smartphone.

Through the SmartStart mobile app, you can track your car anywhere through GPS technology. This is useful for finding a stolen car. Also, through this app, a smartphone can function as a more powerful remote control.

This is because it is not limited by the range of the two-way pager but instead uses cellular networks. This feature requires a subscription and a lot of car users cannot regularly afford this cost.

  • Fitted with Nuisance prevention circuitry to cut down on false alarms.

FAQs – Frequently Asked Questions on Avital 5303L Review

What is the distance of the remote sensor range?

Typically, the range of the remote sensor covers a distance of about 800 feet to 1,500 feet. 

This range depends on the presence of obstacles between the transmitting remote and the receiving vehicle.

Another affecting factor is the presence or absence of interference from cell-phone towers, radio antennas, television signals, etc.

If these interfering factors are nonexistent, then (within the range) a smooth one-way or two-way interaction between the remote controls and the vehicle can take place.

Can I turn my car on to warm it up if it is snowing outside?

Yes. Because of the remote control feature, it is very possible to sit in the comfort of your home while heating up your car engine and cabin.

Just at the push of a button, the command is sent through radio signals to the vehicle, where the car engine is promptly turned on and the cabin temperature increased to your preference.

Although, a car that is turned on remotely stays active for an average of twelve (12) minutes. After this, it automatically goes back off. This is to save gas from waste.

How do I get my purchased Avital 5303L installed?

A professional installer will have to be contacted. Although the remote car starter installation cost is quite pricey, it is necessary that a professional does this for you.

This is because they have been trained in the intricacies of the working parts of a car security system. So, they know how to install the security system appropriately.


This Avital 5303L review concludes that, this product might not be full of features, but it gives users value for their money.

This security system does not have a considerable range of coverage, but it is sensitive enough to differentiate between serious attempts at intrusion and fall alarms caused by rodents and harmless people. 

This automotive security system comes at a price that is quite comfortable for anyone who wants a good product guarding their vehicle.

The product also comes with a limited lifetime warranty, which informs that the company stands by their products.

After considering all these factors, we rate Avital 5303L 4.3 stars out of possible 5.
