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
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.
Yes
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.
No
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.
Yes
2-way Paging
Alarms with 2-way paging inform the user via remote vibrating/audible/visual alert when the alarm is triggered. The pager must be within range to receive the transmitted signal.
Yes
Number of Remotes
The number of remotes included with the alarm system purchase.
1
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.
4
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.
Button(s)-only with LED Lights
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.
Optional (Accessory required and sold separately)
Number of Vehicles Supported
Some higher end car alarm systems can support multiple vehicles. This is the number of vehicles that the works with.
2
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.
Recommended
Built-in Bypass Module
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.

Alarm Features

Paging Range
The maximum distance that the car alarm system will work with the wireless remotes.
500 Feet
Number of Car Alarm Channels
The total number of channels that the car alarm system supports. These channels can include locking and unlocking doors, opening the trunk, remote start, and many other options.
3
Shock Sensor
The shock sensor is designed to trigger an alarm on light or heavy impacts and vibrations (standard sensor included with most alarms).

A dual zone shock sensor is a feature of proximity and shock sensors only. Zone 1 ( light impact on shock sensor and short motions(adjustable) on proximity sensor) will trigger warn away chirp to warn intruder that car has an alarm without setting off the full alarm. Zone 2 (heavy impact on shock sensor and extended motions(adjustable) on proximity sensor) will trigger the alarm to “go off”.

Tried 2, both defective

July 17, 2015

I've had pretty good luck with ScyTek alarms in the past. Their remotes look nice and are sturdy. The simple design of the alarms have worked well for me before, but not this time.

After spending several hours wiring everything into my vehicle, I tested the alarm and the park lights would flash really fast instead of the normal one or two flashes. The trunk circuit didn't work at all, and the shock sensor was dead, due to bad glue on the sensor disc inside. I installed this unit into a 96 toyota camry. All the circuits I connected to have ground side switched relays that draw 160 mA (much less than the 500 mA limit of the alarm). I checked and double-checked everything.

Having spent all that time installing the alarm, I ordered another one, so I could get a plug- and play replacement. Unit #2 had exactly the same defects. Broken shock sensor, trunk and park light circuits don't work.

Moral of the story: Stay away from ScyTek. Directed Electronics (Viper, AutoStart, Clifford, AstroStart, AutoMate, Python, Avital) products work. Spend the extra cash and save yourself hours of time and headaches.

What wire on this A20 alarm is the starter kill wire?

I have an older car (1987 VW vanagon), w/o power locks. I don't need remote start, keyless entry or fancy features. Can I install this 'ScyTek A20' to have a basic alarm with a fob 'arm/disarm'? Could I add on an air-pressure sensor?
