I'm having a Compustar alarm installed in my Clarity Touring next week. It's the same installer I've been using for years. He knows what he's doing. If anyone has any experience with installing alarms on the Clarity, or advice about what I'm doing, I'd like to hear it. I was discussing the Compustar alarm's options/possibilities with the shop owner. One decision I have to make is whether to use the factory remote transmitter to control the alarm, or to use one of Compustar's remotes. I'm leaning heavily toward using the Compustar remote. One problem with using the factory remote is that you are still vulnerable to relay signal theft. As great and convenient as they are, I've never liked these keyless smart entry, push-button start systems due to this vulnerability In order to use the Compustar remote, they would mount one of my factory remote transmitters in the car in a Faraday bag/cage. It will be hidden well away from any easily accessible location. The shop owner explained how it will work, but I'm not completely clear on the particulars. Using the factory remote, I remain vulnerable to relay signal theft. Using a Compustar remote, I will give up the remote climate start via the dedicated button on the factory remote (leaving only the smartphone app to start the climate control remotely). I will also give up the smart entry system and have to press a button on the Compustar remote to unlock the car. The main reasons I want an alarm are: 1) To protect the equipment I must often carry in my trunk. 2) To have auto locking/auto arming and auto relocking/auto rearming capabilities. 3) To be able to unlock and lock the doors through a smartphone app. 4) To be able to set up geofencing. 5) To have a windshield-mounted keypad that can disarm the car should I lose my remote. Auto locking/auto arming is a feature where you can set the alarm to lock the car and arm the alarm after a set period of time after you close the last door/trunk (usually 30 or 60 seconds). Auto relocking/auto rearming relocks and rearms the car after a set period of time if the car is unlocked/disarmed. Basically, these features mean you always know your car is locked and armed. The windshield-mounted keypad (called "RPS Touch") is something I really want because it will allow me to disarm and drive my car without having any remote, mechanical key or smartphone (other than the hidden remote in the Faraday cage). It mounts under the glass in the corner of the windshield and can sense your touch through the windshield.
