A:AnswerIt depends on which alarm model you have and what year make and model car or truck you have it installed in. The alarm is not likely to be the problem in a battery change since almost any alarm, even the more complex ones with GPS theft recovery, app based systems or remote starters, have internal memory that don't rely on the car battery and which can be taken out of the equation by simply activating the valet button or switch which will bypass the alarm completely and which you can deactivate after the new battery is installed. In most newer cars the computer will store enough information in memory so as to not loose data during a battery change, but in some slightly older cars (pre-2008) there can be issues with dead or disconnected batteries it is more likely in 80's to mid-90's (OBD-1) vehicles with earlier less advanced onboard diagnostics systems. To be safe, searching online forums dedicated to your specific vehicle would be a good idea and also a good resource for other model specific information. If you want to be absolutely sure you can always take your car to an OEM dealer or brand specific specialist service center to have them do the swap which will usually cost less than $50, or call one of these shops and just ask them if any special precautions are warranted. Also, there are devices made for just such situations that allow you to connect auxiliary power to either the OBD plug or a power outlet in order to keep 12 volts in the system while the battery is being changed. I know many auto parts stores have such devices on hand in order to allow them to sell more batteries and most of them will swap the battery for free as well. I hope some of this helps. Best of luck to you.

A:AnswerThis unit will work with existing door lock actuators, if your vehicle doesn’t have them, you will need to purchase actuators separately to utilize the remote door lock/ unlock feature. If you want to alarm your trunk or hood, you will need to purchase pins that are spring loaded and will be mounted to allow the alarm to know when they are opened while in alarm mode. As for the alarm portion of this item, you can usually wire it in with your existing vehicles wiring and it will work great, it will tie into the dome light to alert when alarmed if the doors are opened and the dome light turns on, or if you have a car with valet lights that turn in when the handle is tried. I like this alarm, there’s a few other features such as lamp on/ off for your headlights or parking lights and it comes with a relay for that option. It was somewhat straight forward and if you’ve ever done any alarms in the past it should be easy
A:AnswerViper offers several options in case you loose or damage your remote(s). First, most alarms come with 2 remotes anyway, second, there are severak other options from adding another remote, to keypads, to the newest cell phone app system that you can add to the alarm and activate / monitor the system from almost anywhere. All of these are available through the installation dept. at your Best Buy store. Good luck...
