I started a topic because I was having problems finding a shop that could install an add on alarm on my 2006 Impala SS. As it turns out, this seems to be an issue with any vehicle that comes with a factory installed remote start so I think it deserves a new topic.

I have a 2006 Chevy Impala SS. It comes with a factory installed security system and remote start. I thought that my vehicle was protected until I came out one morning to find my rims gone. Since the factory system doesn't include any type of shock, motion or tilt sensors it's useless in guarding against wheel theft.

I've contacted five shops now as well as a couple online sources (including this one) and am getting a different answer from all of them. Here is what I'm being told.

1. I can add an alarm system but them would need to use one key fob for the alarm and one for the remote start.

2. Before remote starting I would have to disable the alarm or it would sound.

3. I can use an add on system but it will decrease the range of my factory installed remote start.

4. I can add a new alarm and remote start and not use that factory systems at all and maybe it will work.

I've been going through this for 3 days now and still can't find anyone who knows what to do. Does anyone have experience with this who might be able to give me some information that I could relay to the shop? Better yet, is there anyone in the Detroit area that knows how to do it and would be interested in making some money?

Thanks

if it were my vehicle, i would go with door #4. you can add on an aftermarket alarm/keyless/remote start all in one (meaning one key fob) that will have 10x better range the factory alarm as well as more/easier add on options. maybe even a two way system if you park relatively close to your place

I've thought of going that route but it has its drawbacks. First off, it's obviously going to be more expensive. Secondly I'll lose the reature of my factory remote start which automatically adjusts the climate control based on the outside temperature. Lastly, nobody can even say for sure if it will work right. I would like the added feature of a paging system so it wouldn't be all bad. I'm just frustrated as hell because I can't find anyone who has done this kind of install before.

Hey, get the Hornet 727T

its a secuirty add-on

do a search on 727 and ull find some info about on the12volt

it uses factory remote

it has shock sensor

it also has another port with prewired harness for additional sensor like tilt or glass break

You can also disarm before remote start because there is a disarm wire on this system

Easiest & cheapest way for your problem

I have no idea what that is, but I assume an alarm tech would...lol. Thanks a lot, I'll take that to the shop and see if it helps.

That's the one I would like to get, just a matter of finding someone who carries it and knows how to install it on my vehicle.

My offer still stands to anyone in the Detroit area.

One problem a shop is going to run into is how to disarm the alarm when you activate the remote start. The Hornet alarm may have a disarm wire, but finding a wire to trigger it will be the hard part.

Your reply leads me to believe that this may be a problem that installers are just now coming across and that it may just take time before there are systems compatible with factory remote starts. Maybe I'm just better off waiting and hoping that a couple sets of locking lug nuts will be enough.

If i were to do this install, i would use igniton wire to power a relay to disarm the hornet 727T.

Is there any problem with this???

(nvr installed 727T on remote start system, only basic factory keyless entry)

Hey,

H2/7 Yellow/Black light flash monitor input

This input monitors the factory system light flash output and can be used as a disarm defeat wire

I assume the parking light flashes when it remote start?

if so, hook this up to the parking light wire and when you remote start it should disarm
