I have a 2013 4 door Silverado LT and am thinking of installing an old never used Astra 777 remote start. https://www.manualslib.com/manual/524025/Scytek-Electronic-Astra-777.html?page=15#manual

Above is a copy of the manual. If I get a box that holds a spare key so the security system can allow it to remote start, where does it wire into the Astra 777? I am a little unclear using the manual above. Any help is appreciated!

I have never used an Astra 777 unit. A quick review of the manual listed above indicates that the A777 is just a RKE and alarm system. It does have the capability to do the R/S function if the add-on StarLink Relay pack is added to the A777 unit. Do you have this module. Here is a link : https://scytek.net/main/files/manual/astra/startlink.pdf

The vehicle that you want to upgrade has a combo engine immobilizer system that consists of Passlock2 and PassKey3. Just using a spare key in a Universal key-in-the-box bypass module alone won't allow a R/S. The Passlock2 must be bypassed, too. Your best option is using an ADS AL-CA flashed with the ADS-AL(DL)-GM10 firmware (along with the StarLink Relay Pack). The ADS AL-CA will handle both immobilizers without losing a key and provide additional features. Before going that route, I would verify that your Astra 777 can support the StarLink Relay Pack via a Data Port.

Realistically, there are a lot of newer R/S systems out there that are better suited for your project.

What is something that is inexpensive with just remote start and door lock functions that has a good distance? I park a long way away from the building I work at. Preferably a two way so I know it has started?

Nothing is cheap right now, chip shortage and all that. Personally, I like the Compustar CS4900-S. You will need a Blade-AL cartridge flashed with the GM10 firmware. That will give you 3,000 foot range with one 2-Way remote and one 1-Way remote. Fairly simple install with about 10 wire connections to the truck. Figure about $220 for both.

How does this compare: Start-X Remote Starter for Silverado 2007-2013 & Sierra 2007-2013 || Plug N Pay || 3 X Lock to Remote Start || NO UPDATER Required https://www.amazon.com/dp/B0844MCF47/ref=cm_sw_r_cp_api_glt_i_T8VF3R929M7EAWBE0D60

The Start-X remote starter works by pressing the lock button 3 times on your truck's OEM key fob which means you will be limited to the range/distance of the OEM key fob and without two-way confirmation.

Simple install but does not meet your original requirements. It uses the factory remotes and three Lock commands in a row to initiate a R/S. So, no two way confirmation and the range is limited to the range of the Factory Remotes. Apparently, in an effort to keep it Plug-n-Play, it does not turn on the Parking Lights during R/S run time. I'm wondering if it even monitors the hood (on trucks without a Factory Alarm) to prevent a R/S during engine maintenance.

So trying to decide between the compustar mentioned earlier and the plug and play starter x. I would install myself. I have read compustar offers no help unless you are a dealer.

Any advice on which of the two systems with a self install?

Well, the Compustar CS4900-s is a bit easier to install than the Astra 777 with a key-in-the-box and some type of Passlock2 bypass.

The Start-X system is very simple and easy with its' total Plug-n-Play install.

Feature wise the Compustar wins, with its' long distance remotes, remote command confirmation, use of Parking Lights and other safety features.

Agreed that Compustar won't provide Tech Support for DIYers, not sure about Start-X but they do have some install videos. You would have to find an online seller that would flash the Blade-AL cartridge with the correct firmware (GM-10) if you went with the Compustar system. The Start-X system comes flashed and ready to go right out of the box.

What condition are the 8 year old factory remotes in and what range do they give you?

I’d go with this company. Also offers mostly plug and play but the system he sells with 2way remotes is $220 shipped. I’ve watched several of his install videos on YouTube and they are pretty detailed and easy to follow. Plus you can call and get support because he’s the dealer and should be able to help with any issues. Looks like there’s also an optional smart phone add-on for $130 if you want range from anywhere. Alternatively you could forgo the long range remotes and just do the smart phone app with the basic starter that uses your OEM key fob. Link for warmcarnow
