Compustar CS4900-S (4900S) 2-Way Remote Start and Keyless Entry System with 3000-ft Range

This remote start system is a solid option if you’re looking to add remote start and keyless entry to your vehicle. The 2-way remote is a nice feature because it confirms when the vehicle has successfully started. The range is impressive and works well from a good distance, which is especially useful during colder or hotter weather when you want the car ready before getting inside. The remotes feel durable and the controls are straightforward to use. Once installed and programmed correctly, the system works reliably and responds quickly when starting the vehicle. Overall, this is a dependable remote start system with good range and useful features for everyday convenience.

Used to replace a burned out bull dog system, motherboard. Installing this system was simple until the door locks portion. Prior system controlled the door locks without relays, this one not so. Vehicle installed in; 1995 dodge ram automatic 5.9 liter. Had electric door locks built in and triggered with negative current which with this unit requires two 5 pin relays. You'll be wiring two posts each to hot, one on each to vehicel existing lock and unlock wires, and to same coming from remote box. No posts go to ground. You have to test which end of the vehicles lock and unlock wire is going to the motor or coming from the switch after you cut the vehicle wires one being lock and the other unlock - you have 4 wire ends you tie into using the relay posts producing 4 wires and they need to connect to right existing lock and unlock ends and you determine the ends by using your vehicle lock switch to identify; hot = switch side, other by default is the actuator side. Then you can finish the wire connections. I went to manufacturer’s web site, training for installers and found a specific video instruction re: locks and relays-the instructor speaks the wiring pin to relay numbers arrangement. Takes notes and apply. Manufacturer sells a dual relay wiring harness or just buy two 5 pin. 4 pin won't work - 87a post is needed and 4 post doesn't provide. The rpm sensor i left in the default mode which is alternator or voltage sense instead of rpm coil sensor. Just wire sensor wire to relay hot wire source as it’s direct to battery and fused of course. As soon as it starts the rpm sensor which is intended to issue a signal back to the brains that the engine started is instead using the alternator sensor for volt signal increase. The remote will issue a confirmation tone that your vehicle didn't start so it kept the starter turning til it toasted out, caught fire and burned your vehicle to the ground....kidding of course but that could happen if there’s no signal to identify engines running, so wire that sensor, use the power relay source and fuse protect it. The burn to the ground wouldn’t happen, there’s a time out starter engagement limit so relax ladies and why are you reading this install review, he’s installing it. Lots of mod options to change attributes that you can program via remote key pad. Remote start is great, antenna pick up is great; hit the button, listen for confirmation, go back to bed for 15 or longer (programmable). If keyless is backwards as mine was it was caused by the motor wiring on one actuator is backwards. Good value, small unit, light weight, plenty of wire length, need two 5 pin relays on certain lock trigger type vehicles. Happy camper.

This is the second unit I have bought and have installed on both my truck and Jeep. The system is very responsive and the remotes feel quality and work very well. Each system's installation was simple and straightforward, and the wiring in the instructions is very clear. I highly recommend!

Got it To replace my key fab. Dodge's old key fabs fail Plus now I have remote start.

All and all, this has been a great purchase! Of course I didn't install this on my own, but I should have also purchased the Blade-AL bypass as well with this, since that was needed for my 2005 4Runner. My installer had a bypass, but not the Blade AL. What I love most about this remote start is the range, I've tested this from 300 meters away, and this has worked every time! What I like least, Compustar should provide two 2 way remote, and not one 2 way remote, and a backup remote that's only 1 way. All and all, I would buy this again!

TLDR? Don't get a Compustar. Get a Crimestopper. Even better, get the system from MyPushCart. They provide 100000% better customer service, and their smart phone module subscription is far less expensive, and with smart phone control, who cares about the fancy features Compustar offers? The install was easy. However, their customer service is terrible, and that's what the rating is for. I wanted to change the remote start runtime but the procedure in the manual doesn't work, so I emailed Compustar. They replied that the options cannot be changed via the remote. I let them know there is a table in the manual telling you how to do it, and then they said that's for the installer and they don't want end-users to change the options because it could blow a fuse. Seriously? In the end, I figured it out after Googling. You have to follow the instructions for the 1-way remote, and you have to do it while the key is out (ignition/accessories off). Also, the subscription fee for the Omega mycar smart phone module that mypushcart sells is significantly less expensive than compustar's drone. In fact, I'm about to tear out this system from my car to install a Crimestopper unit (the brand mypushcart carries) so that I can use the mycar module. See, I'm willing to uninstall and reinstall my remote starter because of my dislike of compustar. You like their features? None of that matters when you have a smart phone module where you can start, lock/unlock your car from wherever you want. Plus, you don't have to pay double for the GPS tracking system like you have to with Drone. Compustar thinks you're too unintelligent to install. They purposely left the incorrect instructions in the manual after all these years. I suggest buying systems from mypushcart. They actually help you! And their systems come ready for your specific vehicle. Also, Omega's customer support is excellent as well. Compustar takes so long to reply that you might as well...well, I'll stop here. Don't buy a Compustar!

I'm not a mechanic but I know my way around my vehicle to fix most things. If your vehicle has never had a remote start you'll need a pro to install this. There are no instructions on the box when I received it. I had looked up this start kit on compustar website and for my vehicle it said all I needed was I wiring harness to install. I took it to a local mechanic who's certified in my vehicle, and they couldn't install it. I needed more parts. So I took it to a pro installer and had to get what they called a blade for this to be installed. After spending another Benjamin on that and almost 250 in labor I have my remote start installed. Using it is simple, press the button to lock or unlock, press and hold to start the engine. It has a 15 minute timer to shut off the engine. Not sure if that can be reduced or extended, the timer was the same in my previous vehicle so that works for me. It also locks the doors when it starts the engine which is a bonus my previous vehicle didn't have. And it has the safety feature to kill the engine if the brake is pressed before the key is turned to the on position. Very happy with this purchase. The 2 way remote beeps at you when you lock or unlock the doors and plays a chime when the engine starts to let you know that action has been completed. The lights on the remote will flash every 30 seconds or so to remind you the engine is running. So happy I got this, b the day after it was installed we had a cold spell, single digits temps and a couple days of negative temps in the mornings. I didn't have to go out and freeze to start my Jeep. The 3000 ft range is strong enough to start the Jeep in my detached garage from my recliner.

As I mentioned, this seems to work well however there are some issues that I will voice here. *note, I have installed several remote starters in the past successfully with no issues but…. 1. Whoever wrote the instructions for this kit is extremely lazy, very minimal explanation on the inputs and outputs, and what they do exactly. 2. Lots of conflicting information in the instruction sheet. 3. They show that you can get a special connector (CN4) to connect to your trunk release as well as the door locks but they don’t provide a web link to order it and if you go to their website (Firstech), they don’t even list it, even a search will reveal nothing. 4. The tachometer input introduces noise into the wire which will interfere with your tachometer operation and create a fidgety needle. 5. The print on these instruction sheets is so damn small and very tough to read, especially when they crease the paper right over the letters.. Yeah this works but I probably will spend more money on a different brand next time

I stand by the compustar products. This model in particular works flawlessly in my International Durastar. It connects well with the drone, and any other compustar/idatalink system you want to throw in there. As a bonus, these units are compatible with all the IDataLink T-harnesses. So connecting to your vehicle can be an absolute breeze with the appropriate parts. ****BEFOR YOU BUY THIS**** Make sure you do some digging, check, double check, and triple check that it will work for your make and model. They have ALOT of different versions, and some are not compatible. The Compustar website will help you find a system formyour vehicle. The instructions however can be VEEEEERRRRRYYYYY confusing to folks. I'm an experienced HD field mechanic in Canada, and it was a pain to try and figure out how to rig this up with my unit. But once I got past that hurdle everything went smoothly. The recieved cable is perfectly long enough, the wires were too long for my application, but they may work perfectly for yours. I don't think you can go wrong with compustar.

Nice product. Very pleased

Perfect quality and so functional

Very easy to install and works as it should!

This remote start dose everything as stated. Awesome range with the two way remote. I have started my truck from 3 blocks away. I receive ALOT of questions (will this work with...) the quick answer is this is a universal remote starter, it will work with virtually any vehicle. It has more programable outputs than you could possibly need. (Standard, Diesel wait to start etc...) However dose require some knowledge/skill to install as you are tying into the factory wiring harness. Also most every vehicle requires an additional module/ key transponder wired in to bypass the factory security system. Over all very happy with the purchase and would buy it again.
