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

Perfect quality and so functional

Works great.

Nice product. Very pleased

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 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.
